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 critical piece when you're looking to extract more power from your BMW with first-generation B48 or B58 engine. Built to handle up to 350 bar of pressure and increase flow by 23% over the stock pump, this HPFP eliminates the bottleneck that limits demanding builds. Compatible with gasoline, E85 and E100, it guarantees consistent supply even in high-power ethanol configurations.

Features

• 350 bar maximum pressure: Exceeds the stock pump's 250 bar, enabling higher boost setups without risk of fuel starvation.
• 1.178 cc/rev volume: 23% more flow per revolution versus the stock HDP-5-EVO (0.954 cc/rev).
• Ethanol compatible: Reinforced materials that withstand E10, E85 and E100 without degradation.
• Upgraded internal valves: Maintain stable pressure across the entire rev range, preventing critical drops under high demand.
• Direct installation: Plug-and-play; may require connector rotation or extension cable on some models.

Why choose this pump over stock?

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

FAQ

• Do I need to remap the ECU? Yes, tuning is essential to take advantage of the increased pressure and flow.
• Is it really plug-and-play? Yes, it fits directly on the engine. Some models may require rotating the connector or using an extension cable.
• Can I run E85 without issues? Absolutely. Internal components are designed to resist ethanol corrosion without degrading.
