https://www.homemadeturbo.com/forum/...?topic=98291.0 here is some stock gsr pistons for sale for 30 with rods

Re: WTB LS pistons for boost
 

Stock is no bueno, this is a 400whp build. I need LS stuff anyhow

Re: WTB LS pistons for boost
 

theyll fit just fine... :S :1

Re: WTB LS pistons for boost
 

I still need something capable of 400hp

Re: WTB LS pistons for boost
 

Ur fine with 100% stock LS block at 400hp

Re: WTB LS pistons for boost
 

its been proven on here many times over

Re: WTB LS pistons for boost
 

Well that blows considering the engine was disassembled to check the sizes on everything. GSR pistons are the same size and use the same size wrist pin?

Re: WTB LS pistons for boost
 

GSR, LS, CTR, ITR and B16 they all fit ls block with ls rods just fine, I use ctr pistons on my Ls block with stock ls rod it fits perfect.

I think you need to continue shopping. you need a new turbo manifold first. check here www.tunertoys.com

look into craytex if you want to polish your port job. worth the time itll take

Re: WTB LS pistons for boost
 

Im not interested in polishing. Its gonna be a hog job for max flow. Thanks for the suggestions guys

Re: WTB LS pistons for boost
 

still, you need to smooth out the surface turbulence regardless. what good is massive ports if they choke flow?

Re: WTB LS pistons for boost
 

Are you talking intake or exhaust? I have been taught that 120 grit finish is sufficient on the intake side. A polished finish on the intake side will hinder fuel atomization due to being to smooth. How ever polished exhaust ports are good for flow.

Re: WTB LS pistons for boost
 

i assumed you meant exhaust side

Re: WTB LS pistons for boost
 

U dont need to port the LS head u need cams and valve springs

Re: WTB LS pistons for boost
 

Im going to be using cower turbo cams and kms valve train
