Bad shaft and turbine housing?

[rick stark]

I'm taking apart my 64/71/14 (SBS) I had on the "project" truck to rebuild for the 04 tow rig. Upon my visual inspection I find these cracks. None of which are external. The big one on the right is about and inch and a half long and the little ones on the left are cracked the same way in different spots all the way around the housing. Would this be a cause of concern? I'm worried about a piece breaking of and trashing the turbine. With a new billet 64 or 66 comp wheel going in, I really would not want that to happen.

As for the shaft, the spots where the bearings are seem a little warn but I'm not sure due to lack of experience. Both spots seem smooth to the touch. Thoughts?

I could really use everyone's thoughts and would appreciate the help...

I bought a used s366 on here with about the same cracks and just ran it and didn't say anything, it's been run hard for 2 years and hasn't been a problem yet anyway.

I'm going to sack up and try it. Thanks for your help!
