FiTech Retro LS TBI 650 HP System Force Fuel Injection Master Kits

FiTech Retro LS TBI 650 hp system Force fuel injection master kits deliver old school looks and modern EFI performance for your hot rod.

These kits feature a FiTech classic carburetor-gold throttle body with transmission control and a pre-terminated wiring harness with specific LS engine sensors, including the factory knock sensors to complement the built-in timing control. The remote ECU can control the transmission shift points and characteristics of the popular 4L60/65/80E transmissions. No laptop is required, and the system will work on 24x or 58x cam sensors. Also supplied with the Retro LS TBI is a handheld touch screen controller, cable and windshield mount, WBO2 sensor, bung kit, gaskets, mini USB cable, instructions, and warranty info.

FiTech master kits provide a fuel delivery system and in these kits you'll have either a Go Fuel Force Fuel or Mini Force system. The Force Fuel supports the demands of an 800 hp engine on gas and features a 1/2 gallon reservoir, an internal 340 lph pump with a serviceable 10 micron fuel filter, and an internal regulator that keeps the pressure at a consistent 58 psi, ideal for reliable EFI performance. The Mini Force is great for cramped engine compartments and supports up to 600 hp. It is equipped with an efficient 255 lph pump and an internal regulator. Both systems are supplied with high-pressure fuel hose, return line fitting bung, and a liquid-filled gauge. Choose the FiTech Retro LS master kit with your preferred fuel delivery system.
