Complete Engines for Porsche 911

The Evolution of the Porsche 911 Engine

The Porsche 911 engine is a rear-mounted, flat-six that has been around since 1963. Originally designed as an air-cooled engine, it was revised in 1998. The engine specs have changed over the years; you can find many iterations of Porsche 911 engines for sale on eBay.

You can buy Porsche 911 engines in three basic conditions. First, you can buy used engines. These are offered for sale by the mileage on the engine. Finding one with low mileage on eBay is fairly easy. If you want to buy a Porsche 911 engine with zero miles, you can purchase it in rebuilt or remanufactured condition. Remanufactured engines are also sold used. This means they are remanufactured but sold with accrued miles. A "remanufactured" engine has been tested and approved to comply with original standards. The remanufacturing process is modeled on original blueprints and specifications, versus a rebuilt engine which is usually constructed by a mechanic but has not been tested or approved.

The original 911 engine introduced in 1963 was an air-cooled 2.0-liter, flat-six engine with 148 horsepower. In 1983, it was upgraded to a 3.2-liter engine and later to a 3.6-liter. An air-cooled Porsche engine for sale in a flat-six is available on eBay in 3.2-liter and 3.6-liter capacities.

The big change came in 1998. Construction changed to a water-cooled Porsche 911 3.4-liter, 296 horsepower engine. This means there exist no air-cooled engines after 1998. The water-cooled engines are offered in 3.4-liter and larger capacities. On eBay, the larger Porsche 3.6 engine is for sale.

In 1975, the first Turbo engine was introduced. Since 2013, the Turbo has been the standard since its introduction. The 2019 Porsche 911 engine supplies three turbochargers.

The following information points out the evolution of the Porsche 911 engine in the company's cars from 1963 to 2019:

• Porsche 911 (1963-1989) – Porsche 930 Turbo (1975-1989, the first Turbo version)
• Porsche 964 (1989-1994) – Porsche 993 (1995-1998, the last air-cooled 911 engine)
• Porsche 996 (1999-2004, a water-cooled engine) – Porsche 997 (2005-2012)
• Porsche 991 (2012-2019) – Porsche 992 (2019-current)

Generally, no. New engines for the Porsche 911 sports car are no longer sold. Although, occasionally, you may be able to spot one on eBay. The reason they are so difficult to track down is that newly-assembled Porsche 911 engines are no longer offered by the manufacturer. Engine block parts and other Porsche manufactured parts are available on eBay. Foreseeably, you could build your own Porsche 911 engine by purchasing an engine block and building on it with parts purchased from eBay.
