The rotors are also lighter and have a higher compression I beleive 10:1 ratio. When using them they are slant cut and you have to use the front renises rotor in the rear of the 13B engine and the rear renises rotor in the front of the 13B engine. Mazdatrix sent me info on this a while back.

NO significant features on both interior and exterior... so far the engine is weak and I would give 10 out of 10 that Apex Seals and fuel injectors are improved.
Hmmm RX8 Shift ****... I should try that on my S5.

i won't even comment because i don't want to make you cry, all i have to say is post the right info next time before posting this BS.
i'm no one to bow to an 8 but keep in mind the **** doesn't have a turbo on it...

a drawback i just heard from a friend is the apex seals. he says that even though the rotors are 2mm, the design of the grooves are different due to the change from prephiral exhaust to side ports. i'll try to look into it more just warning you guys for now

why would that be a drawback? imo it would be a strength since the seals would not have to worry about passing over the PP exhaust port. peripherals cause apex seal chatter causing added wear to the seals, springs and rotors.
if you have ever seen chattered rotor housings you will know what i mean, those motors either had weak apex seal springs or saw high RPMs too often. though the exhaust goes straight out there is backpressure in the port which compresses the seal to the rotor while passing over the port, you can see this by the carbon faced lines at the port opening and closing edges, at higher RPMs the seals 'bounce' on the face of the housing until they settle down.

No es bueno.

personally i dont like the way they ride, although i cant say much because i havnt driven one. main interior piece i didnt like was the center console, or really the exterior or suicide doors, but as for the engine, i love the NA 238hp and the 9000rpm redline.

Man dont you guys watch best motoring or hot version. They praised the Rx8 for it's handling abilities. Yes they agreed it's not a fun car to drive when competing against turbos, but when going out for fun on a weekend they're great. These chassis are so good you see people putting FD motors in them. So, they can get the turbo power and Rx8 handling.

I'd really like to know what is interchangeable, and if it offers an upgrade in any way. Doing a rebuild soon, and I wouldn't mind having a few options to improve on the stock engine.
Could we please keep this from becoming an rx-8 sucks thread, really who gives a crap, we are FC drivers, the 8 is a totally different car.

i had an 8 for just about a year before getting rid of it, it was fun and handled tightly and the suspension was pretty stiff stock. there a blast to take out on the back roads here by napa. my opinion is an 8 is way faster than an fc probably even a t2, but the fc definately has better turn in, i really won't be able to tell the difference till i upgrade my tires and rims though cause an 8 comes stock on 18x8 or 18x9 w rated tires while i have some crappy stock tires on my fc. currently it's really easy to skitter around corners which i never even got the slightest chirping cornering in the 8
back on topic, somewhere i saw a 7 with rx8 rotors in it i'll try and find the link but it'll take a while if i can even find it again

I've ridden in one and it runs on 87, and revs so smooth and sounds awesome. The power band is nice and wide. I heard they have like 4 auxiliary ports instead of 2 on the FC na. So you have 3 stages of port openess, to keep air velocity high at all rpms. Doing something like that on a FC would be awesome but obviously useless for turbos.

could you really use RX-8 rotors in a 13b? (the renisis is built off the same block, right?)
if you could, the 10.1 rotors would help, the turbo2 rotors are 8.2 stock, right? that would mean a 23% increase in power (237 hp)
lighter rotors would also mean that your redline becomes a little superfluous
that would be something to consider in a rebuild eh?

Nowhere near it. Basically nothing is interchangeable except the rotating assembly, and even then the rotors require machining to use standard apex seals.
I also recently tried the rx8 alternator on an FC. It looks basically identical to an FD alternator and is rated 100A just like the Fd alt. I put on an FD conversion pulley onto the rx8 alt and put it onto my FC. It refused to charge whatsoever for some reason...apparently the 2 wire plug must be set up different than the FC and s5 FC.
ON another note, I actually have 2 FC parts on my rx-8. I have s5 aero mirrors on and they are almost a bolt on, requiring only minor modification. I also put an FC oil cooler on since mine is an auto and only came with the one small oil cooler.
