Structural Rust
Battery trays, floor pans, kidney bowls, and rear suspension mounting points are all rust-prone. Repairs are expensive and can affect structural integrity. A rust-free car is worth a significant premium.
Turbo Lag / Oversteer Characteristics
The 930's massive turbo lag and snap oversteer make it a handful to drive quickly. Smooth throttle application and respect for the turbo spool are essential. Modern tires help significantly.

Porsche 911 (930) Buyer's Guide
The Turbo Icon
The 930 Turbo (1975-1989) is the car that defined Porsche for a generation. With its wide hips, whale-tail spoiler, and turbocharged flat-six, the 930 was known as the 'widowmaker' for its treacherous turbo lag and snap oversteer. It's now one of the most collectible Porsches.
Powertrain: The 3.0L turbo flat-six (256 hp, 1975-1977) evolved to 3.3L (296 hp, 1978-1989) with an intercooler added in 1978. The 930 was only available with a 4-speed manual — a 5-speed would have reduced the turbo lag's lethality. The 930 S (1986, 330 hp) and the Flachbau (slant-nose) are rare variants. The 1989 model was the last year before the 964.
What to look for: Rust is the #1 concern — check the battery trays, floor pans, kidney bowls (behind front wheels), and rear suspension mounts. The 3.3L intercooled engine is the more reliable choice. The 4-speed gearbox is robust. Matching numbers are critical for value. A PPI by a Porsche specialist is non-negotiable.
About the 930
The 1975-1989 Porsche 911 (often referred to as the 930 generation for its turbocharged variant) encompasses the 911 SC, the 3.2-liter Carrera, and the legendary 911 Turbo. Body styles include the coupe, targa, and from 1983, the cabriolet. All models are rear-engined and rear-wheel drive. The SC used a 3.0-liter flat-six, later replaced by the 3.2-liter in the Carrera; the Turbo employed a 3.3-liter intercooled engine. Transmissions were primarily 4- or 5-speed manuals, with a 4-speed automatic available on the Carrera.
Compared to the preceding 1974-1977 911, this generation introduced galvanized steel bodies for improved corrosion resistance, revised bumpers, and the SC’s enhanced reliability. The 1984 Carrera brought a more powerful engine and a refined suspension. The 930 generation suits buyers seeking a classic, analog 911 experience without the electronic complexity of the later 964 and 993. The 911 Turbo is highly collectible, while the SC and Carrera are praised for their robust mechanicals and engaging driving character, making this era one of the most revered in the 911 lineage.

Frequently asked questions
Is the 930 a good investment?
Clean examples have appreciated significantly and are likely to hold value. But maintenance and restoration costs are enormous. Buy it because you love driving it, not as a pure investment.
Can I daily drive a 930?
It's raw, hot, loud, and challenging to drive in traffic. The turbo lag makes city driving tedious. Most 930s are weekend cars. The 964 or 993 are more practical daily classics.
