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
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
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.
