i just recently purchased a 2004 srt-4 i was wondering what mods i should put under the hood. i am on a rather tight budget though

 

If you're on a tight budget, an intake and exhaust would be a good start. There's so much u can do to these cars. It obviously depends how much u want to spend.

 

Intake is not worth it unless you have a lot of other mods. It has been proven the stock intake can support over 300 HP. An exhaust would be my first, a wideband second, and a boost controller third. Do not turn up the boost until you have a wideband.

 

what exactly is a wideband and what does it do?

 

A wideband is a gauge that uses a 5-wire O2 sensor to keep you informed of the air/fuel ratio. It goes into the exhaust. You don't want to up the boost without one.

 

y not?

 

Seriously? If you push too much boost and the air/fuel ratio becomes lean, you can melt a hole in a piston, melt spark plugs, etc.

 

The car runs really rich from factory, so you COULD raise the boost a little, but I wouldnt go more than a couple psi without the above^.

Not just the catback though, that itself wont really help alot. Most of the power will be freed up from the addition of a 3" downpipe and o2 housing.

Back when I got mine, the Stage computers were really good mods to do, but now there are many options without them..diablo and the like.
