I have lusted after one of these for a while. Not because it offers any actual advantage, in fact, for street use it can even be a disadvantage, but it's another genuine factory/Nismo competition part & I have a bit of an obsession with the rare factory/competition stuff.

These things put out about 100psi of oil pressure, so this will need to be tamed down a bit, back to something closer to about 60psi as this will be plenty.
Now I need to come up with a small oil cooler with a thermo by pass so that oil passes through the cooler only when the temp rises above a certain level to avoid overcooling.

The decal was discovered when I was looking for something else in among a bunch of early 50's race bike [bicycle] stuff in my study. I forget where I got it but I have had it for so long that I had forgotten about it completely.


































This is another competition pump, but is a good image of the internal workings & it's shown laying on its side. The left side of the pic is the top of the pump.
