i have a 97 civic dx(non vtec) i want to change the fuel injectors to a way bigger size but i was told my current ECU would not be able to use injectors bigger than 310cc. is this true. or can i just change the rail,wire plugs and pressure regulator and put on the bigger injectors?

 

unless you have boost or serious mods why would you want to?

 

thats exactly why i want to, i'm plannig on pumping alot of air into the engine, and i need the fuel to keep up, i'm just confused about how i can do that. i'm not sure if i need the ECU to be aware that i've physically modified my fuel settings or if i can just put it all in and hope a new fuel regulator will take care of it.

 

how exactly are u adding more air to ur engine? (boost or internal build-up?)

 

unorthodox methods that i'm sure you guys wouldn't approve of. i have an AIT modification(on the intake that reactes according to my throttle instead of actual engine temp), i have a foam intake system with an electric blower mounted on. my air cfm is in the 900 when the blower is on.i need more fuel than what my stock parts can provide and i'm wondering if my ECU can handle a fuel rail,injector,wire upgrade, because soemone told me it can't

 

that is def. some crazy stuff u got going on there. my advice would be for u to go a more traditional route of either turbocharging or building the internals of ur engine. the method u are using sounds risky and therefore could harm ur motor.
To answer ur question no ur ecu cannot handle bigger injectors. it is programmed to work with the stock injectors.

 

so what should i do with my ECU?

how can i get bigger injectors to work on this non vtec motor

i definatley know the risk to my motor but the way i see it i got jipped the minuete i bought a dx 97 engine. so i'm gonna push it. worst case i can always do an engine swap and really get going.

 

just run the stock injectors they will be more than enough for your electric fan

 

ok(like i said i knew the idea of a blower would be unpopular here) but in the case that i just would want to upgrade my fuel injectors what should i do

 

get some rc 270cc and those will be just fine for you
