and id use jdm b16 pistons (p30) for higher then itr ..or use pr3 which is still higher comp..the p30 pistons with b16 head yield 11.6 dependin on if the heads shaved, usin oem HG etc but roughly in that area..and is good for daily driving on 93octane...i definitely dont recommend going cheap..but i dont recommend using forged internals either..stock oem internals will be strong enough for an all motor app..the only way imo ud need forged is if u plan on high comp + a lot of nos..then ull need better internals and maybe even sleeves...which is way to much money in either route...so id say go the cheapest route for urself..if u can get a gsr shortblock for say 600..or u could get an ls for ? 300..then have to rebuild it..plus use vtec water/oil pump then the gsr would be better/easier/cheaper.. so just figure out your budget and what you HAVE to work with ..
