New turbo should arrive today.
My thought is that when the 7006 detonated the core assembly has realy been damaged beyond repair.
It had to be machined/honed for oversize bearings and now there is a discrepancy that when first put together runs fine on the VSR yet starts to fail after driven.
Hoping this weekend I will have swapped the turbos over and have some joy.
And no more
Steve.
