Mazda RX7 Donor Car ??
I am a rotary fan.
I am actually building a Beach Buggy with an RX7 engine.
Though I am really tempted to finally put a Porsche or Subaru engine on the buggy and the RX7 engine on the Locost. It is a 13B N/A. What do you
think?
Has any one used an RX7 FC3S or FD3S as a donor car in the past?
I dont see a reason why not use its gearbox, diff etc.
Regards
Alex

Sounds cool to me They are pretty compact power units. Where can you get these cheap?

You can get a Second generation (FC3S) RX7 on ebay for around £600-800 N/A (160bhp).
A turbo one would go for £1500+ (200bhp)
Forget the 3rd generation i think is much more complicated and even more unreliable.
My engine was not removed by a Mazda.. It was removed from an old scholl skoda:

from reading the article in PPC with the rotary engined chevette, because the crank's in the middle of the engine, not at the bottom, the engine
has to sit a lot lower or the gearbox has to sit high. as for the real displacement from a normal setup i don't know how great it actually is,
but i doubt it'll go in a normal transmission tunnel.
both would cause you problems in a 7, but i guess either could be overcome if you really wanted to.

No real problems in a 7...
I'm fitting an RX8 engine and 6-speed box into my Caterham S3 chassis (tiniest of the tiny), and the mock-up shows that it all will squeeze in
their.
Should be even easier on a book-style chassis which is larger than a Caterham.

The excentric shaft is more or less in the middle, but don't forget the complete engine is a lot lower. Thus making the gearbox not really
higher than a "normal" one.
With a "normal" piston engine the flywheel is dictating the shape/size of the bellhousing, and with a rotary it's not really any
different in that area. It's more that there's a lot less ABOVE the flywheel on a rotary, esp. if you go for carbs, or EFI using carb
style throttle bodies.

Hi,
Go for it
I have fitted a turbo 13b in my stylus which is a similar chasis to the seven.
The egi box will definately fit, its a little bit smaller than the turbo II box i am using.
I have an RX8 6 speed which would be tight so i am not using it.
The 12a is even smaller still. All the gearboxes bolt to all the engines, including rx8.
The 13b REW (3rd Gen) is no more complicated as you would be getting rid of all the complicated bits and the blocks are virtually the same. Other than
the porting which can be almost matched.
My last turbo II made 460 Fly bhp on a mild port and a medium turbo.
Here is a link to my build

Rotaries are pretty commonly used in Seven-type cars in New Zealand.
