OK, so I learned that the piston sive is the same. The D16A6 has a CR of 9.1:1 and the ZC is 9.5:1 so the ZC hase a higher CR right? The zc pistons "should" make more hp... The rods however are shorter on the D16A6 which would promote more HP in the top end due to the shorter stroke... So correct me if I am wrong (engine builders) but a combo of the stock ZC pistons+the D16A6 rods will make for the most HP right?
