I am getting ready to turbo my GSR this spring and want to know if anybody knows how much PSI you can run on a stock block etc. with a good tune?

I will be running some 450cc injoctors but thats about it. everything else wil be stock so with a good tune what do you think i will be able to hit PSI/whp wise? I have heard from some 12psi/310wp (ish)

any help/info woul be awsome

thanks

depending on which turbo ( inlet outlet ) you will be running, but aroung 8-10 would be great

 

boost pressure is irrelevant.

stock map sensor can read up to 11psi. stock motor can handle 10 million PSI, its horsepower that matters.

 

get a map sensor, ems, and a good tuner. then just see where it stops making power.

cool cool thanks for the info so far.

if it matters i will be running a t3/t4 63 trim

 

.63 is probably the aspect ratio on the turbine side...

agreed, i shoot for around 300whp to 320 if you want it to last a long time, just get a good tune, the tune is everything....

and i'm thinking that your talking about a t3/t4 63a/r probably a 57 trim

 

lol...

63 trim... .63 a/r

it deffinently should be a t3/t4 57 trim turbo with the .63 a/r
