I do agree that the B18A/B has the best compression for forced induction because it is low. But they are a lot more suited to a turbo is what I was trying to get at. A supercharger is limited by how much boost it can run whereas a turbo has the possibility of running much higher boost levels. From almost every dyno I've seen the B18b doesn't take real well to a supercharger. Most of the time only making 20-30 horsepower to the wheels. I do believe that the B18b is a very capable engine and would be my second choice as a swap into a civic, right behind the H22a. Also a B18b with a supercharger in a 92 civic would not be a car I would want to race especially if it had the 8lb pulley upgrade.
