okay, my friend swapped in a motor. the block says ZC, but the valve cover that it came with is from a crx si. its a sohc motor, and when we looked, there was no vtec solenoid. we looked at the cam, and noticed that there was a long cam looking cylinder above the cam, and it had a spring attached to it. is this car vtec? because i only know of a sohc vtec and dohc ZC.
