R2P Gen 1 High-Pressure Fuel Pump Upgrade (350 Bar) – High Performance for BMW M140i, M240i, 340i, 440i and MINI JCW

The R2P Gen 1 High-Pressure Fuel Pump is the key component if you're looking to extract more power from your BMW with a first-generation B48 or B58 engine. Designed to withstand up to 350 bar of pressure and increase flow by 23% compared to the stock pump, this HPFP eliminates the bottleneck that limits demanding builds. Compatible with gasoline, E85, and E100, it guarantees a constant supply even in high-power ethanol configurations.

Key features

• Maximum pressure of 350 bar: Exceeds the 250 bar of the original pump, allowing higher-boost configurations with no risk of fuel starvation.
• Volume of 1.178 cc/rev: 23% more flow per revolution compared to the stock HDP-5-EVO (0.954 cc/rev).
• Ethanol compatible: Reinforced materials that resist E10, E85, and E100 without degradation.
• Improved internal valves: Maintain stable pressure across the entire RPM range, preventing critical drops under high demand.
• Direct installation: Plug-and-play; may require connector rotation or an extension cable on some models.

Why choose this pump over the stock one?

The original HDP-5-EVO pump is limited to 250 bar and 0.954 cc/rev, which causes pressure drops in builds over 400 HP or with ethanol-rich blends. The R2P Gen 1 offers 40% more maximum pressure and 23% more flow, with reinforced valves that prevent structural collapse under extreme conditions. Ideal for those seeking reliability on track or in demanding daily use.

Frequently asked questions

• Do I need to reprogram the ECU? Yes, to take advantage of the increased pressure and flow, an ECU tune is essential.
• Is it really plug-and-play? Yes, it fits directly into the engine. On some models it may require rotating the connector or using an extension cable.
• Can I use E85 without issues? Absolutely. The internal components are designed to resist ethanol corrosion without degrading.
