This article describes how to replace the Cayman/Boxster stock oil pressure alarm switch with the dual purpose oil pressure alarm switch and oil pressure gauge transducer used in the Porsche 996 cars. The oil pressure transducer output can then be connected to a standard VDO oil pressure gauge or used to monitor oil pressure via a track data acquisition system (such as the Traqmate) or trigger an alarm using an external circuit to detect the desired alarm pressure level. Many Cayman owners...

There are multiple factors contributing to the PS fluid temperature: high engine RPMs which result in faster PS pump rotation which in turn heats the fluid, and the fact that the PS lines from the pump run near the left-side...
