cool... the plot thickens- I will do some further research!

On the A15 EFI front... yeah- I realise the EFI part won't be particularly straight forward, but I have played with old BMWs pretty extensively before (I also own a 323i) and have converted that to EFI from mechanical injection, so I have some experience in wiring stuff up and making it work! :)

Probably use the old N13 Pulsar system as a starting point with a fabbed up manifold.
