Porsche 964 911 1989–1994
beats me, but here we go...
[B]Porsche 964[/B]
The Porsche 964 is the company's internal name for the Porsche 911 manufactured and sold between 1989 and 1994. Designed by Benjamin Dimson through January 1986, it featured significant styling revisions over previous 911 models, most prominently the more integrated bumpers. It was the first generation 911 to be offered with Porsche's optional Tiptronic automatic transmission and all wheel drive as options.
[B]Name[/B]
Type 964 ("nine-sixty-four", or "nine-six-four") is Porsche's internal code name for the 911 Carrera 2 and 911 Carrera 4 models, which were badged simply as "Carrera 2" and "Carrera 4". "964" is used by automotive publications and enthusiasts to distinguish them from other generations of the Carrera.
[B]Carrera 2 and 4[/B]
The 964 was considered to be 85% new as compared to its predecessor, the Carrera 3.2. The first 964s available in 1989 were all wheel drive equipped "Carrera 4" models; Porsche added the rear wheel drive Carrera 2 variant to the range in 1990. Both variants were available as a coupe, Targa or Cabriolet. The 964 Carrera was the last generation sold with the traditional removable Targa roof until the 2011 991 (993, 996, and 997 versions used instead a complex glass-roof "greenhouse" system). A new naturally aspirated engine called the M64 was used for 964 models, with a flat-6 displacement of 3.6 litres. Porsche substantially revised the suspension, replacing torsion bars with coil springs and shock absorbers.[2] Power steering and ABS brakes were added to the 911 for the first time; both were standard. The exterior bumpers and fog lamps became flush with the car for better aerodynamics. A new electric rear spoiler raised at speeds above 50 mph (80 km/h) and lowered down flush with the rear engine lid at lower speeds. A revised interior featured standard dual airbags beginning in 1990 for all North American production cars. A new automatic climate control system provided improved heating and cooling. Revised instrumentation housed a large set of warning lights that were tied into the car's central warning system, alerting the driver to a possible problem or malfunction.
[B]Turbo[/B]
Porsche introduced the 964 Turbo model in March, 1990[3] as the successor to the 930. Unfortunately, they hadn't had the necessary time to develop a turbocharged version of the 3.6 litre M64 engine, and chose to re-use the 3.3 litre engine from the 930, with several minor revisions that made the engine smoother, less prone to turbo lag and more powerful, with a total output of 319.95 PS (235.32 kW; 315.57 hp) @ 5750 rpm. A total of 3,660 of the 964 Turbos were built.
In 1992, the 3.3 litre Turbo S was introduced. The standard turbo model was modified to produce 381.36 PS (280.49 kW; 376.14 hp) with bigger injectors and more boost and more aggressive camshafts and with a lightweight interior and limited "creature comforts" the Turbo S was one of the fastest cars on the road. With lowered suspension, a front strut brace and manual steering, the Turbo S was geared to performance. 86 cars were produced.
Porsche released the 964 Turbo 3.6 in January, 1993,[3] now featuring a turbocharged version of the 3.6 litre M64 engine and producing 359.95 PS (264.74 kW; 355.03 hp) @ 5500 rpm, the 3.6 litre powered Turbo was produced only for model year 1993/1994, with fewer than 1,500 of them produced in total, making it one of the rarest and most sought after Porsches produced since the 959.
At the end of 964 production in 1994, the Porsche factory had some 90 Turbo chassis left. These were all transferred to Porsche Exclusiv and built as the very special Turbo 3.6S. The Turbo 3.6S was available either with the traditional 964 Turbo 3.6 body, or with the exclusive flachbau 'slant nose' option.
Option X83 (Japan), X84 (ROW) and X85 (USA), the Turbo S Flachbau, was available in the US as a $60,179 USD option on top of the base price $99,000 USD Turbo 3.6. The flachbau option was available when ordering the no charge '36S' option '1994 Turbo "S" Model' at a price of $60,179. In addition to the slantnose fenders, it also included the 'X88' option which included the 'Turbo S' motor, the 'X92' Exclusive front spoiler, 'X93' Exclusive rear spoiler and 'X99' Exclusive rear fender vents. The flachbau option was designed around the model 968 front end for the ROW and USA versions and the 930 style Turbo S front end for Japan (right down to the sill covers on the fenders). 39 Models were made for US markets, 27 for the Rest of the world, and 10 for Japan all in Polar Silver
[B]964 Speedster[/B]
There were two distinct incarnations of the air-cooled 911 Speedster. The first was the 1989 model year Speedster. Shown at the 1988 Frankfurt autoshow beside the upcoming Carrera 4, the 1989 Speedster actually shared more in common with the 930 turbo than with the upcoming 964 generation 911s, causing it to be looked upon, in retrospect, as a much inferior "driver's car" to the later 1994 Speedster. More than three quarters (641) of the 800 built had the "Turbo look" wide-body option.
The 1994 Porsche 911 Speedster was available either in standard or lightweight trim called “clubsport." Unlike the 1989 model, the 1994 Speedster was based on the new Carrera 2 platform and was not initially available with the "Turbo look" wide-body style. The 1994 Speedster was designed to be a more focused "driver's car" and served as a hybrid between a 964 Carrera 2 Cabriolet and a 964 RS. While it featured a softer suspension set up than the 964 RS, it offered almost none of the comforts of a normal 964 Carrera 2 Cabriolet, though power windows were standard and it was available with air conditioning and a stereo. Porsche planned to build 3000 examples of the 1994 Speedsters in 1992, but only 936 examples were built and sold during the two years of production. Once again, the United States was the most important market with 427 Speedsters heading Stateside. Right hand drive versions were exceptionally rare this time, with only 14 cars having the steering wheel on the ‘proper’ side compared to 139 examples in right hand drive of the pre-964 911 Speedster. In addition, 20 special examples were finished at Porsche Exclusive's workshop at Werk 1 (Factory 1) with the optional “Turbo look” wide-bodies.
A turbo-bodied cabriolet version was released in 1992. This had the standard electric spoiler and turbo guards. Mechanically, it was the same as the standard model, apart from 17" cup wheels and the brakes and suspension, which were 'Turbo' specification. Only 250 of this variant were produced, in total, during the 1992 and 1993 model years.
