Can anyone tell me what the stock fuel pressure is on a 93 civic ex with a D16Z6 P28 ecu is? And now that i got my self a FPR what is a good pressure for 10 to 15 psi boost?

 

i want to say 35-37 ish?
stock. use it if you want, what FPR is it? b and m command flow? if it is anything that you have to cut the top off of the stocker, sell it. the stock reg is good for more power than you will prob. make at that boost.

 

this is the FPR i bought its pretty decent i have herd good things from a few ppl.

specifications i found

vacuum connected 30-38
off vacuum 40-47

 

whats that mean vacuum connected 30-38 off vacuum 40-47

 

you hook a vacuum line to the FPR. with the vacuum line connected its ____ with the vacuum line disconnected its______

 

ok i will be haveing the vacc. line connected .... so 35ish should be good? and what was stock fuel pressure anyone know?

 

the specs i gave you are stock

 

set it to where when you pull the vacuum line off at idle the pressure goes to about 45. then when you connect it it will go down into the 30's that should be just fine.

on boost. it is more based on what happens while tuning. if you run FMU it dont really matter if your tuning the tuner will set that for ya

 

what kinda Fuel press. should i have it at fo 10-15psi boost ...... i have 550cc rc inj. and stock fuel pump ( will that stock pump even keep up with 10-15 psi boost) Thank you guys for helping me figure this out by the way. most ppl on here will jump a man if ya know what im sayin thanks

ok here is the deal.

line on = no rise in fuel pressure. idle.
line off = atmospheric pressure. wide open throttle fuel pressure. remember there is no manifold vacuum at wide open throttle.

the line off method is for setting what we call base fuel pressure. it is the highest it will be without boost acting on it.

if you are goin turbo on the stock pump, it is a matter of time before it or your engine will expire. replace it with a walbro.

 

Ok what if i run the FPR at 45 when vacc. is connected will that be ok also?

 

pointless.

ARE YOU GETTING TUNED?????

 

you shouldn't be running boost on stock f. pump, period!

no because that will be like 55 off and 70 when boosted.
replace the pump, leave the reg alone. thats what i would do.

32 bucks for a reg and gauge, its your engine. me i wouldnt trust it.
