my recommendation...superchargers are not all that great on our non-vtec motors. Sure they're great for reliability and daily driving, but if its peak horses and good torque - you wont be seeing that out of a blower. Nitrous is cheap but it isn't constant and you have to fill a bottle. Turbo is widely recognized as the replacement for displacement. Tuned turbo kits can punch your whp up to the 270s PLUS! that is the course i'm going to follow.
