For a while i have been researching on how to upgrade my a4 which is a 2.8L. I have been looking up different things and want to know whether or not i could use a turbo from a '01 a6 2.7T or maybe the t6 turbo off a volvo s80. Also i have found universal intercoolers made by mishimotoh.But were am i going to find the tubing for the system. I also dont mind not having a/c so if anyone has any knowledge please let me know
