ShareDescription
One of our staple products is the RB oil pump. Oil flow and pressure are dramatically increased over those of the factory oil pump, which is critical in modified engines for the 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-style gears. Oil pump gear failure will result in inevitable engine damage.
With NITTO, the housing itself is made from a gravity cast casting, as opposed to a die-cast casting. EN26 inner and outer gears that are larger than standard size in order to guarantee strength, and redesigned oil galleries within the housing in order to allow for greater oil flow volume and oil pressure. It also features an aerospace-grade 7075 billet backing plate, and the kit comes complete with the gasket and front seal. The success of this oil pump has been well documented, with countless builds featuring our pump. Not only that, but also a significant number of builds that produce well over the 1000hp mark for drag racing and street applications.
NITTO RB series oil pumps are supplied pre-inspected, blueprinted, assembled, and cleaned to enable direct installation straight onto your engine and assure total confidence.
The oil pump kit comes complete with the gasket and front seal.
