Lonnie- That photo was a nice inspiration. I'm definitely going to add a few little corner braces like yours.

Got all my header bits and have been making headway. Might have the exhaust done this weekend!

Some people never have anything except ideas. Go do it.
Emissions & fuel economy haven't exactly been areas of strength for past rotary power plants, but absolutely no one with a soul has ever cared.

Love what you are doing!
I'm also wanting to "save" the drivetrain of an RX8, and build it into my Datsun, Where did you find spec's about the mounting points?

Would like to do some CAD before I go further with my project as it is going to be a DD, and needs to go through engineering approval.

So cool project you got here, and great set of skills you got there too ;)

Exhaust is done! It doesn't look like it but there are probably 15-20 hours of TIG welding in this thing.

I also got my driveshaft done. I bought a driveshaft for an automatic RX-8, manuals have carbon fiber driveshafts, and had it cut and rewelded. Ended up taking 24" out of it for a finished length of 22".

Just seeing this now. Here's the mazda body shop manual for the RX-8. It has very good X & Y dimensions. The problem is their Z dimensions are to the end of the mounting bolts. Seems an odd place to pick. So it doesn't tell you the actual spot that the subframes mount to. I ended up measuring my car before I tore it apart for the Z dimension. I could grab them off my CAD model if you want too.

Great build so far, with my recent change to use all RX8 donor parts I will be referencing your build a bit, keep it up. :cheers:

Build is a plus 4" width, 13B Renesis. Wish me luck.
