anyone boost a stock gsr w/ p30 pistons??? Just curious waht kinda power that would make as well as reliability. Im running a 50 trim turbo currently. Not sure if p30 or p73 would be better!!

i have an lsvtec with 81.5 pr3 pistons, b16 head, and a .074" thick cometic head gasket. i believe my compression is about 10.26:1, and i have pushed 9psi so far on a chinese 50trim t3/t40e.

hp wise i have no idea, but i guess about 270-ish whp.

i had a gsr with p30 pistons, mini ram manifold and a t3t04e 60 trim i made 305 at 7 psi. went 12.0 it was my daily driver to. just sold the motor. still runs strong!

damn those are some impressive numbers. I really do think Im gonna give that set up a shot...anymore dyno numbers on that set up??

just buy a set of forged pistons and save yourself time and money.

tru, I did find a set of wiseco 11.5 pistons for 350 obo....however I found p30 pistons with rings for like 120.

it trully depends on how capable your tuner is. find someone to tune the car, ask them questions.

bustdgst

true...but I also wanted to get some opinions from someone who has this set up already

miller

how much power do you want to make?

bustdgst

around 280 doesnt sound too bad

i put a gm 2 bar map on mine will be turning it up to 12 psi. so i will let you know if it holds.

sounds good
