I got a friend looking to put some decent hp upgrades on his car... what all companies make superchargers/turbos for this car and what all companies make exhaust whatever you guys got let me have it i that would be great. I'm not really familiar with these cars so I figured I would ask you guys!! I could use exhaust... chip...supercharger or turbo...gears? Just if someone could give me a mod list with a nice 1/4 mile time or something of that sort any help would be great. Thanks.
