if you have a 92-95 civic, regardless of trim (ex,lx,cx,dx,vx), you can drop in a obd2 or obd2b b18c motor with no problem. The connectors are the same. ALL you have to do is "reverse" 2 wires for the "Intake Air Bypass" and wire your car up for VTEC (if your car doesnt have vtec).. you dont have to mess with anything else..
