Are you willing to change the trigger wheel? You could look at the Mega 
Jolt (ignition only). It requires a 36-1 wheel, like Ford uses here in 
the USA (might be the same down under).

If you're interested in alternatives in full injection/ignition 
controllers, the Micro Squirt & Mega Squirt systems can both be set up 
for a rotary. Micro Squirt will have batch fired injectors (like almost 
all aftermarket systems for aviation engines). Mega Squirt can be set up 
just about any way you can dream up.

The Micro Squirt controller with harness is about $400 US. The Mega 
Squirt controller is about $600 US.

The car guys love them. Here's a link to an RX-7 forum page on the Mega 
Squirt:
