I have heard mixed reviews so far, and i need to know if i need to buy a fuel pressure regulator like an aeromotive or aem one or not. My setup is an F22A6 (out of 92 accord), fully built block and head, gonna be running around 430whp, around 24 psi. Using 750cc injectors, and a 255lph walbro High pressure fuel pump. Is my stock honda one gonna be alright for my setup? Thanks!

those injectors are enough for your power goals, there shouldnt be a need to change the fuel pressure regulator

aleks77

ok so when do you need a fuel pressure regulator? when u use smaller injectors?

Adriano

I would def. get a FPR. That way you know your fuel pressure is consistant everytime, specially if you are running an after market pump.

hmm thanks, any more input?

aleks77

anyone? need more opinions

boostedcivicsir

the reg may be able to handle it, BUT if you do need a little base bump the stocker cant do it. and the BM command flow is JUNK. if you feel you will need a bump in base pressure, just get an aeromotive with the -6 ports. /done

if you had 880s i would say go stock. but you might want to think about getting an adjustable one for pushing those 750s.

i havent bought injectors yet, should i go with 750cc and a FPR, or 880cc and stock? whats better? Isnt my idle gonna be a little shitty with 880s?

0morgan@synapse motorsport

idle shouldnt be an issue with 880s.

the 880s will require a resistor box, which is its only disadvantage but its a lot cheaper than a FPR. an FPR is always handy to have, its not required by any means but its a suggested upgrade.

made 510whp on stock lines and stock FPR on 880cc injectors it ran perfect and idled fine

this was on a 255 intank

no need for it spend your money on trannys...

i have an accord which uses peak and hold injectors, am i still gonna need a resistor box? i thought that was only required for cars that dont use peak and hold injectors stock

boostedcivicsir

if your car has p-h injectors already then you are fine. make sure you still use the box.

aleks77

if you say im fine, then why do i still need to use the box? lol sorry confused

Si Shane

Peak and hold and saturated injectors are sent different electrical signals. The larger injectors are not available as saturated. If your EMS supports low impedance injectors (peak and hold) you can run them right out, otherwise you need to use resistors inline to 'simulate' a peak and hold drive style.

If you currently have peak and hold injectors then go with the bigger ones. If you currently have saturated injectors go with the bigger ones, because the fpr is not needed and is more expensive than 4 radio shack resistors. (IMO they solder in cleaner and are cheaper than a resistor box).

if you have peak and hold injectors in there stock, then there is already a resistor box in the car, so you dont need to purchase/install one.

aleks77

ya my accord does use peak and hold stock. So i should go with 880cc injectors and stock FPR? and 255lph high pressure or regular pressure walbro fuel pump?

I went with the low pressure, that's what I have found through searching. I also know that some people recommend using the high pressure.

I think you should be fine with the low pressure, but wait for another response.

Everything else you listed off seems okay to me

aleks77

any more input?

Si Shane

Try searching, 5 years worth of input there.

aleks77

i did try just find mostly stuff for sale, any more input? Thanks!

Use the archived feature, and pick a forum (not for sale forums). You have a boosted car? You posted in Forced Induction? You ONLY wanted people in this forum to see your post, yet you don't dare to restrict your search to this forum?

You can search in every forum, uniquely, before you will get a number of useful responses to your thread.

Get the low pressure or high it doesent matter dont worry about a fpr run stock **** and be done
