Ok first of all, if you dont know....

Its the blind leading the blind.
The oil sending unit is NOT A US, A/N, OR ANY OTHER STD PIPE THREAD. It is a BSP thread.
To feed the turbo, you'll need a bsp "tee" fitting (we do offer these). One side of the tee screws into the block, the other side the oil sending unit, and the last side the turbo feed.
To return the turbo, you need a custom flange on the turbo (again we offer these) and you'll need a -10 oil bung to weld into the oil pan. You'll need to remove the oil pan to do this.
As for the water, its not 100% needed although it does help.
To plumb the water, remove the N/A water nipples on the back of the thermostat manifold and either run water lines off them, or get a pair of turbo water nipples.
