Tomei High Performance Oil Pump Nissan RB26DETT

Tomei began operations in 1968 as a race car tuner in Japan. Over the last 40 years Japan has emerged as one of the leaders in automotive research, racing, and culture. Tomei products have been utilized in nearly every motor sport imaginable. Tomei’s racing heritage means their research and design team have first hand knowledge of the extreme demands racing puts on an engine. Using only the highest quality materials means that Tomei’s products can handle the intense strain and heat a purpose built engine will experience whether it be on the street or the track. Tomei’s attention to detail is second to none. All of their products are thoroughly researched and engineered to achieve optimal efficiency. Because of even miniscule differences in measurements can cause catastrophic engine failure, all Tomei products fall within strict tolerances. Tomei machines all of their engine components to enhance airflow and ensure proper fitment and seal.

The RB26DETT engine is often plagued with a lack of oil lubrication during circuit and drag racing events. Insufficient lubrication is the main cause of RB26 engine failures. This problem causes the main bearings to abnormally wear out from the lack of oil pressure. The stock pump is not capable of supplying the adequate amount of oil to maintain the right oil pressures at extreme engine speeds that the high powered monster RB26 performance engines require. Another weak point is the stock pumps gear. The stock oil pump’s gear is made from weak sintered metal which often breaks when when used in a higher powered engine operating at high speeds. The failure of this one tiny gear means your engine will not be lubricated and your entire engine will be destroyed. The Tomei RB26 oil pump has a larger pump gear made of high strength materials to supply a larger flow rate to the engine and it has an external oil pressure adjuster as well.
