i would honestly get a z6 head and intake manifold to put on it...the intake manifold you have will work but the one from a z6 makes it breath a little better...you will also need an ecu to put in it for the vtec...and you can have someone wire in your vtec for you so you dont have to change out your harness...im going through the same thing you are...if i left anything out just look up info on the mini me swap
Vtec is controlled by the head. You need a vtec head. So either need a z6 or y8 head. Your also gonna head the intake manifold, distributor, vtec solanoid, z6 timing belt and p28 ecu. I'm sure I'm missing a couple parts. Just Google d15b7 mini me
