Since there's rust in the cylinders, start out ismply honing them to see how deep the rust goes. If it's too deep for a simple hone, you'll obviously need to bore it a bit. Then the bore will be too big for the CTR pistons, unfortunately.

Otherwise, you'll be looking at a static CR of about 11.5:1 with everything else fully stock.

- Thu Aug 26, 2010 12:37 am #210591 I lied. Just redid the calculations with the CTR pistons (I clicked B16A instead of B16B).

13.3:1 with a conflicting picton compression height. You'd have to use shorter rods, maybe LS rods?
