When it comes to buying stuff for your car, cheaper is not always better in this case... cause lets say you buy this kit for $900, you put it in a tune it and all the good stuff... two months later you blow the turbo, then you have to buy a new turbo or rebuild it, then you intercooler loses pressure, have to buy a new one... then your motor blows and then your screwed.... So the money your going to pay twice just spend it once and not have to have a problems.... Trust me ive learned the hard way and so will you if you buy that cheap kit
