Let’s talk about the 1970s Porsche 911 for a minute. Why? Because the 1970s Porsche 911 is a collector car that deserves much respect. It’s the longest-running model from one of the most iconic sportscar producers in the world. And it’s one of the most recognizable vehicle designs in automotive history.
The evolution of the Porsche 911 began in the 60s but was perfected in the 70s. By the end of that decade, Porsche would iterate the 911 design dozens of times, making huge leaps in car engineering. The dedication to creating a great sports car with the 1970s Porsche 911 propelled it to become the best-selling luxury sports car of all-time.
The now-famous and very distinct design of the Porsche 911 was introduced in 1963. Since then, it has been continually developed through numerous versions and series. Ferdinand Alexander Porsche, the founder’s grandson, was heavily involved in the original design that led to the 911.
1970 Porsche 911 T
In 1970, Porsche released the second generation 911 called the C Series. While the body style didn’t change from the original 911, the 1970 C Series saw engine changes to a 2.2-liter flat-six engine. The wheelbase increased just a couple of inches, but the length remained the same as the original 1960s version.
Three different 1970 Porsche 911 models were produced, the 911T, 911S, and the 911E. The E and the S were fuel-injected, while the T was carbureted and had less horsepower than the E and S models.
You will find many Porsche purists prefer the “T” base model for its stripped-down features and minimalistic driving experience.
1970 Porsche 911 T For Sale
The base model 1970 Porsche 911 T can be found selling for anywhere between $30,000 and $70,000, depending on the condition. Of course, an original, well-preserved car will be valued significantly higher than a decent looking rebuilt car.
When shopping for older 911s, engine condition should be one of your primary concerns. Numerous potential problems could lead you to poor performance or an entire engine re-build if not inspected properly.
One common problem found on the early Porsche 911s is rust on and rotted areas in concealed spaces that are not visible to a quick glance.
Above the rear tires on the inside of the lower body will be one of the first places rust will have began to make its way through. As for rot, there’s a common area below the rear window that tends to disintegrate first. Check these areas carefully for signs of trouble.
Most older 911s will have had some work done, but it’s important to inspect the quality to be sure it was done correctly.
Check the panel alignment for tight and uniform spacing. If you’re in the market for an early 1970s Porsche 911, take your time and ask many questions. Don’t be afraid to negotiate the price when you’ve identified areas of concern on the car.
1971 and 1972 Porsche 911
The 1971 Porsche 911 models received a new and larger 2.4-liter engine from the 2.2 liter. Slightly higher horsepower also accompanied all models.
Porsche realized there were handling concerns, and in the 1972 Porsche 911, the first changes were made to address these issues. The design team relocated the oil tank to the front of the rear wheels, which improved the weight distribution and handling.
A 1972 Porsche 911 will feature an oil filler door on the right rear quarter panel because of this change. But after just one year, the oil filler door was moved back to its original location due to people confusing the oil door with the fuel filler door and accidentally adding gas to the oil tank.
1973 and 1974 Porsche 911
The 1973 and 1974 Porsche 911s introduced the Carrera model with a fuel-injected engine and much more horsepower. The mid-70s saw increased safety regulations, so Porsche found ways to integrate these features in the 911 design. A new raised bumper for crash test standards and a three-point safety belt was included.
The 1974 Porsche 911 featured the original Turbo with a 260 horsepower engine and a 3-liter engine. The new engine was highly efficient and demonstrated that Porsche was serious about delivering performance to the 911. The was also known as the beginning of the fourth generation Porsche 911.
Values for the 1974 Porsche have steadily risen over the last few years. Total production volume was just 4,014 cars in 1974.
Tightening emission standards caused issues with the engine design where some cars had chronic overheating problems. Engine problems and rust and rot issues made it difficult to keep mid-70s 911s on the road.
Modern-day mechanics are more than equipped to tackle the issues that plagued the 1974 Porsche 911 engine, but it will cost a pretty penny. Values for a great running classic 911 reflect the expensive expertise required to restore and maintain these cars.
1975 Porsche 911 Carrera Turbo
The 1975 Porsche 911 Carrera Turbo set the stage for extreme performance on the race track, but car enthusiasts also flocked to the newly amped-up version of the 911. Values for a 1975 Porsche 911 Carrera Turbo can be as high as $200,000 to $300,000 for an original, numbers matching, fully restored model.
The whale-tailed, flared-fender design of the 911 Turbo was an instant classic. In August of 2019, a 1975 Porsche 911 Turbo Carrera was sold at an RM Sotheby’s auction for $285,000. It was just one of 274 first-year Carrera Turbo models and was completely restored.
The original 911 Turbo models symbolize Porsche’s ingenuity and leadership in automobile design and engineering. The mid-1970s laid the groundwork for the enormous demand Porsche would see for its 911 Turbos in the 1980s.
1976 – 1977 Porsche 911
Few changes occurred in the 1976 and 1977 Porsche 911 design. Engine performance specs remained the same, and body changes were slight. One thing that would help preserve future 911s from corrosion was the addition of an entire body made from galvanized steel, which increased rust protection.
In 1977, all Porsche 911 engines complied with strict California emissions standards. Only 2,449 911 models were produced, and the Turbo Carrera models saw just 727 left-hand drive, North American cars sold.
1978 – 1979 Porsche 911
The trouble with the 2.7-liter engine in the 1975-1977 engines led Porsche to a new, much more durable, and powerful engine. Changes arrived for the 1978 Porsche 911 Turbo with increased engine capacity from 3.0 liters to 3.3 liters and an intercooler to the engine, which produced 300 horsepower. The ‘whale tail’ spoiler at the rear was also raised slightly to make room for the engine upgrades.
Porsche produced 5,178 911 models in 1978. Prices for an excellent condition 1978 Porsche 911 Turbo can reach well over $100,000. With a base price of $37,000 in 1979, the 911 Turbo was quite expensive but delivered an incredible driving experience for car enthusiasts.
The 1980s saw ever-increasing Porsche 911 popularity with quicker acceleration, performance, and luxury features. Slight design changes were made to accommodate engine upgrades, and overall engine reliability improved with new fuel and ignition components.

The Porsche 911 has become one of the most successful luxury sports cars in history with its world-renowned design and durability. Since the early 1960s, Porsche has sold over one million 911 models.
