Anyway, the gentleman involved seems to be doing a heck of a job on this, doing it all himself. No buying parts from Atkins for him... The website has not been updated in about a year, so I don't know the current status.

Looking at the Atkins website, they are now offering many of the unique parts for a single rotor 13B engine from stock.
Atkins Rotary - Rx7 | Rx8 | Mazda | Rotary | Engine | Parts

Their single rotor engine turnkey package is $8500, of course without a reduction drive. Weight is 220lb even with all of the cast iron parts and it makes about 96hp. It would seem that with more aluminum and lighter weight direct drive alternator it could be made lighter still.
