I bought some injectors a while back and now I finally got around to putting them in my turbo civic... how can I tell if these are really 345cc injectors or if they are just 240cc. I know they are obd1, and had brown plastic tops/caps/floaters.

 

They have a blue dot on the back of the "clip" housing (under the fuel rail) and blue & green markings on top. Also, the bottom part of the injector is dark gray/black (pintle needle housing).
