just wanna know if there is any way to get more effeciency out of a t3 turbo. I have a t3 with a .60 on the compressor side and it peaks at around 5-6 K. It pulls really hard until then but then just stops. Is there any other way other than changing the turbo or replacing the compressor side with a t4? Any help would be great!

 

What are the other details of your set-up? Intercooler size, boost, what engine? You could port out the turbo (smooth it out and enlarge the housings a bit) probably good for a little more flow. It is most likely flowing enough air, unless boost is REALLY high (about 22+psi) you're probably just pushing hot air into the engine, so it's losing efficiency. you could insulate your charge pipes, get a bigger intercooler, add water/alcohol/propane injection. if it is running out of air, then you are screwed and probably need a bigger turbo just my thoughts.

 

I'm running it on an h22a1, using an intercooler core from an audi 5000, an 8:1 fmu, an inline fuel pump and stock internals and stock 330 injectors. I'm boosting between 7-10 psi depending on the what gear I'm in, but over all, it runs outta steam at around 5-6k and really flattens out, but in the lower rev range, it really pulls hard and there is virtually no lag!

 

maybe you should consider changing the turbine section..Your compressor is 60 trim but what's the a/r on the turbine..I think knowing that would help determine why you are running out of steam..and for the guy w/the h22a1, that's why you are running out of steam..You can change the a/r to .63 and get plenty more top end and not have that much lag...I would assume you have a .48 a/r turbine. I have a t3/t4e but my a/r on the turbine is .48..I may not change simply because I have a h23 and my redline is 6500 anyway and I have no intentions on raising it.

 

maybe you should get bigger injectors.

 

IMHO...a full T3 is way too small for a H22.

 

Yah, I'm pretty sure that it's simply running out of steam because I have an h22a1, so that's why I'm asking about different ways that I can retain both the comperssor and turbinie housing. It's cramped in there as it is, and I just want to know if I can change the turbine blades or compressor blades. The turbo is out of a Merkur so I think it's a .48. All I know is that it spools incredibly fast but dies early. I don't think bigger injectors would do anything cuz I'm getting all the fuel I need, but like I said, is it possible to change out the turbine wheel or something along those lines?

 

I'm not so sure you can do that. I think you would have to change the entire turbine section and not just the wheel. I'm not sure though, you're out of my rhelm of knowledge..I'm still learning myself..Send an IM to Viren (b18bturbo). I think he could answer that one fairly quickly for you. I know you can fit a .63 a/r turbine w 60 trim compressor in a prelude..It depends on the manifold you have. But it is possible
