The fittings into your turbo depend on the turbo. My GT2554RT was 14mm water fittings (1.5 thread) and the Oil In was a 7/16" inverted flare.
You want your oil in to be restricted (but no smaller than 1mm restriction for BB turbo), and your oil out to be about as big as your arm. Other than that, as long as oil goes in, oil comes out, water goes in, and water comes out, it really doesn't matter.
So you'll need:
2x 14mmx1.5 thread => -4AN fittings (these go into your water in/water out holes on your turbo)
1x 7/16"-24 inverted flare => -4AN fitting--preferably with a restrictor (you can find these on ebay pretty cheap) (this will go into your oil IN)
1x flange plate that matches your Oil Out, and a -10AN fitting coming out of the flange
3x -4AN stainless steel lines (one for water in, one for water out, one for oil in)
1x -10AN stainless steel line (for oil out)
2x -4AN => hose barb for water in and out
1x -4AN => 1/8" NPT for oil in
1x 1/8" NPT => 1/8" BPT (this is the thread of your current oil pressure sender, its slightly different from NPT)
1x -10AN to whatever fitting you stick in your oil pan for oil drain.
