Can anyone identify this turbo?

I was wondering if anyone could identify this turbo in the photo below? The intake housing looks much larger then the exhaust side. Thoughts… guesses?

Hmm...compressor-housing looks like plain vanilla KKK K27 or 3DLZ, turbine-housing might be little smaller (K-26 hybrid?) but to me it looks pretty stock.

Can you post numbers off the turbo?

Hard to tell from this angle.
Looks like K-27 compressor, the hot housing looks like
a K-23 from a TT.
With the size diff. could also be a K-29 compressor
with a K-26 hot housing.
Both would be Hybrids.
What's it on?

The turbo is on a 930 that has been highly modified. The engine has been punched out to 3.5 liters, twin-plugged, GHL heat exchangers, etc.

Does the K-27 compressor housing have the multiple ribs on the top compressor port (see photo)? Every K-27 I've come across only has a single rib/lip on top.

What would be the advantage of a hybrid turbo?

I've seen them both ways, you can get adaptors
to match the neck with porsche down pipe.
K-28, K-28s, K-30, are all hybrids. The turbo builders
mix the compressors and hot housings to get more
boost, or quicker spool up. I run a K-30 on my car.
