What about PS pump reliability? In the 944 many of us use manual steering due to reliability issues of the pump and the belt flying off.

I have heard in the past that tech inspectors have required that if the steering is converted to manual, the entire system must be replaced, ie. the steering reck must be a bonefide manual rack and the pump and plumbing removed. This is what I did in the 944 and it's fine in a Enduro.
