Well this is how things stand at present, turbo is apart, impeller cold side is fine luckily.
Compressor housing is fine and has been cleaned.
Failure was hot side cartridge which in below picture is the part at the back of the shaft away from impeller
In the below pic you can see where the hot side turbine was slightly touching the exhaust housing.
New Gt30 bearing kit on route, and also a slightly smaller exhaust housing is on the way with hot side turbine.
