The majority of parts you use will be OEM, and they function very well together. Stand back and tell yourself this is going to cost a lot of money. I can't believe how much I've spend on my LsVtec setup. I probably could've gone with a weeker forced induction setup, but this way, i'll be able to slam mustangs without saying them "thats not fair, you've got a turbo", but if you just want to go fast...then who cares what they say. I'll add my numbers up and tell you how much it's costed me so far
