I have never seen a cutaway of the 4 port Renesis from the auto cars. Has anyone else seen any pictures? From the Mazdatrix website, each engine has a different eccentric shaft and a different intermediate housing. I'd love to know the differences between them and which ones may be better to use if one were built from misc. pieces. This isn't a 4 port vs 6 port debate. I am well aware of advantages of both setups. I am mostly just interested in the fine port details and internal pictures of the other engine. If anyone knows where some pictures are, please post them or a link. Thanks.

I would also like to see the cut away of the 4 port motor. Since it doesn't have the extra intake (variable) ports in the front and rear housings, would they be the ones that are different and the center housing the same? Maybe a different port style on the center. And why would there be a need for a different eccentric shafts. Counter weights for shure, but why the shaft? It has to be the motor for any retro fit applications.

That's what I wnat to know also. I would have thought that only the outer housings would be different and that is it. Apparently there is something different about the intermediate housing also. Why the different eccentric shaft I don't know. Obviously the outer housings are different. Is there a difference of weight in the engine? The rotors have the same part number.

Could Anyone take pictures on their Throttle Body on their rx8? So I can see what it looks like?
