But this is the internet so that information is of little relevance ;)
Do it the turbobricks way. Slap on a huge turbo, turn the boost up, make yourself feel good. Im sure someone could sell you a GT35 and you can just run browntops with a 3 inch AFM with the resistor trick. Then make 250whp while a car with the same or less hardware pumps out 400whp because they are doing it properly.
Really we have no business telling you what to do with your time or money so can someone sell this man a turbo? Maybe just find the biggest one you can find on ebay and just run that?
