a v-tec question

ok currently i have a 1992 prelude SI, and its a dohc engine non v-tec and im wondering if its capable of doing a v-tec swap from a 1993 v-tec engine, if so, then wat is need to be swapped, just the cam gears or etc. someone told me about the camgears can be swapped and etc. but i'm still in the doubt. if you know wat is need to get v-tec onto my prelude si then respond back, it is important!!!
