Mazda rotory swap? (Page 1/2)
Rickady88GT NOV 14, 02:05 PM
Just wondering if anyone has done or tried a rotory swap? Besides a bellhousing adapter, what would prevent this engine from going in?
I know the direction of crank rotation isn't an issue because both directions are available from different manufacturers.
The sound of these things is amazing

Exhaust manifold will interfere with the passenger axle in a transverse setup.

You could mate it to the Audi 01e transaxle (fwd version) in a longitudinal setup.

Of course you'd lose the trunk....

Thanks, I actually did see this thread after I posted this topic. I found it in a Google search.
This has my interest, because if the exhaust is the only issue, it seems like a cool swap.

I had the same problem swapping a rotory into my Samurai. I cut the outlet turned it to where it would not interfere with anything and re welded it. I am trying to attach a picture.

I see no advantage in a rotary engine swap. Those engines were not economical, burned excessive oil, prodiced high emissions and the wear was excessive The design is dead, repair parts are scarce so why would you want it in your Fiero?.

I hear you, but people do strange things for their own reasons I guess. For me, I like the sound and I am not worried about were because I wouldn't drive it enough to were it out. I am used to poor mileage. And it it different.

The rotary engine can be a lot of fun. It's small, revs high, sounds great, and is fantastic when turbo'd. 🙂 Not everything needs to be practical.

Several people have commented on how "amazing" a Wankel engine sounds. Different strokes for different folks I guess. I'm old enough to have heard in person on the street every model with a rotary engine that Mazda made... and I honestly thought they all sounded rather anemic, at least during normal around-town driving.

Maybe it's the same people who enjoy the whine of a turbine who like the sound a rotary engine makes... when it's wound up to 10k RPM?

I can remember when the Mazda Cosmo was introduced back in '68. It was unique.

I actually kinda like that car. At least that picture of it. It looks like a Ford Tbird.
