Hi there. does anyone know what the flow rate of the 2001 ej20 sohc injectors is? im just finishing off my supercharger conversion but wanted to know if i should put some wrx (380cc) injectors in? i just dont want it to run lean when im driving it but as the ecu's cant be mapped, i wanted to make sure it wont run too rich at idle or have starting problems. any help / advice is appreciated. thanks, andy.

 

??? You've done a blower conversion on an NA engine but you don't have any standalone engine management? IIRC 380's are generally capable of up to 300bhp but no more, 440's will get you into the mid 300's etc. but that's with proper ECU control and mapping, not just by swapping injectors around... whatever you do, it sounds like you'll need an adjustable regulator and an AFR gauge to get this thing running. And a hell of a load of other stuff now I come to think about it.

 

hi im looking at around the 200-240bhp power band for now. i have adjustable fuel regulator and afr gauge already so will know how lean/rich it will run. was just wondering if anyone knew how the injectors would hold up before i faffed on replacing them. ive decided that if the ecu doesnt agree then i'll take it up to andy forrest and see what he can do. ive heard theres nothing he cant do with ecu's ;-)

 

best solution would mostlikely be some additional injectors driven off an Aquirmist injector driver or similar.

hi. thats a great idea i hadnt thought of running something like that! thanks for the advice. *off to look at prices* :-)

 

with setup they can work fairly well
