y are u gonna take out the b18b for the b16? for vtec? and if i remember right, the b16a1 is obd-0 with a cable tranny, yeah ur in for alot of wrk for nothing. get a gsr head and golden eagle ls vtec kit and do ls vtec for alot less trouble and more power than a b16 swap. or just get a b18c1, that would be ur best bet.
