The Porsche 930 Turbo 3.3

The Porsche 930, better known as the Porsche 911 Turbo, is a sports car that was produced from 1974 to 1989 based on the Porsche 911. At its introduction, the vehicle was the fastest mass-produced sports car in Germany. The 930 was the first production sports car in which Porsche installed a turbocharger. It was Porsche's top model, initially offered only as a coupe, and from 1987 also in Targa and Cabriolet body versions. Many design elements of the 911 Turbo were adopted from the 911 Carrera RS 3.0. These included the front and rear fenders, which were again widened by around 50 mm compared with the 911 Carrera RS 2.7 and were necessary to accommodate wide tires on the light-alloy Fox wheels under the body. To reduce lift on the front and rear axles and increase driving stability at higher speeds, the car received a front and rear spoiler. The large and flat rear spoiler resembled a whale's tail and became the main distinguishing feature of the sports car. Despite the high engine output offered by the 911 Turbo 3.0, many customers wanted an even more powerful 911 sports car. Porsche responded and developed a more powerful vehicle based on the first Turbo in 1977. Called the 911 Turbo 3.3, the new car produced 221 kW (300 hp) at 5500 rpm. This was achieved by increasing the displacement from three to 3.3 liters, increasing the compression ratio of the six-cylinder boxer engine to 7 : 1 and additionally using an intercooler. The intercooler, which was used for the first time in a production vehicle, meant that more air mass entered the cylinders with the same compression by the turbocharger, because the specific volume decreases during cooling ("the air contracts"). At the same time, because of the lower temperature, compression can also be higher, since the tendency to knock increases with the temperature of the compressed gas. Only this improved internal cooling allowed an increase in compression. The new 930 continued to have a four-speed manual transmission, with a top speed of 260 km/h and acceleration from zero to 100 km/h in 5.3 seconds. Buyers in the U.S., Canada and Japan received the sports car in a slightly less powerful version with 195 kW (265 hp) because of the stricter emissions regulations there. Externally, the car remained almost unchanged from the predecessor model with its significantly wider front and rear fenders. The only difference between the two vehicles was the modified rear wing. While the rear wing of the Turbo 3.0 resembled a whale's tail, the 3.3-liter Turbo had a larger rear wing with a substructure to accommodate the intercooler. In addition, the surrounding rubber lip was raised at the edges to allow even more air to enter the engine compartment.

The Porsche 930 Turbo 3.3 offered here was completed in July 1979 at the factory for the US market, where it was delivered in March 1980 to its first owner Mr. Otto Divosta, a well-known builder in the USA. The special thing about this car is that it is one of the last 50 examples of the 930 Turbo that were built for the US market. In addition to a plaque in the interior, a contemporary certificate from Porsche also provides information about this. For more than 30 years the car remained in the possession of Otto Divosta, who exhibited the car exclusively in his collection without ever driving it. At the same time, however, the car always remains ready for use. In 2016, Divosta decides to sell his 930 Turbo after more than three decades. The new owner, also a fanatic Porsche collector and a good customer of ours, owns the car for the following 5 years before the purchase by our company takes place. We hand over this time capsule with an original mileage of 130 miles since delivery including a great customer service and fully operational to its future owner. Our sales staff will be happy to answer any detailed questions you may have. Please note that vehicle inspections are generally only possible by prior appointment.
