So I see most generic turbo diagrams calling for 1 oil inlet and 1 oil outlet. But I found a 3rd port on my snail. I have no idea what the middle (3rd one) is, and I want to be sure before I put the top end back on the car. Of course feel free to correct me if I have any of the ports labeled wrong.
Inlet? (Top of the turbo)
Outlet? (Bottom of the turbo)
And...?? (between inlet and outlet)
The fitting for a hose to go on would be oil drain. Opposite of that would be the oil inlet and the holes on the side of this would be coolant inlet and outlet
Boom. Found the other hole (opposite the mystery one) and the fitting for it. As well as the coolant lines. Everything is all screwed on here, and the only open hole is the one I was originally asking about. Is there a particular place it's supposed to run to?

The port I indicated as the only one being left open, which was the silver-bezeled one I was asking about initially.
Actually on second thought. If it's the oil return outlet, shouldn't I just be running it down to the oil pan?
Yes to the pan. What engine is this for? I know my sr20 has a port on the block for the drain, which lead to the upper oil pan
It's the CA18ET. I haven't taken a hard look under the hood yet, as the head and everything was already out when I got the car.
I think the first two pictures are the coolant in/out and your "mystery" connection with the silver hose connection is the oil drain (non pressure), you connect a hose to the turbo oil drain to a hose connection in the oil pan. The forth threaded connection you found wound be the oil inlet. Looks like a T25 turbo isn't it?
