    What piston to use for rec ski less than 20lb boost.

    Would standard bore and compression be fine for less than 20lb of boost. Also is anyone having pistons coated or cyrogenicly treated? I know someone who does it they say I should do my rods pistons and crankshaft. I just want to run 93 pump gas. CP or RIVA piston?

    CP Riva are now CP anyway, MTC is no longer making Rivas pistons but better deals can be found buying CP and Carrillo rods too

    I would stick with stock compression not unless u won't to run 100 octane or avgas. Also the cp's like big john mentioned are great. The je pistons are good to. I think u can get the wiseco pistons cheaper of all the ones mentioned
