anyone know anything about these?? with stock engine…
i set my fuel psi at 20 it still bug out…???:dozing:
your fuel psi should be at 40-45 psi with the vacum off the regulater.set the ecu first…it wount idel with just a stock ecu.you need a afc or some thing to controle them…
Why do you need 450cc on a stock engine?
heres something u should know…u dont need 450cc on a stock motor.
stock motor hp 140 x .50 (NA) or .60(Boost) / 3.2 = ( ? ) x 10.5(convert from lbs/hr to cc/min) = ideal injector size…
ex. 140 bhp x .50(NA) = 70 / 3.2 = 21.875(lbs/hr) CONVERT TO CC x 10.5 = about 230cc is good enough…got it…good…does this even help?..anyway 450cc injectors do no good if you dont have the proper regulator, fuel map, bigger bore fuel rail…ur just gonna run rich…
that eqation gave me a headach:english: :english: you need thuoghs injectors to turn up the boost. stock injectors with fmu=yes 450 with fmu=no 450 a regulater and fuel man…=yes …were do you people read this crap from ? stock injectors with fmu is unsafe becouse of all the hoses and calmps invalved thay tend to bust after awhile .i know couse my homies si burnd to the ground ,and i work at a turbo shop.1000hp supras in the shop i think i kinda know how 2 run boost
i ran my stock injectors with a FMU and its fine to me, because i baby it =)

a larger bore fuel rail isn’t necessary until you hit somewhere around 500-ish at the wheels.
several members of the full-race folk have fairly modified cars, most putting out 400+ and use stock fuel rails. 
that is true my friend =)
FMU’s??? fck people still run these pieces of sht??? wow come on people. walbro 225lph and a chipped ecu will run them just fine. chrome FTW. u guys gotts stop with the ghetto fmu’s already. they are complete junk!!!
don’t hold back bbp, tell us how you really feel. :giggle:
(and i agree 100%)
just puttin in my 2 cents, and i got that from import tuner…ahahha…
Do G2s have a resistor pack already? In conjunction with that, and FMU and 450cc injectors mean a washed out piston rings.
90-91’s do.
