You can buy a "Tee" - no drilling required... you'll just have to figure out the thread size / pitch of the oil pressure sensor.

This is what I'm doing turbocharging my winter beater

I think your getting mixed up - your going to have to tap the pan for the oil return from the turbo.

You can use a T connector off the oil pressure switch mount - one for the oil pressure switch and one for the turbo - don't forget to restrict the oil pressure to the turbo - 25ish psi will be good and just bathe the turbo in oil - not spray it on.

I haven't heard of anyone restricting pressure in the oil feed line... got more info on that one?

For the return line you can go with drilling the oil pan or if you have an i motor you can take advantage of the oil return line from the oil cooler.

The oil pressure is reasonably high in the car - if you spray oil onto the turbo - its not going to be happy. It wants to be bathed in it. I can try find some articles for you.
