So anyone out there own something other then a 7?
I was reading over the RX-7 Sports Car Color History book and wondered how many of you own a Repu, RX-3, RX-4, RX-5 and what not?
Kinda interesting, Mazda was going to be all rotary there for a bit.

I had a R-100 in highschool and a RX-2 shortly after. I wish I still had them. The R-100 had a bridgeported 13B in it and ran a 13 sec 1/4 mile. I could never keep mufflers on it.
The RX-2 was all stock with a 12A and twin distributors. It seemed pretty quick for a little car. It had the dreaded Rotary backfire problem (something rotary cars with thermal reactors have).
I think what killed the rotary was 2 fold, emissions and mileage. Also the Rotary engine is not for everyone.
Now that the rotary has direct injection and ignition I would if Mazda has played with alternate firing of the motor. At freeway speeds you don't need all that power, so don't supply fuel into every rotor. That would increase the Highway mileage for the Rotary.
Kinda, like what Chevy has done on the Covette with their skip shifting.
The REPU was a great idea. It gave V-6 power to a pickup that could be used to actually haul things (besides hauling ***). I knew a guy that towed a 18 foot ski boat with his. Something no other mini-truck could do.
I would love to see Mazda put the Rotary back in other vehciles. But the days of actually picking your options on a car are long gone.
In the early days of Mazda you could get vehicles with piston power or rotary.
Mazda 1200 = R100
Mazda 616 = RX2
Mazda 808 = RX3
Mazda 929 = RX4
Mazda RX5 (Cosmo)
(Ford Courier) = Mazda REPU

I've got a friend has had an R-100, Rx-3, Rx-4, Rx-7, Cosmo and a Ropu. Got another one who has put one in a Nissan Hardbody and another one with a Lotus Europa and Lotus Super 7, both with rotories. The Super 7 has a 13BT.

I was looking on an Aussie rotary site and they had some 3 rotor 13B's plus a few other odds and ends that we didn't get here in the states it seems.
Anyone know anything about em?
