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
Porsche 911 Turbo S2 (964) (1992)
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.
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.
All Porsche 911s are turbocharged these days but the Turbo model is something special. It gets the twin-turbo 3.7-liter flat six with tons of power and a huge $33,000 savings over the Turbo S. Thanks to an output of 573 hp, marking an increase of 32 hp over the predecessor, the new 911 Turbo Cabriolet accelerates from 0 to 60 mph in 2.8 seconds (0.2 seconds faster than before). The Turbo Cabriolet basically handles like a coupe.
It would be a disservice to call this new Turbo a "lesser" car than the Turbo S, but it does have less in most departments. Less power at 573 HP. Less features compared to the jam-packed Turbo S. Most importantly, less money required to put one in your garage. This also is not to say that the new Turbo isn't anything short of a monster. It will still go 0 to 60 in 2.8 seconds, will corner like it was on rails with Porsche Torque Management (PTM) all-wheel-drive.
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.
The Cabriolet version of the 991.2 Turbo got the same updates as its coupe sibling. The engine in the 991.2 911 Turbo Cabriolet is a twin-turbocharged flat-six with 540 horsepower and 523 pound-feet of torque, up a decent 20 more horses versus the 991.1 Turbo Cab. Improvements that come from increases in boost and fuel-injection pressures. Rounding the skidpad, the Turbo posts 1.02 g’s relatively easily. The wide P Zeros in back and the standard four-wheel steering conspire to hide the fact that 62 percent of the Turbo’s 3656 pounds sits over the rear wheels. 0 - 60 mph is over in just 3 seconds.
At the heart of the 991.2 911 Turbo is a twin-turbocharged flat-six with 540 horsepower and 523 pound-feet of torque. That’s a meaningful 20 more horses than the 991.1 Turbo. Improvements that come from increases in boost and fuel-injection pressures. Rounding the skidpad, the Turbo posts 1.02 g’s relatively easily. The wide P Zeros in back and the standard four-wheel steering conspire to hide the fact that 62 percent of the Turbo’s 3656 pounds sits over the rear wheels. With sport-plus selected, the 991.2 Turbo hits a 1.0-second run to 30 mph and a 2.6-second zero-to-60 time.
