Wiseco...or through Larry (Endyn) do make 81.5mm pistons. I think the overbore pistons prices are the same. Can get the Endyn through Mike K for $530.
Update on the block: It was only one cyclinder that was worn to that degree. I think they were able to save it though. So time to build the motor up.
The mic on the crankshaft indicated stock specs. What bearings should I ask for when I call up Acura? Do I just ask for stock?
Thanks again for all the replys.
