FAST Fuel Injection EZ-EFI Kit

FAST (Fuel Air Spark Technology) – the company behind the EZ-EFI system – has been leading the electronic fuel injection market for over 10 years. There’s no doubt in my mind that you’ll have added confidence with a FAST fuel injection kit under your hood. These EFI conversion kits will give you the superior performance you’ve been looking for without making sacrifices in other areas like reliability or quality.

Not only have hardcore car enthusiasts been paying close attention to the growth of the electronic fuel injection conversion kit market, but so have other automotive companies. In 2001 FAST was acquired by COMP Performance Group – the same company that produces popular products such as Comp Cams, TCI Transmissions and ZEX Nitrous Oxide Systems.

If you own a carbureted vehicle with less than 650 horsepower (up to 1200 hp on EZ-EFI 2.0 systems), an EZ-EFI Self-Tuning Fuel Injection system could be just what you’re looking for. Not only is a kit like this easy to install but it is also simple to maintain. Once you’re up and running the system will tune itself as you drive to keep your car’s performance at the optimal levels.

The EZ-EFI Fuel Injection System from FAST will work with your original carb-style throttle linkage, OEM sensors and all ignition setups. This kit includes an ECU, wiring harness, fuel injectors, fuel pump kit and throttle body.

Also included in the kit is a Bosch wideband O2 sensor. This is an important piece of the EFI system because it will help your car self-tune itself with extremely accurate air-fuel readings.

Will it fit your car? Well, if it’s a naturally aspirated, gasoline engine then, yes, it will.


FAST designed this system to work seamlessly with any Holley-style throttle linkage and 4150 manifold bolt patterns. If you have a Holley 4-barrel carburetor, then the FAST fuel injection kit will be a perfect direct replacement – no exceptions.

It also comes with a limited lifetime warranty so you can rest assured that if you run into any problems (which I doubt you will), FAST will get you taken care of quickly.

One of the main concerns I hear from my readers is that EFI looks too complicated for them to install themselves. This could not be further from the truth.

It can be installed in an afternoon and no tuning experience is needed.

Plus, you don’t even need a laptop to get started. The color touch screen monitor included in the kit features a easy to understand Setup Wizard that walks you through the process.

Why buy a carb to EFI conversion kit in the first place? The main reason is reliability, with a close second going to performance.

Once you have an electronic fuel injection system installed, you no longer have to worry about jetting and re-jetting throughout the year. The system will continuously tune itself to give you the most power while improving fuel efficiency at the same time.

It’s no secret that chasing gremlins in a carbureted fuel system can be a long and frustrating process. If you’ve spent any time trying to adjust your fuel and air ratios, you’ll know that there are more fun things you could be doing with your weekends.

So, why not put an end to those frustrating projects once and for all with a FAST fuel injection kit?
