Is this compression calculation correct?
I went to the C-speedracing.com website and used their compression calculator. This is what it gave me.
USDM B18B block (81.50 mm bore) B17A head Stock 3-layer head gasket Pistons: p73-A0 (USDM ITR) - 11.8 CR p73-00 (JDM ITR) - 12.4 CR pct (CTR) - 13.2 CR Are those correct? I just want to make sure before I go get a set of USDM ITR pistons for my LS/VTEC. What is needed to be done to the rods to make the pistons fit on Eagle B18B rods? |

Ok, I wa just reading thier LS/VTEC buildup and it says that they used the B17A head and the P73 pistons and that gave them a 10.9 CR. Whats going on here?
