That is interesting.  Please tell me that the rotation for the water pump for the 3rd generation is oppisite that for the second generation.  I am using a simple belt scheme (everything turning the same direction).  But in your drawing the water pump is turning in the oppisite direction.  Yet I don't remember ever discussing that the pump rotation direction was different on the 3rd generation engines.
