Seems like bad turbo. Need help!

Yes, I am talking about impeller.  Vanes have some wear on edges.  Most worn place is
from  shaft to midlength. So, there is not contact with housing.  Phil Payne suggested
it is a nut (from shaft, if I remember correctly).  I think if it happened it happened
before me because I did not find any object inside and I guess I could've hear some
noise from it.
I am trying to find why the car attain boot too slow and I feel lack of power compare to
my second car. That car has K-24 but the difference in response on stepping on gas is so
big  that I don't believe it is
