So, what is so great about the Porsche 911 3.2 Carrera?


[pullquote align=”normal” cite=”My old Porsche website on CIX in the days of html websites and page counters”]So I found this old Porsche website I did around 2000. Hard to believe its sixteen years ago… Lots of waffle about Porsche 911 3.2 Carrera and decided to repost it just in case its of interest?[/pullquote]


Engine Enhancements Engine Management Enhancements
The engine size was increased to 3,164 cc by using the longer stroke 74.4 mm crankshaft from the 3.3 turbo and the 95 mm bore pistons the 911 SC had used.The compression ratio was raised from 9.8:1 to 10.3:1 giving a maximum power 231 DIN horsepower at 5900 rpm.

The torque was 209 lb/ft at 4200 rpm.

The chain tensioner problem that had plagued earlier models of the 911 was finally solved by going to a pressure fed design.


The Motronic engine management system created a more efficient engine.Linked to sensors monitoring air flow, engine temperature and atmospheric pressure. It adjust engine timing and fuel usage dependent on the most efficient setting programmed into it.

This causes better fuel consumption, smoother idle, broader power-band, controlled carburetion, a rev limit set to 6520 rpm, less exhaust pollution…

Body Enhancements Interior Enhancements
The brakes were improved on the Carrera to cope with its increased performance potential. All round rotor thickness was increased to 24 mm (from 20.5 mm) to improve the cooling of the brakes. The rear calliper diameter increased from 38 mm to 42 mm for additional friction, and therefore, improved braking. A pressure regulator was added to the rear brake circuit to prevent the rear wheels from locking. Pad wear indicators were also added to monitor brake pad wear.Porsche also offered the turbo look body, which they called the 911 Carrera with 930 Performance Body/Chassis option. 930 is the Porsche designation for the 911 Turbo. So this new type of Carrera had turbo body work, suspension, brakes and larger turbo wheels and tires. The front wheels and tires were 7 x 16 with 205/55 VR 16 while the rear were 8 x 16 with 226/50 VR 16 The in-car heater was improved by adding two extra blowers in the heating ducts of the passenger compartments. The extra blowers have three speeds and greatly improved the air circulation. All of the air outlet vents in the instrument panel are an all new larger design greatly improving the operation of the air conditioner.

There reason for shortening the shift travel was to avoid having the shift lever scrape the seat going into second gear when the car had sport seats. They shortened the shift travel by about 10% by moving the pivot point up by 4 mm. Starting with the 1985 model Porsche also using Boge GZ double-tube gas pressure shock absorbers as an option to the Bilstein single tube gas pressure shock absorbers as an option on the Turbo Look cars. The oil cooler was changed to a finned radiator type cooler. To provide extra airflow the opening in the front bumper was increased in size. This change was to provide a reduction of about 20~ C while driving at full load. Some Porsche customers had experienced engine failures when driving at full speed on the autobahns. Electrically operated central door locks were also added in 1984. The telescopic fender mounted antenna was replace with an active radio antenna which was mounted in the windshield.

The 1986 911 Carreras now had Boge double tube low pressure gas shock absorbers as standard equipment. The front sway bar diameter was increased from 20.0 mm to 22.0 mm. The rear torsion bars were increased in diameter from 24.1 mm to 25.0 mm. The rear sway bar was also increased in size from 18.0 mm to 21.0 mm. The 911 Turbo Look models had different size tires and rims on the rear wheels. The rim size was changed from 8J x 16 with a 10.3 mm offset with 225/50 VR 16 tires to 9J x 16 with a 15 mm rim offset with 245/45 VR 16 tires. The Cabriolet now had an optional electrically operated

Cabriolet top. 1986 was the first year that the Turbo fenders, with their fender flares, were made one piece for the front and rear instead of welded on flares as they had been previously.So, what is so great about the Porsche 911 3.2 Carrera? 2

The 1987 Carrera had a completely new five speed transmission, Type Code G 50, which utilized Borge Warner synchronizers for smoother shifting and improved durability. The clutch was increased from 225 mm in diameter to 240 mm to cope with the increased power of the larger 3.2 litre engine. The new larger clutch was also now activated by a hydraulic master and slave cylinder. The rear torsion bar tube has a bent centre section to provide additional clearance for the transmission. The additional clearance is required for the new clutch disc with larger rubber damper centre section. The 1987 911 Carrera and 911 Turbo had new headlights that are optically standard for R.o.W. and USA. 911 Carreras equipped with a catalytic converters had an additional electric blower mounted on the oil cooler in the right front wheel housing to prevent excessive oil temperatures. The fan is controlled by a temperature switch which is mounted in the top of the oil cooler. This switch turns on the fan when the oil temperature reaches 118~ C (244~ F). The power curves for the US version of the engine were upgraded to 217 DIN horsepower at 5900 rpm. and peak torque to 195 lb/ft at 4800 rpm.

Porsche also decided to put better brake system on the Carrera 3.2 : it received 282x24mm front and 290x24mm discs rear (instead of 282×20.5mm and 290x20mm). Pistons of the rear brake callipers increased to 42mm (as front ones) and to prevent wheel locking under big braking (which is very frequent with same pistons’ size front and rear), a pressure regulator get added to the rear brake circuit. Finally, the servo brake diameter reached 8 inches, as on the 911 turbo.
For the first year of the model, the chassis hasn’t been improved. The wheels and tyres size were similar to those of the 911 SC (185/70 VR 15 on 6J15 front and 215/60 VR 15 on 8J15 rear). Modifications will come in 1986 when Porsche equipped the Carrera 3.2 with Bodge twin tube gas shock absorbers. The front sway bar diameter raised from 20mm to 22mm and the rear ones from 18mm to 21mm. As an end, rear torsion bars now have a 25mm diameter instead of 24.1mm.

So, what is so great about the Porsche 911 3.2 Carrera? 3Possibly one of the most noticeable *driving* aspects of the 3.2 Carrera is because Porsche decided to produce a new transmission : the type G50 gearbox. This gearbox use modern Borg-Warner synchronizers for better shifting. The diameter of the clutch is enlarged from 225 mm to 240 mm and the command now use hydraulic mechanism more than previous cable one. As a result, the effort produced to operate clutch are less important and the shifting operation is more comfortable to execute.

The look of the Carrera 3.2 is very similar to the previous 911 SC and few details can make the difference : rear logo on the engine lid, integrated fog lights in the front spoiler, new ‘dial’ wheels and since 1987, the integration of rear fog lights into the rear headlights strip lead to the modification of the Porsche logo. Previously black and big, it gets to the colour of the red rear strip. But compared to the 911 SC, the car was more powerful and the behavior was improved. Moreover, the Carrera 3.2 is a more luxurious car with a new ventilation system, new seats and interior modifications.
