911 S Competition

CPR Classic is excited to offer this competition-prepared 1973 Porsche 911S Coupe with a unique Italian history.

This 1973 911S was ordered new at Viscardo Automobili in Bologna by Italian hillclimb and racing driver Eugenio "Ennio" Bonomelli. Upon delivery, Ennio commissioned a Group 3 conversion to the car as he intended to compete in Group 3 FIA events and the European Hill Climb Championship with the vehicle. Viscardo Automobili carried out the conversion in February of 1973. The option package included an 88-liter fuel tank, FIA-approved roll bar, a limited-slip differential, rear RS flares, front strut brace and mounts, and a competition exhaust. The car's original color combination was Light Ivory over a lightweight black vinyl interior.

Although the car's FIA race history is unavailable, it is believed that the car competed extensively in ACI hill climb events during 1974 and 1975, driven by Bonomelli and Vincenzo Cazzago.

In the late 2000s, the car underwent a full restoration by an Italian specialist before being imported to the United States. The decision was made to color change the vehicle from Light Ivory to Gulf Blue. The car's restoration was very comprehensive: the tub was media blasted to bare metal and any necessary metal work was performed prior to the tub receiving its lovely Gulf Blue refinish. The wiring harness was replaced along with new relays and fuse panels. The gauges were rebuilt, and the interior was finished in a lightweight trim.

During the restoration, the rear suspension was upgraded with adjustable torsion bars, a hollow rear anti-roll bar, poly-bronze trailing arm and spring plate bushings, sealed mono-ball joints for the trailing arms, and adjustable camber plates. The front suspension received low-friction control arm mounts, de-cambered ball joints, and a bump steer kit. The car currently sits on period-correct Minilite 7- and 8-inch wheels wrapped in Pirelli P7 rubber. (The car will be delivered with a brand new set of correct Pirelli tires in RS sizing).

Modern safety amenities were added, to include the modern bucket seat and contemporary racing harnesses, when the restoration was performed. The Italian shop that carried out the restoration also added a few flourishes such as the Rennline shifter and smugglers box cover that are currently installed. These items can be returned to factory original specifications at no additional cost if the new buyer prefers.

The engine was overhauled by an engine builder in Italy and was upgraded to 2.7L modified-RS spec with Bosch mechanical fuel injection and has a redline of 7900 RPMs. The 915 gearbox was rebuilt with taller 4th and 5th gears. The car is claimed to do 0-60MPH in 4.7 seconds with a top speed of 177MPH.

If you are in the market for a fast and raw early 911 that has very interesting provenance and is perfect for canyon driving or the occasional track day, this is a must consider 911.
