I was told that buying a used turbo was like buying used food. This came from the owner of United Diesel service in Alexandria Va. This gentleman is German and has been in the "diesel" busines for 40 years. I bought a garrett remanufactored turbo from him after seeing what a overhauled turbo looked like. Overhauled only replaces the worn-out parts and bearings...leaving you with old parts in your turbo. Remanufactored replaces everything...cost me $600. To overhaul mine would have been $300-$400 depending on parts. If you know the source of the tubo and trust the person... and the tubo has low miles...I would have bought a used one...but none to be found. Good luck.
