I am pretty sure you can use a MSD 6AL and trigger it on the green and purple wire into the MSD from the stock dizzy.

Get yourself a MSD and hook the big black wire to ground. Hook the big red wire to 12V from the battery/starter terminal. Hook the little red wire to a switched 12V. This little wire is "Ignition On". You will not use the white and orange wires.

Use the pigtailed connector out of one end of the MSD to run to your dizzy. This is your trigger for the MSD. This will be connected to the short pigtail two wires out of your stock dizzy. If you get the polarity of the trigger wrong it won't fire. Just reverse them.

Now, I am taking a leap of faith in that I think your dizzy is very similar to the one in my 260Z. I think it is as I've seen a 280z dizzy not too long ago.

Use a two pole kill switch, the one with alternator kill. On your kill switch run the 12V positive with some 2 gauge (or whatever you like) wire to one side of the kill switch. On the other side run some 2 gauge to the starter lug that will then be used for power take off for everything else on your car.

The alternator wiring is simple as well. Just hook one side up to the 12V output of the alternator, then put the other side to a load like a 2-3 ohm resistor so that the alternator discharges into that load when the switch is activated. The alternator will also be connected to the starter lug too.

There are other ways to do the alternator as well. Some are not so friendly to the alternator, but if you figure it gets used once or twice a year in tech checks you will probably be okay.

Before you do your wiring make sure the switch is in the proper position etc.

Hold on, do a search, follow this diagram for the kill switch:
