I have half the parts for Turbo but it isn't a one week process and which alot of people forget you have to speed 1k on the clutch on top of 3k for a true good turbo set up also tuning on top of it<And come with alot of headaches from what I've read>. That more then half the value of our cars. These NA upgrades Tom listed will help while still NA give you some fun and help you alot more once you FI, and I'm half way and thinking if I want to buy a new clutch 1-2 years having it be my DD. You'd be suprized what a SVT with 30-40 NA hp feels like.
Turbo Build coming!
