After talking with Hypergear where the turbo was purchaced, they have advised me that it was due to excess heat from a poor tune that the ends of the fins have been damaged.
Turbo has been sitting in the box since I bought it off Justin. I have not used it at all. I bought a different rear housing and was fitting it a few weeks ago (because my engine is finally ready to have it bolted on) and that's when we noticed the damage.
Pictures are all in the old thread but here is one of the wheel.
I paid good money for what I thought was a 800k old turbo. As you can see I am now in posession of a turbo that was damaged before it was sold to me. Not happy...
