Im not sure if I completely understood what your trying to say but k24s have Vtec, I think one does not(k24a5 ?) but our a2 does and it is iVtec. There are numerous conditions that are required for vtec to engage 1) enough oil presure 2) 6200rpm (stock) 3) a minimum manifold pressure, 4) throttle position 5) Coolant temp up to operating temperature.
All of these things need to be met before vtec will engage.
If im reading this right did you say you tried to engage vtec on a lift? First of all if you had the car in gear on a lift at 6k thats just insane and stupid. Secondly there is something called CLV or calculated load value. That has a value that needs to be reached as well in order to hit vtec.
