Stock GSR how much boost?

On the GSR what is the max boost that the stock pistons, roads, and cams can handle? My goal was 600hp but i decided to bring it down to between 400 and 500 with turbo. I just want to know the limits to help me figure out what I should change first and move on from there. Thanks for the help?

7 psi -- 9 psi

With a custom turbo using 9psi for boost, Will it get me to 400whp?

lol no.

with 10psi on a BIG turbo, you would be lucky to hit 300whp, and thats with very good tuning.

There was a car Tony @ Jotech tuned about a year ago, 83MM GSR motor with 10:1 compression, unported head, and an SC61 and it made 372 WHP at 9 psi.

gsr will handle around 300whp on a completey stock motor, maybe a thicker hg with a thicker hg you can make more power on stock parts, like jeff did 350whp at 11psi on 93 octane but of course he is a very good tuner.
