I would recommend the M&W Pro14R. Average sale price is in the upper $900 range but its worth it. The coils will run you about another $400.

By the way, I'm running this ignition (M&W Pro14R) with a Motec M84.

M&W Pro14R information:

The Rotary CDI is a special four channel unit that allows 4 outputs to be run at full power with or without split. This unit is specifically designed for the Mazda Rotary engine. It features four trigger inputs and four coil outputs which may be configured in a number of ways. Please contact us for specific application information.

HKS Twin Power. We run 500 to the wheels with it without a single ignition issue. Don't waste your time with old, bulky MSD boxes.

+1, I personally am running an M&W CDI right now but I noticed no difference going from the twin power setup even with high boost and injecting plenty of water. Maybe I hadn't pushed the twin power far enough but I figure its more then enough for most peoples needs.

If your set on getting aftermarket coils though, AEM has some nice ones that output almost as much spark energy as the M&W. They're about $70 each with builtin ignitor, less without.

What ECU are you using? What are your power goals? What fuel will you use?

Buy the M&Ws! You won't regret it. And at Ernie T's price, you can't beat it. Pro Drag 4 or 4R.
