What I'm trying to figure out is will ITR pistons alone raise my compression or would I need the whole bottom rotating assembly?
dont waste money on porting and polishing.and getting rid of the stock intakemanifold is a good start on a Gsr..if your going to put ITR pistons in your gsr upgrade the cams also to Itr cams to work with the higher compression
