GT2 Posted July 30, 2021 Report Share Posted July 30, 2021 Hi guys and gals, I'm converting to a " manual" distributor. At the end of the video I'm asking some questions about how to wire it. So if you want to skip to near the end please do so and comment. Thanks, Tim Quote Link to comment
GT2 Posted August 4, 2021 Author Report Share Posted August 4, 2021 Does anyone know if the Z22, 720 engine uses internally resisted coils or not? Quote Link to comment
datzenmike Posted August 4, 2021 Report Share Posted August 4, 2021 External ballast ignitions stopped after '77. This is when the EI (electronic ignition) was introduced. Without points holding everything back, coils could be made with a resistance of just under one ohm which allowed a higher current through them, making a denser magnetic field producing a hotter spark. So NO, all from '78 on did not have an added internal resistance in the coil or anywhere else. To be clear I know of no Datsun or Nissan that ever came with an internally ballasted coil. The Z22 coils would have a primary resistance of around 1 ohm. Quote Link to comment
