Fear not, fuel injection fans. FAST has just made it easier than ever to convert your engine from a carburetor to fuel injection with these FAST EZ-EFI self-tuning fuel injection systems. 
 

The most important feature is the self-tuning operation that does not require chasing components, expert tuning experience, or a laptop computer to tune. Simply hook them up, answer the basic Wizard setup questions on the included hand-held display, and the systems truly tune themselves. 
 

The FAST EZ-EFI self-tuning fuel injection systems are totally complete systems. They include the ECU, a wide-band oxygen sensor, a wiring harness, and the innovative new FAST 4150 throttle body. The throttle body delivers the total package approach for anyone with an existing 4150-type (square bore) intake manifold.

NOTE: This base kit requires a separate purchase of a fuel pump capable of 450 LPH and 70 PSI and adjustable pressure regulator capable of  approx 30-70 psi it does not include an ignition system or other
