(Thread Starter) | Not Ranked : 0 score So im currently in the process of building the engine for my speed6. Currently have brand new 88mm supertech pistons and a block waiting to be bored as soon as i get with pwc sorted. Im wondering what PWC you guys used for 4032 alloy pistons? I called supertech today and was told 0.0027 minimum for my target boost level (20 - 25 psi ... plannin on getting a bnr s4) but the spec sheet indicates 0.0035 with no indication of target boost levels?? Im inclined to believe in the 0.0027 since i read about lots of people running 0.0035 for 2618 alloy pistons. That said, this dosent make sense to me since the sheet indicates a bigger pwc then what was recommended to me on the phone ...
