hi all... ive had my 07 wrx limited for a few months now... absolutely love it, but i want a little more power... im ordering an ap soon and want to know how to use it optimally... i have a turbo xs dp/mp and a helix tbe left over from my 03... i really need this car to be as close to quiet as stock (borla hush???), so i dont know if i can use that stuff... im not really sure how to approach the 2.5L... thinking about an sti turbo(good idea??? is stock turbo sufficient??) any suggestions on where to go???
as a base line, i had a 03 wrx stg II... looking for at least that amount of power, and a little more
