FiTech Go Port EFI System, Small-Block Chevy, 200–550/550–1050 HP

Self-learning multi-port EFI system with aluminum intake, fuel rails and integrated ECU

Convert your carbureted small-block Chevrolet engine to electronic fuel injection with the FiTech Go Port EFI system. Designed to combine the precise fuel distribution of multi-port injection with simplified installation and tuning, this system positions eight fuel injectors directly in the intake runners to deliver fuel near each cylinder head port. Available in 200–550 horsepower and 550–1,050 horsepower configurations, each system features an aluminum intake manifold, high-flow fuel rails and a four-barrel throttle body with an integrated electronic control unit (ECU). The self-learning fuel management system automatically adjusts fuel delivery based on engine operating conditions, helping provide consistent throttle response and drivability. Each kit includes a complete aluminum intake manifold, eight fuel injectors, fuel rails, a 950 CFM throttle body, wiring harness, oxygen sensor and handheld calibration controller. The throttle body-mounted ECU incorporates MAP, throttle position and intake air temperature sensors, reducing the need for additional external wiring. The handheld controller allows initial setup and fuel calibration without requiring a laptop, while compatible ignition systems can utilize electronic timing control. A separate high-pressure EFI fuel delivery system and fuel pressure regulator are required for installation.
