Description

The FiTech 37854 Go Port EFI System offers a streamlined solution for upgrading your Chevy Small Block Gen 1 engine to electronic fuel injection. It ingeniously merges the user-friendly installation of throttle body EFI with the superior fuel delivery precision of a port-style system. This kit is engineered for engines producing between 200 and 550 horsepower, making it suitable for a wide range of performance applications, from street-driven classics to crate engines. At its core, this system features a high-flow FiTech throttle body, complete with an integrated ECU for a compact and efficient setup. This is paired with a durable aluminum intake manifold and high-flow injectors mounted in robust fuel rails, ensuring optimal fuel atomization and distribution directly to each cylinder. The system employs speed-density (MAP-N) metering for accurate fuel calculations and boasts compatibility with timing control for enhanced engine management. The included components ensure a comprehensive upgrade path, including a calibration module, wiring harness, oxygen sensor, MAP sensor, IAT sensor, and TPS sensor. The throttle body is designed with a standard 4-barrel square bore flange and 44mm venturis, capable of handling up to 950 cfm of airflow. This system supports various fuel types, including gasoline, alcohol, methanol, and flex fuels, offering flexibility for different performance goals. While the ECU and intake manifold are included, a separate fuel pump, fuel pressure regulator, and transmission controller are not part of this kit and will need to be sourced independently. Installation involves connecting the necessary fuel lines and wiring, with resources like installation guides and instructional videos available from FiTech to assist. This kit is specifically designed for Chevy Small Block Gen 1 engines and is not a universal fit. It is important to ensure compatibility with your specific engine configuration before purchase.
