This is what im looking for, a setup with minimal lag (who isnt) ,has to fit my revhard manifold (the turbo i have now is a T3/T4),and wont fall off in the top end on my gsr.. I have a rev hard manifold downpipe ect and the turbo has to be 5bolt..im only running 5.5psi now. my car will be tuned to 7or8psi with uberdata. i dont intend on pushing more than 300hp to the crank so say max 280whp. and my turbo works fine its a t3/t4 it reaches 5.5psi at around 3500rpms(starts reaching boost at about 3000) and would want better spool up than that if possible... i was thinking about a 50trim 63a/r T3/T4...? to be honest my knowledge on turbo is limited but im learning. im going to buy a 5bolt turbo ,want a better one than i have and of course sell my old one because its a 4bolt and wont work with the downpipe and retain ac. Ive decided already not to swap the housings.. id like to hear any input thanks

anyone?

You should contact TheShodan and have him a spec a turbo for you. He is very knowledgable and has a turbod gsr himself.

the .60 compressor 50 trim / .63 turbine will be good for 450 hp. You should be fully spooled by 4400 or lower with only 8 psi. It will pull up to and a little over redline.

Since you only want 280whp and fast spool, I would go with the GT28RS ball bearing turbo. It will handle about 300whp max and will spool quickly.

 

i already have everything for a t3 flanged turbo has to be based on that turbo. i dont think that turbo will fit my revhard manifold

 

.

 

the gt28rs will fit it. It is probably one of hte best turbos you could get that spools quick and does a damn good job of making power.

 

i forgot that was the disco potato turbo... i cant afford that thing.. lol nice though

 

what size trim turbo do you have now?

I have a t3/t4 57 trim with .60/.63 ar's. I hit 10psi by 4700rpms, I decided to switch the compressor housing with a .48 for faster spool, I haven't tried it yet, but it was a cheap alternative to buying a new turbo. SHould still have great top end and quicker spool.

Just a fyi, I have a Precision turbo 57 trim .48 compressor housing for sale. 5-bolt downpipe style.

Do you not mean a .48 TURBINE side? Not compressor.

 

i have a t3/t4 with a .63 but i dont know what trim it is i bought it turboed....

 

do i really need a t3/t4 or could i use a smaller t3 turbo but then with a stock motor isnt the cylinder pressures to high when boosting on low rpms on a stock internal gsr motor...?
