Will I need a fuel pump?

Hey, Im going to be running a prelude h22 turbo. I am going to use 450cc injectors and was going to do a fuel pump as well. Will i need a fuel pump? i only want to run 7psi for now, and will be using a SAFCII to control the injectors. I have heard of people using stock fuel pumps and just upping injectors. Is this ok?
Thanks

it's 80 bux for an upgraded fuel pump. do you really want to chance blowing up a motor over not wanting to spend 80 bucks and like 20 minutes of install time?

i know i read somewhere that most honda pumps are good to 300+ hp at stock fuel pressure, but for exact figures someone else will have to chime in. i have a 255 intank, its easy as hell to put it in, good insurance/piece of mind

if you're running an h22 why not use a VAFC? unless you already have the SAFC bought

no you don't need a new fuel pump with 450cc injectors as long as your stock pump is in good shape... Highly recommend changing your fuel filter though... also... inline pumps are for suckaz so don't consider that

i doubt the pump will have any effect on mileage since you can control the fuel with the afc, thats what dictates your mileage; that and your right foot
