I have an 80 distributor laying around and I am wondering if I can lock it and use it on my 85 set up? I already have eveyrthing to convert it to use it for the 80 set up because I had an 80 parts car and kept the ignition. So i have the wiring and the heat sink and all that? But do you guys think it could be worth it to use the 80 for the turbo set up and keep my 85 for stock just incase? OR just go get another 85 dizzy and lock it and use it instead. The final question in the turbo set up. Thanks And is there any link to show how to lock a dizzy? YEs I have looked.

 

The '80 and '85 distributors have the same mechanical and vacuum advance.

What would you need to modify?

 

To lock a dizzy you need to take it almost completely apart. Start at the top and just keep pulling things off until you see two weights with springs attached. Take off the springs and put the piece that goes on top of the weights back on. Turn that piece so the weights move all the way outward in those slots and then weld the weights in place. Now just put it back together.

 

Why not just remove the springs? That way you aren't fighting ignition advance when starting the car, and as soon as the engine fires the weights go to full advance.

edit: Or why bother even going to all that trouble and just go with a form of boost retard...

 

Well I want the least expensive, and thought that I could do it with a spare dizzy. If you didn't know the 80 is different externally than the 85. Thats the only reason I asked. I know how to do the locking part of it, just wasn't sure if I should use the 109 or 105 ignitors and stuff like that.

 

I know. Boy howdy do I know.
