FiTech Go EFI 2 Barrel Carburetor Style 400HP Fuel Injection System

The FiTech Go EFI 2-Barrel 400HP Fuel Injection System (Classic Carburetor Gold) is an entry-level, cost-effective throttle body injection (TBI) setup designed to replace traditional 2-barrel carburetors on small-block V8s and inline 6-cylinder engines. Engineered for street rods, classic cruisers, and mild performance engines, this self-tuning system delivers reliable cold starts, crisp throttle response, and improved fuel economy without complex computer tuning or laptop programming.

System Architecture & Performance Highlights

• Classic Carburetor Gold Finish: Features a classic gold die-cast throttle body finish that replicates the vintage look of traditional brass-finished carburetors while housing modern high-pressure fuel injectors and sensors.

• Streamlined Self-Tuning Operation: Strips away high-end racing adjustments in favor of basic, highly effective self-learning parameters that continuously calibrate air/fuel ratios based on real-time exhaust feedback.

• Integral ECU Design: The ECU is mounted directly on the throttle body assembly, eliminating the need to mount an external computer inside the cab or run complex wiring through the firewall.

• Complete Sensor Package: Supplied with a Bosch wideband oxygen sensor, coolant temperature sensor, handheld controller, and windshield suction mount for immediate installation and live engine monitoring.

• 400HP Capacity: Ideal for naturally aspirated engines generating up to 400 horsepower, serving as a direct drop-in replacement for standard 2-barrel carburetors or 4-barrel intakes using a 2-to-4-barrel adapter plate.

Technical Specification Matrix

Installation & Fuel System Recommendations

• Fuel Delivery Requirement: This kit does not include a fuel pump or fuel lines. It requires an EFI-grade high-pressure fuel supply delivering 58 PSI (such as an external inline pump, an in-tank fuel pump retrofit kit, or a fuel command center module).

• Manifold Mounting: Mounts directly to standard 2-barrel intake manifolds. To install on a standard 4-barrel intake manifold, use a standard 2-barrel to 4-barrel carburetor adapter plate.

• Wideband O2 Installation: Weld the included wideband O2 sensor bung into the exhaust pipe at least 18 inches downstream of the cylinder head exhaust ports, angled slightly upward (at least 10 degrees above horizontal) to prevent moisture buildup on the sensor tip.
