Thanks for the history, Bob.
When I got interested in the rotary, the 12A was
out of production and only the 13B was being produced - my assumption was the
13B was the newer replacement for the 12A. I did not realize they were
co-produced for such a long period.

The 12A came out after the 10A in 1970 in the RX2. It was built
all the way through 1985. the 13B started in 1974 in the RX4, RX2, and rotary
Truck (which I happen to still have a Rotary Truck) and the Cosmo in 1976.
then 13B's stopped production in 1978 and switched to the 12A in the RX7. the
12A had been in the RX3 from 1972 through 1978. Of all the engines the 10A was
the smoothest running of the lot. It was like electric
power.

So True, Bob. One reason while I may
be panting in anticipation (I will not be holding my breath
{:>)). Interesting, I had always thought the 12A had long preceded
the 13B so far as used in Mazda vehicles.

Dont count on that. In 1979 the RX7 came out with the 12A.
Mazda told us (Mazda dealers) at that time we would never see a 13B again.
Then in 84 we see the 13B again and in 86 the 12A was gone. I know for a
fact, as a Mazda dealer, that Mazda or any other manufacturer never really
knows where the market will take them.

Ed, Cool
video. Love that sound! Too bad the 3-rotor will likely never be
produced in mass again. Good thing it will most likely outlast my
flying career. Mark (not Mike)

Ah, Mike. You think perhaps you joke
about the 24B. Take a look at the video of this Mazda Concept car
With perhaps a 24B in it!!! If the 2 rotor 1600cc is suppose to put
out around 250HP the 3 rotor 1600 should blow everything with pistons out
of the air (figurative speaking of course)

Yes, compared to the car installation, even our
busiest aircraft installation looks anemic.
Well, rather than
replace my older 91 13B with a Renesis, I may just wait for the
16B (but, I won't hold my breath {:>))

Hi
Ed,
Your off list help on the number of studs on the RX-7
throttle body paid
off. I never could see the fourth nut,
but I stuck a socket and
extension on the fourth corner and it
locked on to something. After
turning it a while, the
throttle body came right off.
I always wondered why people
would let the oil injector feed lines get
brittle and crack
without checking them once in a while. Now I know.
Who the
hell could ever find them without a shop manual. There
are
more hoses, wires, and devices attached to that engine and I
don't even
want to know what they are for.
The 1600 cc
engine is beautiful, thanks for the pictures. If they
put
it in a car, they will add so much junk that you won't ever
see the
engine.
I like old cars with a few modern
improvements, like electronic
ignition and EFI. This week I
started my '74 Suburban for the first
time in a year. It
has electronic ignition, manual choke, and an
electric fuel pump.
After charging the battery overnight, it started
right up.
After 60 miles on the highway it was running as good
as
ever. (That only cost me about 25 bucks for gas which is
why it
hadn't been started for a year.)

Things
been a bit quite of recently. How about a view of the 1600
cc rotary under development by Mazda. Those aluminum side
housing sure look nice. Rotor is thinner but larger in
diameter with a larger throw on the eccentric shaft for more
torque at all rpm. Saving my pennies.
