It was the first production sports car in which Porsche installed a turbocharger and when it appeared it was the fastest series-produced car on German roads. With a high output of 260 hp (191 kW) and a comparatively low weight, it offered driving performance that was previously only known from pure racing cars.
At the end of 1979, the new 3.3 liter turbo, a completely newly developed turbo, came onto the market, which now reached the magic figure of 300 PS (220 kW) and thus served the wishes of performance-hungry customers. The new “Super-Turbo” was the result of long development work, on the one hand to enable the increase in performance, but also to adapt the car as a whole to the higher performance technically. The increase in displacement to 3,298 cc made a number of new components such as the crankshaft, connecting rods, pistons and cylinders as well as the oil pump necessary. In addition, the Turbo 3.3 is the first series engine whose charge air is pre-cooled. By reducing the temperature, there is more air mass in the supplied air with the same volume. In this way, more fuel could be burned and the efficiency increased.
The optimized shape and angle of attack of the new spoiler ensured less lift and thus better power transmission to the rear wheels with the same air resistance. At the same time, the new design with the raised edges ensured better flow to the new intercooler.
The braking system has also been improved on the 3.3 Turbo: On the one hand, thicker brake discs at the front and rear allow larger ventilation channels in the discs. In addition, the brake discs were now perforated, which is why they responded better even when wet.
The 3.3 Turbo was built from 1977 to 1988 without major changes. It was not until model year 1989 that the ultimate evolutionary stage of the Porsche 930 Turbo came on the market - the 89 Turbo.
The model year 1989 was the last model year of the so-called "G-model" of the Porsche 911. In the same year the successor 964 came onto the market.
For this last model year, Porsche equipped the 930 Turbo with the modern and reinforced 5-speed G50 transmission and also equipped the car with a hydraulic clutch. These changes significantly improved the handling of the 930 Turbo. The now more closely stepped transmission leads to smaller speed jumps so that the turbocharger can build up pressure more quickly. The hydraulic clutch can be operated with significantly less force and also with more precision, which enables more comfort and better starts.
The driving performance also improved thanks to the new transmission.
The chassis set-up has also been thoroughly improved with larger torsion bars on the rear axle, modified stabilizers and harder-tuned shock absorbers for the 89er.
The car was delivered new to the USA, making it one of only 540 Porsche 930 turbo convertibles built for the USA in 1989. Only 184 turbo convertibles were then produced for the rest of the world.
This car is one of the very last vehicles built with a very high chassis number among the last 15 vehicles of this type built.
Since only 6 convertibles were built from the successor 964 Turbo and only 14 convertibles from the following 993 Turbo, an air-cooled Porsche 911 Turbo Cabriolet is an extremely rare proposition.
The new price of a 930 Turbo Cabriolet in 1989 was 155,000 DM, 22,000 DM over a 930 Turbo Coupé and 14,500 DM over a 930 Turbo Targa.
As a late US model, this car has the 930/68 engine with 282 hp (206 kW) as standard. Up to model year 1986, the 930 turbos in the USA had only 265 hp (195 kW) and were then given the more powerful engine that is also installed in this example.
The color combination is plain black (A1A1) combined with black leather.
The original checkbook is not available, but the Carfax Report with 12 entries clearly documents the mileage and is only just over 30,000 miles or just under 50,000 km. According to the available papers and discussions with the previous American owners, the car only had 2 owners in the USA. The first owner bought the car in California and then moved to Aspen, Colorado in 1996. In the first emissions test in Aspen in 1996, the car had run 21,251 miles. In 2000 he sold the car back to California to the second owner from Santa Barbara. In 2003 he sold the car back to the first owner from Aspen. At the time the car had run 27,713 miles.
In 2007 the current German owner bought the car with 28,272 miles and imported it into Germany. The car has a German H approval.
The car is in a very neat condition with a very nice, almost new original interior.
Most of the paintwork is still original and in remarkable condition for a 33 year old black plain paint.
A stainless steel sports exhaust and a larger Andial intercooler are installed in the car. The turbocharger is the original KKK turbocharger from Porsche.
In addition to the original hood, there is also a complete tarpaulin to cover the interior.
The car can be viewed by arrangement. A lifting platform is of course also available for you.
