I want to put a newer 81 engine into my older 80 rx7 wich has the old style dizzy. I plan to run the engine without the emmisions crap. Will the old style dizzy work fine with the newer engine? Are the old dizzy's as good as the newer ones? I have another wiring harness and dash etc for a 81. Shud I change the wiring harness over and the dash? Will the back tailight plugs plug into the newer harness? If anyone out there can answer a few of these questions it would be greatly appreciated. Thanks

 

The newer engine will have an electronic ignition rather than the points setup... this does not have the dwell change with twear... In my oninion better.

The rest I don't have time to answer right now...

Free bump

 

I gess I will try to use the old points setup dizzy on the newer motor. If there are any problems I will swap the entire wiring harness dash etc. thanks for the info toxic

 

why would you want the points setup?

 

I doubt there is much electronics that need to be swapped.... unless of course you need all the emissions crap.

 

The '80 dizzy is fine to keep, but if your car has a '79 points dizzy, I'd recommend an '81-'85 dizzy.

 

ive got a extra or two dizzy's

 

The upgrade is easy and recommended.

If you've never done one before, the engine swap should be easy as well; aligning the clutch splines is the hardest part. A Haynes manual will provide the steps just take your time. Good luck.

 

Thanks guys I think I got it figured out, Im gona try stick with the old wiring harness and distributor for now. If there is any problems I will just switch everything wiring harness, dash, headlights, distirbutor etc... I have tons of rx7 parts so theres np. Thanks for the info guys.
