OVERSIZED OIL PUMP RB26DETT RB25DE(T) RB20DE(T)

The RB26DETT engine is prone to oil lubrication issues during high-performance driving (circuit and drag racing), which often leads to engine failure. This results in abnormal wear of main bearings due to insufficient oil pressure. The stock oil pump cannot supply adequate oil pressure at the extreme engine speeds required by high-powered RB26 engines. Additionally, the stock pump's weak sintered metal gear is prone to breaking under increased power and higher engine speeds, which can cause instantaneous engine loss. The TOMEI RB26 oil pump features a larger pump gear made from high-strength materials, providing a greater oil flow rate to the engine. It also includes an external oil pressure adjuster.
