The kits we got just had seals and bearings. You had to completely dissasemble the turbo to re seal. The compressor and turbine wheels were indexed so the only went on one way. The turbo in the 930 got lots of work out after we rebuilt it so I know it was ok. I don't remember what ever happened to the Audi I rebuilt it when I was a young apprentice and now I'm an old bastardor so I'm told.
