I saw a video of Ron Gowan's rotary powered LongEZ. It showed him
inserting a distributor from a 1985 engine into his 1989 13b. It looks
like it has dual igniters, and dual vacuum cannisters. He
hooked the vacuum line to what appeared to be a connection near the oil
filler tube.  Am I correct in assuming that with the older distributor
ignition and vacuum advance that one would use the
stock Mazda coils?  Anyone familiar with the distributor style ignition
care to comment on it's reliability and or shortcomings?  Thanks in
advance for all replies.  Paul Conner

You really want to go back to points? ROFL

The 1985 did not have points. Just kidding.

The 1980's igniters were unreliable and $300 each if you can still find
them.

But why stop there? Go back further and  get an early 1970's RX4 ignition
and use points.

Better yet if you are serious about a non electronic engine I would
get a magneto from MSD.

Paul Conner and Mark Precious go to www.msdignition.com

They have lots of neat stuff. High flow injectors (peak & hold or
saturated),
high flow high pressure pumps for EFI systems, standalone fuel delivery
top
mounts for AN plumbing of injectors as well as all sorts of magnetos.

MSD ignition is pretty much standard for supercharged nitro burning cars.
Although called "magnetos", they are truly electronic.
The ones used in top fuel cars are 44amps, two are used, (dual plugs),
and by the time the car runs 1/4 mile, there are no electrodes left on the
plug.

Well one could argue an aircraft magneto is also electronic.
I think the criteria for a magneto is if the current generator is self contained or 
if it uses an external generator or alternator. They do have the Pro Mag 12LT series which
is not quite so heavy duty as the Pro Mag AA fuel  dragster type. Mainly for sprint cars.
The so called points box number PN 8106 is "for longer endurance and marine racing".
