from one lx owner to another, do yourself a favor, and don't spend money on engine mods for the car.

i/h/e doesn't yeild much power for the money you're spending.

just focus on other things, stereo, exterior/interior, suspension, things like that. leave the engine stock and enjoy the good gas milage

if you want to go fast, be prepared to spend alot of money on a motor swap. but since you're 16, just use the car to learn to drive.
