Is there a way I can get compression up to 12:1 with the stock b16 81mm bore? Or do I have to raise the displacement?

 

Install CTR pistons, a smaller headgasket and mill the head .030

 

ctr pistons .25 over and 1 layer headgasket will put you close

 

Yep, that will do it. when you mill the head, just make sure you time your cams properly if it has some crazy duration.. You can make the exhaust and intake valves hit due to the overlap.... seen it happen.. Just a friendly reminder
