FiTech Go EFI 2x4 625 HP System Force Fuel/Go Spark Fuel Injection Master Kits

FiTech Go EFI 2x4 625 hp system Force Fuel/Go Spark fuel injection master kits are inclusive EFI kits with fuel delivery solutions, plus an upgrade to high-powered sparks for improved combustion and power output. In these master kits, FiTech mates their 2x4 TBIs with one of their Force Fuel kits that allows you to keep the stock pump to feed the Force Fuel reservoir, while its internal pump provides high pressure to the EFI system. The throttle bodies are offered in matte black or bright aluminum finishes. Choose the master kit with your preferred finish and Force fuel delivery solution.

Go EFI 2x4 625 hp system lets everyone know you mean business with a pair of 4-barrels crowned atop your engine! The 2x4 is supplied with two throttle bodies, one with the brains and integral ECU, the other with the brawn. Both bodies feature four injectors and will support up to 625 hp (naturally aspirated). The system is supplied with two throttle bodies, handheld controller, cable and windshield mount, throttle body vehicle side harness, WBO2 sensor, bung kit, coolant sensor, gasket, mini USB cable, instructions, and warranty information.

Go-Spark CDI ignition produces a series of multiple sparks below 2,500 rpm to improve starting, idle quality, and throttle response. At higher rpm, the CD technology continues to deliver full energy sparks through racing rpm to ensure complete combustion of the fuel mixture. Designed for 4-, 6-, and 8-cylinder engines equipped with a distributor, Go-Spark accepts the trigger signal from an HEI, amplifier, points, or 2-wire non-magnetic pickup distributors.

Force Fuel delivery options:

Go Fuel Force Fuel supports the fuel demands of an 800 hp engine on gas using an internal 340 lph pump. The reservoir holds a .5 gallon of fuel to submerge an internal electric fuel pump, keeping it cool with no chance of fuel starvation. An internal regulator keeps the pressure at a consistent 58 psi, ideal for reliable EFI performance. Force Fuel kit is supplied with 5 ft. of high-pressure fuel hose, 10-micron fuel filter, AN fittings, return line fitting bung, and a liquid filled gauge.

Go Fuel Mini Force Fuel supports fuel demands up to 600 hp. These smaller versions are ideal for cramped engine compartments, can be installed in four positions, and feature a reservoir with an efficient 255 lph pump with an internal regulator delivering a consistent 58 psi for your EFI system. The Mini is supplied with a high-pressure fuel hose, AN fittings, return line fitting bung, and a liquid filled gauge.
