So I have a B18A1 Block and a B20 Head. Im looking to build this motor from nothing to make it a motor to be sprayed and turboed. I have never built a motor before, or atleast this in depth. I am in desperate need of advice and guidance. Do i Bore the pistons out or leave them stock? Do I have the head ported polished and everything replaced in it or just replace the cam gears? I have all the stock parts but i want to make sure that the motor with last through some H*llacious times. Any advice is better than no advice.
