Classic 4x4s were built tough, but their carburetors were never designed for modern driving. Hard starts, poor fuel economy, and temperamental performance come with the territory. At Legacy Motorworks, we solve these issues with EFI (Electronic Fuel Injection) conversions, bringing vintage engines into the modern era without losing their character.
Our EFI conversions replace old carburetors with state-of-the-art fuel injection systems. The result is smoother cold starts, consistent throttle response, improved fuel efficiency, and greater reliability in all conditions—whether climbing mountain trails or idling in city traffic. Each installation is fully integrated with the vehicle’s wiring, sensors, and fuel delivery system, ensuring seamless operation and long-term dependability.
From Toyota Land Cruisers and Land Rover Defenders to Range Rover Classics, Ford Broncos, and vintage Jeeps, we’ve upgraded them all. Many clients choose to pair EFI with a full engine rebuild, giving their 4x4 a reborn heart that is both true to its roots and fit for decades of adventure.
