There is no upgraded ignition system for the 3G RS/GS right now. I did have a talk with a Nology rep about 2 months ago, and they told me that it would be possible to convert motorcycle coild for use on the engine, but that some customization would be needed.
Using their coild and wires would result in a gain, but not really all that much. The stock ignition system is fine until you are ready to move to the full standalone system.
