EF is the chasis code for the 4th gen civic and second gen CRX in Japan, the 8 indicates a CR-X SiR, which is the top of the line model, power windows, leather interior, glass top (some of them), b16a engine (160HP), different front end, ect... Just a better over all car, as far as options go, and the EF9 is just the Civic hatch version of the EF8...

Hell, even the JDM Si's (EF7) got alot more options than we did in ours... The DOHC ZC engine for starters... But we get stuck with the crappy SOHC 108HP version of the ZC... :angry:
