Well, sounds like your pretty green so I'd like to say welcome! My best advice I can possibly give is A. Google tuning garages in your local area- swapping a turbo is a lot more than what it sounds, mainly cause you do not want to choose a wrong one or wrong supporting mods. The tuner can also help you answer questions like, what numbers do you want to see? What are it's uses? Ect. B. Look through the threads, this topic has been beaten to death, I'VE even asked it lol, so there is a lot of good info out there. Just buckle down, don't get overwhelmed or discouraged, and you should end up with a pretty sweet ride!
