Red Alpha VR30 RA338 High-Pressure Fuel Pump Kit | Stage 2 Direct Injection Upgrade | Fits 2016-2024 Infiniti Q50/Q60 & 2023-2025 Nissan Z | VR30DDTT | 600+ WHP Fueling Support
Fuel your 2016-2024 Infiniti Q50/Q60 or 2023-2025 Nissan Z to 600+ WHP safely with the Red Alpha VR30 RA338 High-Pressure Fuel Pump Kit, because the factory VR30DDTT direct injection high-pressure pump becomes the main restriction once you add intakes, full downpipes, and E30/E50 tunes, causing rail pressure to crash and AFRs to lean out above 450-500 WHP, while this Stage 2 RA338 kit uses an upgraded high-flow internal mechanism and larger cam follower displacement to increase fuel volume by 38% over stock, holding stable 2,900+ psi rail pressure all the way to redline for consistent fuel delivery on pump 93, E30, E50, and full E85 setups, and it’s a direct bolt-on for all 2016-2024 Infiniti Q50 3.0t Luxe, Sport, Red Sport 400, and 2016-2024 Q60 3.0t Luxe, Sport, Red Sport 400, plus 2023-2025 Nissan Z Performance and Proto Spec VR30DDTT models with no modification to the fuel lines, cylinder head, or cam required, and the kit reuses your factory low-pressure fuel system and injectors while eliminating the need for port injection on most sub-650 WHP builds, and every RA338 pump is bench-tested and flow-matched to ensure consistent pressure and volume before shipping, and it includes a billet fuel pump adapter, upgraded Viton seals, and all necessary OEM-spec hardware for a leak-free install using factory torque specs, and the pump retains full compatibility with stock ECU, JB4, and EcuTek tuning so your tuner can scale the fuel tables properly without rail pressure compensation issues, and the increased headroom prevents high-RPM fuel cuts, injector duty spikes, and dangerous lean conditions that cause knock on big-turbo or ethanol VR30 builds, and the hard-anodized housing resists corrosion from E85 while the internal components are E85-rated for long-term reliability, and installation takes under 3 hours with basic tools and the pump sits in the OEM location so there’s no noise, clearance, or heat issues, making the RA338 the best Stage 2 fueling upgrade for Q50, Q60, and new Z owners pushing past bolt-ons into hybrid turbo or full E85 territory who need reliable, direct-injection fueling without the cost and complexity of port injection.
