I purchased a used c39 off a forum member awhile back, knowing good and well of the issues the turbo is associated with. The seals have been replaced on this unit, and came off of his car in fully functioning condition. At the time I was aware of having the option of sending the turbo back to the shop just to get checked out for piece of mind. I’ve recently looked into possibly having that done, but it looks like robs automotive has shit down. Can anyone steer me in the direction of where I could have this turbo checked out? Or am I out of luck and should just bolt it on and hope for the best? Any help is appreciated
