Porsche Classic Offers New Magnesium Crankcases For Vintage 911s

Vintage Porsche 911 prices may have reached astronomical levels in recent years, but they've had a dedicated following for decades. These folks will invest massive sums of money to keep these air-cooled classics on the road as long as possible. The German carmaker noticed this and stepped in with Porsche Classic, a department within the brand dedicated to manufacturing new parts for these old rides to extend their lives almost indefinitely. Today, the carmaker announced another effort in this pursuit, this time in the form of new magnesium crankcases for 911s built from 1968 to 1976. This covers cars with 2.0, 2.2, 2.4, and 2.7-liter engines, including the Carrera RS. Previously, owners had to rely on welding cracks or sourcing parts from other cars. However, aside from reproducing these crankcases, Porsche Classic went to great lengths to perform durability tests to ensure their stoutness.

These new crankcases are sand cast using CAD data and then machined on a five-axis CNC machine. Porsche claims it uses up to 50 different tools for the job, attempting to remove as little material as possible. Once completed, a 3D measuring probe scans the crankcase for over 1,300 control dimensions. Porsche Classic Director Ulrike Lutz says, "This reissue closes another gap in our range of spare parts, making it possible to build completely new engines for most classic 911 models."
