Hey, I am rebuilding my block and I'm haveing it boared .020 over. I stopped in at the machine shop today with the pistons which are low compression cast pistons. The shop wanted to do the final hone with the pistons to get propetr clearance. But They dont know what clearance. So I started searching and cant find anything on it. I found with forged pistons you can have a tighter fit than with cast. So should I go with stock piston to wall clearance? if so what is it?? Thanks for the help!
Its a d16a6 bottom end.

 

what motor? :P

 

eh if your going Forced induction I'd go with .0022 and NA .0020

 

my wisecos suggested +.0030 (8.5:1) measure 1.3" down from last ring groove, perpendicular to wrist pin to get piston dia.

 

My y8 called for like a .003, but for turbo's sake we went with .004. Trusted the mechanic on that one.
