As I recall, CIS runs a higher system pressure than needed for Motronic. 3B/AAN is something like 3.5-4 bar?
A CIS system may be 5 bar or so. Why put in a bigger pump than needed? I'm pretty sure you won't need it; Bosch should list the specs somewhere.

Subject: [Es2] Fuel pump pressure
I had an interesting fuel pump morning on the way into work. It hiccuped and then got extremely noisy. So noisy that I could hear it easily inside the car....and outside it was insanely loud. I said a prayer, turned the radio up, and just kept driving. I was able to get to work. When I rolled down my window to badge into the lot I noticed that everything sounded fine. Once hear at ol UPS I shut the car off and restarted it. It ran so I think I'm ok, but I will be changing the pump once the 20vt motor goes in so I've been thinking........
If the pump is on it's way out I want to go ahead and upgrade to what I need once the new motor is in. My question is, I want to change to a 993 turbo pump (325lph) and wondered if it would affect running my stock 4kq? Can the stock accumulator compensate for the extra flow, if any? I say "if any" because I don't know the flow rate of the stock pump vs. the Porsche pump. I would think so, but wanted to bounce it off you guys and see what you thought.
Tom still CIS for now Saltino
