    FiTech 93603 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 6 Power Adder Kit

    FiTech recognized the need for a fuel injection unit that is compatible in nitrous and boosted applications. They understand that not everyone has a mild weekend cruiser tucked away in the shop. The Fitech Go EFI Power Adder 600HP Kit is just what you need for your boosted or nitrous powered engine. This system can be used in blow thru turbo, blower, or roots style supercharger configurations, capable of handling 25 lbs of boost. Can also be used in single stage wet nitrous systems with the ability to control A/F mixtures and ignition timing. Features Nitrous and Boost timing retard functions, making this a perfect fuel injection system to add to your high horsepower engine.

    All the same standard features of FiTech fuel injection with the added control over boosted and nitrous applications. This system also works well in naturally aspirated applications, in case you have big plans for the future! FiTech has revolutionized the aftermarket fuel injection industry by providing affordable fuel injection kits for all your needs - From a mild 350 small block to a big cubic inch turbo motor, you can trust that FiTech has just the right set up for your needs!

    • Boost and Nitrous timing retard strategies 
    • 2 fan control (can set at separate temperatures)   
    • Air-conditioning idle speed input kick up  
    • Advanced hand Held Tuning Mode Enabled  
    • Pro Laptop Software, complete tuning for professional tuners    
    • You also get the standard features included in ALL of the Go EFI Systems: 
    • (4) Hi-Flow 600 HP injectors  
    • Initial setup is quick and easy. Simple touch screen selections get you up and running in minutes  
    • Self-tuning After startup the ECU immediately takes over and provides your vehicle with an optimum tune   
    • Basic install can be done with just 4 wires and 2 sensors to install   
    • The ECU is mounted on the throttle body so there is NO external boxes or harnesses to clutter up your engine compartment or under dash. This saves you a huge amount of time and keeps things simple and neat   
    • Uses a Bosch 4.2 wide band O2 sensor while all other sensors are easily replaceable GM style parts

    • Ignition timing can be controlled and adjusted on the fly from your touch screen controller   
    • Air Fuel ratios can be optimized on the fly as you drive! Try that with your Carb  
    • Will work with CDI box but not required to control timing  
    • Built in Fuel pressure regulator. No extra regulator to mount on your fire wall   
    • Use of ignition timing control is optional and not required   
    • Ignition timing control does not learn, and requires synchronizing distributor to engine with a timing light

    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
