Show original supplier description
The RPM Motorsports LNF 2.0L Direct Injection Fuel Upgrade Kit is an essential modification for those seeking to push the performance boundaries of LNF, LHU, and LDK engines, particularly when targeting over 400 crank horsepower. This comprehensive kit is designed to support builds aiming for up to 475 bhp on pump gas or 500 bhp on full E85, provided an ECM calibration is performed. The upgrade includes high-flow 135# per hour injectors to meet increased fuel demands. A key component is the GM-sourced High Pressure Fuel Pump (HPFP), engineered to deliver an additional 35% flow capacity compared to the standard factory 2.0 HPFP. Additionally, the kit comes with a precision C&C milled stainless steel adapter, complete with all the necessary hardware and seals for installation. This fuel system upgrade is instrumental for achieving peak performance in vehicles such as the Cobalt, HHR, Solstice, and Sky, among other GM platforms utilizing the LNF, LHU, or LDK engine variants. It is a foundational piece for advanced engine builds that require a robust and capable fuel delivery system.
