The last rear-drive 911 Turbo — single-turbo, air-cooled and manual only.
The 964 Turbo (1990–1994) is the last rear-wheel-drive 911 Turbo. It replaced the long-lived 930 in Porsche's air-cooled turbo line and carried it into the modern era, but retained the 930-derived engine architecture at launch and Porsche's G50 five-speed manual gearbox throughout production. Every 964 Turbo drove the rear wheels alone; the following 993 Turbo moved permanently to all-wheel drive.
The range ran in two clearly distinct phases: the 320 PS Turbo 3.3 (1990–92), essentially a modernised evolution of the 930's engine in the 964 chassis, and the low-volume Turbo 3.6 (1993–94), which fitted a new M64-based 3.6-litre turbocharged flat-six producing 360 PS. The 3.6 is the collector grail of the range.
The last rear-drive, air-cooled, single-turbo, manual 911 Turbo — a specification Porsche has never revisited and will not repeat. The 964 Turbo 3.6 is the terminal expression of that recipe and one of the most sought-after air-cooled 911s.
| Variant | Years | Production | Notes |
|---|---|---|---|
| Turbo 3.3 (1990–1992) | 1990–1992 | ~3,660 | 3.3L (930-derived) single-turbo air-cooled flat-six, 320 PS / 320 bhp, G50/50 5-speed manual, rear-wheel drive. X88 factory Powerkit raised output to 355 PS on a small subset of cars. |
| Turbo 3.6 (1993–1994) | 1993–1994 | ~1,437 | 3.6L M64 single-turbo air-cooled flat-six, 360 PS / 355 bhp, 384 lb-ft, G50/50 5-speed manual, rear-wheel drive. Distinguished visually by the 'Speedline' polished five-spoke wheels and the tea-tray rear wing. The 'Bad Boys' car and the collector benchmark for the generation. |
| Turbo 3.6 S (Exclusiv / Flachbau) | 1993–1994 | Not separately recorded | Rare Sonderwunsch subset (~90 leftover chassis) of the 3.6, uprated to ~380 hp and available with the Flachbau slant-nose. Counted separately from the standard Turbo 3.6 production run. |
Start with identity, paperwork and originality. The strongest cars have a continuous Porsche or recognised-specialist service file, original paint, matching numbers, both keys, complete books and tools and — where available — the Porsche Certificate of Authenticity and factory build documentation. For the 964 Turbo, focus on original-paint 3.6 cars with continuous Porsche or air-cooled-specialist history; a documented Turbo 3.6 is the strongest configuration.
The 964 Turbo's flat-six is fundamentally robust but is a specialist unit when tired; head-stud pull-through, oil-return integrity and turbocharger health are the practical variables. This is not a car to buy without an air-cooled Porsche specialist involved. A proper pre-purchase inspection includes cold-start behaviour, an undertray-off inspection of the flat-six and gearbox, chassis and suspension survey, brake condition and a long enough road test to expose heat- and load-related faults. Deferred maintenance on a specialist Porsche is almost always more expensive than buying a better-sorted example.
Use a paint-depth gauge, a lift inspection and a specialist familiar with the model's factory panel gaps. Confirm any PPF history; inspect splitters, diffusers and undertrays for evidence of contact; and price concealed accident or heat damage severely.
Specification, colour and factory options move values meaningfully. Buy the best-documented example in the most desirable specification you can justify rather than a tired car of a rarer derivative that will need years of corrective work.

The last rear-drive, air-cooled, manual 911 Turbo — a fixed, non-repeatable specification. The 3.6 in particular is a defined collector benchmark with permanent narrative and low absolute supply.
