i know i have to replace the CAS....but i need to know what is involved in doing this, where do i get a distributor from, ect.

 

Carb conversion?
You can't do this if you're planning to keep the stock ECU and fuel injectors...
Unless you're going stand-alone?
If you are going stand-alone, you're taking a step BACKWARDS, IMNSHO.

I'll answer your question.

Get a distributor from an early 13b or 12a (first gen rx-7, repu, etc..) each model has a slightly different advance curve, but nothing you would notice. You will need two coils, msd blaster2 coils are fairly cheap and a pretty good unit. For the wiring:

Switched 12v to both coil positives, and both ignitor positives. Leading ignitor neg to leading coil neg. Trailing ignitor neg to trailing coil neg. Tachometer pickup wire to either coil negative, but not both. Then wire up the spark plug wires and you are good to go...unless you are using the stock computer as stated earlier. For this conversion you will either need to convert to a carby or a fuel only standalone...or be pretty tricky with the stock ecu.
