1973 Porsche 9146 Silver Metallic

Finished in Silver llic paint, this 1973 Porsche 914 is the subject of an engine swap.

The brakes, transmission, engine oil system, and exhaust were upgraded to accommodate the increased output of the 3.0-liter powerplant, which was converted to carburetion from fuel injection to approximate the factory’s 914/6 configuration. Upon completion of the swap, Mayeur is quoted as having said, “This is one of the nicest driving modified 914’s we have had in our shop.”

The seller states this vehicle will be sold on a clean New title in his name. An extensive build diary is included outlining the work performed to convert this Silver llic 1—into a 914/6. The six-cylinder conversion is documented to have started in April 2017 and finished in July 2017. By all appearances, every effort was made to approximate the configuration of the original 914/6, albeit with a more powerful engine than the original used. sed on the specs of the 1983 911SC engine fitted to this car, the Mayeur conversion enjoys an advantage of roughly 49 horsepower and 44 lb-ft of torque over the original 914/6. n the 914’s curb weight of just over 2,000 pounds, this should be more than enough to motivate the ga-topped mid-engine Porsche quite vigorously.
