Lets talk RENESIS
Look at the renesis pics in these pics.

Notice that the water oring grooves have been moved back into the peripheral housings. This makes lapping of the side housings easier. Also note the race clearanced rotors and the one piece apex seals. The tranny looks like it has a similar bolt pattern as the 13B, will this be "swappable"? Anything else you guys see?

I could be wrong but if there is another reason I am failing to figure it out.

Rotors still spinning
iTrader: (1)
There is a seal between the oil control rings and the side seals. This seal helps to insulate the oil rings from the exhaust heat as the rotor passes over the new exhaust ports.
The rotor edges are 45 degrees to help aid airflow as the edge of the rotors passes over the ports.
The apex seals still look to be 2 piece to me. They could just be glued together for visual purposes. I glue mine together when assembling my engines.
The intake and exhaust port edges are shaped very interestingly. I wonder why they aren't smoother?
The '6-port' intake runners in the housings are very differently sized. There are still rotating sleeves in the system but they are no longer actuated by airflow restricting rods. They somehow turn from above.
Those exhaust sleeves look like they can be opened up quite a bit for better flow.

One thing that I am wondering about the RENESIS is the fact that mazda said that turbocharging the RENESIS would result in the exhuast temps being Too COLD for the cats to work properly. . . Hummm well sounds odd. Is this because of the side exhuast ports? And I thought I was just starting to get rotarys...Oh well.

I think it's part of a marketing gimmick to use as an excuse not to turbocharge it. They know all RX-7 owners love turbos. To some people, rotary MEANS turbo.
It can be done. It will be done. Some companies are already making turbo kits for the RX-8.
ps - 3 rotor Renesis instead of turbo ... it's easy to add a turbo but not easy to add the 3rd rotor.

I think the emmissions on cold start is the problem. The renesis, I believe should have enough exhaust heat to propel the turbo and heat the cats under normal operating temps. The problem is getting the cats up to proper operating temps. Placing the cat ahead of the turbo would probably solve this problem but then you are decreasing the efficiency of the turbo system.

Rollin' coal and 53mpg!

With or without giggle gas?
