Ok, so I've been gathering parts for awhile now and i'm just about ready for my first j series build. I have a set of j32a2 heads minus cams (hey it was free) and a j35a4 long block. I've been doing a lot of reading and only have a few questions. I know that you can use acura pistons to clear the valves but then you get somewhere between 10.5 and 11.5 compression depending on which pistons you use. That's just a little high for me. I have read that j30a3 pistons can be used and have enough clearance and keep compression down around 9.8 Has anyone ever used them to know for sure?

 

im gonna be real, this is probably something better suited for honda-tech.com

dont believe we have many j-series guru's here.

also post on dallasimports.net tons of honda gear heads there. been with them since 05.
