D that looks like a 36 tooth chain sprocket.

Do those work like trigger wheels?

After more thought...

To keep the focus on Turbo EFI A12, it would be simpler to retain the standard distributor. There is no need to use crank trigger. You can still do programmable spark curves without it. Works with EI distributors too.

Is there anyway of fitting the sensor and trigger to the dizzy cap and rotor? Not sure if its preferred but it's a different thought :\

Seen e15t dizzy in a A15 it used multiple coils here in perth

You can use the standard 1200 distributor with multiple coils. MicroSquirt 2 can fire two GM V6, or one AUS LTD coil pack, or a Mitsu coil pack, etc.

If it's somewhat simple, and efficient.. I'm ready to see it.

I got my Hyundai 40MM TB, 2-500cc injectors, or 4-275cc's, 2 different superchargers to try, and my CNC on the ready.

Yes, sikyne will make it relatively simple.

Turbos are the most efficient. Blowers take HP to drive but turbos are basically free HP. Its why almost every automaker in 2015 is using turbos to meet fuel economy and emissions targets. From Ford's EcoBoost to Ferrari's "no more NA engines".

I got a turbo but the USA cars have zero room on the flow side of the engine.
