Here's the link Enrique was referring to, the ignition upgrade is half way down the page.

the one to get is from a '79 or '80 280zx be sure to get the small mounting piece at the bottom of the dist. that it mounts to. The zx coil is larger so get that mount also , there is a small black box on the side of the dist. and they are marked 12 80 . there are others but they are marked 12 94 and need a computer to make them work . I bought mine at a bone yard complete with ignition wires and coil . $75. and have been running it for over 2yrs with only good results. remember 12 80

Thanks for the help, I will look into it.

When you turn the key it sends 12v to the coil for a hot spark to start the car.When the key is released (run position)The 12v travels thru a different wire that passes thru the ballast resistor.This resistor is a strip of stainless steel in most cars.It doesn't conduct as well as copper wire and therefore causes a voltage drop.This drop is to extend the coil life by not allowing it to run at maximum output all the time.For test purposes you can wire across it therefore taking it out of the circuit.Some post I have read say "car won't start,replaced ballast resistor"Now we all know that is an incorrect diagnosis. Have fun!! Daniel

Thanks for the explaination daniel. I got her running finally. Just a wire broke off.

Thanks again
