(a) - Yes. Add hi-comp pistons, and hi-performance camshafts as well.
(b) - If you already had the zorst, airbox and flatties, then its just hi-comp pistons and cams, if you want the *maximum* benefit of the Dyna.
Where do you put it ? Wherever it can fit - generally they get mounted near the battery box/underseat area. The actual physical size of the ignition module is not that big - not much bigger than a pack of ciggies really.....they can be squeezed in just about anywhere, as long as they are not located to close to heat sources (above the motor or near the zorst).
