Electric turbo & ignition

Just thinking out of the box.
Hi Dave,
Yes, the shop vac is always possible. Actually, my leaf blower has a suction adapter, and may be used - LOL! Also, electric turbos were researched first (see videos on youtube). Generally, a high power electric motor replaces the exhaust turbine. Aside from the obvious problem marinizing electric motors on outboard engines, compressor output is limited. I'd given thought to adding one to the fore bank for starting only, but the weight, complexity, and cost ruled out the exercise for the prototype.
What I really need help with is an ignition system, preferably battery CD or HEI (for reasonable $$$). The least cost method is twin, conventional, belt driven, (petite) VW Type 1 distributors & two coils. The next method is an under the flywheel crank trigger battery CD system based on readily available marine parts (available but pricey). Finally, I'm considering building my own with four inductive sensors, coupled to four GM HEI ignition modules, firing four Siamese ignition coils.
Do any of you engine or ignition guru's have any experience with an inductive HEI?
