I am actually at the exact position you are in, looking for a answer on a simplest way to tap into the oil pan. Well I THINK there are 3 ways to do it: 1. drill hole with a driller in the oil pan by either by lifting the engine up to get the oil pan easily or by drilling the pan while the motor is in. 2. Use that gravity feed way 3. Use a scavenge pump or something like that.
Dont call me a dumbass if some of the stuff I said is wrong and doesnt make sense, I dont know too much about NA-Ts'

How much hp you looking for? I just want enough to beat a stock TT like around 350hp.

Here's the tool I used with the hole saw attached. I don't know the hole saw size, but just measure the diameter of the oil return hole at the bottom of the block. And yes, a plastic 90 degree drill adapter will work very well.

Of course, grease the hole saw, and take your time drilling the hole. You don't need a lot of pressure to go through the aluminum oil pan. Also, frequently clean the hole saw and regrease it.

First, the drill bit will penetrate the pan; then, it will take a little longer to get the hole saw all the way through. Again, don't apply a lot of pressure to the 90 degree drill adapter. If you do, you'll put more debris into the block.

Once you're all the way through, try to get as much debris out of the pan as possible with your fingers, but be careful. The hole will have sharp edges; try not to cut yourself.

Next, get a large NPT tap (again, I don't know the size) and tap the block. Finally, screw the fitting into place with teflon tape.

NPT is a type of plumbers thread that tapers from a narrow opening to a larger opening. An NPT tap is the same thing - a tapered tap. As you screw the fitting in, with the threads wrapped in teflon tape, the fitting gets tighter and tighter.

Someone please help me out here. :)
