So, I have the G6 GT with the 3.5l, and basically besides performance exhaust and CAI, there's nothing else to do to the 3.5l, preformance wise, that's relativley inexpensive to do? I wanna get some extra HP without like takin apart the engine and stuff like that. Im lookin for mods like, new fuel delivery systems, ignition system, turbo or supercharger, intake manifold stuff like that.
Also has any body heard of the JET performance moduel for the G6. If so, is there even a bennifit to geting it.
CAI, Headers If you have an 05-06 model,The rest of the exhaust,good sparkplugs,Tune.
If you really want get into Port and polish the Cyinder Heads and Intake manifold.
New fuel delivery systems $,$$$
ignition system Like MSD? not really need and also $,$$$
Turbo or supercharger You can but you will need to beefing up the trans,If you Did under 4lbs of boost you could proably get away with a shift kit, regular fuild chages and a Heavy duty cooler.... For awhile but it will take 3k to do right just for the trans. $$,$$$
