FS: Like new Nissport Oil Pressure adapter- mounts in stock opsu location (1/8 bspt), comes with a stock opsu. 2 of 3 of the 1/8 npt ports open, 1 port plugged. I used the open ports for a sending unit (electrical gauge) and the other for a .060 restrictor and 44 in Earls steel braided line for a top mounted T3T4 turbo oil feed.

This is my setup, let me know if this part will work.

Im putting a T3/4 50trim on my B13 SR20DE. I am planning on a Prosport Electronic Oil pressure gauge with the setup. Now Im almost 100% positive my turbo is a bottom mounted, just like a T28 setup. Will this work alright?
