This 1989 Porsche 911 (930) Turbo 3.3 is a very nice example from the last year of production 1989 – the ultimate version of the classic Porsche 930 Turbo.
Introduced by Porsche in 1975, the 930 Turbo was a revolution and immediately became an icon. The Turbo was the top model of Porsche and both extremely powerful and very well equipped. With its significantly wider body, wide rims and the striking Turbo spoiler, it was instantly recognizable.
It was the first production sports car in which Porsche installed a turbocharger and the fastest production car on German roads at the time of its introduction. With its high power output of 260 PS (191 kW) and comparatively low weight, it offered performance that was previously known almost only from pure racing cars.
At the end of 1979 a completely newly developed turbo came onto the market with the new 3.3 liter turbo, which now reached the magical figure of 300 PS (220 kW), thus satisfying the wishes of the power-hungry clientele. The new “Super-Turbo” was the result of long development work in order to make the increase in power possible on the one hand, but also to adjust the car technically to the higher performance. The increase of the cubic capacity to 3,298 cc made a number of new components such as crankshaft, connecting rod, piston and cylinder as well as oil pump necessary. In addition, the Turbo 3.3 is the first production engine with an intercooler. By reducing the temperature, more air mass is available in the supplied air for the same volume. Thus, more fuel could be burned and the efficiency increased.
The optimized shape and angle of the new spoiler provided more downforce and thus better power transmission of the rear wheels with the same air resistance. At the same time, the new design with its raised edges ensured better flow to the new intercooler.
The brake system was also improved on the 3.3 Turbo: On the one hand, thicker brake discs at the front and rear allowed larger ventilation channels in the discs. In addition, the brake discs were now perforated, which made them more responsive on wet roads.
The 3.3 Turbo was built from 1977 to 1988 without major modifications. It was not until model year 1989 that the ultimate evolutionary step of the Porsche 930 Turbo was launched – the 89 Turbo.
The model year 1989 was the last model year of the so-called “G-model” of the Porsche 911, and in the same year the successor 964 came on the market.
For this last model year, Porsche equipped the 930 Turbo with the modern and reinforced 5-speed G50 transmission and also fitted the car with a hydraulic clutch. These changes significantly improved the handling of the 930 Turbo once again. The additional gear allowed smaller rev intervals which enables the turbo charger to build up pressure more quickly. The hydraulic clutch can be operated with significantly less power and also with greater precision, which makes for greater comfort and better starts.
Driving performance is also improved by the new transmission.
Chassis tuning has also been thoroughly improved with larger torsion bars on the rear axle, modified anti-roll bars and harder-tuned shock absorbers for the 89er.
The car we are offering was first delivered to the USA and is one of only 540 1989 Porsche 930 turbo Cabriolets built for the USA. For the rest of the world, only another 184 turbo convertibles were produced.
This car is one of the very last cars built with a very high chassis number among the last 15 cars of this type built.
Since also from the successor 964 Turbo only 6 Cabriolets and from the following 993 Turbo also only 14 Cabriolets were built, an air-cooled Porsche 911 Turbo Cabriolet is an extremely rare thing.
The new price of a 930 Turbo Cabriolet in 1989 was 155,000 DM, which was 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 PS (206 kW) as standard. Until model year 1986 the 930 turbo cars in the USA only had 265 PS (195 kW) and then received the more powerful engine which is also installed in this model.
The color combination is solid black (A1A1) combined with black leather.
The original service booklet is not available, but through the present Carfax Report with 12 entries, the mileage is well documented and is only just over 30,000 miles or just under 50,000 km. According to the available papers and conversations with the previous American owners, the car had only 2 owners in the USA. The first owner bought the car in California and then moved to Aspen, Colorado in 1996. At 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 that time the car had a mileage of 27,713 miles.
In 2007 the current German owner bought the car in the USA with 28,272 miles and imported it to Germany. The car is registered in Germany as a historic vehicle.
The car is in a very well-kept condition with a very nice, nearly new original interior.
The paintwork is to a large extent still original in a remarkable condition, especially for a 33 year old non-metallic black paint
The car has a stainless steel sport exhaust and a larger Andial intercooler. The turbocharger is the original KKK turbocharger from Porsche.
Beside the original soft top there is a complete tarpaulin to cover the interior.
