Porsche Supplies New Engine Parts for Classic 911s

New Magnesium Crankcases for Carrera RS 2.7

Rejoice, Porsche 911 owners from 1968 up to 1976! The iconic German car manufacturer has announced the availability of fresh magnesium crankcases direct from the factory.

These latest cylinders can be bought for F and G model cars paired with 2.0, 2.2, 2.4, and 2.7-liter engines, counting the iconic Carrera RS 2.7. The illustrious RS marked its 50th anniversary last year, in which recognition Porsche revealed a restricted-edition type of the current 911 GT3 RS.

Porsche declares that these crankcases can be procured from any special Porsche Classic collaborator or a flagship Porsche retailer.

According to Porsche, they decided to reissue this component in light of the struggles that owners are facing while trying to keep their classic 911s up and running. To-date, owners have had to either get welding done to repair any cracks or resort to utilizing parts from crash-damaged vehicles. Neither approach is viable as a permanent solution considering the immense pressure that a crankcase endures – even minute flaws can lead to complete disintegration of an engine.

“This reissue closes yet another hole in our selection of spare parts, allowing us to assemble fresh engines for a majority of vintage 911 models,” states Ulrike Lutz, Director of Porsche Classic. “Our customers are eager for genuine engine components such as this one.” Porsche Classic is already in the process of replicating crankcases for other iterations of the 911.

This recent undertaking for Porsche Classics was substantially more intricate than constructing aluminum crankcases for cars from after the 1990s. Initially, Porsche had to fabricate blanks and achieved that by manufacturing anew a motor for competition from the Porsche 962. However, the engineers needed aid in comprehending retired schematics containing production facts. To answer this, they delved into Porsche’s item inventory, applied the data on hand, and even acquainted with ex-employees to get answers.

Once the occupation was accomplished, Porsche employed modern manufacture procedures. They distribute CAD information to a third-party provider who utilize sand moulding. After the casting, in excess of 50 distinct cutting, boring and milling appliances are used to extract roughly three to four-hundredths of a millimetre.

To ensure optimal performance for the crucial Carrera RS 2.7, 3D evaluating probes are employed to scrupulously inspect the crankcase with over 1300 examination criteria in mind.

Because it is Porsche, they subjected the new crankcase to rigorous testing and examination before they go-ahead with its production. Installing a magnesium crankcase along with various sensors on a 911 Carrera RS 2.7 test bench, the automaker captured numerous oil samples throughout the entire trial period. Once the analysis was finished, Porsche Classic engineers, in addition to Weissach specialists, dismantled the entire engine completely for a comprehensive inspection.

Since 2013, Porsche Classic has been producing about two hundred elements each year. These range from motor parts such as the crankcase referred to herein, to upgrades in their infotainment systems, catering to a more enjoyable experience when driving a vintage Porsche car.
