The title says it all. Has anyone ever tried this swap? Is this even viable? Purposeful?

What's your reason for wanting to do that?

I would say forward thinking. F series is an upgrade to E series in terms of reliability in some aspects. When an E series N55 HPFP brakes, would it be better to replace with an F series vacuum pump + HPFP?

Do you know which HPFP you have? Some of the earlier ones like mine use the same pump as the N54 and it flows more than the later E and F series pump
