I have a 1998 civic ex with the single cam vtec will injectors from a 99 civic si work in my car or are they bigger than the ex injectors?

 

Anybody with any suggestions??????????

 

they should all(stock) injectors be the same. they should be 240cc...the only ones that are different are prelude which i believe are 270cc or 290cc i cant remember off the top of my head.

all the difference in the injectors/fuel is the ecu fuel maps and probably the duty cycles. ..... i think
