Oil Feed for Small Block Turbo

Disclaimer: I am not a turbo guy, my knowledge is limited to stock applications on heavy equipment, Cummins, and a short obsession with 2.2/2.5 turbos about 20 years ago...
IMHO, the 1/8 NPT port for the sending unit is waaay too small for a turbo feed line, for instance the feed on a stock Cummins is 3/8", so check the inlet size on the turbo you intend to use and match it. If you're going to run a remote filter or oil cooler setup, those would give you a good place to tap off a feed line of the appropriate size.
