Description

ER300 K-Series Engine Package

The ER300 is Elusive Racing’s track-developed, high-performance Honda K-Series engine package, engineered with one clear priority: reliable performance under demanding conditions.

Developed in-house at Elusive Racing, the ER300 program combines carefully selected components, proven engine-building methods and extensive real-world track testing. Rather than building an engine purely around a peak dyno figure, our focus has been on creating a package capable of consistently performing through circuit racing, endurance use and repeated high-RPM operation.

Built to Perform. Developed to Last.

The ER300 has been developed and tested through our own Honda Civic EG race car, allowing us to put the package through the same conditions our customers expect it to survive.

Continuous track testing and data logging allow us to evaluate engine temperatures, oil control, RPM, reliability and overall performance under sustained load. What we learn at the track is carried directly into the engines we build for our customers.

ER300 Package Highlights

• Honda K-Series Platform
  Available in multiple configurations including K20 and K24/K20 hybrid combinations, depending on the customer’s application and performance goals.
• Track-Tested Development
  Developed through extensive testing in Elusive Racing’s own EG and EK Civic race cars, rather than relying solely on dyno testing.
• High-RPM Capability
  Selected ER300 configurations can be built for high-RPM operation, with engine speed capability determined by the individual specification, supporting components and intended use.
• Proven Performance Components
  Depending on specification, ER300 builds utilise components from leading manufacturers including Manley, Supertech, Skunk2 and ACL, together with our selected piston, valvetrain and rotating-assembly combinations.
• Built for Reliability
  Component selection, machining, clearances and assembly are designed around the demands of sustained motorsport use not simply achieving a headline horsepower figure.
• Application-Specific Builds
  Every ER300 can be configured around the vehicle’s intended purpose, whether it is a high-performance street car, naturally aspirated track car, time-attack build or dedicated race car.

More Than a Dyno Number

The ER300 philosophy is simple: power means very little if the engine cannot consistently finish sessions.

Our development program focuses on producing a K-Series package that delivers strong performance while maintaining the reliability required for repeated high-RPM and high-load operation.

The result is an engine package developed through real motorsport experience, real track time and continuous testing.
