I'm a little confused, are you still trying to see if the coil packs are bad? If so, the quickest way to find out would be start the car and then disconnect one coil pack at a time. If there is no change in engine idle when you disconnect the coil pack, thats your bad one.
Also are these the same coil packs that are on R33 and R32 skylines? If so I should be able to track down a set of used ones for fairly cheap. Anyway let me know.
