what's the ideal compression ratio to be able maximize potential ng SK2 st2 cams on a JDM b18c5 motor (11:1 compression)?
if you were to bump up the compression, thin head gasket(like spoon, mugen) and flat faced valves or b16b pistons? TIA.

 

bump!

 

11.5-11.7 + will do well

 

thanks! more inputs about flat faced valves. how much will it bump my compression?

 

.4
