What are some simple ways to increase Horsepower in a Honda?

it is hard to say considering i do not know the specific car, but here are some general mods that will improve general preformance and horsepower....cold air intake, exhaust system, new cam, bigger gears, port and polish heads, supercharge or turbocharge it(this will be pricey $1000+ but will add near 100 more horsepower), new ignition wires(faster throttle response), and the always stated, what you dont need, get rid of. Overall, i suggest getting the cold air intake and exhaust system. these are probably the cheapest and will make your car much more gas effecient and will add SOME horsepower. hope this helped:)
