Designed for serious street and race applications, the ERS / Highspeed Engineering Billet Oil Pump is the ultimate upgrade for your Mitsubishi 4G63 Evolution engine. Precision-machined from high-grade 6061 billet aluminum and anodized for maximum durability, this pump delivers vastly improved oil flow and pressure compared to the OEM unit, while minimizing cavitation even at extreme RPMs.

At the heart of the pump is a robust gerotor design, supported by Japanese-spec precision ball bearings for smooth, reliable operation under the harshest conditions. The internal oil galleries have been 3D machined and flow-optimized to reduce restriction and improve efficiency throughout the lubrication system.

This oil pump isn’t just about brute performance — it’s also built with functionality in mind. A dedicated sensor port at the pump inlet and another on the filter housing allow for pressure and temperature monitoring, making it ideal for data-driven tuning and engine protection.

The included remote oil filter mount takes performance even further. It features an adjustable high-flow pressure bypass, turbo oil feed port, NPT sensor port, and dedicated temp/pressure sensor provision — offering complete control and adaptability for custom setups.

Whether you're building a high-revving track car or a bulletproof street machine, this oil pump ensures your 4G63 stays properly lubricated, even under extreme load.
