i dont think that is right a standard pump in good condition will flow about 3.9 litres a minute and grey injectors will only flow about 2 litres a minute so why do you need a bigger pump??
i don't think so
a cossie pump will probably move that amount of fluid off of the car(if its new and you get the amps to it), however, you have a fuel filter, frictional loses down the lines etc all to reduce its volumetric efficiancy
your car, your engine, your risk......for a couple of hundred quid, i would rather know my engine is getting all the fuel she wants

For that kind of conversion i woiuld also uprate the wiring to the fuel pump.As why spend all that money and let over 10 yr old wiring ruin it.

Depends on teh boost obviously
Add boost to fuel pressure static and theres your answer.

to sum it up, the escorts pump needs uprating without question at about 330bhp,
at what point does the saffy pump need uprating??? will i be alright , there seems to be some cofusion between wether or not 400bhp is achievable with a saffy pump

The Strut Brace...the 2wd pump is not suitable for the turbo you will be using....it needs changing from 350bhp (you can get around 385bhp but its not a good idea unless its brand new) to the 044.

better to get a new 044 and know you have a safety margin, imo
