Your stock fpr will regulate your fuel pressure just fine.
You will need to tune your fuel pulse width via the ecu. Read http://www.phearable.net/tech/efibeginnerguide.html

ok, but my plans where to run some 450 injectors and soder in risistors and that why i would just tune with the fpr, with this not work?

arc_55

no, that will not work because you will need to lower fuel pressure dramatically in order ot get the same amount of fuel volume, but even at that the injectors will have an inefficient spray pattern and will not atomize.

You do not need a fuel pressure regulator and the stock one will suffice and give you realibility much more then a cheaper fpr.

What you need to do is install the injectors and walbro 255 and have the car tuned. Basically during this event you will be telling the computer how much to pulse the injector to get the correct amount of fuel volume atomized into the chamber.

alright thanx

alright one more question i was told you could make the stock fpr ajustable is this true? like by drilling a hole in the top and puting a bolt it it with a nut.

"fpr worth buying"

no.

my friend bub put down 754 on stock fpr and stock fuel rail in his dd boosted gsr hatch. insane, i know. just goes to show you how good some stock parts hold up. but thats bseries.

Hiii Im TYLER

gee... I don't ever remember bub making 754whp. Maybe 730tops, but @ RRev 680. I don't know how many times we have to correct you kid. Get your facts right.

So thats means he should be in the 9s this year rite?

thats the B&M FPR, you mod. your stock one. You really dont need to do anything with it, it works fine to over 400hp with no needs of modding it. its more of a look at me thing under the hood than a functional piece

jdm602

oh really? yea i remember him making 680 at rrev too. either way 730 aint far off from 754. and myles is the one that even told me he made that up at ETS. if anyones wrong itll be myles on this one. you cant argue with what you said myles since everything you say is right.

read above punk.

edit: he made around 730.

gringotegra

he has the mph to get low 10's but his car doesnt hook worth a ****...mid 1.7 60fts arent cutting it! **** with the mph he has some go 9's...but idk if thats going to happen...

Hiii Im TYLER

Im not sure if you were kidding or not, but no. But anything can happen.

HotRodCarrillo

seems like his power is fine just work on hooking the car better
I use to kick it with bub way way way way way back in the day
before he was into hondas matter fact i got a picture of bub and tj dressed up
as girls lol

kulo

so fuel pump/injectors need to change before fpr/fr?

jdm602

yes.
