I just bought my first WRX 2 weeks ago I live in AZ and was looking for a specific WRX 04-05 bone stock with under 100k miles and around $10k. I found my beauty, had to travel to Tucson to get it but its worth it. It's been 7 years since I was in the car "mod game" my first car was a integra then a civic followed by lifted Tacoma. I always loved the WRX but could never afford one till now! I appreciate any help and tips with my new project. I purchased a PERRIN intake first, loved the way it sound and It had a little more power. Next I just bought and installed PERRIN turbo inlet hose, I feel/hear turbo spool earlier now but starting around 3500-4000 It feels slower when I just had the intake on. Is it possible I have too much intake and not enough exhaust at this point?? Plus what should my next mod be besides the obvious dp and exhaust that it needs.
