The Porsche 930, more commonly known as the 911 Turbo, is a high-water mark in Porsche history. Introduced in 1975 and sold through 1989, it was Porsche’s first production turbocharged 911 and, for many enthusiasts, the most visceral. With its distinctive wide fenders, whale tail spoiler, and raw turbo lag that hits like a hammer, the 930 defined an era of excess and excitement. But while it’s an icon, buying a 930 today requires a careful, informed approach. This guide covers what to look for, what to avoid, and what you can expect when owning one of the most legendary air-cooled Porsches.
A Brief History
The 930 debuted in 1975 with a 3.0-liter flat-six engine producing 256 horsepower. This was serious output for the time—especially paired with the lightweight 911 chassis. In 1978, Porsche upgraded the 930 with a 3.3-liter engine and an intercooler, boosting power to 300 hp (282 hp in U.S. spec due to emissions). The model remained relatively unchanged through the 1980s until it was replaced by the 964 Turbo in 1990.
One quirk of early 930s is the four-speed transmission. Porsche engineers believed the torque of the turbocharged engine made a five-speed unnecessary. This gives the 930 a unique feel—tall gearing and a dramatic turbo rush starting around 3,500 RPM. Driving a 930 is more art than science; it rewards finesse but punishes mistakes.
What to Look For
1. Model Year Differences
-
1975–1977 (3.0L): Lightweight and raw, but also the most temperamental. Known for brutal turbo lag and less forgiving handling. These early cars are also the rarest and most valuable.
-
1978–1989 (3.3L): More power, better brakes, and improved reliability. Most buyers prefer the 3.3L for its usability and refinement. U.S. models have slightly less power than their European counterparts.
2. Maintenance and Documentation
A well-documented service history is essential. Look for records of:
-
Regular valve adjustments (every 12,000 miles)
-
Turbocharger rebuilds (they can wear out)
-
Timing chain tensioner upgrades
-
Clutch replacements (especially if it’s still running the original)
-
Intercooler and fuel system maintenance
Cars that have been sitting idle for years are risky. A PPI (pre-purchase inspection) from an air-cooled Porsche specialist is non-negotiable.
3. Rust and Body Condition
Despite Porsche’s build quality, rust can be an issue—especially in early models. Key rust-prone areas include:
-
Door bottoms and sills
-
Front suspension pan
-
Battery box
-
Rear arches
Some 930s have lived hard lives, and poor crash repairs or fiberglass fender flares are red flags. Always check that the car still has its original VIN tags and matching numbers engine and gearbox if collectability matters to you.
4. Modifications
Many 930s were modified during the tuner craze of the ’80s and ’90s. Popular mods include:
-
Aftermarket wheels and suspension
-
Boost controllers for more aggressive turbo response
-
Slantnose conversions (some factory, many not)
-
Stereo and interior updates
While tasteful upgrades aren’t necessarily a deal-breaker, originality matters for long-term value. Factory paint, matching engine numbers, and Porsche COAs (Certificates of Authenticity) go a long way when it comes time to sell.
Ownership Experience
Owning a 930 is not like owning a modern 911. It’s a thrilling, analog experience that demands respect. The turbo lag is dramatic, the brakes require a firm foot, and the car’s tendency to oversteer at the limit can catch the uninitiated off guard. That said, it’s a remarkably engaging car to drive when you get the hang of it.
Mechanical reliability is strong if the car has been properly maintained. Expect to budget around $2,000 to $5,000 annually for upkeep, more if you plan on regular track use or if major work is needed. Parts availability is generally good, though some trim pieces and early turbo-specific parts can be hard to find or expensive.
The interior is a no-nonsense 911 layout—minimalist but driver-focused. The seats are supportive, the gauges are legible, and the visibility is excellent. Don’t expect modern infotainment or climate control, but that’s part of the charm.
Values and Market Trends
As of mid-2025, Porsche 930 values have remained strong:
-
Early 3.0L cars (1975–1977): $180,000–$350,000 depending on condition and originality
-
3.3L cars (1978–1985): $120,000–$200,000
-
Later models (1986–1989): $140,000–$220,000
Special models like the factory slantnose (Flachbau) or low-mileage, one-owner examples can command well over $250,000.
The 930 market cooled slightly from its 2016–2018 peak but has stabilized and even rebounded, especially for top-tier examples. As the last of the truly analog turbo Porsches, the 930 continues to attract collectors and drivers alike.
Final Thoughts
The Porsche 930 is not a car you buy on impulse. It’s a serious machine with real performance and real maintenance demands. But for those who value raw, undiluted driving experiences and iconic ‘70s and ‘80s styling, the 930 is near the top of the list.
If you want a Porsche that’s more than just a badge and numbers—it’s a challenge, a thrill, and a legend—the 930 might just be your perfect analog dream. Just make sure you’re buying with your eyes wide open—and your right foot ready to modulate the boost.
