FiTech Mean Street EFI 800 HP Master Kit w/ Force Fuel & CDI Box
Complete self-tuning 800 HP throttle body fuel injection conversion kit with integrated Force Fuel delivery surge tank and Go-Spark CDI ignition box in a matte black finish.
Product Overview
The FiTech Mean Street EFI Master Kit (MPN: 93508) provides an all-inclusive fuel injection retrofit solution engineered for high-performance engines producing up to 800 HP. Featuring an 8-injector 4-barrel square bore throttle body finished in matte black, this self-contained system places the ECU directly on the throttle body to eliminate cumbersome under-dash wiring.
This master package includes FiTech’s Force Fuel delivery system, which mounts under the hood and connects to your original mechanical or low-pressure fuel pump, creating a high-pressure reservoir without dropping or replacing your fuel tank. Additionally, the included Go-Spark CDI box ensures powerful capacitive discharge spark management for maximum ignition performance.
