you dont need an rz coil.
so im assuming you have the jugs with exhaust manifold adaptors, powervalves and head.
you'll need a RZ stator assembly, CDI, PV controller (or zeeltronic PCDI-10V), PV servo, and a RZ regulator/rectifier. you will also need a battery eliminator or a motorcycle battery.
not to forget small things like PV servo cables, powervlve housing etc.
im runiing the PCDI-10V and a eliminator, this is my wiring diagram
hope that helps
