[B16A CRX]

Can anyone plz tell me what the compression would be of a B16A with CTR pistons. Ive been researching for a while and I get things like 10:8:1 and 11:9:1. I need to know for sure. Thanks in advance

Sorry dude, I don't know what happened... I think it's a pretty reliable calculator, but I guess there's no way to tell for sure. You said you'd be in the high 11:1 range, that should be fine, as always just tune it well.

that means high in close to 12 to 1 or 11to 1
