H22aBean: the crossover IS VTEC; it's the term for when the lobes on the cam switch over. I think what you mean is to have VTEC engage when the secondaries runners open up? That's not hard to do - just buy a VTEC controller, and move the crossover point from 4400 to ~5750 or so. The car will be noticeably slower from 4400 to 5800, though... and at 5750 you'll get a big change in volume and performance. You might even spin the tires when it kicks in - I've heard of this happening when you move the VTEC point far enough up.
