Porsche 911 (993) - Adrian Streather
1 Is it the right car for you?
– marriage guidance
Tall and short drivers
Taller drivers will find the left-hand drive 993 more comfortable than right-hand drive models.
Weight of controls
All factory-built 993s, except the Carrera RS, are fitted with power-assisted rack and pinion steering, which helps reduce loads on arms significantly. There are two brake boost systems used in the 993: vacuum for the Carrera models, and hydraulic for the rest. The hydraulic brake boost system is very light when it’s working properly, but the brake pedal will go very hard if hydraulic pressure drops. The normally-aspirated 993’s hydraulic clutch operating system is heavy, and driving in dense traffic will result in a very sore left leg. The turbocharged 993s are fitted with a clutch power boost system to assist the driver, but it’s still heavy.
Will it fit the garage?
Measure it and see, but don’t forget that the doors have to be opened in the garage. Model specific dimensions are found in chapter 17.

Interior space
There’s plenty of legroom in the front for driver and passenger, though comfort depends on the type of seats installed. The standard comfort seat nicely supports people of average girth. The sport, bucket, and racing seats are designed for those who are not so wide at the hips, and the rear seats are essentially useless.
Luggage capacity
The 993 is a thoroughbred sports car, and is susceptible to poor handling caused by uneven weight distribution over the wheels. There is sufficient room in the back with both rear seat backs down to carry a lot of luggage; but keep it light. The front luggage compartment has sufficient room for a soft bag for heavy items.
Running costs
Porsche 993 servicing costs are higher than normal because it’s a Porsche. Running costs are higher than normal because air-cooled engines burn oil as well as petrol, and the fuel economy isn’t brilliant either.
Usability
It’s a high performance sports car and, even with winter tyres, neither the rear-wheel drive nor the viscous coupling all-wheel drive models are effective in snow and ice conditions. No 993 model is particularly good in winter, and salt on the roads will destroy the metalwork.
Parts availability
Almost all original 993 parts are still available.
Parts cost
Original Porsche parts for the 993 are not cheap, and increase in price every year.
Insurance
Check with your insurance company, as a 993 can be very expensive to fully insure. If you cannot afford full insurance coverage you shouldn’t purchase it.
Investment potential
The whole 993 model range is holding its resale value well, and much better than all other 911 series, but you’re always going to put more money into it than you make if it does appreciate in value.
Foibles
Creaking, grinding and groaning noises – can be annoying in the Cabriolet and Targa styles, though the Coupé does not escape.
Engine electrical harness reliability for the model year 1994, 1995 Carrera and Carrera 4, and in model year 1996 for the 993 Turbo.
Problems with various parts of the Cabriolet roof system, including a recall.
Complicated engine control and exhaust emissions system installed into the US market versions and, regardless of the market, all twin turbocharged models.
Plus points
Every girl loves a Porsche. The 993 is meant to be driven and loved (witness the driver’s huge smile).
Beautiful sexy body curves never to be seen again.
It’s the King of Porsche.
Minus points
Cost of ownership.
Specialist test equipment required.
Insufficient professional technical knowledge, repair and fault finding skills.
