I’m getting close to drilling my oil pan for the turbo oil drain, and I’m wondering how you guys routed your drain line. I know keeping AC/PS makes it much harder, but I need both systems.

Side shot, reference picture two.
Current oil drain flange, ~5” to a barb AN10 fitting
The tip of the barb almost rests on that one power steering line, so the hose has to go between the coolant hose & power steering line.
Roughly the area where NPT fitting will go into the oil pan. ~1.75” Barb to NPT.
Roughly the angle of attack the hose would come down through the engine bay.

Are you familiar with the trick where you put a hose over the drill bit to prevent it from going too deep? Slip a hose larger than your drill bit over the bit and trim it where you only allow the bit to stick out of the hose at the very tip. That way when the bit grabs and penetrates, it doesn't pull itself in and hit the oil pick up tube as easily. That location should be a little better for avoiding the oil pickup tube anyway, but it's in there.
And don't forget to use grease on the drill bit and on the tap and wipe them frequently. You will still get a fair amount of debris into the oil pan, no matter the efforts. Carefully reach in with a pinky and collect the errant shavings. A little heavy grease on a dry pinky can help them stick.

Yes, I’m using a spare piece of PVC pipe that has tip exposed. I started a pilot hole but ran out of time today.

I poured about 3 quarts of 0W-20 through the newly tapped hole, in addition to your recommendations + ~10 psi compressed air through the dipstick.
I do not no, it was just a customers car a while ago. It's not necessarily to put the drain way up there, but it gives you more room for a drill, wrenches for the fittings, room to put a bit of an angle on it, that sorta thing.
