The Garrett GT2560R turbocharger is also found on some engines from stock like the Nissan SR20DET engine, that's in the newer Nissan 200sx S14 Silvia models or 240sx.
The Garrett GT2560R turbocharger is also a popular choise for people who are looking for an turbo upgrade. Also there are many aftermarket turbocharger kits that have this turbo. This turbocharger can give you up to 330 HP and works well if you are looking for 200 HP. The engine size recommended for this turbo is between 1600cc to 2500cc.

this is not a journal bearing turbo
ReplyDeleteThank you for pointing that out Patrick, the post have now been corrected.
ReplyDeleteSo do I have to use the water hookup on the turbo or can I run straight oil
ReplyDeleteHi Caleb, you can run the turbocharger without water but because this turbo is a GT25 ball bearing turbocharger it also means there is going to be less oil going to the turbo for cooling vs a journal bearing turbocharger. If you need to only run oil it's very important that you make sure to do the proper turbo cool down period before you shut the engine off.
ReplyDeleteThis means easy driving (no boosting) the last few mils or you might want to idle for around 5min before shutting down but it depends on how hard the turbo and engine have been used.
Garrett however says that "Water-cooling of the turbocharger's center housing has essentially eliminated the need for turbo timers or extended idling periods.".
So even though it's not necessary to run water, if you can get some water to the turbo it would really help with the cool down especially when running a ball bearing turbocharger.
Ways to keep the turbocharger cooler is to try and get some fresh air flow going to it and absolutely not using a turbo blanket because that will trap the heat much longer and you would fry the oil / turbo bearings.
Would this be a good upgrade for the 1.4 multi air turbo dodge dart? The dart has both oil and coolant lines for the stock garrett turbo already. The stock turbo runs higher boost 20psi. Would i be able to run the same with this turbo? Any idea if it would be a direct replacement or would their have to have manifold modifications? Thanks
ReplyDeleteHi Brandon, I would say that running 7 psi with the GT2560r would give you more power than you currently have and with 20 psi boost around 300hp. If it's the Garrett GT1446 turbo that's fitted to your engine then they share the same T25 flange and the oil and water lines should also fit. But it could be a problem with enough space for the bigger turbo so you might need a manifold also.
ReplyDeletehow much GT2560R price right now sir?
ReplyDeleteHello Duke, the retail price for a genuine Garrett GT2860R turbocharger is around 1000 dollars, but you can find them for around 800 dollars + shipping. Garrett changed the part number, the old part number was 466541-5001S and the new part number is now 836023-5003S but it is the same GT2560R turbocharger.
ReplyDeleteHowever if you want so save some money there are chinese made GT25 turbochargers for around 200 Dollars. The only downside is they are not Dual Ball Bearing like the Garrett GT2560R. But other than that in recent years these cheap turbochargers are usually of good quality, but it is still recommended to do a balancing before use.
Hi am no expert on sizing turbos but wanted to know roughly when the gt2560r would boost on a 2.2 5cyl? I know it is at the high end of the spectrum for engine sizes and worry it will choke up fast. I will be controlling the wg via n75 thanks
ReplyDeleteHello, actually with a good setup you should have full boost around 3500rpm with the GT2560R on the 2.2 liter engine, expect the turbo to start around 3000rpm and keep going to around 6000rpm. With a good tune you might be able to extend the powerband a bit more.
ReplyDeleteBut if it's more top end power you are after then you could go with the GT2860RS turbo instead, however that turbo also won't hit full boost until around 4000rpm but it will instead keep going to 7000rpm.
What would be the max hp you could make with a garrett 2560r?
ReplyDeleteWhat would be the max hp you could make with a garrett 2560 r
ReplyDeleteHello, with a good tune and ecu if you can get the air fuel ratio just right at peak power you could probably push the GT2560R turbo to 340hp. However the 62 Trim GT2860R turbo would be a better and safer option if you want a bit more power and still have similar spool, because you would not be pushing the limits with that setup.
ReplyDeleteI'm looking for an upgrade from the TB25 on my diesel engine but cannot find any information on its specifications for that turbo so I have nothing to compare it too. Can you direct me to any specs for the TB25 or offer a suggestion of a suitable turbo upgrade. Thanks very much
ReplyDeleteHello Stallion442, there's not much info to go on and there seems to be a few different size compressor wheels for the Garrett TB25 turbo. From what I can tell the stock TB25 inducer should be around 38-39mm.
ReplyDeleteFor a non-variable vane upgrade you should probably look at the bigger 60 trim GT2560R with 46.5mm inducer or the 62 trim GT2860R with 47.2mm inducer. Anything smaller would not be much of an upgrade.
A better upgrade turbo for you would be the variable vane type GTB25 turbo. These should spool up a lot better on the Diesel and also comes with a slightly bigger 50mm inducer. However they are also quite expensive to buy new.
Great, that's far more advice than I have gotten anywhere else so I really appreciate your answer. This is for a TD27 2.7 diesel so I could look at something like the variable vane turbo from the ZD30 but my question is how would it be controlled? Do they need to talk to an ECU to determine the correct vane position?
DeleteHello Stallion442, the easiest route would be if you get the ZD30 turbo that use engine vaccum to control the vanes, that way you don't need need to worry about vane position.
ReplyDeleteIn case of bmw GTB25 turbos that use the VNT Actuators or Electric Wastegate Actuators, you would need an ECU or PWM control (under the cover it's really only an electric motor that drive some gears to position the vanes).
There are people making Standalone VNT controllers out there also..

Awesome yes I have been doing some research myself and it certainly looks very achievable. I see the turbine inlet flange on the GT2052V is different, it's a 3 bolt triangle style but I want to make a better manifold anyway so that's fine. Is there a compressor map anywhere for the gt2052v? Thanks again for the awesome input.
DeleteHello Stallion442, like with most hybrid and variable vane type turbos there's no official Garrett GT2052V compressor maps around, but you can have a look at the non-variable vane type GT2052 compressor map instead.
ReplyDeleteAhh yes that explains the lack of maps. Thankyou.
DeleteWould the gt2860r 5 bolt flange bolt to the Flyin Miata upper down pipe? I. urgently have the gt2554r and that 5 bolt pattern works.
ReplyDeleteHello, the GT2860r turbo flange 5 bolt pattern is close if you flip the flange. But even then you only might get 3 bolts to go in. So you can only really use it for mockup and testing.
