Like the post above me said. Its not goddamn Vtech. its VTEC. Valve Timing and lift Electronic Control. Anyway, no not all Civic Ex has VTEC. You have to pay extra for it to make it a VTEC, because it's an extra option. You should know your engine has VTEC if you get a boost at high RPMS or if you open the hood, it should say VTEC.
