TOMEI HIGH PERFORMANCE OIL PUMP SUBARU EJ20/25
Rotor gear diameter, gear thickness, teeth design, as well as the case body are all developed especially for tuned EJ20/EJ25 to be able support increased performance.
The increased flow rate, flow pressure and durability are whole different level compared to ordinary after market pumps that replace only the internal rotor gear.

From the case body, case cover to the rotor gear, everything has been redesigned and optimized for tuned EJ motor with increased performance.
Developed for more flow rate and pressure adjustment while maintaining precise operation from the Chromoly SCM435 rotor gear retained by both the front and rear side of the inner gear that reduces gear vibration and makes it strong and durable.
