I'm putting my B20VTEC back together and I need to know the ring gap for the B20. I'm using Arias 11.0:1 pistons, they don't have any specs for the ring gap though. I compared the sizes between them, stock top ring was .030 and the Arias was .025 the the 2nd ring for stock was .026 and the Arias was .016. Any suggestion on what to do?

 

BUMP

 

The machine shop had the pistons with them when they honed it. The Arias spec sheet states a .0035 piston to wall clearance. The rings with the pistons nonetheless are tighter clearances than stock, I just don't know what to have the gap at. BTW, it's at a stock 84mm.

 

just go off of the loose end of oem specs. you'll be good.

 

I called Arias today and talked to the guys out there. They told me between .015-.020 on the top rings and .012-.015 on the 2nd ring. I checked all of the rings today and my top rings are all between .017-.018 and the 2nd ring is .012-.013. Everything seems cool now, not too much filing to do.
