from memory S13 SR20DET injectors are about 380cc/min, I didn't know RB25's had those gump looking injectors too. :confused:
from what i remember s13 & s14 flow 380cc and s15 flow 430cc
it probly will be just as cheap to get a new fuel rail and 550cc injecters only if your going to tune your computer ive had a qaote for 700 fitted
i think S15 injectors are actually about 480cc

Hey AKA180 where did you get the quote???? Need injectors so more boost.
GTi-R injectors are, AFAIK, 430cc.
close, 444cc but top feed, different fuel rail.
Just remember the S13 injectors are High Impedance Side Feed. They aren't top feed like most injectors are.
Hence, it's friggin difficult/impossible to find cheap injectors to slot right in.

yeah the rb25 and sr20 ones are the same I've had a quote of around 240-250 each for 550's or 740's nismo in japan sell then for around 14 000 yen each not cheap but will a power fc run a custom fuel rail?.
Power FC should run the custom fuel rail. All it has to know is what cc the injectors flow. Unless your messing with fuel pressure when you customize the fuel rail.
www.horsepowerinabox.com should provide you with all the stuff ur in need of (sorry if I'm not meant to post private business names in here), but it's just answering the questions sorta
the custom fuel rail will be needed for almost all injector conversions down to an sr20det, since, as 180sx said, they're side-feed and high impedence
bosch produce an alternative, in 550cc intended to slot right into the sr20, however they have a pretty hefty price tag. A set of 550cc from a 13b (I *think*) and the fuel rail with a fuel regulator or powerfc, would be a better option
