I want my car to be faster then the STI! Which Mod would be the best to have this completed? I want it to be a daily driver and a reliable car. Plus I want it to be cheap? any sugestions?!

 

A turbo-back exhaust will make more than enough power to overcome the difference and is totally reliable. Should cost about $1000 or so from any number of vendors/manufacturers.

 

Buscher and a few other companies’ sell the AFC with their own "tune" for under $400 (I'd still tune it with wide band)

Works reflash for under $500

Shiv's got his own system also, but I don't know how much $$$

Most of these have dyno'd at or over 20 whp which will more than meet your modest goal.

 

My vote's for an AFC or reflash also.
