Well, i posted this post on the integra forum but there wasnt any help watsoever so i thought i'd post it here. I opened up my engine today to replace the piston ring due to leaks on mostly all the cylinder and it would not pass smog. I am replaceing my piston rings, clutch and possibly valves. Since the engine is already out, i would like to raise my compression to about 11:1 ( since Im planing on adding Sunk 2 IM and stage 1 cams later on after the smog). WOULD RAISING THE COMPRESSION THAT HIGH AFFECT SMOG? I think that it wont but i just want to verify it

 

wow.. i never knew that. Can anyone else verify this. I will probably go with b16 pistons to raise it to about 11:1

 

b16a pistons will raise your CR to about 11.5:1
if you want 11.0 or close to it, then your best bet is US ITR pistons.
