There is nothing wrong with the Mazda engine. All of the earlier problems
have been dealt with effectively and you are likely to see more and more
installations as the word gets out that the Mazda DOESN'T use excessive fuel
or burn up properly designed exhaust systems. But it is loud and most
builders seem to eventually opt for a muffler of some kind. Pound for pound
here is no higher horse power output in a normally aspirated auto conversion
than that of the Mazda Wankel.

Hey Corky,

What was your beef with the 13B? I have to replace a car coming off
lease in the next few months and I'm seriously looking at older RX-7s
just to get a flavor for the power plant.

I like the idea of a no-seize failure mode and the idea of it being 2
co-axial engines in one. The higher fuel burn I can deal with,
especially since its mogas.

Regards

I thought I'd bring everyone up to date. It's true that I had
basically given up on using an auto conversion as I was having trouble
justifying the cost of the PSRU. I'd started with a Buick/Olds 215
cid aluminum block V-8 and then switched to the Mazda 13B. I disliked
all the problems associated with the 13B so I sold that too.
