4Piston Racing Oil Pump Fitting Kit for Honda K20Z3 & K24
The 4Piston Racing Oil Pump Fitting Kit for Honda K20Z3 and K24 engines provides the Genuine Honda components required when installing the 4Piston Racing 4PR-KPUMP on compatible Honda K-Series engine builds.
Unlike K20A, K20A2 and K20Z1 applications where the conversion can be more straightforward, K20Z3 and K24 engines require additional installation components to correctly fit the 4Piston Racing K-Series oil pump. This fitting kit brings those essential Genuine Honda components together in one package.
Whether you are building a fast-road K24, high-RPM K-Series engine, track car or dedicated competition engine, using the correct oil pump installation hardware is essential for achieving a properly assembled and reliable oiling system.

Why Is This Kit Required?
The Honda K-Series family uses several different oil pump, chain, guide, windage tray and balance-shaft arrangements depending on the exact engine specification.
When fitting the 4Piston Racing K-Series oil pump to applicable K20Z3 and K24 engines, the original engine configuration requires additional components to complete the conversion correctly. This kit has been assembled specifically for that purpose using Genuine Honda parts.
It removes the need to individually source the required Honda components and is particularly useful for engine builders carrying out a K24 oil pump conversion or building a performance K20Z3/K24 engine.
Designed for the 4Piston Racing 4PR-KPUMP
This fitting kit is intended for use with the 4Piston Racing 4PR-KPUMP K-Series oil pump.
4Piston Racing developed its performance oil pump range for demanding K20 and K24 applications where sustained engine speed, elevated oil temperatures and motorsport use place increased demands on the lubrication system.
The manufacturer offers dedicated installation hardware for K20Z3 and K24 applications, making this kit an important part of completing the installation correctly.

Genuine Honda Components
Rather than relying on generic replacement hardware, this kit uses Genuine Honda components. This gives engine builders the benefit of OEM-quality component dimensions, fit and finish when completing the oil pump installation.
The kit includes the components required around the oil pump installation such as the oil pump drive chain, chain guide, windage tray-related components and installation hardware.

Honda K-Series Compatibility
This 4Piston Racing oil pump fitting kit is designed primarily for compatible:
- Honda K20Z3 engines
- Honda K24 engines
- Honda K24A-based performance builds where the corresponding 4Piston Racing oil pump conversion is being carried out
- K-Series engine conversions using a compatible 4Piston Racing oil pump setup
Important: Compatibility should be determined from the engine code and oil pump configuration rather than the vehicle model alone. K-Series engines and K-swapped vehicles can use different oil pans, oil pumps and supporting components.
Always confirm your exact engine code and planned oil pump configuration before ordering.
Ideal for Performance K20 & K24 Builds
This fitting kit is particularly suitable for:
- Honda K24 performance engine builds
- Honda K20Z3 engine builds
- K20/K24 hybrid engine projects
- K-swapped vehicles
- High-RPM naturally aspirated engines
- Turbocharged K-Series builds
- Supercharged K-Series builds
- Track and motorsport applications
- Competition engine builds
- Engine rebuilds incorporating a 4Piston Racing oil pump upgrade
Why Upgrade the K-Series Oil System?
Oil control becomes increasingly important as a K-Series engine is modified for higher engine speeds and demanding track or competition use.
The oil pump is responsible for supplying lubricant to critical engine components including bearings, crankshaft journals, camshafts and the valvetrain. A properly configured performance oiling system therefore forms an important part of a serious Honda K20 or K24 engine build.
The 4Piston Racing oil pump itself is designed specifically for performance K-Series applications, while this fitting kit supplies the supporting Genuine Honda components required for compatible K20Z3 and K24 installations.
Important – Oil Pump Not Included
This product is the fitting kit only.
The 4Piston Racing 4PR-KPUMP oil pump is NOT included with SKU 4PR-GEN-HON-Z424-4PROP and must be purchased separately.
Please do not order this product expecting to receive the complete oil pump assembly.
Installation Advice
Installation forms part of the engine lubrication system and should be carried out by someone experienced with Honda K-Series engine assembly.
Before installation, confirm:
- Your exact Honda engine code
- The oil pump being installed
- Oil pan compatibility
- Oil pickup configuration
- Oil pump chain and guide arrangement
- Correct Honda tightening procedures and torque specifications
For modified, K-swapped or competition vehicles, professional engine-builder installation is recommended.
