I'm running a GT30 on a built H22. I'd like to get the same power with lower boost pressure and also be able to develop more hp if I decide to.
I currently develop around 435 whp @ around 17 psi using E85, with the GT30. Would I be likely to get the the same whp @ 15 psi or so, with the GT35?

 

it could be posible since its a 2.2, i have a gt35r on 84X87 gsr and made 460 on 17psi, are you planing on making more power if not just keep the gt30r

 

Yes, thats what should happen. You should make more hp on a lower psi due to the turbo flowing a higher lb/hr at the same psi versus the smaller turbo. If your looking into the GT35r, I would also take a look at the BW T3 S362ett.

 

Thanks, that's my understanding. I want to make around 500 whp.
With 1000cc injectors and E85, I'm already using E85 instead of methanol/H2O in my methanol injection system for added capacity. Guess I'll be using 1600cc injectors so I can eliminate the additional E85 injection.
