**** a B18C, do we to get into why the B16A is better? I say go with the b18B turbo. I know guys running 12's on stock internals with a decent turbo set-up. The B18C will give you more power initially but a B18B would put you that much closer to a turbo kit. Hell, is'nt there a guy on here with a B18B1 witha JRSC? I think his car is pretty quick and has good daily drivability. Trust me, turbos are not the best for stop and go traffic every day. I would hate to have to drive my coupe everyday in traffic.
