Where is the turbo oil supply line on a 280ZXT?

hello,

Im in the final stages of parts ordering for my N/A-T swap and im hunting down fittings I will need for the build/startup of the engine. My question is where in the heck does the turbo get its oil supply from? I have a stock 280zxt oil cooler with the block adapter and it has a small plug on the side. would that be a good place to get the supply from? If not then where should I get it from? also will i need a restrictor of any kind if im using the stock 12mm banjo fitting? If so what kind of restrictor do I need? I planned to originally come off the oil pressure sender but it seems kind of ghetto to me if I can hook it up all factory like. let me know please or at least show me a pic. Ive been searching this for a couple of days, and its getting old looking.

I hope this helps, I actually created a thread on this about 6 or more years ago (yikes!) when I did this upgrade, you might find it if you search and add my username "slownrusty", but here are all the pictures from that original thread and some pointers:

 

Stock oil feed hard line to the turbo:

Stock oil fitting and sender to the gauge (bell on the right), threads on the right side of the block:

The parts (hose, fittings) you need for your new oil feed:

New adapter fitting that I had the opening welded in and then re-drilled for the oil restrictor

Re-using the oil fitting and then the I made the Earls hoses. Top hose is the oil feed with the above mentioned restrictor, hose below connects to my mechanical oil pressure gauge in the dash.
