i dont think there'd be much diff. between the ITR and the P72 piston, well, comp. wise if your gonna open up the engine might as well do like B16 pistons(still runs good pump gas) if your gonna do this on a budget and try to keep it reliable dont even touch the bottom end lots of ppl make good power on stock GSR bottom just work on how your engine(tthead) flows thats how u make power u cant just up the comp.
Get like Stage 1 cams(PRO1's make decent power), good INT. manifold, T. Body, good headers, (165-175hp) and a good ass tune......thts my
