What should my c/r be with my setup? Just wondering if I am close to the 13.0:1 danger zone?
Setup:
B16a
81mm bore
JE 12.5.1 pistons
Head milled .002"
Also another question how much can a B16 block be bored out safely b/c I am thinking about going 85mm? Any inputs will be appreciated!

without resleeving, 81.5 is as large as you can safely go when boosting, and 82mm if you plan on staying all motor and wont be stressing the sleeves excessively with high rpms.

So with a sleeved block would it be safe to go as much as 84 or 85mm (@1.78L I think)? This is a street car and I want the motor to last for some time (50k) in between rebuilds?
