Did you read below? You've got to understand Subaru used the pump they did to suit very low RPM flow rate requirements and not the 7000 rpm requirements.
The issue if you go to a smaller pump is you'll very likely over heat in traffic while idling or at low RPM. It's very hard to get a mechanic pump to do both nicely as we know.
