What is the small flange on top and the little tube on bottom?

 

looks like water inlet/outlet to me..

 

Really? seems odd to run water through there...wouldn't there be corrosion issues? Think it matters which is inlet and which is outlet?

Sure their not oil lines? I mean, I see the freeze plug on the side so it very well could be the water.

Where would the oil ports be?

 

The other threaded ports i would guess are the oil.

most production turbos are water cooled.
