done many times. The problem is after you spend $1000 on rebuilt factory turbos you still have bad seals. I have been a victim of this as well as many other TT.net members. If you do rebuild factory turbos you are looking at a car that smokes as bad as it did $1000 previous to rebuilding them. You can buy the brand ne chra's (unless your exhaust housings are cracked) and be alright but you are better off just getting some sport 500's.
