hmm that's about all I have right now

do I need fuel pressure regulator or no? oh yeah this is on stock fuel rail.. if that matters

my goal is to run 15psi on s14 turbo and call it a day.

I see your car is finally coming along, good job man

PS: Hows the sr running now?

Sorry I cant be of any help

[Dattebayo]

Maybe the SR guys would know better?

tomei 555s? it should be a direct fit on the stock fuel rail. why 555 though not 740? you could just tune it to run at a lower duty cycle and when you wanna smash just boost it up.

got a bigger fuel pump? 250lph? dont recommend walbro but it works. my friend installed a denso 260 on his car and its good.

a fuel gauge would be nice too

it'll be better with a fuel pressure regulator without it you may have problems like cold/hot starts and may run rich/lean sometimes. its nothing to worry about too much though.

for 740s i think itll be better to use it with a fuel pressure regulator because you'll want to squeeze more fuel out of it for the bigger injectors.

they are nismo 555sand I have walbro 255

I guess my main concern is able to output enough fuel into the injectors

[Juujai]

if youre worried though you could email the shop you got the injectors from and ask if you need a fuel pressure regulator but you should be fine. 15psi is okay.

pay attention to your oil/water temperatures and oil pressure though better safe than sorry.

one of my friends overheated his sr because he didnt pay attention to the gauges while driving hard
