I had the same issue on a Yamaha165 turbo, replaced it with a garret t3 had to do a bit of machining with the oil dump pipe, different hole centres but used the same exhaust side housing. Big bonus is you can get parts for the garret unit, bearings seals etc.
if you ever have the same problem it's easy fixed fixed for a few quid.
I must go down to the sea again to the lonely sea and the sky
All I ask is a tall ship and a star to steer her by
the wheels kick and the winds song and the white sails shaking
a grey mist on the seas face and grey dawn breaking
