One thick aluminum disc mounted on the front pulley. One iron reluctor
mounted in the edge of the disc. A length of 1/4" bolt works fine. Make the
disc the same diameter as a Mr. Gasket degree wheel. Mount the degree wheel
on the front of the disc. Makes setting timing dead easy.
Two pickups mounted 180 degrees apart to be tripped by the reluctor.
One pickup fires an MSD or similar so as to light off a double ended
coil (MSD has these) or two Blaster coils in parallel if you need the extra
weight. To fire leading and trailing plugs in housing one together.
The second pickup fires housing two. Keep plug wires as short as is
possible.
Adjust reluctor disc so as to fire plugs at 20 to 26 degrees BTDC. Good
from idle to 10,000 RPM and 250 HP. Used on racing engines for years. Use
NGK 11.5 heat range plugs gapped at .010".
Non turbo engines only. Ignition timing is so accurate that the engine
appears to be not running when a timing light is used.

I'm wanting to use a carbureted Renesis for my build. Eliminating
both the fuel injection system and the emissions system, I have no need to
keep the stock ECM. What would be the easiest ignition system to use? I'm
thinking a hall effect crank angle sensor feeding an MSD 6A/Crane Fireball
Hi6/similar low cost unit and three coils: one for each trailing plug and
one for both leading plugs (leading plugs fire a waste spark similar to
the 2nd and 3rd generation RX7s).
Would this be a matter of simply installing a universal aftermarket
crank trigger kit and having the sensors trigger an ignition module? Would
I need one or three ignition modules to achieve this?
Many thanks,
Chad.
