ok i have a jdm b16 and i wanted to change the pistons to ctr, but people are saying running thse pistons will yeild crazy compression ratios, but i have a compression calculator and it doesnt nearly come close to what people are saying. they say run itr pistons, but what i dont understand is that if the jdm ctr angine itself has a 10:8:1 compression and the itr has a 11:0:1 compression, why would the ctr pistons yeild higher than the itr pistons?
