From what I'm understanding, Mazda USA have gave up before RX8 came out. Most of the RX's had hard time passing smog cause of the very high compression or something have to do with US regulation failure, I forgot what was the problem. It's been a while. Anyway, in Mazda Japan did had the concept of the as RX7 FE3S back in 2003 when RX7 FD3S discontinued. They started to developed sportcars either Rotary Miata or RX7. As I remembered, Mazda Japan, wanted to change and putting little bit new style to the taste. So they came up with call RX8 with rear suicide doors, and making the rotary advance for US regulation(Renesis). So, everything went well for Japan, then in US did some tested and failed few times. Mazda US want it this RX8 to be in US, so US regulation made the Rotary more officiation data on smog regulation.
Now, I spoked to one the guy from San Diego Motorsports(not sure what was the name of that place), he had 13BT rotary in his RX8 when the RX8 first came out. He stated that he couldn't find the way to make Rotary Renesis higher HP nor WHP. He ended up swapped the 13BT on it, just to show up the 7Stock event with it. I wish I can get in to FD but I had at least 4 RX7 FC3S, and that too much money in to it and time. Rotary is a badass but damn got to keep it up at all times. I can't imagine having FD3S, that would be more money and more babied to it.
Sorry about the typing or english, I'm bad at it! I wish I wasn't deaf.
