I just rebuilt my gtir t28, the insides of these turbos are not that complicated. Either the oil in them burned to the point that the journal bearings are caked and totally locked, or a snap-ring broke and lodged it's self into a bearing. The worst would be the turbo came unbalanced. The impeller shaft would have ground it's way through the bearings, and the turbine and compressor fins would have eaten their way through their respective housings and possibly fused.
Your either buying a paper weight, or a turbo that needs to be soaked in parts cleaner and rebuilt.
Ask him to spray carb-cleaner into the oil inlet and let it soak over night. If it's free in the morning and the side to side shaft play is minimal, go for it. It will still likely need a rebuild. The kits are on ebay for about 50 bucks. It's fun to do.
PS I'll post the rebuild write up soon, just need to format the post and organize my pictures.
