When using a Datsun Electronic Ignition distributor, you can use the stock 1200 coil as long as you leave the ballast resistor in place. But a high-energy Datsun coil has vastly better performance.

Overview
Stock points coil is 1.3 ohms + 1.5 ohm resistor = 3.2 ohm, so it will draw 3.75 amps at 12 volts (I=V/R). This low amperage is to prevent the contact points from burning out. Except when starting, it sees a lower voltage because of the Ballast Resistor.
Points coil: 3.75 amps Nissan IE coil: 12 amps (e.g. N12 Pulsar)
For best performance, use the Pulsar coil or other Datsun-Nissan coil from a high energy system. Or a compatible aftermarket coil. It draws 12.9 amps @ 0.93 ohms. Any 1980s era Datsun-Nissan EI coil should work just fine. With this type of coil, bypass the stock resistor. Remove it or simply jump a wire (short) across both terminals.
The coil from a Series 2 Bluebird (Datsun 910) or R31 Pintara with electronic dizzy may be used with Datsun/Nissan electronic ignition.
NOTE: Bosch GT40R or GT40RT can be used as a direct replacement for the stock 1200 coil, but is less powerful than the stocker 1.3 ohm coil.

Bosch HEC715 (made in China) is the aftermarket coil for EI systems, and draws more current (0.41 ohms). Consider using an ignition relay as this will draw a peak 29 amps (I=V/R) -- although considerably less in usage.
