03-25-2008, 01:43 PM
So after looking around (briefly) i havent noticed anything that can answer my question. so here it is i have a sr20det redtop in my car i have the following items.

type rs bov
removed a/c
full 3" exhaust
polished turbo manifold
s14 water pump
custom intake
walbro 255
apexi neo
and new gt2871r dual bb turbo

i am modding my turbo by removing that internal gate and running a tial 38mm external gate with dumptube and im gonna run aprox. 19-20psi thru this set up. and running 110 fuel too.

so my question is how much power can i get from the stock injectors?
im going to get a fuel pressure regulator too of course.

my goal is 300 whp on the stock motor and internals on this setup is that obtainable. im assuming yes but just wanted to know what i can get thru stock injectors.

any help would be great thanks guys.
