Too much heat retained in the housing causes that, similar thing that happens to exhaust pipes when you heat tape wrap them, the material structure breaks down with time and the end result is above.

*You must never ever insulate exhaust components or turbine housings* a heat shield is the only option to run, something with an air gap that can allow the heat to be rejected and flow away is the ideal.

A few posts back I reached the limit of this turbo in terms of the performance (over speed, too much turbine pressure) so I changed it. New turbo is my own specification
