I have a couple of Questions here. First off Do I Need a new Downpipe When I put in my Turbo (I am running a T3/T4)? When I Get my injectors (450cc DSM Injectors) Do I need to have the O Ring Modified Or Not? Do I need to Get a new resistor Box? And Will I have to remove My AC? And Where Would I run the Second Part of the Innercooler Up through the Car. If somebody would help me I would appreciate it. Thank You.
