i just installed b&m fuel pressure regulator
i need to know if the fuel pressure i have is too long

at idle its at 32 psi

the mods are the 3 basic bolton's and a skunk2 im

on a b16a in a 94 hb

 

Set it to 46 or 48 psi (with hose off fpr) and see how you like it.
32 is way too low. Stock d15b's are higher than that.

If you go past 50 i'd start looking for a new fuel pump

You're supposed to install the gage and check pressure before swapping fpr's.

 

really you should have checked the pressure before the install... but i disagree with the last post. i think a b16 with bolt-ons... 46psi is too high. on my 1st gen b16, the OE regulator was set at 28psi. i just smacked it a few times with a socket and brought it to about 36psi. most of honda's motors run in the 30-50psi area, and i doubt you'd need upwards of 50psi with mild modifications. just go with 36psi or so until you get to do some dyno runs.

oh, so all ITR's should replace their pump? how about NSX? both run over 50psi from the factory. the older NSX's have closer to 60psi, if i remember correctly.

The guy has a 94 hatch. i'm assuming the pump is the original one. i have an 88 w/b16a and when i was running 46 psi i decided to get a new pump because it had 215,000 miles on it with with an increased load. Considered it preventative maintenance.

i'm not surprised that the nsx/itr run 50 psi+ from the factory. This guy doesn't have an itr or nsx fuel pump in his car. What's the max psi you think his pump can handle?

Stock fuel pressure is 35-41 on 1st gen b16. I need 50 psi with my mild modifications.

Why would the guy run stock pressure with those mods when he has a adj fpr?
It should be minimum of 41 psi. I'd say start at 44 and go from there.

 

ya its a stock fuel pump

i was jump curious as to what the stock settings are

until i get a dyno on it i'm pretty much just blindly guessing

but 36 psi must be better than 32

i'll try 44 psi but i'm skeptical about raising it any higher
