Porsche 930 Turbo Buying Guide: The Original Widowmaker

How to Choose

• The 3.3-liter (1978-1989) is the better buy for most people. More power, an intercooler, and better refinement than the 3.0.
• The 1989 G50 gearbox car is the holy grail for drivers — the earlier 4-speed 930 gearbox is notchy and agricultural.
• Turbo lag is the defining character trait. The boost comes on suddenly around 3,500 rpm. Learn to manage it or it will manage you.
• Slantnose (Flachbau) cars are dramatically rarer and command 50-100% premiums. Factory slantnose vs aftermarket conversion matters enormously for value.
• Rust is the biggest structural concern. Check the kidney areas, front trunk floor, and battery box thoroughly.

Frequently Asked Questions

How much is a Porsche 930 Turbo worth?

Standard 930 Turbos range from $80K for driver-quality examples to $200K+ for concours-condition late models. The 1989 G50 cars and factory slantnose variants command the highest premiums, often exceeding $250K.

Is the 930 Turbo dangerous to drive?

The 930's reputation comes from its sudden turbo boost delivery combined with rear-engine weight distribution. It demands respect and smooth inputs, especially in the wet. Modern tires have made it significantly more manageable than in period. It's not dangerous — it's demanding.

What's the difference between a 930 3.0 and 3.3?

The 3.3 (1978+) added an intercooler, larger turbo, and 40 more horsepower (300 vs 260hp). It also got improved brakes from the 917 race car. The 3.0 is rarer (only 3 model years) and more collectible, but the 3.3 is the better-driving car.

Should I buy a 930 Turbo or a 964 Turbo?

The 964 Turbo (1991-1994) is significantly easier to live with — better brakes, better gearbox, modern conveniences. The 930 is the rawer, more visceral experience and the more iconic design. Buy the 930 for character, the 964 for capability.
