Garrett GT15 – GT1548 – 200 HP


This is the biggest GT15 turbocharger that Garrett have. It's a 200 HP turbo and you see that it does not have the same turbine housing as the smaller Garrett turbos have like the GT12 and the two smaller GT15 turbochargers. The turbine housing here is the T25 turbine housing and that means you can use a T25 / T28 turbo inlet flange with this GT1548 turbo.

Recommended engine sizes for this is also 1000cc to 1600cc because of the small turbine housing. So it's a good turbo to choose if you are looking for 200 HP.

Model: 466755-3
CHRA: 431876-93

Bearing: Journal 
Cooling: Oil & Water 
Compressor
Inducer: 37.2 mm
Exducer: 48.0 mm
Trim: 60
A/R 0.48

Turbine
Wheel: 41.2 mm
Trim: 72
A/R: 0.35

And the GT1548 have both water and oil cooling so it's better that way also. The oil threads are the same M8x1.25 on the outlet. And with a single oil inlet. Click on the pictures to get them bigger.




This picture above is of an Garrett GT1549S turbocharger rebuild kit. If you have a worn turbocharger this is the parts that you would need to replace. This rebuild kit will also include the compressor and turbine wheel with the shaft. Most rebuild kits only give you the replacement bearings. The kit above includes.

Shaft and wheels. 1 x Journal bearing. 1 x Thrust bearing. 2 x Piston Ring (Oil seal).
1 x Compressor O Ring. 1 x Seal plate O ring. 1 x Thrust Collar. 1 x Thrust Flinger. 4 x Seal plate screws. 
5 x Turbine housing bolts. 4 x Compressor housing bolts. 1 x Shaft nut. 1 x Anti-rotation pin.
All this will set you back about 150 dollars or about 120 euros. And that's not a bad deal.


This is a video from a youtube user that shows two Rovers racing in Portugal. The Rover 200SDI (shown in the video)  have the stock Garrett GT1549 turbocharger and running 1.5 bar of boost. That's about 22 PSI of boostpressure and about 105 whp. The camera car is a Rover 220 SD also running 1.5 bar of boost but instead using the bigger Garrett GT2052 turbocharger.


There are many different versions of this turbocharger found in vehicles. I'm going to list a few below.

Hi,

Do you know what is the blade count of the turbine wheel of GT1548?

Thanks
Choon Seng

JD said...

Hello Choon Seng,

There are normally 9 blades on the tubine wheel on the GT1548 turbos (Turbo Code 466755-5003S). This makes the GT1548 turbocharger give a higher top end power because of the less restriction on the exhaust side.

However GT15s with Turbo Code 433290-0042, 433298-0042, 433158-0001 and 433290-0004 all have 10 blades on the turbine wheel. The extra blades allow the turbocharger to spool a bit better but also restrict the exhaust and give less top end power.

There are also bigger and smaller turbine wheels made for the many variations of the GT15 turbo with the difference being 1mm in the major diameter size 41.2mm up to 42.2mm.

If your turbine wheel measures (smallest diameter) 32.2 mm and (major diameter) 42.2mm then you should have a 10 blade turbine wheel installed.

Hello,

Thinking of turbocharging my 1000cc city car, and the garrett 1544 and 1548 seems a pretty spot on choice rated 1000cc - 1600cc. My amateur choice leaned a bit on the 1548 as it offers water cooling, which tells me it will be more durable, than 1544 without watercooling. Assuming they both set to produce the same boost. However, the engine list shows that the smallest engine displacement the 1548 ever installed was on a 1.9litre engine. While the 1544 on a 1.4litre. That makes me hesitant picking the 1548. Any idea which should I choose for my 1000cc engine? Does the 1548 takes more pressure to spool, more lag, etc? If not, i'd rather go for 1548 as it is water n oil cooled and can be tuned for more boost. Please help.

JD said...

Hello Randy

Well the GT1548 being water cooled makes it a bit more durable however it is also bigger and will take longer to spool on your 1000cc engine. The GT1548 will make around 50hp more than the GT1544 at 1 bar boost pressure.

If you want watercooling then you could try and find the Garrett GT1241 turbocharger
http://turbochargerspecs.blogspot.com/2011/02/garrett-gt12-gt1241-130-hp.html

It's the "smaller" GT15 and a little bit smaller than the GT1544 but not by much. And the GT12 will give you water cooling and also a bit quicker spool.

I say if it's going to be a city car I would go with the smaller GT1544 or GT1241 instead, because the smaller turbochargers would come on boost quicker and make more low to mid range power that's more used in the city.

But as long as you take care of your turbocharger and take a minute, to let the engine idle before shutdown to let the oil cool down the turbocharger you should be fine with a non-water cooled turbo. Most people that don't have water cooled turbochargers install aftermarket turbo timers. And today even most aftermarket car alarms have a turbo timer option.

Hi
What is the hub-tip ratio or the hub radius of the compressor impeller of the GT1548? Also what is empirical value for the boundary layer blockage used in the inducer design?
Thank you for your time

JD said...

Hello Mitchell,

I was able to get measurments off my GT1549 Garrett turbocharger and the hub radius on that compressor wheel is 5.75mm. I can't get the boundary layer value but the inlet on the inducer is 40.20mm and this goes down 19.40mm from the inlet to the compressor wheel hub (it is still 7.8mm down from this point to the compressor blades). At 19.40mm the inducer should be around 37.2 mm all the way down as stated in the specs by Garrett.

The exducer on the compressor cover is 32mm internally. These are all the values I could get. Hope this helps.

Unknown said...

Thank you for your help JD these dimensions were helpful.
Would I also be able to get the blade thickness on the compressor, the exit angle of the blades (if you were looking axially at the compressor impeller) and the streamline angle of the blades (the angle of slant // looking from a radial direction)
Thanks again for your time

JD said...

Hi Mitchell, no problems glad to help. I tried to do some more measurements for you but the calipers are too big to even get the blade thickness.

If I had to guess the blades are only around 0.7mm not even 1mm thick. And the angle of the blades probably around 35 degrees, this is only from looking down the inducer so I might be off on that.

Can't really get any more than this without having to remove the compressor cover. But if you really need some solid numbers you should be able to pick up a used GT15 turbo pretty cheap. The GT15 turbocharger have been used in so many different cars and models that you should not have a problem finding one to take apart. And when you do there are only four bolts to undo and you can lift the compressor cover off and expose the compressor wheel.

hello,

first of all, are you portuguese? if yes you can answer in portuguese because i am also.
Secondly, are there any diferences between diesel turbos and gasoline turbos?
i am looking to modify a 1600cc gasoline engine, and i have got a GT1549V from a BMW 320d (e46)just wanting for some use in the garage, so i was thinking if there is any problem using it and wondering what kind of power should i get from it...

thank you.

JD said...

Hello Gonçalo, yes a Diesel engine need more air than a Gasoline engine to operate, and because of this the turbochargers for Diesel engines also need to be larger to supply enough air.

The Diesel turbochargers also need to be made more efficient because the exhaust gases are also colder on Diesel engines. So that is why we normally see the 2-300hp Diesel turbochargers like the Holset HX35 or HX40 turbos on 5-600hp Gasoline engines.

I think the GT1549 turbocharger should be good on your 1600cc engine it will spool fast and you will probably get around 170hp without problems and with a good engine 200hp with 1.4bar boost pressure. Anything over 1.5bar boost with this turbo and you won't get much gain in power.

Unknown said...

Hi
I am looking to replace my GT1544 turbo and I am wondering if the GT1548 would be a direct swap. My problem is that its a 1.9td (ABL Engine Code) VW t4 with not much power, however I am increasing the fuelling as well as an engine rebuild so a larger turbo would be needed. I am able to make adaptor plates for it too if necessary.

Any info would be greatly appreciated

JD said...

Hello, in short the GT1544 and GT1548 turbos wont be a direct swap. Both the turbine inlet and outlet flanges are different. The GT1548 turbocharger being a T25 turbine inlet so you would need to make a custom T25 to 3 bolt flange adapter. However once you have sorted all that and made the engine accept a T25 turbocharger, then you would have more turbo upgrade options that are direct swaps in the future if you want to try even bigger T25 flange turbos.

JD said...

Hi serkannn, you need a bigger turbocharger like the Garrett GT2056 or GT2259 turbo if you want to get over 200hp with a Diesel engine. The GT2259 turbocharger would be a bit more laggy because the turbine is bigger but it will also let you rev the engine higher. The GT2056 turbo have a smaller turbine so it will come on boost quicker but also won't give power as high in the rev range.

serkannn said...

Hi jd thanks my frıend :)
We have made the original 2056's put garret turbo to turbo garret hybrt 1244vz hybrt 1200 revolutions have always come from these wear we wonder how many thousands of revolutions 2056 rpm is more of a loss do?
come in until 2000 rpm to 4500 rpm edermi?

JD said...

Hi serkannn, I would guess the GT2056 to come in around 3000-3500 rpm on the 1.6 TDCi engine and give you good power to +4500 rpm.

Unknown said...

Hi JD
I have a volvo v40 1.9 diesel 2002 with 115hp and I want to add some boost. I think it has the gt1549s.
What turbo swap would you suggest without losing lots of engine reliability?

JD said...

Hello tassos, in your case I would pick the Garrett GT2056 turbocharger because they work very good on 1.9 liter diesel engines.

PhoeniX said...

Hi JD,

I own a 1.4tdi engine with a gt1544s (80cv), and I would to reach it up to 200cv trying as possible don't loose to much kick down. Do you think that this one could help me?

The project includes bigger injectors, FMIC and new map, of course. The only piece that I miss is a turbo wich get kick down as near as 1544's possible. Thanks

JD said...

Hi PhoeniX, the 1.4tdi Diesel engines do spool good with the Garrett GT1749V turbochargers. The GT1749V should give you full boost around 2000 rpm. But you get max around 160hp with the GT1749V turbo.

To get close to 200hp you need something bigger like the Garrett GT20 VNT turbo or Mitsubishi TF035HL turbo. However with these you will not get full boost until around 3000 rpm.

PhoeniX said...

Hi JD,

Thanks for response. With the GT1749V I need to swap geometry, n75, remade the map..... I know Vs are best than fixed, but adapt geometry, i think that is pretty tedious... and too much expensive! hehe

A friend could reach his 1.4tdi up to 180hp with a 1749vb few years ago, but he made the geometry conversion. I'd like to try make it without that.

could it be a fixed turbo to get that power, or closer, other than a V one? Thanks

JD said...

Hello PhoeniX, in that case you should look at trying to upgrade the compressor wheel on the GT15 turbo to a bigger one. For around 60 Euro Mamaba makes a 41mm billet compressor wheel for the GT15 turbo that should flow the same as the GT20 turbochargers. However there is a possibility that because the turbine exhaust side is smaller on the GT15 it might restrict the power some. But if not you should see 200hp.

The only downside is the 41mm compressor wheel is around 4mm bigger than the stock GT15 wheel so the GT15 compressor housing needs to be machined for the wheel to fit. But if you can find a local machine shop to do the work it should only take them 1-2 hours to machine the compressor housing.

Mamba also have a 39.86mm compressor wheel that might spool a bit quicker than the 41mm but there would be a 15-20hp difference.

Hi JD,

So with this info I'll talk with my mechanic, to see what can be done.

I'll come back to report the results :) thanks for all! Cheers!

Unknown said...

Hi JD,

I have a 2008 renaultsport R26 2.0L Petrol Turbo.
The car is running on stock parts, with minimal mods.
The exhaust is decat, and I have a K&N panel filter fitted. It is currently tuned to a Stage 1, cranking out 265bhp.

I am looking at upgrading my turbo but am lost at how to go about it.
Is there any aftermarket Turbos that can bolt directly onto my engine which will provide higher HP preferably something up to 320-380bhp.
Please advise me.

JD said...

Hi Warren, the thing with the Renault Megane r26 is they come with MHI turbochargers. These have a round 3 bolt flange for the turbo different from a t25 flange that you would need. You would have to find someone that makes aftermarket manifolds to fabricate a t25 flange manifold to fit either a GT25 or GT28 turbo. Or you could try and make your own 3 bolt to t25 adapter plate for your stock manifold. Either way it looks like a custom job. Also remember that the stock injectors are only good for around 290hp so these would have to be upgraded if you want anything above 300hp.

Smuggler said...

First, I would like to thank you for a good site!
Have found a Garrett GT1549S from a 115hp SAAB 9-3 2.2 TID -99 will it be too small for my project?
Does it differ slightly on the compressor map between the GT1548 and GT1549S?

A little short about my project:
MB 240D 2.4 liter boat engine 4-cyl OM616.918
Water-cooled exhaust gas with heat exchanger
Fairly fat water / seawater cooled IC
Double seawater cooled oil cooler
Dieselmeken pump for about 130hk and refurbished diffuser
Original effect 72hp at 4400 / rpm, 137Nm at 2400 / rpm
Comp: 21: 1

Will have it in a 20ft DC weighing about 1.3 tons, aiming at approximately 130hp at about 4400rpm and 1-1.3 bar charge pressure giving a top speed of about 30 knots with a 20 "propeller.
Marsh speed is estimated to be about 3000-3600rpm and give a speed of about 20-25 knots.
The planing threshold is between approximately 2000-3000rpm where it would be desirable to get good power up in planing even with full load.

Think that a WG turbo is preferable as it is harder to solve the control of VNT?
Advantage of a smaller turbo if it is less energy in cooler exhausts when mainfold is water cooled

JD said...

Hello Smuggler, thank you. No I don't think the GT1548 and GT1549S are too different on the compressor map, at least the one I have measured a GT1549S from a Volvo have the same 37.2 mm inducer size.

The one issue I have is your engine being a larger Diesel 2.4 liter engine and the G15 exhaust housings are very small, 48.0 mm Exducer. Because of that it might choke the engine a bit especially above 4000rpm. However this might not be a problem for you if you are cooling the exhaust gases.

The other choice for you would be the GT2052 turbo it has a slightly larger compressor inducer but a much bigger 52.2 mm exducer.

Actually if you want to run a VNT turbo there is now a standalone turbo VNT Controller that you can buy from UK. I don't know all the details but I'll link it here.

Hi JD,
First of all thanks for such a great page. It has great information. I have really come a lot closer to what i was searching for past couple of years.
I live in india and drive a suzuki baleno which is naturally aspirated mpfi 1.6ltr petrol engine, generating 94hp@6000rpm. I am thinking to turbocharge it.
Now the problem is that in my country we dont get parts according to part numbers but according to vehicle. And in our country petrol turbos are still a far fetched thought from manufacturers, but diesel have plenty.
And traffic conditions here are such that you are never able to cross 2000rpm in top gear in city. So i am looking for a turbo that should spool up by 1200rpm and i dont care if it stops giving power even at 3500rpm. And i am thinking of a 50percent increase in power, around 150hp@6000rpm.
So after reading your page i have narrowed down my search to a few diesel cars, please guide me selecting one if it is possible this way.
1. Ford figo tdci - 1.5ltr, 100hp@3750rpm.
2. Skoda octavia tdi - 1.9ltr, 90hp@4000rpm.
3. Renault duster1 diesel - 1.45ltr, 84hp@3740rpm
4. Renault duster2 diesel - 1.45ltr, 110hp@4000rpm
5. VW polo tdi - 1.5ltr, 108hp@4400rpm.
Thanks and regards
Mehul

JD said...

Hello Mehul, thank you.

I think the cars you listed use the Garrett GT1549S turbocharger, at least I see the Renault Duster 84hp have the GT15 turbo. The problem however is I'm not sure you would spool that turbo at 1200rpm, maybe around 1800-2000rpm it would spool and give you power.

A smaller turbocharger would be the Garrett GT1238S turbocharger found in SMART Fortwo 0.6L Diesel cars. That would spool up no problem however you would lose some power because it's only a 130hp turbo around 0.7bar boost. Maybe you could get 140hp if you are lucky at around 0.8 bar boost.

So at the moment there is nothing between the GT15 and GT12 that would give you the best of both worlds.

In short, if you go with the GT15 turbo found in the Renault Duster you would make 150hp on problem but probably not build boost as early as you would like. If you go with the GT12 found in the Smart Fortwo you would build boost really quick but not be able to make the 150hp you want.

If you can't find the GT12 turbo and go with the GT15 you might be able to make it build boost earlier if you keep the turbo manifold as short as possible or use really small 25-30mm inner diameter tubes.

mehul said...

Right sir, my sincere thanks for such an elaborate and clear reply.
And wow..! I was assuming that to spool up a petrol 1.6 and achieve 150hp you will ask me to go for skoda tdi 1.9 or bigger diesel engine's turbo. But as you explained that GT15 will help ke achieve 150hp but spool late and GT12 spools at 1200 but i wont get 150hp.. So i am really in a fix now..
Sorry to pester you, but then I have a few more options available in diesel in my country..
1. Chevrolet beat diesel - 936cc - 58hp@4000rpm.
2. Ford fusion/fiesta/ikon- 1.4tdci- 68hp@4000rpm.
3. Fiat punto/linea diesel - 1.25ltr- 70hp@4000rpm.
4. Skoda fabia diesel - 1.4tdi - 69hp@4000rpm.
Will any of the turbos used by these cars can fulfill my requirement and give me best of both worlds?
Thanks and regards

Hello mehul, I have been looking at the 68hp Ford 1.4tdci engines and they have the KKK KP35 turbocharger. I can't find the compressor map for the KP35 turbo to give an exact hp number, however looking at the compressor wheel size it does have a 31mm inducer.

Now if you have been looking at the Garrett GT12 turbocharger you might notice the compressor wheel is a little bit smaller 29 mm inducer (130hp). And if we have a look at the Garrett GT15 turbocharger it has a 32.9 mm inducer (150hp).

So going by the size I think the KKK KP35 turbocharger would give you a bit more power over the GT12 turbo, I'm not sure how good the KKK spools but it would be better than the GT15 turbocharger.

Also I have mentioned before that Diesel engines always run higher compression ratios, like the Ford 1.4tdci have a 18:1 compression. And most petrol engines like the Ford Zetec run 9.5:1 compression. This means a Diesel engine always need more air and bigger turbo (around 2 times) to get the same power.

And you can get an estimate from that, the 70hp Diesel turbo (18:1 compression) should be able to supply air to get 140hp from a petrol engine (9:1 compression).

But not all Diesels have 18:1 compression, some have 14:1 and others can have 22:1 compression. But you can use this and make a good guess at what power a Diesel turbocharger can achieve on a petrol engine.

Hope this helps.

Hi, do you have any idea about the dimensions of the turbocharger on the BMW 116i/118i? It is labeled as MGT1549ZDL, can't find any info on this

JD said...

Hello Nick, the compressor and turbine housings are different on the MGT1549ZDL turbocharger.
From what I can tell, these should be the parts numbers and dimensions for the BMW 116i (F20) Turbocharger.

Part numbers
(updated) 820021-5001S
(old version) 820021-0001
(updated) 11627633925
(old version ) 11627645759

Compressor wheel number 786556-0002 (replacement wheel)

Compressor Inducer Size 36.3mm

Compressor Exducer Size 49mm

Compressor tip hight 4.4mm

Compressor wheel height 26.4mm

Blades 6/6

Unknown said...

Thanks a lot of the info mate, i couldn't find it anywhere. What would you recomend as an upgrade? The same engine has much more powerfull versions, the MINI Cooper S JCW with the BorgWarner turbo is an example and that has a compressor wheel that is 41mm/51mm, rated at 210hp from the factory, and then there is the Peugeot 308GTi/RCZ R version that has 270hp but i don't know the turbo specs for that one

JD said...

Hi Nick, what I can find is the Peugeot 308 use the KKK K03 turbochargers same as the Mini Cooper however I'm not sure if the newest 270 hp models use that same size turbocharger.

The KKK K03 turbos on the early 2010- engines do hit full boost very early around 1 bar at 1700rpm, and gives around 200 hp. But the downside is the small turbine size don't allow the engine to breath higher up in the rev range so the boost pressure (and power) drops off.

The biggest issue I see is the turbine housing and exhaust manifold is an integrated design both for the KKK K03 and MGT1549ZDL type turbos so there is no easy upgrade because of that.

There's a turbo upgrade done with a TD04-19T turbocharger for the Peugeot 308 and other BMW engines that gives around 300 hp however I'm not sure if it is a straight turbo swap due to how the stock exhaust manifold is done on these engines.

This is an upgrade option for other BMW models using the N20 turbos (with manifold)
(BMW 116i/118i use the F20 version)
http://shop.mambatek.com/product.sc?productId=2209&categoryId=-1

N20 turbo (Without manifold)
http://shop.mambatek.com/product.sc?productId=2232&categoryId=-1

Then this is the upgrade for the K03 Peugeot 308 (without exhaust manifold)
http://shop.mambatek.com/product.sc?productId=3001&categoryId=-1

I guess if you are able to fabricate your own custom manifold then you would have more options, or if you can find a stock 308 turbo manifold then you would have the GTX turbo upgrade option.

I know this is old but i need real help bad and you sound like you know whats up.
I have a 2010 ford flex limited with the 3.5l ecoboost engine.
I was told that it has garret/Honeywell gt15 water coold/oil cooled turbos.
I must find turbine shafts for my stock ford flex/sho ecoboost turbochargers.

Can you help me?
How do i figure out what other shafts will work with them.
I dont need the stock blade count bu I'd prefer it .
I have already purchased BILLET COMPRESSOR wheels.
But my shafts are out of spec to much .
Please help if you can .
Thanks alot..

JD said...

Hello, sure no problem, I still reply to questions.

It looks like the 3.5l Ford Flex does have twin Garrett turbochargers but they are Garrett turbos made for Ford. It will say either Ford or FoMoCo on the compressor housing. So they have some different specs than the standard Garrett GT15 turbos, like a slightly smaller turbine.

Also another big difference is the passanger side turbocharger is a reverse rotation turbocharger, so that would need a different reverse turbine / compressor etc..

From what I can gather the stock FoMoCo turbo compressor inducer size is 36.3mm and exducer 49mm. The stock turbine inducer is 40mm and exducer 34.5mm.

The following are part numbers for the Ford 3.5l Ecoboost FoMoCo turbochargers (check they are correct for your engine)

Rightside turbo
FoMoCo
S/C GHYFA
S/N 110733
P/N BL3E 9G438 VA

Leftside turbo
FoMoCo
S/C GHYFA
S/N 110216
P/N BL3E 9G438 UA

I can't find any turbine shafts sold separate, however there are CHRA complete center sections for sale like this that are not too expensive if you can't find any shafts.

Tom said...

hi
I have an Alfa Romeo Giullieta 1,6 Diesel 105cv. the car now has
remap
egr/dpf off
custom intake
FMIC and hoses
full custom exsaust 63mm (2.5inch)
BMC air filter.
I want to make hybrid turbo. the turbo is garret gt1446sz. I found 2 options of billet whell.37.10/48 6+6 or 35/48 11+0. what is the difference of these 2 wheels? do I have to do something on turbine wheel also? I dont like to loose torque and response at low rpms. i spoke with a guy who replace the turbo with gt17 and has full boost at 2700 rpm. I dont like that.
Thanks in advance and sorry for my English.

JD said...

Hello, no you don't have to do anything to the turbine wheel it will be fine. I think the best billet wheel for your hybrid turbocharger would be the 6+6 blade 37,10mm inducer wheel. The 6+6 blade configuration wheel will flow more air so you would get more power than the 11 blade wheel.

However the 35mm 11 blade wheel is also smaller and probably a bit lighter so that will make it spool a bit faster, but you won't get more power.

I would still go with the 6+6 blade wheel but if you want the best possible response at low rpms then the 11 blade wheel might be the better option.

I can't really say how much difference there is between these two compressor wheels, but since the compressor wheels are not that expensive you could try the 35/48 11+0 wheel first and if you still want more power you could switch to the bigger 37.10/48 6+6 later.

However you won't be able to go back to the smaller 35mm wheel if you do the machine work on the compressor cover and fit the bigger 37.10mm wheel..

Tom said...

Thank you very much for your help. Do you have any idea for the dimensions of the stock turbo? Gt1446sz

JD said...

Hi Thomas, I did search for the dimensions of the stock GT1446SZ turbocharger however I could not find much. My best guess is the dimensions on the compressor wheel to be around 34-35mm. I have part numbers so you can look them up if you like.

And there is a seller in Latvia that have unbranded stock GT1446sz compressor wheels for sale with a long list of different vehicles that also use the same turbocharger.

Sam said...

Hi JD
I’ve been reading through your posts and your very knolagable and was after a bit of advise.
I have a Vauxhall Vivaro 1.9dci which has a GT1549 as standard, the van has got a straight though exhaust, egr delete, custom intake and a remap making 140bhp.
I want to upgrade the turbo next, on one of your earlier posts a guy had a 1.9td and you mentioned a GT2056. So I’ve done my research and it turns out that Vauxhall make a 2.5dci Vivaro which is fitted with a GT2056. I know it won’t be a direct swap but was wondering if this would be a good starting point in your eyes??
Many thanks Sam.

JD said...

Hello Sam, that sounds good. If you can find the 2.5dci GT2056 turbocharger you might only need to make some changes to the intercooler piping. I can't confirm this but it looks like Vauxhall have the same 3 bolt flange on the GT1549 to the turbo and also the exhaust might be the same on these two turbos.

Unknown said...

Hi There, first off all, congratilations for this wonderfull blog. I have an 2000 Renault laguna 1.9 dti estate, and for what ive seen comes with a gt1549 as stock, 98hp. A bit short for my needs, i dont want to go over 150hp, so replace The turbo for a better or changing billet (as ive seen kinugawa) would be on The list. It has natural FMIC, i did a dyi muflerectomy (Thats wen i noticed Renault has this muffler restricted) and maybe repro. On other posts ppl sugests the gt1749 from Renault 2.2dt, but The gt1548 wathercooled sounds interesting, what would you sugest? Thank you in avance.

JD said...

Hello, if you can increase the boost pressure with the stock turbocharger to 22psi or 1.5bar boost you could get around 120hp with the GT15. I'm not sure however how well the Renault 1.9 dti engines responds to increased boost pressure, or if the Diesel pump can supply the extra fuel needed from stock. So you might need to do a remap or modify the pump, or if the Renault 2.2dt injectors / pump fit the 1.9 dti engine you could do that.

The GT1749 would be a good upgrade because that turbo will flow more air and would be able to give you around 140hp at around 15psi / 1 bar boost. You can get close to 150hp but you would probably need to run around 1.2 bar boost then with the GT1749.

Watercooling is not super important considering it's a Diesel engine and it runs cooler, just make sure you leave the engine running a few minutes before you shut off the engine to let the turbo cool down.

Tom said...

Hi JD
What bigger turbo can I install on my alfa Romeo gulietta 1.6 diesel? Now it has a gt1446sz not variable. The guy that make me the remap told me that is difficult to replace it with variable geometry. Do you have any idea?

JD said...

Hello Thomas, I would go with the GTB1549V turbo if you can find a good one. It gives full boost around 2400 rpm 400nm on the Alfa 1.6 jtdm engines. And you can get close to 200hp (around 160whp) if you run 2 bar boost pressure.

If you go with an even bigger turbo like the GT1749V you would not get that much more power and on the Alfa 1.6 engine it would also spool up a bit later.

Here's a video with the GTB1549V turbo - Alfa giulietta 1.6 105 cv gtb1549v 2 bar 1.8@5000 rpm. Edc17c49 ecu

Catalin said...

Hello Jd! For 1.5 dci 65 hp a gt 1549 s will be good for 120 hp? Will the small diesel be able to get full boost at around 2000 rpm? The exhaust flange looks similar, not sure it'll be bolt on, but with some small mods might be doable. Thanks

JD said...

Hello Catalin, it looks like the 65 hp version of the DCI 1.5 engine have no intercooler while the more powerful 85 hp and 100 hp versions of this same engine have intercoolers and minor changes to the turbochargers.

So first you would need a intercooler fitted if non is fitted. Also note that the 85 hp version of the engine have stronger pistons, rods and crankshaft, so increasing the power on the 65 hp version can result in failures due to it having weaker internals.

Now if you still want to try and boost performance I would expect you to reach around 100 hp with the GT1549 on this engine, however you probably will need to run around 1.3 bar boost on your engine. But you will need to increase the Diesel pump pressure and possible replace the injectors with the ones from the 85 hp version if you find you need to add more fuel to get the power you are after.

You could potentially reach 120 hp if you run even higher boost pressures however I am not sure the stock 65 hp pistons can handle that much power.

Catalin said...

Hello Jd, thanks for your reply! I'm aware that i'll need intercooler on my lump and i think that anything over 100 hp won't be that reliable but the only differences between 65 and 82 hp is intercooler, 0.2 bar and tune on euro 3 engines, also my engine already has 419000 km on it and the last 40000km were made at 1.1 bar on kp 35 turbo so if i'll kill it won't be too much of a deal. My doubt is how much lag the gt1549 will have over the stock kp 35 and i don't think i'll run anything over 1.2 bar. If you think it's too laggy tell me please i'll keep the stock one with tune and intercooler. Thanks

JD said...

Hello Catalin, it won't be too laggy over your stock turbo. Consider at least 500 rpm difference on your engine. But it really depends on how you can tune the engines Diesel pump, if you can get it to pump in some extra fuel on "kick down" it would help spool the turbo even better.

You can start by playing around with the Diesel pump diaphragm chamber / boost compensator needle. I'm not sure if the DCI have this type of setup but you can read this paper on Diesel pump tuning to get a better understanding.

Tom said...

Hi JD
I need your help once again. For a turbo which has a compressor wheel 31/46 6+6 to make it hybrid with billet I have two choices. 35.7/46 6+6 or 34.1/49 6+6 which of the two is better on low rpms torque and less lag. What's the difference between bigger or smaller exducer 46 or 49mm
Thanks again for your help

JD said...

Hello Thomas, the 35.7mm inducer compressor wheel is going to flow a bit more air and give you some more power, it's going to be more efficient at lower boost levels around 15 psi / 1 bar boost and also if the overall weight of the wheel is less then it's going to have a bit less lag also.

But since the exducer is smaller at 46mm it might not be as efficient and flow air well at high boost pressures. You could go with the 49mm exducer compressor wheel because you can expect the bigger exducer compressor wheel to be more efficient at higher boost pressures like +20 psi / 1.5 bar boost.

The bigger exducer wheel would build boost pressure quicker due to it having a higher wheel edge speed, but if the weight of the wheel is more it also will play a role in how fast it is able to build boost. But in this case since it's going on a Diesel engine and most likely be running higher boost pressures the 34.1/49 6+6 wheel might be better overall and give you less lag.


Tom said...

Thank you for quick response
I have already ordered the 34.1/49.
Another question is do you think that the 1752 vklr will have full boost late on a 1.6 diesel engine? I found this in good price used from the gulia 2.2 and I am thinking of it. I read also that ball bearing turbos is less lagy is that true?

JD said...

Hello, I would expect the GTD1752 to hit full boost around 2500 rpm on a 1.6 Diesel engine, a good setup might get full boost a bit sooner. Ball bearing turbos usually spool a bit faster by around 500 rpm vs an equal size journal bearing turbo. So it's not that big of a difference in initial spool.

However a bigger ball bearing turbo can also feel more laggy when driving because of how the power comes in quicker and you get more of that old school "on/off boost" feeling vs a similar size journal bearing turbo that starts to build boost, spool up and the surge of power comes in a bit slower and controlled.

Unknown said...

Hey, I love this page! It's been such a good resource.

Anyways, I have a bit of a dilemma:
I have a 995cc 3 cylinder port injected gasoline car, rev limit 6500, peak torque around 4-4.5k RPM .I currently have it turbocharged with a GT1241 turbo and using a large front mount intercooler, running .75 bar boost . The problem is that it just feels like it's too small and that I may be leaving power on the table.

I'm thinking the 1548 would be a better fit. Any suggestions? This car is street driven, so I don't want a load of lag , but would like somewhere around 85kw .

JD said...

Hello, looking at the two turbochargers you should be able to get to 85kw with both the GT1241 and GT1548 turbo. But you need to run more boost, around 1.2 bar boost would probably get you to 85kw on the GT1241 turbo. If raising the boost pressure still doesn't help with the GT1241 turbo then going with a 2" downpipe and exhaust from the turbo might help.

If you still feel the GT1241 turbo isn't giving you the power you are looking for then the bigger GT1548 turbo might be the best option since it's bigger turbine housing will flow more and it will be able to give more power all the way to the rev limiter. I would expect a bit more lag over the GT1241 but only about 500rpm difference.

Unknown said...

Hello JD, I am having a stage 2, 1.6 tdi running with BV40 turbo producing around 175-180 BHP with 350 nm torque. I am planning to upgrade to next level but confused to opt between the following
GTC1549
GTD1752
I drove a polo running with GTC1549 and powering around 200bhp/400nm and i liked the setup. But i also read a lot of good theoretical reviews about GTD1752 but never got a chance to drive any vehicle equipped with it.
Could you let me know the differences which i may feel if i opt for GTD1752 instead of GTC1549 ?

JD said...

Hello, both the GTC1549 and GTD1752 are similar with both capable of 200hp however the GT1752 can be pushed a bit further to around 230hp while having the same spool and drivability especially on bigger 1.9 - 2.0 liter engines.

However on smaller engines the difference is going to be a bit more noticeable and to get the same drivability can be more difficult. In your case since you have a 1.6 liter tdi engine you should expect to lose some spool if you go with the GTD1752 over the GTC1549 turbo. The GTC1549 turbo should come in a bit sooner and spool around 2400rpm while the GTD1752 might take 300rpm longer around 2700-2800rpm depending on setup.

But with a good tune you could get that spool down to 2500rpm. If you are looking for more power than the GTC1549 can provide then the GTD1752 turbo probably is the best option even if you lose a bit of spool. But if drivability is most important I would pick the GTC1549 turbo.

Thealtoviolist said...

Hello there! Love the blog, very helpfull.

I want to fit a turbo into my Ford Fiesta (1.6 8v rocam, iron block, engine swapped from Ford StreetKa). As it is a 1.6L 95hp, and stock internals, GT1548 would seem ok. BUT. It's PETROL engine, and I see only GT1549 for sale, from diesel engines. And they are only oil cooled. Couple of questions:
1) Are they the same as 1548 mentioned here? I doubt I'll benefit from GT20xx, 150hp will be already great.
2) How much of the difference will it make, to run only oil cooled version? Would love to find water-oil version, to be on the safe side, but it may be difficult to get one.
3) Do you know wastegate pressures for 1548? I have stock internals, heard that 0.5-0.8bar would be relatively "safe". And i don't have to make 200hp now, maybe later, with forged internals, if I decide to be that crazy with this old engine :D
What do you think? Thanks for any suggestions!

JD said...

Hello Thealtoviolist, it's mainly the turbine housing flange that is different, but there are also water cooled GT1549 turbos that SAAB use however on these they instead have a combined manifold and turbine housing.

You should however be ok with only the oil cooled version as long as you take care and do the proper turbo cool down period.

The stock wastegate springs are set to 10 psi / 0.7 bar so you should see around 150-160hp.

Unknown said...

Good day. Seems you have the answers to pretty well any turbo questions.i have some 1uestions, I have a 2001 Harley Davidson sportster 1200. I'd like to turbo it but very little info online due to the fact few have done it. I'll be building a custom turbo header. Running a draw thru carb (mikuni hsv45) engine makes power between 1800-6800 rpm in N/A form. I need a turbo that when facing forward the cold side mates to the right side of the engine, with cold side exit at the top side of the turbo and exhaust entering in from the bottom, exiting towards the rear. I've heard exhaust inlet can't be smaller than 1.75" otherwise it will have to much back pressure and loss on the top end. What turbo, a/r, and trim would you recommend. Is there a common turbo that would spool with a 1.2L engine? A T25 flange looks like it would be about right based on the exhaust pipe sizes, but feel like a T25 wouldn't spool..

JD said...

Hello, you should be fine with 1.75" pipes going to the turbo. With the right tune the GT1548 or GT1544 turbos should spool no problem, but the 0.34 a/r GT1544 would be the best for minimal lag. You can rotate the compressor and turbine housings on almost all turbos for best fitment.

However if you really need to have the compressor outlet facing the other way around on the engine then Garrett have come out with a new G25-550 turbo that is also available with Reverse Rotation. However that turbo is for 1400cc to 3000cc engines and more suited for the 300-550hp range so it would be a bit too big for your engine.

Hi JD, i have a Mitaubishi Canter with 4D33 4214cc N/A engine, 128HP/2000 RPM. I need to Bolt On Turbo for this engine, and try to find any suitable turbo for low power band, spool from 1000 to 2500 RPM and normaly iam driving not reach at 3000 RPM..
And need a whistle sound too, any suggestions 😊😊

JD said...

Hello, you could go with the GT1548 turbo, it should spool just fine from 1000 rpm and give you around 40-50hp more power and torque at low rpm. If you want a bit more power you could get the GT2052 turbo, but it will also be more laggy and slow to spool at low rpms so in that case not as good as the GT1548 turbo for normal driving.

flyways tnt agency said...

Hi JD, thank you.

flyways tnt agency said...

Hi JD. I have another customer. Use a 1JZ VVTi single turbo engine. Original toyota turbo is broken,and this guy put a after market A/R60 for Compressor and A/R63 for Turbin, but no power at low RPM.
Customer ask to me, need one new turbo same spec with CT15B ( i think) from IJZ VVTi engine.
Please advise a suitable garrett turbo same like CT15B?

Thank you

JD said...

Hello, the closest Garrett turbos that match the Toyota CT15B turbocharger would be the 60 Trim GT2560R turbo or either the 55 Trim GT2860R Part number 707160-7 or the 62 Trim GT2860R part number 707160-5.

Also the GT2860RS Disco Potato turbocharger would be a good Garrett replacement however these can be a bit harder to find and more expensive.

The turbos support different power levels and boost pressures but if it is only to replace the original turbo with a new one, and not looking for any power gains then you can pick the cheapest turbo you find of the ones I mentioned.

Yogi said...

Hi jd, i have toyota sienta mpv, 2nrfke engine, 1.5L petrol, cvt transmission, non turbo, indonesian version. Already upgrade header 421, 1,75inch exhaust, porting polish, open filter, and piggyback by dastek unichip, power around 140hp crank power.

I want upgrade to turbo. I prefer max pressure 0.5 to 0.7bar for stock engine. Spool start from 2000 or 2500rpm. Max cranck power about 180hp, a bit worry with cvt trans.

Please advice which turbo should i choose, do i need twin scroll or ball bearing turbo?

Thanks in advance, sorry for bad english 🙏🏼

Yogi said...

Oh, one more, this cvt stay on 6.000rpm when WOT, so i need maks power on redline.
No need turbo spooling when low light cruising around 1000-2000 rpm.

Thanks in advance

JD said...

Hello Yogi, you don't need a twin scroll or ball bearing turbo. You need to look around if you can find one of the GT2052 Garrett turbos.

There are two options for the GT2052 turbo, one with 36.1 mm inducer and the other with a 36.8 mm inducer. Both turbos should work fine for your engine and spool between 2-3000rpm. But the 36.1 mm inducer GT2052 would work a bit better with low boost. You would need around 0.4 - 0.6 bar boost depending on the turbo you have with the CVT transmission to get to 180hp because those transmissions have around 10% transmission loss.

Thank you very much JD, what exhaust pipe size should i choose for max power and not to laggy in low rpm? Use free flow muffler or venturi type muffler?

JD said...

Hello Yogi, for your power it should be fine with a free flow muffler and 2 inch pipe. But if you can fit a 2.5 inch downpipe it would give you bit better spool up time. Downpipe is most important, after that the exhaust gases cool down and take less space so you can run smaller exhaust if you like.

Yogi said...

Great, thanks very much, very helpfull. How long 2,5 inch pipe? 30 inch enough? My header 30inch long now.

And after 2,5inch 30inch long, down to 2inch to muffler right? 🙏🏼

JD said...

Hello Yogi, yes 30 inch should be fine for the 2.5 inch downpipe. Then you can have the rest 2 inch pipe going to a free flow 2 inch muffler.

Yogi said...

Thanks you very much. I'll post here when the project complete 🙏🏼

Hello JD, and THANK YOU for everything you are doing for us!
I want to ask for your recommendation.
On my car, a smart roadster, I want to get 200hp from a 3 cylinder 0.8cdi engine block with enlarges bores, forged rods and pistons, lightened crankshaft and clutch. The gasoline cylinder head which will be mounted on that engine and it will be ported, and also the custom axle cam, both are waiting for my answer about turbo specs. Right now, the engine has 849cc, and it will have custom intake and exhaust, but all are connected and I have to take it step by step. Please tell me what turbo do you recommend, for achieving the 200hp goal, and if it's possible, I would preffer to have boost from lower rpm's.
Again, I want to say thank you for all the dedication and commitment you are taking in helping each and everyone one of us!

JD said...

Hello Bogdan A, thank you. If it's going to be a gasoline engine, then if you can get a really good tune on the engine so that it makes around 80-85hp without a turbo. Then you could get to 200hp with around 1.5 bar / 21 psi boost. Then the best turbo for low rpm boost you would be to use the GT1548 turbo.

However if you only can get to around 75hp without a turbo, then it would be better to go with the GT2052 turbo as it supports higher boost. And with 1.7 bar / 24 psi boost with the GT2052 turbo you can get to 200hp. However for faster spool and low rpm boost the GT1548 would be a better choice.

Thank you JD! I couldn't find any GT148 turbos, only GT1549, especially mounted on Nissan Almera with 110hp, and on Renault vans. Can you please confirm me if it is ok to use that model? Or better I should search for GT2052? Thank you!

JD said...

Hello Bogdan A, it looks like that GT1549 turbo use a 36.2mm compressor inducer so it's a bit smaller than the GT1548 turbo that have the larger 37.2mm compressor. I don't have all specs or a compressor map for the GT1549 turbo but I guess it's good for around 180-190hp.

You could probably still make around 200hp with the turbo but you would need to push a bit more boost to get there, and you would end up outside the compressor map. How much more boost is hard to say but probably around 1.7 bar / 24 psi..

The GT1549 turbo would still be a better option over the GT2052 turbo because you would have a 5mm smaller turbine housing so it will spool up faster.

Bogdan A said...

Thank you JD! I found GT1549, but I will keep looking for GT1548. Hope I will find one. Do you have ideea on what cars they were frequently fitted?

Bogdan A said...

I found this one.
https://www.ebay.co.uk/itm/323043687496
Can you please confirm if this is the right gt1548 one?
Thank you so much!

JD said...

Hello Bogdan A, there are too many different versions made of the GT15 turbo to know for sure. The GT1548 was made by Garrett and all others that came fitted to cars like the GT1549 turbos out there are some variation of that turbo. You could try and look for cars with bigger 2.2 liter engines that have high power. It's more likely they would use the bigger turbo compressor.

But you could ask the seller to measure the inlet of the turbo, and if it is 37.2mm then you would know it's the correct one.

However you could also get any GT1549 turbo and have a billet compressor wheel fitted to it. Like this one. Inducer Dia : 37.60mm Exducer Dia : 51.00 mm compressor wheel.

https://www.ebay.com/itm/Turbo-Billet-Compressor-Wheel-Garrett-GT15-GT25-37-6-51-0-mm-6-6-Balanced/292092624845

But that would also need some machining done to the turbo to make the bigger compressor wheel fit. However it would be a fast spooling +200hp turbo when done and could match the GT2052 in power.

Bogdan A said...

Thank you, JD! I will ask the seller to measure it, and if it's not the correct one, I will keep searching. I'm inclined to GT1548 because it is water&oil cooled, so it seems more reliable. If I won't find one, I will buy GT1549 and machine it.

Unknown said...

Hi JD - It's bmw e36 318tds-man here. ;) I bought the cheapest "1548" i could find. was a bargain at 65e plus freight.
It says 1549, which ofcourse confuses me now, and 705306-0001 144115M300 .

You specified a 1548 would be best, yet now i kindly ask you to verify and explain me the differences between the 1548 and this 1549S as it's called above in the list, and the pros and cons please.

Thanks a million

JD said...

Hello, the only real difference between the GT1549S and GT1548 would be the compressor and turbine housing design. The Garrett GT1548 use a common 4 bolt T25 flange. Some car makers instead used a 3 bolt flange to reduce cost or for ease of assembly. It could also have been they had limited space to mount the turbo and was forced to make changes.

You can measure the inducer on the turbo if it's a 37.2 mm compressor, then you would know it's the bigger 1548 compressor and good for 200hp. If however it's a smaller 36 mm compressor then you would probably lose a bit of airflow maybe 10-15hp. But it's really not that big of a deal unless you are looking to max out the turbo as the differences are so small.

Hi JD. Next issue i envision here. Do you have an idea what this 5M300 GT1549S turbo's oem wastegate is rated at? I am wondering to go with an external one, and if i have to mount an internal one, i'm wondering which rating to pick. I understand i need to go with the lowest pressure i'ld wish to have inside the engine. Yet i cannot seem to feel assured for now on what the basic pressure is, oem, in my m41 engine, as to compare this to the oem wastegate on the 1549S here.... Big thx...

Unknown said...

I now found that the oem 1544 wastegate is designed for a max of 1.36-1.44 bar, the 1549S is rated at max 1.4-1.6 bar.

Do i feel this correctly as in: i will need a wastegate with a bit of a higher rating, or you believe this one will work fine if a adjust the arm a bit so i opens less...? Thx

JD said...

Hello, on most wastegates the spring will open at the set rated pressure. You can adjust this a bit with the wastegate arm. But if you go with a 1 bar spring then to get to say 1.5 bar boost you would still need to bleed the air away because the spring might not hold that high boost on its own due to the exhaust pressure working against it.

Sometimes however in some cases the engine could still get to 1.5 bar boost with a weak wastegate, but then it could also mean the wastegate is actually pushed open a bit by the exhaust pressure. What happens then is you get a high peak in boost pressure but then it drops, and the higher you rev the engine the boost pressure starts to drop more due to the "leaking" wastegate.

As for now you can try the oem wastegate, and fit a boost controller and see how it works, if you start to feel like the boost is dropping too much at high rpm you can try a higher rated wastegate.

hello, i'm looking to add a turbo to my gasoline 1.2 16v engine, and i have in hands a GT1549S 454216-0003, my problem is that i did not find a map for this turbo, and that make me not sure if it will work or not, i only find maps for gt1548, could the 49 map be similar to gt1548? thank you

JD said...

Hello SimorRider, if you measure the inducer on the turbo it should be close to either a 36mm or 37.2 mm compressor. Either way the difference is very small and it should be fine to use on your 1.2 engine.

SimorRider said...

thanks for your reply, i measured it's 38mm and 0.35A/R, and on the compressor side i saw numbers 46 which i think is the wheel size, and M53 also which i think is TRIM, i think the map will be between a gt1544 and a gt1548, what you think JD?

JD said...

Hello SimorRider, that seems about right and that should mean you have the bigger GT1549 turbo so the compressor map should be almost identical to the GT1548 map.

SimorRider said...

thank you JD for your help :)

Jros said...

Hi, i have an opel frontera b 2.2 dti, and i find the actual car torque and power insufficient. Can i just up the maximum boost a little actung on the wastegate leverage without risking engine damage or ecu errors? What would you do? Thanks
