It is true that unless it is BB (which I dont think it is) it doesn't need to be watercooled. I sealed off my water passageway holes. I'm running a journal bearing turbo now that didn't even come with provisions for watercooling. In that first picture, the nipple in the middle of the turbo is the oil inlet, and on the other side, in the second pic is the oil outlet. Since it is garrett you're going to need a garrett Oil return line. I got mine from Forced performance ( http://store.forcedperformance.net/m...e=Acc-OilLines ) BUT someone said that is a T2, and forced performance only sells DSM flanged and garrett t3/t4 flanged oil return so I am not sure if it will work. Looks like it will In my opinion though.

EDIT: I dont know what car that turbo is going on, but the flange on YOU'RE oil pan may not be the same as what Forced Performance sells in there oil return lines.
