Above is a link to the Holset repair manual.
Sounds to me like the thrust bearing is shot ad needs replacing. These turbos are easy to rebuild and the kit is about $100 in the US.
Don't know what it would cost for you.
I have rebuilt a few of these and as long as you mark the orientation of the nut when you remove the compressor wheel the balance should stay ok.
When you do rebuild make sure you find out the reason this one failed. Perhaps it is not getting enough oil? Or is salt water getting in?
Hope this helps.
