^ Yes, exactly. You want the most direct path without a bunch of bends or restrictions. Basically, you want to mimic the stock return line, like so:
I'd even go a step farther than the picture above and replace that 90 degree bend with a 45. I also wouldn't use anything smaller than -10 AN. Keep in mind, the primary thing that allows oil to drain off the turbo is gravity, hence the drain line design being so important.
Here's a good example, although I'd replace the hose clamp on the turbo side with an AN fitting:
For your car, the turbo side flange is probably the standard Mistu flange (shown as PSI-FLG-MIT), but you'll need to measure it and verify. For the bottom, it's anyone's guess since it looks like someone welded a female bung into the pan. Judging from the previous work I've seen, I'm guessing it's something uncommon, which will make your life hard.
Whoever you got this car from was an idiot. The last time I saw so many hack jobs in one place was back when I owned 1813. I apologize if some of my posts come across and asshole-ish, but I'm here to help. Don't let me discourage you from posting. You're doing to right thing by fixing all this crap, so let us know what else you find, and if you need more help with the drain. You have my number as well, so feel free to hit me up there too.
