• Porsche 930

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 launch, the vehicle was the fastest mass-produced sports car in Germany. The 930 was the first production sports car in the Porsche einbaute a turbocharger. He was the top model of Porsche, which was initially offered only as a coupe, since 1987 also in the following body Targa and Cabriolet.

The related racing models Porsche 934 and Porsche 935 have been used successfully in groups 4 and 5 of the World Sportscar Championship and also in Division 1 of the German Racing Championship.

For the valid from 1976 Group 4 of the World Sportscar Championship Porsche was planning a lightweight 911. This race car should be equipped with a turbocharger, the six-cylinder boxer engine of the Porsche 911 Carrera RS 3.0. Short-term changes in the regulations of the FIA, in which the vehicle’s minimum weight has been lifted, reduced the odds of the future race car. Therefore Porsche stopped the development of the vehicle.

The recovered with the racing car development experience in turbo engines used Porsche to design a sports car, the approach presented to the competition from Ferrari and Lamborghini. The car should be used as top model with the design, engine performance and the facilities close this gap. Because of its many, especially in the motor, comprehensive changes to the standard 911ern the car was given a separate type number with the 930.

Many design elements of the 911 Turbo 3.0 were taken from the 911 Carrera RS. These included the 2.7 again to accommodate over the 911 Carrera RS by about 50 mm widened front and rear fenders, which were necessary wide tires on light metal rims fox under the body. To reduce lift on the front and rear axle and to increase the stability at higher speeds, the car received a front and rear spoiler. The large and flat rear spoiler resembled a Walschwanzflosse and was the main distinguishing feature of the sports car.

For the Porsche 930 since its introduction over the years different paint schemes were offered. In addition to the extra free serial Unilacken there were metallic finishes, so-called spot colors.

The Porsche 911 Turbo was introduced in October 1974 at the Paris Motor Show for the first time to a public audience. The new sports car fell on his style similar to racing car body design and equipped with an exhaust gas turbocharger 3-liter boxer engine. Although the automotive industry had not yet recovered at the time of the oil crisis, the car received a positive review.

As standard, the car was with 185/70-VR-15-Reifen on 7J x 15 wheels front and 215/60-VR-15-Reifen on 8J x 15 wheels shipped back. As a special request could instead tires with 205/50 VR 15 front and 225/50 VR 15 ordered back on the same rim width. The windows were tinted green all around, and the rear and windshield could be heated. The rear window wiper, the wiper interval switch for the front windscreen wipers and Headlight cleaning system made for clear view and increased driving safety. In order to make as comfortable as possible, traveling by Porsche, the car had an automatically regulated heating, electric windows, electrically adjustable front seats. An optional air conditioning (refrigeration unit) for 2400 DM was available.

The interior consisted of a leather-fabric combination of the front and rear seats and door panels. Another distinguishing feature of the 911ern with naturally aspirated engines had the 930 on the left rear side of the rear seat back an embroidered Turbo Lettering. The standard was a three-spoke leather steering wheel. Behind it were as common in the 911, the five round instruments with fuel and oil level indicator, temperature and oil pressure gauge, tachometer with Boost Gauge (from 1977), speed and mileage display and analog quartz watch.

1976 Turbo was all other Porsche models from hot-dip galvanized steel sheets produced as and, for a period of six years against rust perforation of the floor assembly. The equipment scope was expanded to include electrically adjustable and heated door mirrors. The wheels with Pirelli P7 tires with 205/50 VR 15 front and 225/50 VR 15 back on forged aluminum wheels in the dimensions 7J x 15 front and 8J x 15 rear were now standard equipment.

The turbo was first sold in the year in the U.S. and Canada, due to stricter emissions regulations but with a slightly lower engine output of 180 kW (245hp). The Porsche Turbo enjoyed at its launch in the U.S. and Canada great popularity. 1976 520 copies of the 911 Turbo have already been exported to the USA.

In its last year of production of the 930 experienced a number of technical improvements and upgrades. The two fuel pumps were replaced with improved versions. The fuel filter and the fuel pressure accumulator are also changed. It was now at the front axle instead of a stabilizer having a stabilizer 18 mm with 20 mm diameter, whereby the driving stability is further increased. The car had 1977 standard with 16-inch wheels 205/55-VR-16-Reifen on 7J x 16 wheels front and 225/50-VR-16-Reifen on 8J x 16 rims.

So that the driver could monitor the boost pressure of the turbocharger, in the rev counter a pressure gauge was installed and for the increased comfort preferences, Porsche delivered standard with a coupling means and a brake booster. A new center console, the illuminated central ventilation regulation and the warning display for hand brake and driver’s safety belt evaluated the sports car to continue. Inside, the car received new materials and new exterior paint colors Selection.

The combination of luxury and performance that offered the 911 Turbo 3.0, enthusiastic buyers had expected more than Porsche. For the planned homologation as a Group 4 car in the sports car world championship until 1976 had a total of 400 vehicles to be produced. Instead of the planned on a small scale in 1000 copies by the end of 1977 end 2876 cars were built. The following year, replaced the more powerful successor model Porsche 911 Turbo 3.3 from the car.

Despite the high engine power, the 911 Turbo 3.0 offered, many customers wanted an even more powerful 911 sports car. Porsche responded and developed in 1977 based on the first turbos a more powerful vehicle. The new 911 Turbo 3.3-called car made 221 kW (300hp) at an engine speed of 5500 rpm. This was achieved by increasing the displacement from three to 3.3 liters, an increase in the compaction of the Six-cylinder boxer engine at 7: 1 and the additional use of an intercooler. Through the intercooler first time on a production vehicle was reached that for the same compression by the turbocharger came in more air into the cylinders, because the cooling takes the specific volume from ( Draws air together). At the same time due to the lower temperature, the compression be higher, because the tendency to knock increases with the temperature of the compressed gas. It is this improved internal cooling allowed for an increase in the compression. The new 930 still had a four-speed manual transmission, with a top speed of 260km/h and acceleration from zero to 100km/h in 5.3 secondscould be reached.

Buyers in the U.S., Canada and Japan got the sports car because of the stricter emissions regulations there in a slightly less powerful version with 195 kW (265hp). Externally, the car remained almost unchanged with its front and rear fenders widened sharply compared to the previous model. Only on the modified rear wing, both vehicles were indistinguishable. Similar to this in the Turbo 3.0 yet Walschwanzflosse, had the 3.3-liter turbo on the other hand, so that the intercooler was space including a larger rear wing with base. In addition, the circumferential rubber lip was pulled up at the edges, so to usher in even more air into the engine compartment can.

As standard, the Turbo with 205/55-VR-16-Reifen was on 7J x 16 wheels front and 225/50-VR-16-Reifen equipped on 8J x 16 rear rims. The brake system of the increased engine performance has been adjusted. The internally ventilated and perforated disc brakes were now fitted over the 3-liter turbo thicker and with larger ventilation channels. The four-piston aluminum brake callipers were derived from the Porsche 917 and had for better heat dissipation fins.

From 1984, the buyer had the opportunity through a plant capacity increase (WLS) by 22 kW to raise the standard engine power (30hp). The modified engine generated at 5750 rpm now 243 kW (330hp). These had provided, and are incorporated in the front apron, an oil cooler, among other things, the exhaust system with the left and right sides brought out twin tailpipes. The oil cooler was a visible means cooler with a modified front spoiler or as additional hidden behind the radiator be ordered at Serienbugschürze attributable fog lamps. All vehicles with WLS were delivered solely to the rear wheels combined amended 245/45 VR 16 on 9J x 16 wheels instead of 225/50 VR 16 on 8J x 16 rims. A year later, this vehicle belonged tires as standard. The changes were only about the Porsche special request program or Porsche Exclusive program be ordered.

Many buyers with a 911 naturally aspirated engine, the appearance of the Porsche 911 Turbo wanted for her car. This conversion took place from c.1981 to later in the repair department at Porsche. From 1984, the conversion could be ordered as optional equipment request directly from the factory. This factory Turbo look (WTL) contained, in addition to the general body of the turbos also its running gear with the brake system. Another exclusively offered for the turbo ordering option was the so-called low-rise building in which the 930 could specifically get the car front look of the Porsche 935 race car.

After eleven years and 17 381 copies produced, the production of the Porsche 911 Turbo 3.3 was set. His successor was produced from 1990 Porsche 964 Turbo.

Early 1980s were modifications to the 930, with which it has had the front look of the race car Porsche 935, particularly in the U.S. very popular. Porsche therefore offered from 1981 to a flat-conversion for the turbo models. This conversion was not available as additional equipment as standard, but was carried out subsequently via the special order program in the Porsche Repair Crafts department.

The modification consisted of various elements that had to be ordered separately. The full flat-rebuild included the actual flat car front in 935 optic with the recessed in the fenders pop-up headlights and the front apron centrally positioned engine oil cooler, the Radhausentlüftungen in the front fenders, the side skirts and the air inlet holes on the rear fenders. Initially, it was next to the car front with the Pop-up headlights also a version available where the headlights were integrated into the front spoiler. In this embodiment, the repair department represented only 58 copies ago. Of the tags with pop-up headlights in the fenders 204 vehicles emerged in subsequent hand. From 1984, the flat belonged to the special features list. The turbo flat was produced as direct from the factory in the regular production, a total of 686 vehicles in series production within the Porsche Exclusive program. The conversion costs amounted depending on the scope of the renovation in 1985 to up to 27,500 DM Combined buyer turbo flat with an increase in output at the factory, the purchase price of the 3.3-liter turbo nearly doubled.

Since the conversion components even without the flat front were sold individually, many vehicles were partially ordered with the air inlet holes on the rear fenders without additional body changes.

Meanwhile, an original Porsche built turbocharged 3.3-rise building is one of the very rare 911 models and reached 2012 in good to very good condition Price 80000-100000 euros.

The Porsche 930 was produced with this Porsche’s internal designation from 1974 to 1989 in the following versions:

1 WLS stands for plant performance improvement

In the United States, Canada and Japan had the 3-liter turbo only an output of 180 kW (245hp) and the 3.3-liter turbo, a reduced initial capacity of 195 kW (265hp) and 207 kW from 1986 by (282hp).

The Porsche 930 was produced in the following quantities per model year.

Although the Porsche 930 was in contrast to the racing models 934 and 935 not specifically designed for motor sports, individual racing teams 1977-1984 put him in some races in the World Sportscar Championship. There, the vehicles started in the group GT and in the years 1983 and 1984 in Group B also in the 24-hour race at Le Mans. There, reached the 930 as the best placement in 1983 to eleventh place in the overall standings and the Class win in Group B.

As a best finish at the World Sports Car Championship the car at the 1000km race at the Nürburgring in 1983 was driven by the team Edgar Dören to seventh place in the overall standings and class win in Group B.

The group had B-930 engine power of 269 kW (365hp), which was achieved by a slightly raised compression, a different camshaft and an increase in turbocharger pressure. In order to operate the car with these changes in racing over 24 hours without engine overheating, Porsche built a larger charge-air cooler and oil in the vehicle. In addition, the vehicles had a special tires with front 9.5 J x 16 and Rear 11J × 16 wide rims. For the engine and chassis changes the teams had around 28,000 DM additionally invest to the car price.
