I looked into Tim's when I did mine, but not any further than the web site and watching his videos. At that point, I decided that I could rebuild my own with the now unavailable Turbo Rebuild UK Mellet CHRA's. Was actually a pretty easy process as long as you take your time and are careful. Tim's is about an hour from my house, so if I have any future issues that come up on the turbos, I'll plan on taking to him if he's still doing them at that time.

It is all about finding the right person that knows them, and if he is comfortable with the RS6 units, sounds like a solid lead. When I looked for someone to rebuild my ancient T04 on my Callaway Rabbit, I found a company that had was familiar with that particular unit and had no problem fabricating bearings, etc. as needed and it came back looking and functioning like brand new. That was Blaylock Turbo somewhere in the midwest and was about the price for a single what Tim quoted per unit at about $600.
