-10% Dual Terminator Throttle Body  Injection System

We offer this complete dual Terminator kit because Holley does not.  They do offer the various components to do it, but you either end up buying the entire system ala carte (which is an expensive way to proceed) or you can buy a Terminator kit and the extra components you need (which leaves you with a $300 main harness you can't use.)  And, at that point, you're on your own to configure it to work as a 2x4 Terminator system.

You can take your pick of any of the five different color/style combinations (including the standard silver and gray throttle bodies) and get a complete turn-key 2x4-barrel throttle body EFI system, with or without electronic transmission control capability for the GM 4L60E-4L80E or the Ford 4R70W-4R75W transmissions.  Look at this Twin Terminator Throttle Body System we built for 547 cubic inch Ford FE motor making 800 horsepower.

These systems offer all of the features of the standard Terminator EFI System but with twin four-barrel throttle bodies.  We custom-build the main harness to include the connector for the 2x4 Injector Connector, powering the injectors on the second Terminator throttle body (included.)  We perform all of the setup so that the system will be ready for initial start-up when professionally installed.  And, as with all of our products, the customer will receive our famed technical support from before the sale, through the installation, and assistance for the indefinite future.

Note:  Professional dyno tuning is recommended for all twin Terminator systems.  Kit includes Holley USB Harness.  Software can be downloaded here.

This kit includes:

  • HP or Dominator Series ECU (based on your selection of transmission control)
  • Two Terminator throttle bodies with injectors (throttle body sensors in one throttle body only)
  • Two Stealth Terminator Fuel Line Assemblies (one per Stealth throttle body)
  • Terminator Main Harness (professionally reconfigured for use with 2x4 Injector Harness)
  • Terminator 2x4 Injector Harness
  • Power Harness
  • 3.5-inch Handheld Touchscreen Monitor
  • USB Harness
  • Holley Bosch O2 Sensor and Coolant Temperature Sensor
  • Complete hardware kit included in standard Terminator EFI System kit plus second base and air filter gaskets

The Twin Terminator system is built to order and, as such, special order terms apply. Please reference our Terms & Conditions for Special Orders.

What If I Already Have A Terminator EFI System?

If you've already got a Terminator EFI system and simply need a complete kit of the additional components necessary to add and reconfigure this as a twin throttle body setup we have that!

What About A Fuel System?

You may be aware that the standard Terminator EFI System is available with a master kit option that includes a fuel pump, filters, hose, and other components.  In most cases, this kit will be undersized for the kind of fuel flow and horsepower requirements of these twin Terminator throttle body systems.  Be sure to let us custom engineer a fuel system solution that will be perfect for your project's specific requirements.
