Racing Beat engineered the 3-Rotor Distributor Cap/Rotor Kit to allow the adaptation of the extremely reliable 1981-85 RX-7 Electronic Distributor onto the 20B 3-rotor engine.
This exclusive Racing Beat 3-rotor distributor kit includes fully machined and assembled distributor cap and distributor rotor, as well as a laser cut reluctor 9-point star wheel. The stock ignitors found on the 1981-85 RX-7 electronic distributor will not function properly for the 20E rotary engine application - their spark energy is inadequate to drive coils directly and they are susceptible to misfire or crossfire problems if used with a CDI ignition (capacitor discharge ignition); however, the magnetic pulse pickup assembly contained with the electronic distributor will trigger a CDI ignition reliably.
You will need to obtain a CDI ignition to complete the installation process on your 20B engine. The kit does require a moderate level of fabrication ability, including welding skills. While we do provide comprehensive step-by-step instructions for the installation process, Racing Beat does offer the modification process, including fully bench-testing the completed assembly for a very reasonable charge.
