Custom Fuel Injection Systems for Classic Cars
Classic cars capture the spirit of a bygone era—but outdated carburetors often make them difficult to start, inefficient, and less reliable on today’s roads. At Greg’s Classics in Durham, NC, we specialize in custom fuel injection conversions that bring modern drivability and performance to your vintage ride without compromising its timeless character.


Why Upgrade to Fuel Injection?
Carburetors may have been standard decades ago, but today’s fuel injection systems offer significant advantages. Reliability improves dramatically, eliminating cold-start issues and constant adjustments. Fuel efficiency increases because modern systems deliver fuel precisely, reducing waste and saving you money at the pump. Performance is also enhanced, giving smoother throttle response, more consistent power, and optimized air-fuel ratios for every drive. Perhaps most importantly, maintenance demands drop considerably, meaning you can spend less time tinkering and more time enjoying your car.
Our Custom Fuel Injection Services
At Greg’s Classics, we design and install fuel injection systems tailored to your vehicle and driving goals. We handle complete carburetor-to-EFI conversions for smooth, reliable performance, along with throttle-body injection setups that maintain a classic look at a lower cost.

Every installation includes proper tuning and calibration, from ECU programming to dyno adjustments, ensuring your engine runs exactly the way it should. For customers planning engine swaps—whether LS, Coyote, HEMI, or other platforms—we integrate modern fuel injection seamlessly into the build.
