I live in Australia and having alot of trouble sourcing new turbos for a 2000 S4. There is a lot of refrence on the forum about going to RS4 turbos (KO4) but what are these GT turbos I am reading about? Does anyone know if there is a list somewhere saying whatturbos you can use on your S4?

 

Ok I just found another type Turbonetics T4 Series Turbochargers, what trim and AR would you order if you were going for these and are the ones I want, wet or dry bearing housing, dynamic or carbon seal? Any light on this subject would be greatly appreciated.
