[s-cars] Fuel pump question: V8 vs UrS vs V6

Sorry to be a broken record but:  I have learned (been told) that the
OEM S4 fuel pump (8A0 906 091 G) is the same 43 millimeter diameter one
that the 2.8 L V6 100 used.  Hmmmmm.. not encouraging.  I have also
learned that the 60 mm diameter Bosch Motorsport fuel pump (0 580 254
044) may a)  also be a Porsche 944 Turbo S fuel pump and b) fit into a
92-94 Audi V8 fuel pump mount ("reservoir") (895 201 779H) with some
minor mods and an Audi V8 fuel pump strainer (895 201 531 A) (and
assorted banjo bolts and washers).  If this is all true, then why
wouldn't I just go for an Audi V8 fuel pump (if the pressure and flow
specs were up to it - I figure I need at least 90 psi and 5 x ??? cc/min
at 4.0 Bar (I need spec's for the RS2 injectors at 4.0 Bar))???
