i can really say this, i dont really care what a honda motor was design for, im worried about what im tryin to do with it, far as if i wanna drag, auto cross, or rally racing, the engine needs to be blue printed for it, engine biulding is infinite, because its never perfect, u can allways find more, i believe thses hondas can gain more than 80-100hp allmotor, ie. k20-k24 hybrid, 220hp hybrid swap, making about 315whp, not really im pressive, but the times these motors run r impressive (skunk2 9.63@141mph) now thats crazy with just a lil over 300hp and 200lbs/ft or torque, instead of using individual throttle bodies i'd rather use side draft carbs to make more power
