Correction, the turbine wheel is 53mm, the compressor wheel is 60mm.
That would make it a 2560.
How much boost can 2560 deliver?
It made a nasty screeching noise under boost, so I got a rebuild kit and rebuilt it.
(what a PITA to get the lower rear nut back onto the manifold stud...).
It still makes quite a bit of noise, not so bad under boost but once get off the throttle
it sounds nasty. Almost sounds like the stamped sheet metal disk behind the turbine
is making contact with the turbine wheel (the rebuild kit didn't come with a new one).
Since it still makes noise, I checked the oil flow, I got about a pint of oil after 20 sec
of idling, is that enough?
