Can you identify this turbo?

got this turbo from my work, but know one there knows what it is. I have spent hours searching online etc but cannot find anything.
Have search the number on the compresser housing but only got so far. Same with the numbers on the plate in the photo. The OD of the inlet snout is 2.2"
Any help would be much appreciated!

That's a KKK K16 Turbo from a Porsche 993/996 I think.

Really? Can't seam to line the exhaust housing up with anything of the sort. Will do some more research.
Thanks heaps for a direction to look into

Wouldn't bother fitting it!

Yeah I wouldn't use it, DP looks like it'd be a nightmare to fabricate!

Apart from the dump pump issue, is it a good turbo?
