FiTech Go EFI 4 600 HP Master Kit with Force Fuel Mini & Go Spark CDI Box
Transform your carbureted engine with a complete, self-tuning throttle body injection system featuring integrated ignition timing control and under-hood surge fuel delivery.
Product Overview
The FiTech Go EFI 4 600 HP system (MPN 93551) is an all-inclusive self-tuning fuel injection solution engineered for 4-, 6-, and 8-cylinder engines delivering between 200 HP and 600 HP. Designed to bolt directly onto any standard 4-barrel 4150 intake manifold, this bright aluminum throttle body houses an onboard ECU, eliminating complex engine bay wiring and firewall routing.
This master kit includes the compact Force Fuel Mini surge tank, which utilises your existing low-pressure mechanical or electric fuel pump to supply a high-pressure 58 PSI feed via an internal 255 LPH pump. Additionally, the included FiTech Go Spark CDI ignition box ensures full multi-spark combustion energy from idle through high-RPM demands.
