PORSCHE Turbocharging System: Description

The turbocharger used on the 924 Turbo is mounted on the right side of the engine under the exhaust manifold. Components include the turbine, compressor wheel, rotor shaft, bearings and housings. See Fig 1. A wastegate, located near the right side of the bell housing prevents excessive boost pressure. Should it fail, a boost pressure safety switch turns off the fuel pumps.
