Garrett GT15 – GT1548 – 200 HP

Garrett GT15 Turbocharger GT1548 picture Largest 200 HP Garrett Turbo Honeywell 450x432

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.

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.

Garrett GT15 Turbocharger GT1549S Rebuild Kit Worn Turbo Compressor Wheel Turbine Shaft Rotor Honeywell 497x374

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

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.

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

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.

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

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.

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.

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

JDOctober 15, 2016 at 12:30 AM
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.

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.

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

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.

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.

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.

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.

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

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

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.

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.

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

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.

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.

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..

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??

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.

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.

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.

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.

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.

Thanks again for your help

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.

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?

JDJanuary 16, 2019 at 1:58 AM
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.

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 .

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.

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 ?

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.

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!

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.

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..

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.

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.

Please advise a suitable garrett turbo same like CT15B?

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.

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.

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.

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.

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.

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.

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...

JDMay 17, 2020 at 6:20 AM
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.

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

JDJune 30, 2020 at 6:33 AM
Hello Jros, the Opel Frontera 2.2 dti engine should have a 2.5 bar maps sensor fitted stock. This would mean the maximum amount of pressure the ECU can read is 1.5 bar boost. Now you should be able to raise the boost pressure a little bit on the wastegate but there is a chance that if you go too high, then the ECU will throw an error code and the car will go into limp home mode.

The engine does also have a Boost Pressure Control valve fitted, this valve is what keeps the boost from going too high and is controlled by the ECU.

Now on some older cars you could disconnect the boost control valve and this would allow you to run higher boost, however on new cars they will throw an error code if the valve is missing.

I would highly recommend you get a boost gauge fitted, and then once you know the stock boost pressure and get a base line boost reading you can slowly increase the boost pressure by 0.1-0.2 bar (only a few turns on the wastegate arm will do and then check boost). That alone should give you around 20hp extra and that should be safe, as long as you stay under 1.5 bar boost that is. If nothing happens then there is a possibility the boost control valve is adjusting down the boost and if that's the case you could try and disconnect the valve. But again there is a possibility you could get a fault code doing that.

JDJuly 1, 2020 at 3:23 AM
Hello Jros, in most cases the ECU should take care of the extra boost and compensate fueling as long as you stay within what the map sensor can read, in your case 1.5 bar. It's when you start to go over this when you risk running lean. This is however not that big of a deal on Diesel engines as they can handle running lean, you just don't make any more power due to the lack of extra fuel needed to make more power.

JDJuly 3, 2020 at 12:24 AM
Hello Jros, sounds like the ECU / boost control valve is adjusting down the boost pressure to 1.1 bar. You could try and disconnect the boost lines going to the boost control valve and fit a manual boost controller instead or disconnect the connector to the valve if that won't throw fault codes.

A quick fix is to try and bleed some of the boost away with a simple small 5-6mm t-piece on the line. Spool times won't be as good as with a proper boost controller and you need to be careful not to bleed too much air away, because the more you bleed away less pressure is acting against the wastegate spring and the higher the boost you get.

But for testing to see if the boost pressure will stay on high boost it should be fine.

Hello Lukas, if you search for "GT1749 repair kit" it should contain all the screws and o-rings needed. There are several kits on amazon, aliexpress, ebay etc.. The parts in these kits are probably made in china but so are most OEM parts anyway, and really there should not be any difference in quality if you buy from a bigger known seller.

The wastegate actuator on the GT1749 comes in a few different versions depending on the model of the car. All should fit a GT1749 turbo and function just the same but some cars like Audi A3 etc have a version with a sensor fitted to the top of the actuator, so you need to make sure you get the right one for your car if that's the case. However you would still be able to use an actuator with a sensor fitted on any car, you would simply not use the sensor in that case. These wastegates can also be found on the same sites already listed.

Hello Northpole, before changing any turbo first try and see if you can get the boost pressure up to around 1.5 bar / 21 psi. And see if you still get black smoke.

It would be hard to find a direct replacement turbo because the turbine housing on the Garrett T15 used by the Vauxhall 2.0 dti engine is a 3 bolt flange.

The Garrett 751479-5003 GT17 turbocharger do use a 3 bolt flange, however I'm not sure it is the same pattern and would fit. And also they are almost the same size anyways so it would only be a very small increase in power with the GT17 fitted.

If you can't get enough airflow from the stock turbo with higher boost then the best option would be to go with a GT20 size turbo instead, even though it's not a direct replacement. The bigger turbine housing will also hurt spool a bit but you should also be able to get more top end power all the way up to 5000rpm.

Hello Andy, most of the time rebuild kits are sold without the turbine and compressor wheel. But you can still find them sold on ebay or aliexpress to name a few. If you really need a new turbine wheel and compressor wheel for your turbo, you might want to save some time and get the complete balanced GT1549s CHRA instead, because you are not saving that much more money, if you need to buy a repair kit and turbine / compressor wheel from separate sellers anyway.

Hello, I would recommend you look at a hybrid turbo like the GTB17 turbo it would do around 200hp. Above that and you should look at something bigger like the GTB2260 hybrid turbo. However because the stock MG ZR engine needs so much boost to reach 200hp you are looking at around 2.4bar / 33psi boost to get there. So I would highly recommend you do some cylinder head porting first. That way you could probably reach 200hp with only around 1.5bar / 22psi boost. And if want to go higher the GT2260 turbo you could get you around 240hp with 2bar / 29psi boost.
