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:
