Honda's Vtec is capable lift/duration by swapping in a completely independent set of cams at an RPM. Also, the new iVtec can control phase angle as well. Read about it

that's only possible when using the dual cam system, vtech systems found on 1.5l engines dont have dual cam system and don't change the cams but only advances and retardes the cam on its engine. for example, the stage 3 vtec found on the 1.5l honda vtech engine advances the cam at 3.5k and advances it again at 5.5k, other stages of vtec's will advance the cam at only one point
