I was looking for answers for a friend that wanted to use the coil on plug system(COP) on a D16. I told him of the two main problems behind using it, the ECU being OBD2b and the provisions for the ECU to monitor the engine(cam sensor). I saw that the a2 had what looked to be mounts on the head for a dizzy, like the older D16 heads. Is this true? And if so does this mean you could use a cam sensor from the D17 on the D16? I figured he could swap in the harness from a '01 ex and just swap in the plugs he'll need to keep from the old harness. I thank he is just searching for answer's to care his momentary boredom, and I'm answering them to care mine. I don't think he'd ever does this, we both know the gains aren't worth the draw backs but would like to know if its possible....
