Introduced for the 1978 model year, the 911 SC (Super Carrera) consolidated Porsche's lineup by replacing the 911S and Carrera models. It used a durable 3.0-liter aluminum flat-six that initially produced 180 hp but was upgraded to 204 hp for 1981. The SC was so popular that it's often credited with saving the 911 program from being canceled in favor of the front-engine 928.
The SC is a sweet spot in the air-cooled 911 timeline, blending the classic driving experience with significant usability improvements. Its galvanized body offers better rust protection than earlier cars, and the 3.0-liter engine is known for its longevity once common issues are addressed. These cars are a popular and relatively accessible entry point for enthusiasts new to classic Porsche ownership.
With over 900 recent sales and an average price around $56,000, the 911 SC market is well-established. Prices are highly dependent on condition, mileage, and service history rather than specific options. While top examples can fetch over $200,000, driver-quality cars remain attainable, offering a lot of classic 911 for the money.
Buying Tips
- Check for records of updated timing chain tensioners; the factory design from this era is a known failure point.
- Ask if the original Dilavar head studs have been replaced with steel studs, a common and critical update for engine longevity.
- Even with galvanized bodies, inspect for rust in the kidney bowls, battery boxes, and around the front and rear glass seals.
- Look for oil leaks from the valve covers, pushrod tube seals, and the engine's "triangle of death."
- Ensure the heat exchangers are intact and not rusted through, as replacements are expensive.
Prices range from $2,500 for project cars to $275,000 for exceptional, low-mileage examples.
