Best Air-Cooled Porsche 911 Turbo<\/h1>\n

The 930 vs 964 vs 993. A Special Guide.<\/h2>\n

A showdown of the iconic 911 Turbo nameplate<\/h2>\n
The Widowmaker<\/em><\/h5>\n

The Variants<\/strong><\/h4>\n

Porsche 911 Turbo 3.0 (930) (1975 \u2013 1977)<\/strong><\/h3>\n

The 911 Turbo was put into production in 1975. While the original purpose of the 911 Turbo was to gain homologation for the 1976 racing season, it quickly became popular among car enthusiasts. Ernst Fuhrmann adapted the turbo-technology originally developed for the 917\/30 CAN-AM car and applied it to the 3.0 litre flat-six used in the Carrera RS 3.0, thus creating what Porsche internally dubbed as the 930. Total power output from the engine was 260 bhp and 254 ft lbs of torque.<\/span><\/p>\n

Porsche 911 Turbo 3.3 (930) (1978 \u2013 1989)<\/strong><\/h3>\n

Porsche made its first and most significant changes to the 930 for 1978 model year, enlarging the engine bore by 2 mm (0.08 in) to a total displacement of 3,299 cc (3.3 L; 201.3 cu in) and adding an air-to-air intercooler. The suspension benefitted from new anti-roll bars, firmer shocks and larger diameter rear torsion bars. While the increase in displacement increased power output and torque, it also increased the weight of the vehicle, which contributed to a substantial change in the handling and character of the car compared to the Earlier 3.0-Litre Models.<\/span><\/p>\n

The Variants<\/strong><\/h4>\n

Porsche 911 Turbo 3.3 (964) (1991 \u2013 1992)<\/strong><\/h3>\n

The 1989\/90 change of model year saw the launch of the Porsche 911, 964 series onto the market. This 911 model was initially available as a Coupe, Targa and Convertible. From model year 1991 onwards Porsche also introduced its top-of-the-line model – the Turbo – into this series. In spite of bearing a major similarity in terms of look to the naturally-aspirated model, the extended wings remained. This meant that the new Porsche could retain its turbo look. The 964 Turbo model was the successor to the Porsche 930. The 964 Turbo was the end of an era, the last of the single turbo rear-wheel drive 911 Turbos.<\/span><\/p>\n

Porsche 911 Turbo S 3.3 (964) (1992 \u2013 1993)<\/strong><\/h3>\n

Porsche made a lightweight version of the Turbo simply known as the Tuubo S. This used the spartan appointments of the Carrera RS with an upgraded version of the Turbo engine. Some cars received graphics on the side celebrating IMSA Supercar Championship. Similar to the Carrera RS, the Turbo S had no power steering, air conditioning, airbags, central locking, alarm system, rear window wiper, smaller window washer reservoir, smaller horn, and had thin-gauge glass. The engine used a second oil cooler and slightly higher boost to improve overall performance.<\/span><\/p>\n

Porsche 911 Turbo 3.6 (964) (1993 \u2013 1994)<\/strong><\/h3>\n

Engine based on modified 3.6 litre 964 unit. Speedline wheels with big red brake calipers. Lessons learned in the Carrera Cup series proved the reliability of the new 3.6-litre engine. An additional three millimetres on the bore and two millimetres on the stroke, resulted in an increase in capacity of 300 cc. Combined with the turbo optimised cylinders, pistons and crank train, and an increase in the compression ratio from 7.0 to 7.5:1, this helped to boost power to 360 bhp. Torque was increased significantly to 520 Nm at 4200 rpm, up from 450 Nm at 4500 rpm in the earlier car.<\/span><\/p>\n

Porsche 911 Turbo 3.6 S (964) (1994)<\/strong><\/h3>\n

19 non ‘slant nose’ or Package cars were made for the USA only. Very rare. The Porsche factory had 93 Turbo chassis left. These were all transferred to Porsche Exclusiv and hand built as the very special 964 Turbo 3.6 S. They were offered with normal, or \u2018Flachbau\u2019 slant nose front ends. While the vast majority of Turbo S\u2019 were fitted with the \u2018Flachbau\u2019 nose as a no-cost option, the Turbo S could also be had with the traditional 964 nose as well. In all, 76 Flatnose cars were made while 17 non-Flatnose (known as Package option) cars were made. These cars were also fitted with the X88 option, which increased power to 380 hp.<\/span><\/p>\n

The Porsche factory had 93 Turbo chassis left. These were all transferred to Porsche Exclusiv and hand built as the very special 964 Turbo 3.6 S.

In all, 76 Flatnose cars were made while 17 non-Flatnose (known as Package option) cars were made. These cars were also fitted with the X88 option, which increased power to 380 hp. 75 flatnose units were produced.<\/span><\/p>\n

Porsche 911 Turbo S2 (964) (1992)<\/strong><\/h3>\n

A forgotten part of the 964s history is the Turbo S2. It was built to adhere to homologation rules so Porsche could participate in IMSA’s sports car racing series. IMSA’s homologation rules meant that Porsche had to build at least 200 road-going versions of the participating car, 20 of which needed to share most of the primary components of the race car. The 911 Turbo S2 was built specifically for this purpose and exclusively for the United States and Canada. The 20 homologation specials left the factory as stock 964 Turbos, heading immediately to California-based tuner for “S2” engine upgrades.<\/span><\/p>\n

Porsche 911 Turbo Cabriolet (964) (1993)<\/strong><\/h3>\n

The Turbo-look Porsche 964 has always been a very desirable automobile, among them 1,532 Carrera 2 Cabriolets constructed worldwide. Within that group, there were some cars that were even more specialized. The Register says six Turbo-look cabriolets were pulled off the production line in Zuffenhausen and transported to the Porsche Exclusive shop in Weissach. Three of these six powerful and luxuriously equipped drop-tops were equipped with left-hand drive for buyers in Germany (Code C00), and the other three were fitted with right-hand drive.<\/span><\/p>\n

The end of an era<\/em><\/h5>\n

The Variants<\/strong><\/h4>\n

Porsche 911 Turbo (993) (1995 \u2013 1998)<\/strong><\/h3>\n

The 993 Turbo was available between late 1995 to 1998. Powered by a twin-turbocharged 3.6 liter flat six, it was rated at 402-horsepower. It\u2019s distinguished easily from the rear, as the whale-tail spoiler is quite deep to house the intercoolers meant to cool the intake charge. This extra power might have been a handful for street drivers, so all-wheel drive from the 993 Carrera 4 added traction at all four corners. Approximately 6,000 coupes were made. Although powered by a different engine, a limited production 993 Turbo Cabriolet was available in the early days of the 993 generation. A more powerful 993 Turbo S was also introduced in 1997.<\/p>\n

Porsche 911 Turbo S (993) (1997 \u2013 1998)<\/strong><\/h3>\n

The 993 Turbo S, available between 1997 and 1998, bumped the power from the standard 993 Turbo up to 450hp (430 for the United States market) with larger turbochargers and a modified engine management system. The Turbo S was fitted with more luxury trim bits on the interior \u2013 with more leather and carbon fiber than on the standard Turbo. A larger rear wing was installed as well. Only 345 were built. Its direct successor was the 996 Turbo S for model year 2005.<\/p>\n","protected":false},"excerpt":{"rendered":"
