you can run the old distributer, there is no reason you cant. just drop it in and make sure your timing is right. but changing the distributer would be a good idea because the 79 to 80 rx7's used a point style distributer. the point style dizzys are really not that great. if you are not to worried about doing alittle more work Id upgrade to the 81 to 85 dizzy. thay run alot better and give you a lot better and stronger spark

should be able to use the '80 dizzy they are not point style
igniters are mounted on the shock tower near the coils instead of being mounted on the dizzy ala '81-85 style

k so im using the 81 distributer and trying to figure out how the wires go, the coils have the two black and white wires going to the ignition then the two yellow and green wires go to the distributer then to something... i think they go to the tach, is it possible to splice tho's???

You know you're a RX-7 owner if =)
...a girl asks if you are single and you bring her over to the front of the car and pop your hood.
...You are still trying to understand why the other cars slow down for the tight corners
...your neighbor across the street fires up his chainsaw and you run to the window because you think your car is being stolen. lol
