GM LS Retro-LS 650 HP Master EFI Kit, Gold, with Force Fuel by FiTech®

Carburetor-style gold EFI adds LS fuel, ignition and transmission control with an underhood fuel supply.

This FiTech® Retro-LS master kit mounts a classic gold throttle body on a carburetor-style LS intake and supports engines up to 650 HP. Four 80-lb injectors feed fuel through an annular-discharge design with semi-sequential control. The ECU supplies ignition-timing control, accepts factory knock-sensor signals and works with 24x/58x crank signals. A terminated LS harness simplifies connections, and the controller can manage shift points and behavior on compatible 4L60E/65E/80E transmissions. Setup uses the handheld rather than a laptop. The EFI package includes the ECU, controller and windshield mount, dual wideband oxygen sensors, bung kits, gasket and mini USB cable. Force Fuel adds an underhood reservoir, submerged 340 LPH pump, built-in regulator, 5 feet of high-pressure hose, -6 AN fittings and a serviceable 10-micron filter. The existing pump feeds the reservoir; a return connection to the tank remains necessary.
