What They Are: Holley Terminator EFI Systems

Why They’re Cool: Get a Terminator, add a 4150-style carbureted intake manifold and a compatible fuel delivery system, and you’ve got EFI in a weekend. The Holley Terminator EFI Engine Management Systems feature:

• ECU self-tunes instantly to deliver the perfect air/fuel mixture in real time for optimized fuel economy and power—no laptop required
• 950 cfm throttle body with computer-designed venturis—uses the same throttle body air entry area design used on Holley’s NASCAR Sprint Cup Series EFI
• Patent-pending annular discharge fuel ring for maximum flow and optimum fuel atomization—no restrictions or delay in fuel flow like booster designs
• 80 lb./hr. fuel injectors support from 250-600 horsepower
• Ignition timing control on engines with small cap HEI and Ford TFI distributors (requires adapter)
• Serviceable sensors integrated into throttle body and pre-wired for a simple one-click connection
• Connections for Ford, GM TH350, and 700R4 transmissions
• ECU can be easily updated to Holley HP ECU specs with a FREE online software download—Terminator ECU can then be used for LSX, boosted, nitrous, and many other applications
• Trouble-free performance with today's fuels including ethanol—eliminate vapor lock and fuel varnish problems

The Terminator Systems come with MAP, oxygen, TPS, and IAT sensors, IAC motor, fuel rails, wiring harness, and handheld calibration module.
