Overview
The 993, built from 1993 to 1998, is the final air-cooled Porsche 911 generation. Porsche introduced a new multi-link rear suspension and a six-speed manual while retaining the compact flat-six character that attracts collectors. The range extends well beyond a standard Carrera: driven wheels, roof type, wide-body specification and motorsport models all change what the car is. A buyer should establish the exact factory variant before comparing asking prices, then give corrosion, oil leaks and service evidence as much attention as the paintwork. Porsche model history
Versions and engines
Read this section: Versions and engines
- Carrera and Carrera 4: 3.6-litre air-cooled flat-six, initially 272 PS and 285 PS from model year 1996. Porsche offered a six-speed manual or optional Tiptronic automatic. Porsche model history
- Targa, Carrera 4S and Carrera S: The Targa uses a retracting glass roof. The Carrera 4S and rear-wheel-drive Carrera S pair wide Turbo-style bodywork with a naturally aspirated engine. Porsche model history
- Turbo: Twin-turbocharged 3.6-litre flat-six with 408 PS in standard early form; factory power upgrades and the later Turbo S require specification checks. Porsche model history
- Carrera RS and GT2: Specialist, motorsport-oriented variants with substantially different equipment from a Carrera. Verify factory identity before valuing a car as either model. Porsche model history
What drives the price
Read this section: What drives the price
Factory variant comes first. A narrow-body Carrera, glass-roof Targa, wide-body S model and Turbo serve different buyers; a wide-body conversion does not make a Carrera a factory Carrera S. Manual versus Tiptronic, driven wheels, colour and original equipment then refine the comparison. Porsche introduced the VarioRam intake for the 3.6-litre engine in 1996, so confirm engine specification as well as the build date when comparing cars. Porsche model history
On any variant, a credible specialist file supports an asking price better than a low odometer reading with deferred work. Look for oil-leak repairs, suspension renewal, gearbox servicing and evidence that heating and air conditioning work correctly. Corrosion repairs should include photographs and invoices. A collector car still needs a thorough underside inspection. Revolution Porsche buying guide
Common problems and what to inspect
Read this section: Common problems and what to inspect
- Oil leaks: Seals and chain or valve covers can leak onto hot exhaust parts. Look below the engine, then check for a burnt-oil smell or smoke from the rear wheel-arch area after driving. Revolution Porsche buying guide
- Corrosion: Inspect the underside, exhaust heat shields and silencer welds on a lift. Check around previously replaced glass and ask for photographs of any repairs. Revolution Porsche buying guide
- Suspension: Worn components and poor alignment can spoil the car’s steering. Ask what has been replaced, with which parts, and whether the geometry was set afterwards. Revolution Porsche buying guide
- Heating and air conditioning: Try warm and cold air at every vent. Do not assume a weak system only needs a refrigerant refill. Revolution Porsche buying guide
- Alarm and electrical system: Check for unexplained alarms, dampness around the cabin and evidence of non-standard wiring. Revolution Porsche buying guide
Running costs

The air-cooled engine still needs regular oil services, and an older car may need seals and oil lines attended to between scheduled visits. Check the manual gearbox oil history, clutch operation, brake discs from both sides and suspension records. Porsche fitted hydraulic valve-clearance compensation to the Carrera engine, so do not assume the older air-cooled 911 valve-adjustment routine applies unchanged. A Turbo or motorsport variant needs a maintenance assessment specific to its engine and equipment. Porsche model history · Revolution Porsche buying guide
FAQ
Read this section: FAQ
Why is the 993 sought after? It is the final air-cooled 911 generation and combines that engine layout with a revised rear suspension. Those facts explain interest, but they do not remove the need for a mechanical inspection. Porsche model history
Is a Carrera 4S a Turbo? No. It has the wide-body look and all-wheel drive, but a naturally aspirated Carrera engine. Porsche model history
Does every 993 have VarioRam? No. Porsche introduced it on the 3.6-litre engines in 1996; verify the individual car’s engine specification. Porsche model history
What should a pre-purchase inspection prioritise? Ask for an underside examination, oil-leak assessment and suspension check. Test the cabin heating and air conditioning as well. Revolution Porsche buying guide
