what all would have to be added when going from a 1.5l to a 1.6l vtec(d16z6). i know that a wire for vtec will be needed. is there only one wire for vtec. but i dont know about everything else.

ok now that thats out of the way. i have a del sol si. im droping a ls vtec in it, so everything is coming out. my friend just bought a del sol s for $600 and he might want to buy my old motor. thats why im asking what will be needed.
