No worries bud. afaik it does work but i've never done it. The b16b block is the same as b18c I think just with different internals, so you would need b18 crank, rods and pistons. I could be wrong though. As it goes... I have a balanced b18 crank, eagle rods and acl race bearings for sale. Less than 2k miles on them if your interested?
