Anyone run this turbo, making good power? Looking for opinions, setups, etc. I find it odd how it rates at 750hp with an 88mm wheel compared to T67 rated at 800hp. Also, how is the spool time and general charecteristics with the turbo?

Geoff at Full Race uses the bb unit on his civic and has made ~770fwhp. In my opinion you wont find a better turbo capable of ~70lb/min.

Brian Robards has it on his Supra.

Search for the member Latteboost; you should find a thread started by him with a dyno of that turbo.

He has a t04r.com page but it is down.

Read through the entire post. Looking for more opinions/users.

The 4088 has a 88mm exducer and 65.5 mm inducer....... so it is smaller than a 67!!

What about the dimensions of the exducer of the 67? Also the turbine dimensions?

Some of the honda community uses the 4088, i have seen them make over 800whp on them.

My 4202 on my Supra is great as far as spool, better than my old 76.

Any supra pushing 800whp with a 4088? So a 4088 is actually a "size" smaller than a regular T67 eh? The name is so deceiving.

No its not. The inducer is 63.5 vs the 67 but the exducer is 88 for the GT4088 and the exducer is 84 for the T-67. The turbine is also bigger on the GT4088. 77mm vs 74.2mm. You also get 4 different a/r housing options with the GT4088 and oil and water cooling options. IMO this is a great turbo for a car looking to make around 700-750 wheel.

Is anyone using the non-R 4088? The 54trim 88mm compressor that comes in the "non-R" turbo looks a bit better infact. Any data on that? Where are you guys buying it from?

Looking to get one in a non-div tang housing if possible.

The bush bearing GT4088 is different from the 88R in other respects that the bearing system .

Firstly its compressor is an 88mm 54 trim wheel with 6 full and 6 splitter blades of the GT family .

Its turbine is 77mm 84 trim rather than the 88R's 77mm 78 trim .

The compressor in the 88R is from a different family (C117) and uses 7 full and 7 splitter blades .


It sounds like the original development GT4088R used the same wheels and trims as the plain bearing GT4088 , some of these escaped captivity and a certain vendor got a boot in the blurter over it .

There seems to be some confusion in terms in the US and this revolves around the practise of refering to a compressor wheel by its inducer size . Garrett dosen't do this for the simple reason that many compressors can have the same or similar inducer diametre but nothing else in comon including performance . So the GT4088R's compressor would be 88mm 52 trim C117 . I think the TO4R wheel is 84mm 63 trim BCI 8D .

I think that you would have to do alot to the engine to get it to push 700 whp with this turbo (cams, valve spring & retainers, raised rev limiter). On a stock longblock with the largest turbine housing currently available (1.06 A/R) we couldn't get the turbo to hold more than 27 psi to redline. I think that the turbine will begin to choke before you get to 700 whp, but I could be wrong (wouldnt be the first time). A stiffer WG spring will probably help hold higher boost, but I think we are really pushing the limits of this turbo currently.

discopotato03- great info thanks. I guess I might have to get a GT4088R in that case..the only problem is my manifold is undivided, so I'm not sure if the 4088R is offered wtih a undivided housing.

Latteboost- Isn't full race making ~800whp on this turbo? In theory our cars should be able to make the same power, just at a lower RPM. Of course I'm sure that is pushing it to the edge, so thats why I thought 700-750whp is a safe conservative power output of the turbo on a mild-setup for our cars.
