I am a BIG fan of Jaycar and use them alot for bits and pieces so i would expect their ignition kit to work well.
I am still worried about your fuel delivery though...
In my personal opinion you should still go for a cheapish aftermarket fuel control ecu. Most of these have a built in MAP sensor so you can get rid of the AFM completely and upgrade your injectors with something bigger and cheap. This way you can borrow a EGO sensor or let a joint with a dyno tune it and end up with a good, fast, reliable engine. With the added bonus that if you decide to change anything (engine, SC etc) you can remap it to suit. Also things like idle control and cold start assist will work better. The other reason I am doubtful is that I hav never seen it done before, usually a good sign that it is too hard/expensive or just does not work. Although i spend most of my time around rotary's so maybe someone else has seen it work...
I just don't want to see you spend lots of money and time working on something that ends up a dud. The way i see it, any extra money now will be worth it in the long run.
