Give it back and get your money as that one will end up costing you more than it's worth.
Spend a little more or wait for a GOOD deal to come along if you can.
That turbo says stay away from me all over it.
Rebuild center section, also a new compressor wheel, it's junk if contact was made, plus turbine housing probably would need to be replaced.
Take the compressor cover off and see if it made contact with wheel.
Check the thrust bearing for in and out play.
These are some things you can do yourself to diagnose the problem before sending it out only to pay someone to tell you it's junk.
Brian will help you if you post pics of it and he'll tell you whether it's worth the money to fix it.
