It's only oil cooled. Good point about the mounting location, though if it isn't flowing enough oil I could imagine the turbo getting too hot. I'll talk to the tech tomorrow to see what he thinks about the ideal size of a restrictor. I got a call that they've finished with the rebuild ($375 ).

I was told it was new at the time I got ahold of it, and from the way it looked I can believe it. Though, I know I could clean up the turbine housing to make it look new too.
