Turbos good?
I went to see a low mileage set of 99 Turbos.
The seller was very cool and I would have bought them there on the spot but...
Anyone have any idea what might have been going on with this set of turbos?

- Neither of the pinwheels would freespin in the housings. The most freewheel I could get out of them was about 3/4 of a turn. I am not sure if this was normal in the 99s with the abraidable material in place?
- On the secondary, as I turned the shaft by the nut, there was no lateral motion, however one of the vanes (just one) of the compressor wheel would scrape the abraidable material. That seemd to indicate to me that either the ab liner was somehow out of alignment, or the turbo had one vane that has a larger radius than the others and is therefore out of balance? Is this possible?
