Anyone want to take a stab at WTF happened here?

Background:

Back in November, I took my car down to the shop to remove my Bullseye turbine housings and install used, stock TD05 housings. The install went pretty smooth, and no unusual stresses were placed on the housings during or after.

Once I finished the car up, I drove it about 5 miles home, where it has been parked ever since. (Stored for the winter, and with the transfer case off for the spool project). When I drove it home, I wasn't able to get on it at all because of an ice storm. Since then, all I've done is let it sit in the driveway and run up to operating temp every few weeks. You can see the housing isn't even discolored from heat or corrosion yet. That's just the bare, sand blasted metal.

Interested in what you guys think.

Bad casting?

Add the heat and cold shifts from running in a MI winter and its just popped?
