I got a rod knock and I'm in the process of rebuilding it. Its a b18b1 block that has been sleeved with crower rods and je pistons. I need to know how do I find out what size main bearings and rod bearings I need to buy. I know nothing about the block, the prrvious owner knows nothing, he just bought it ran it and gave it to me. I know its built for turbo and thats it. Help me how to get the right size bearings please.

 

Anyone? can I just take it to a machine shop and they tell me which ones I need?

 

You need a new crank or to grind the one you have. Machine shops are good at ruining cranks with crank taper and since it's a honda and spins backwards they can fudge that up to when machining and polishing.

Learn to use a micrometer and plastiguage as well, they are your new best friends
