Specifications

Go EFI Classic Gold 650 HP EFI System With Master Kit Inline Fuel Delivery

If you prefer the restored or classic hot rod look, FiTech's Go EFI Classic Series should be your choice. You get the performance benefits of modern fuel injection, with the looks of a vintage carburetor--without the flooding, vapor lock, and cold start issues. And FiTech's master kits will also provide a fuel delivery option, allowing you to take your setup from carburetor to EFI all with one part number.

FiTech Go EFI Classic 650 hp system inline pump/regulator/Go-Spark fuel injection master kits package a gold or black Classic throttle body with an inline pump kit, a Go Fuel Tight Fit regulator with gauge for precise fuel pressure, and a Go-Spark CDI ignition for high-powered sparks that improve combustion and power output. Choose your preferred finish.

Go EFI Classic throttle body features FiTech's advanced self-tuning fuel metering technology and will support engines rated up to 650 hp. Thanks to the dual bolt pattern, the throttle body will easily bolt onto most intake manifolds and throttle linkages. The ECU of the Classic Series is compact and easy to mount out of sight to maintain a restored engine compartment, but you'll notice the fuel injection benefits every time you turn the key!

The fuel delivery system is an inline fuel pump kit supplied with FiTech's heavy-duty 255 lph external fuel pump suitable to support engines producing up to 600 hp. The kit includes 40 ft. of high-pressure fuel hose, two billet fuel filters, fittings, mounts, and clamps. The Go Fuel single output regulator can be adjusted from 30 to 70 psi, will support up to 1,000 hp, and is crafted from billet aluminum with -6 ORB ports along with a vacuum/boost port and includes gauge.

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.
