Subaru wrx in need of perfomance upgrade


Recommended Posts

I don't really know where to start, so I am asking for any suggestions on what to upgrade first? (that wont make me go completely broke)

I have a 03 subaru impreza wrx sedan that has 20k miles. (as of 10/1/13)

any suggestions will help. thanks

I am also looking into a new alternator because I have some severe light dimming.

Join a WRX forum and read up on there. There will probably be more consistent results there. An 03 with 20k miles is great mileage.

I agree with n8 bit upgrade all of your plumbing uppipe down pipe inter cooler piping ect. not just your intake. Also if money allows upgrade your inter cooler but that gets expensive. You can get a nice turbo upgrade known as a disco potatoe but I also say get on a wrx forum to learn more. I haven't worked on those types of cars since I lived in Japan.

Tune, tune, tune... Intake and intercooler are fine.. Look at a good down pipe look in to access point (Cobb tuner) BOV is ok till you get up in boost. its a vent type. Larger turbo is another option.
