I have a used GT 6131 turbo from Precision Turbo. It has a lot of shaft play and the compressor has hit the housing. I am sure it will need a rebuild. It was on my car durring wiping a lobe off the cam. Gotta love those #3 exhaust lobes. Anyway the turbo is in rough shape. There has to be some use for it yet. So I am taking offers. The waste gate actuator is still good shape.
