I was also doing some playing around with certain rods/pistons etc...
B18a block, B18c1 head, CTR pistons, B16 rods. Would you have to mod the rods at all, like move the pin up/down? If not wouldn't this be a pretty good combo being as it would have like an 11:1 c/r, and should have a great R/S like the B16.
*shrug* I was bored at work. Who knows.
