I'm currently in the process of building an NA B18A and i'm looking for a good set of pistons to put into it to give it at least a 10.5:1 compression ratio. I've been thinking about either the B16A pistons or B18C pistons. Not sure if these will work, tis why i am posting. I already bought cams and a skunk2 intake manifold and may be buying a lightened crank. Any thoughts on piston selection?
