Related question:  The normal oil source for the stock turbo appears to

have gone

through the engine and then goes to the turbo which means it is already

oil.  My T04 is not water cooled so I would rather lubricate the turbo

with cooler

oil.  Any suggestions on how I could safely do this?

A "T" in the oil return line from the oil cooler? Are you using a
metric to AN adapter where the oil cooler line goes into the block?
See picture with red arrow. Banjo fitting shown.

Thanks Paul,
I am using the AN adapter and it sounds like a very good place to use a to
tap off for the turbo (using a "T").  Do you think there would be a problem
with that much pressure from that point or is it pretty constant through out
the engine?

You might want to temporarily install a mechanical pressure gage at the point after
the T to see if it affects the oil pressure at that point. I have no idea
what the restriction through the turbo bearing unit is so even if I had
that data I would not know how to calculate the pressure loss if any :-)
