Description

The Tomei Oversized Oil Pump is a high-performance upgrade for engines like the RB26DETT, RB25DE(T), and RB20DE(T). It addresses the oil starvation issues that can affect tuned RB engines at high RPMs by significantly increasing oil flow. Constructed with a durable SCM435 gear material, this oil pump boasts a flow rate of 56.0L/6000rpm, which is a substantial increase over the stock 46.7L/6000rpm. This enhanced flow is achieved through a larger outer gear diameter of 97.5mm compared to the OEM's 81.0mm, and a gear cover thickness of 7.6mm (stock 6.9mm). The overall gear thickness is also optimized at 9.5mm (stock 11.0mm). While compatible with the factory oil pan, it is highly recommended to use a larger capacity oil pan when installing this oversized oil pump to further support the increased oil volume and pressure.
