I know this question has been asked a few times, and I read previous posts, but those where from the pre 2004 models. I basically have some what of a vague idea of how tuning for these cars work. I would want to clear up a few points, get other users experiences, and perhaps make this a sticky.

From what I read the only respectable tuning company is Paramount Performance, but they are quite the $$$.
- There are upper and lower blower pulleys? some giving 1.5 others giving 2.5 lbs of boost. Which to use?
- With the pulleys i read that better performance is noticeable, but a thermostat or some other type of cooler is required if you are going to be driving hard for 20 or more minutes.
-Exhaust= Minia gallery, is it worth it?
-ECU tune- would it be better to do it after all these mods are done?
-What other mods are there?

I am trying to break into a 4.8 sec mark for the 0-60. Sorry if these questions have been asked, A direct link would be appreciated.

Thanks in advance

 

I think you could break or get close to the 4.8 mark with a stock car. Like all drag racing....you can make all the power you want, but it useless if you can't hook up.
