You also need to ask yourself if you're going to keep the car, how long, what about re-sale, parting out the car.....etc. I have nitrous and love it. Would I like a turbo/SC yes but don't have the funds for it right now. For the money Nitrous is a quick fix for speed. You'll need an aftermarket EMS to get the full potential out of Noz but you could run the OEM one. Probably 2K will get you a very nice set-up but it's all about choice. Have fun.
