Just for you single cam slammers out there. The limited production Natural Gas civics (civic GX) 97-9x? sold in the US came equipped with 12.5:1 compression forged pistons. If you could get a hold of a block/engine from one of these. The pistons will fit into a d16y8 from what the Honda techs tell me.

-list price is 36.61/piston.

 

yeah they should fit most d16s i believe, but im not sure about the valve clearance.
