my p2w clearance was .004 i didnt think it was that bad...its just barely out of service limits, mine didnt knock too bad, nothing more than any other forged piston...i had a friend with cp's in his sohc and you couldnt tell the difference.

A few thousandths is a few thousandths.

Clean bore D16 - a hard find, they are all 7+ years old now - take STD Vitaras as noted, but the ones with a little wear on the bore are the slappers. Frankly, the guys running Vitaras to be cool and only making 250-275 aren't going to have aproblem with this, but try running a big power D16 with piss ass piston-wall clearances and see how long it is before you run into problems.
