You'll need to build the engine from scratch and beef the heck out of it if you want to max out the FIC. I'd love to see you do it so let's see what you can do. If you do, next move is a TEC3 as it is currently the only sub 5k standalone that will do dual plugs per cylinder. If you have deep pockets, a Motec unit would work great but unless you need telemetry, the TEC3 will do everything you need it to and for half the price.
