fuel pressure psi help

[lilaznjeff]

hey guys i have sr20de na, with a semi build motor, after starting up from the build. i knowtice my PSI went to 19psi.
i know i would need bigger injectors, but runing on 19 psi isnt not safe. my question is
if i have a stock ecu.
and i run bigger injector will the fuel pressure regulator control it?
or would i flood my motor /

EDIT: ok wait i don't think i understand your question, i read it again and im confused now.. are you worried about the 19psi? or about running bigger injectors?

i know from some of my friends that after a few runs, sr20de and sr20ves tend to lose some fuel psi, don't know why i never really checked that out since i have never worked on one of those engines... are you running low PSI always or sometimes?

and if you are running low psi check your fuel pump and just for the heck of it... your regulator should be checked to...

my fuel pressure gauge gave me a reading at 19psi
since i have semi build motor, should i be runinng bigger injectors,
and if i run bigger injector at 33 psi would it possible to flood the motor

yeah, probably, with stock regulator and no tune... you will flood it

how big are the injectors you want to run? some people run tuned engines with a bit bigger injectors and a upgraded fuel pump and just adjust a bit with aftermarket regulator...

what is "built" engine mean for you... what mods, and that would help out what injectors you might need...
