Hello everyone i'm new at this site, but today I came here with a couple of questions... I have a 2001 2.4L twin cam Grand Am SE but I really want to do some mods to gain some extra HP, what can I do for it? and what can I do for an aggressive sound? I was thinking about putting a supercharger or turbocharger but what do you recommend for me?
Recently mods on the car: performance camshaft, air intake, autolite xp iridium spark plugs, racing thermostat and ported heads.
