Full-Race High Pressure Fuel Pump (HPFP) | 17-23+ Civic Type R FK8 & FL5, 23+ Integra Type S DE5

• Largest Displacement HPFP: The largest capacity high-pressure fuel pump available for any Honda application, offering 68% more fuel flow than the stock pump, without the need for a 5mm camshaft swap.
• Unmatched Power Potential: Capable of supporting up to 830 wheel horsepower on gasoline and 700 wheel horsepower on E85, this pump ensures your vehicle reaches its highest performance levels.
• Comprehensive and Easy Installation: The kit includes all necessary components for a hassle-free installation, with no permanent modifications required. The high-pressure tube replaces the OEM line entirely, eliminating the need for drilling.
• Integrated Pulse Damping: The pump features an integrated high-pressure pulse damping orifice, ensuring smooth operation and better control over fuel pressure.
• Fuel Compatibility: Designed to work seamlessly with both gasoline and E85 fuels.
• Hondata Tuning Support: Each unit is laser-marked with a unique Hondata keycode for easy tuning.
• Engineered to be the Best: We partnered with an industry leader in fuel pumps, Nostrum High Performance, in the development of this component. For this reason our customers know that they can rely on our fuel pumps to be the best built, best performing on the market.
• Limited Lifetime Warranty: Every pump is dynamically tested and backed by a limited lifetime warranty.

*Note - stock and XDI pump compatibility with 5 mm lift Hondata camshaft not verified.
Max Operating Pressure: 250 bar / 25 MPa / 3600 psi (OEM rail pressure sensor limited to 270 bar)
Max Engine RPM: 8400

*Horsepower and Torque numbers are approximate and can vary significantly depending on numerous factors including what supporting upgrades are done to the vehicle, ambient temperature, elevation, road surface, tire selection & condition, fuel octane and quality, vehicle weight, and more.  The advertised numbers herein are based on optimal conditions and utilizing proper supporting modifications.  Your results may vary.

Can the Full-Race Civic Type R High-Pressure Fuel Pump be used with aftermarket camshafts that have higher lift fuel pump lobes?

The Full-Race high-pressure fuel pump is intended for use with an OEM-sized 4mm HPFP camshaft lobe. We do not recommend using this HPFP with an oversized 5mm aftermarket camshaft lobe, due to issues with fuel pressure control that may result.

What is the benefit of a higher max operating pressure?

The higher operating pressure of the HPFP allows you to run the fuel injector at a higher pressure, sometimes higher than stock commanded pressure. This allows more injector flow (mass flow) by running the same injector at a higher pressure, like 240 bar (3500psi) rather than 200 bar (2900psi). Increased pressure at the injector improves spray quality and penetration, especially as boost pressure increases.  In highly boosted DI engines it's all about injector capacity and combustion quality (spray quality).

Why do your numbers say I will make less horsepower on E85 than 93 octane?

The numbers we list in the product descriptions are similar to the numbers a turbocharger lists for airflow. The numbers are the "fuel system capacity to generate power" regardless of the other engine system limitations (air handling, mechanical limitations, knock propensity). Essentially the numbers are calculated assuming "sufficiently large turbocharger airflow", "sufficiently capable mechanical assemblies", and disregarding knock limits. The equation uses actual observed engine volumetric efficiency (when available from sponsorship test vehicles) and fuel capacity (including target pressures) to calculate power. Gasoline has more energy per mass volume than E85. So the higher fuel flow capacity will mathematically generate higher power potential for gasoline than a high ethanol content fuel. The other variables (air flow, spark, rotating assembly strength, charge cooling, mechanical assembly strength) are highly variable from build to build. This is why we state horsepower capacity for the fuel system – representing the potential of the fuel system if you have all the other aspects of your build addressed!
