Josh why don't you go for some forged pistons stock bore for an LS motor keeping your comp. ratio in the 9:1ish area? That way when you do boost the bitch again you will not have to worry about broken ringlands etc. Trust me I've seen too many stock LS pistons go due to over boosting and bad tunes. I mean, you CAN use the stock LS internals or even some GSR pistons, but keep in mind their stock. Your power limitations are going to have to be held back :-\

bwahaha, that's it, holy ---- i'm gonna own you with my b16 :D what the ---- is your question? you say you're not putting forged in, so then i guess pr4's are your only choice bitch, unless you'd rather run some higher comp. p30's, then you might get a few more pony's and have a chance, ass hat. btw, you get your goody bag yet? give me one of those short shifters bitch.
