Nissan Competition Oil pump can in two varieties: 1)high pressure and 2) external line version.

Overview

The Nismo oil pump generates an oil pressure of over 100psi and does not self-prime. It has two gears instead of the standard pump's geroid type (trochoid pump).

Instead of a rotor with lobes on it there are two gears that pump the oil. It also has oil cooler connections on the exterior of the pump.

The Oil Filter points down, exactly like the stock pump

Dry Sump Type

Part number 15010-M0821 is an A-series competition oil pump with a second stage. Looks just like any dry sump pump driven off of the camshaft.
