exactly this ^^^^^ my brother spent way more turning his car into a turbo rather than just buying 1 to start with.. Like trento said it is def. not just a few grand. Ive lost count of how many times he said "I wish I just bought a f*ckin turbo car in the 1st place" + the headaches of getting it all in the car and making it all work properly... Personally I would just start saving for things like the big nizpro intercooler kit, SMB turbo exhaust, xcal 3, surge tank setup, injectors, valve springs, etc, oh and of course the car. With mods like these you'll piss in your 450hp. You would be best buying a model that is post 06/06 too so you get the stronger motor. By the time you can buy it they probly will have come down more in price too. Honestly everyone is saying the same thing for a reason bud... though it is your money so do what you want
