Fuel Injectors - 87.8LB/ HR (8pk) GM LS2

The Fuel Injectors - 87.8LB/HR (8pk) GM LS2 by FAST Electronics represents a precision upgrade for LS-series engine builds seeking refined fuel delivery and reliable performance across a wide power range. This eight-pack of high-impedance injectors is engineered specifically for GM LS2 applications where OEM injector flow rates fall short of forced-induction or naturally aspirated builds pushing beyond 450 horsepower. Whether you're tuning a street LS, building a crate engine, or retrofitting a classic platform with modern LS architecture, these injectors deliver consistent atomization and metering under sustained load.

Each injector flows at 87.8 pounds per hour, a specification that bridges the gap between mild upgrades and serious boost applications without requiring extreme fuel pressure or ECU compensation headaches. The high-impedance design ensures compatibility with stock LS2 engine control modules and aftermarket tuning platforms alike, eliminating the need for external peak-and-hold drivers or relay modules on most installations. The EV6 / USCAR connector format is the industry standard for LS powerplants, guaranteeing plug-and-play integration with existing fuel rails and harnesses. Precision-ground internal orifices and multiple spray holes promote complete fuel atomization, reducing combustion temperature variance and supporting cleaner, more efficient combustion across the RPM spectrum.

Engine builders and performance enthusiasts running LS2 blocks—from Corvette, Pontiac GTO, and Cadillac CTS-V applications to standalone crate builds—benefit most from this eight-pack configuration, which covers the complete fuel system in a single purchase. Installation requires only fuel rail removal and simple snap-in connector engagement; no special tools or fuel system repressurization is necessary beyond standard LS engine work. These injectors are ideally suited for naturally aspirated builds up to approximately 550 wheel horsepower and moderate boost applications in the 600–700 range, depending on fuel grade and tuning strategy. Verify your fuel pressure regulator supports 43.5 PSI nominal operating pressure for optimal performance.
