So far I just have a catless UP, catted DP, exhaust so far on my 05 WRX. Just looking for some suggestions on where to go next. From what I've read it seems like the next steps would be injectors, fuel pump, upgraded turbo, etc. Considering I'm on a budget I'll probably get 1 or 2 parts every 6 months or so.

I'm pretty new to modding so any recommendations on specific parts, brands and order that I should get things would be greatly appreciated.

 

If you are looking at more power, changing the turbo out is a good way to get much more power. But you will need, Turbo, Injectors, fuel pump, and something to control the new fuel and boost levels. So a reflash, piggy-back ecu, or full out stand alone ECU. To really get the most out of the car.

One think I am planning on doing to my rally car is starting to control the intake and exhaust temperature more.

Overs a ton of upgrades that will keep your car reliable and increase the horse power on the stock turbo.

One think that I always wanted to try on the stock turbo is to port it and coat it and see how much better the car runs.

also making the car handle better and stop better is always a good way to spend money. What good is horsepower if you slam into a wall?
