This question is just out of pure curiosity I have no intentions of doing this I'm trying to fully grasp the concept. b16a vs b16b, the A has a r/s of 1:74:1 the B has something like 1:86:1. how significant would that difference be at say 9500 rpms,10k rpms and 10.5 K as far as cylinder wall side loadings? or does it not matter at all in those rpm ranges? at what point repectivley would the B16a's r/s ratio be putting more stress on the cylinder walls?
