    FiTech 93602 Details

    The retrofit fuel injection revolution has begun! FiTech is the leading name in EFI conversions for good reason, bringing not only economy to the market but simplicity through design. The switch to fuel injection has never been easier. FiTech’s technology is designed and developed using OEM level engineering and components. All throttle bodies have built-in computers and sensors, reducing the amount of wiring to route in your vehicle. You can run the system on only 4 wires and two sensors! The sensors are OEM style for proven reliability and easy replacement.

    Go EFI 2x4 Master Kit

    The Go Street EFI 400 HP kit is the most economical kit in the FiTech product line and is designed to work with most naturally aspirated small block street applications. It contains all of the same features as the other FiTech EFI kits, except for smaller, less costly fuel injectors (150-400 horsepower) and no timing control over the ignition system. This game-changing aftermarket fuel injection kit offers all of the latest technology and tuning software via a simple hand held controller. The self-learning ECU will continually adjust the fuel maps to increase efficiency and performance, while still allowing the user to adjust inputs on their own.

    A list of features for the FiTech 30003 Go Street EFI system:

    • Self-tuning EFI system - extreme self-learning for wide range super-fast dial in correction
    • Suitable for crate engines and mild performance engines
    • Pre-programmed with bolt-n-go technology for out of the box performance with no tuning required
    • EZ-tach input reads tach signal from coil, HEI, MSD/CDI and many other brand ignitions (no built-in timing control)
    • For non-boosted normally aspirated applications only
    • Wide band 4.2 O2 sensor
    • On board fuel pump driver
    • Annular discharge design
    • Hand-held tuning module for performance tuning
    • Single fan control and A/C input (kicks up idle)
    • FiTech flow-matched 62-lb/hr injectors
    • Attractive cast finish 
    • E85 compatible (30% reduction in HP capacity of fuel system and EFI)

    These fuel injection units are backed by a 1 year manufacturer warranty. Tuning and technical support is available through the phone and online support by the way of tech articles and emails. It's out-of-the-box compatible with everything from a 200 horsepower, small cubic inch factory original motor all the way to a brand new 350 HO crate motor. FiTech Go Street EFI will provide lower idle rpm, cleaner start up and crisp throttle response - features the best carb tuners in the world can’t match and only come with FiTech technology. Order today to join the golden age of fuel injection!

    FiTech Go-Spark CD Ignition

    FiTech EFI is excited to extend its ignition offerings with the new Go-Spark CD Ignition! The all-new Capacitive Discharge Ignition will deliver high powered sparks from idle to top rpm to improve the combustion event and power output of your engine.

    The Go-Spark CDI was designed for both EFI equipped or carbureted engines and features a microprocessor to manage the spark delivery. The ignition, which is assembled in the USA, 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. 

    The Go-Spark CDI is designed for 4, 6, and 8-cylinder engines equipped with a distributor. It accepts the trigger signal from an HEI, amplifier, points, or 2-wire non-magnetic pickup distributors. The tach output signal, which is also used to trigger a FiTech EFI system, is a 12-volt square wave signal that is divorced from other circuits to provide a clean, perfect signal.

    Go Fuel In-Tank Fuel Pump Module

    When it comes to converting to EFI, it’s important for the fuel pump to be installed in a cool area and what better place than in the gas tank itself. The pump is cooled by the fuel, it’s quieter plus there’s no chance of fuel starvation. To help ease the installation of an in-tank pump, this kit includes a new In-Tank Module assembly.

    This universal billet assembly can be used on tanks with a depth of 6” to 15”. The billet aluminum was designed with the supply and return ports in a parallel position to help route the fuel lines easily and evenly. The vent port is on the other side to ease routing the line near the fill tube. The two fuel ports are threaded to accept -6 AN O-ring boss fittings for a secure, leak-free connection.

    The cut-to-fit bracket secures a 340 LPH pump capable of providing fuel to 600 horsepower engines. To ensure clean fuel is pulled into the pump, two sizes of sock/filters are provided, a standard 11 square-inch design as well as a large, 35 square-inch version.

    • Easily install a 340 LPH pump into most fuel tanks
    • Adjustable for tanks from 6” to 15” of depth
    • Billet aluminum top features -6 fuel bosses
    • Low profile for improved clearance
    • Supplied with seals, lines and filter/socks
