I am going to to fully build one of these engines up in a year or so, but I have enough money to do either of these swaps now. Since the difference between the motors is around $700, I would like to know what you guys would do. If you think the B16, what would you spend the money on? I am keeping the motor NA for sure. I already factored in matinence items. I drive a '93 civic hatch btw. Some people say you need torque for auto-x, but others say you need revs. Is the B18's extra torque worth the $$$ or should I rev it w/ the superior r/s ratio of the B16? What would have more potential for the price. I'm just looking for opinions, thanks.
