Description

The NITTO RB series high volume oil pump is a high quality performance aftermarket oil pump that will suit Nissan RB20, RB25, RB26 and RB30 engines. Oil flow and pressure is dramatically increased over that of the factory oil pump which is critical in modified engines for reliability of the lubrication system. Failure of this system is the ?Achilles heel? of the Nissan RB series engine even on mildly tuned examples and accounts for a high percentage of ?RB? engine failures.

Factory based oil pumps are highly prone to oil pump gear failure in modified engines due mostly to the quality of the cheaper mass produced material used in the manufacturing of the OEM Nissan gears. Oil pump gear failure will result with inevitable engine damage. NITTO Oil Pumps have EN Series billet steel material which are far superior in strength and durability to that of both factory and the competitor?s oil pump gears.

NITTO utilizes their precision CNC machined cast alloy outer housing and combined with billet alloy backing plates to further stabilize oil pressure and flow at high rpm.

Quality control is tight as NITTO inspects, blue prints, assembles and cleans the oil pumps to enable direct installation straight onto your engine and assure total confidence.

The NITTO Oil Pump Gears feature Precision EDM Wire Cut EN Series Billet Steel
The NITTO Oil Pump housing has a Precision Cast and CNC Machined Alloy Outer Housing and?7000 Series CNC Machined Billet Alloy Backing Plate
