Nitto Hi Flow Oil Pump for NISSAN RB26 GTR RB25 RB30 & Tomei Jun RB26DETT
Description

Oil Pump - RB Series

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 style gears. Oil pump gear failure will result with inevitable engine damage. For this reason EN Series billet steel material is utilised for the manufacture of NITTO RB series high volume oil pump gears which are far superior in strength and durability to that of both factory and its competitor’s oil pump gears.

NITTO utilizes their precision CNC machined cast alloy outer housing and along with their already proven oil pump design NITTO has now released a new billet alloy backing plate allowing further stability to oil pressure and flow at high rpm levels by minimizing any possible flexing of the housing.

NITTO RB series oil pumps are supplied pre-inspected, blue printed, assembled and cleaned to enable direct installation straight onto your engine and assure total confidence.

Tomei reached 50 years in 2018. Seiichi Suzuki was a NISSAN Works Team Driver as well as a mechanic, and other “JOHOKU RIDERS” launched “TOMEI MOTOR Inc”. That’s right,”TOMEI” was created as a consequence of those car guys. Although “TOMEI MOTOR Inc.”later changed its name to “TOMEI POWERED”, its spirit and passion has been inherited, just for more powerful and stronger engine. In the very beginning we started of as a racing constructor of NISSAN type engines only and since day one we have produced & tuned many racing engines. Our standard procedures with the biginning of each new engine development, is to thoroughly inspect each engine component thoroughli for every aspevt of each part after disassembling and cleaning each part. This is our daily routine and habit. We foumd this to be the best procedure to find and address the engines good points, weak points and it helps us to accurately re-evaluate it for its new purpose. We then rebuild it and make it close to the original but a new stronger complete ideal balanced engine. This is the basic procedures of our complete engine development. We now make many complete engines of various brands and we’re not only limited to NISSAN engines. But our procedures and goals remain the same since day one. We never neglect anyone nor do we risk taking any shortcuts as to make a better engine will always take time to forge every engine to perfection. The end result is a complete product which has passend all these enduring processes to brimg the best performance available that both we and the end user can be proud of and have every bit of confidence in our products and their cars performance. TOMEI will keep challenging to make you satisfied.
