I've been re-reading the article on rod ratios and stroke and everything else in it. MD told me that a 1.75 rod ratio is considered ideal. Stock, my B18C1 has a rod ratio of 1.58, agreed? Okay, to get close to 1.75 I worked out that if I use 134mm rods (I was told these were CTR size rods) and the crank form a B16A/B then I get a rod ratio of 1.73, pretty darn close if you ask me. My question is this: By using a smaller stroke, and shorter rods, won't I be adversely affecting the displacement? I don't know the actual terms to use here, but by using this setup, the pistons will not reach to the highest possible useable point of the cylinder, right? I'm basically creating a B16 inside a B18 block, I want that displacement back! What am I doing wrong?
