Space? Ease of fabrication? I tried putting my four injectors 21 inches away from the port myself and found that while I could not tell any difference in power( up or down), I found a distinctive hesitation bog if I opened the throttle quickly. Also it was hell to start on a cold morning. But, a PP port may be a different animal in those regards - actually cold starting should be OK as any liquid fuel will flow down hill. With my plugs up it has to flow up hill {:>). Good luck, we are all eagerly awaiting the results and I have two almost new rotor housings just waiting.
