got a fat wallet? S/C is about they only way to do it. Along with a Coverter ($800-1200) gear swap, headers, Diablo tuner is also a must $300...

I guess you could open the motor up and go with more cam, better intake bigger injectors but that stuff isn't cheap (like the blue oval stuff)

I have the K&N system, MagnaFlow exhaust and hit the computer with the diablo. So far the best time is 14.12 @ 97. (Mine is a heavy AWD Magnum) I think the 2wd is good for about 13.70 w/ the same mods. My main issue is how lazy the drive by wire is. It takes forever to get the car moving.
