and no, the carbon buildup is NOT due to any manufacturing process as you stated. It's a result of owners *not* working out the engine like it needs to (ie driving the car below 4000 rpm for *years* and never letting the engine fully extend its legs)

 

ok, that is what i needed to know. I know that it is a higher reving engine and it needs to be run in its power band and at operating speed, i was just curious if anyone had experienced something excessive like that.

 

clear something up for me. Naturally aspriated meaning not forced like turbo right?

 

Right, but there are turbos on the market for it now, if your worried about power.

 

Or 2-3 times a day!

 

no not about that at all. Do you know where i could get a good look at what the intake is like, I would like to see what it looks like and how the air flow/ fule mixture moves into the engine chamber.

 

hmm, very good question. IIRC, there is an Official Mazda RX-8 technical highlight DVD floating around, which basically discusses tons of major engineering feats that are featured on the RX-8. I believe some people on this forum have a copy of it, maybe post another thread asking if someone can make a copy of the technical DVD for you?? :o

but even before that, I think no techno-chatter can replace actually driving the car... so maybe wait until after the test-drive to ask more questions??

 

I certainly will be asking more questions after I drive one. Thanks for the info.

 

Make sure you read a couple of threads. The Little Things thread (stickied at the top of this forum) is great and will tell you all the good things about the car. The Little (Disappointing) Things thread https://www.rx8club.com/rx-8-discussion-3/little-dissapointing-things-15980/ is even more useful since it points out the problems folks have with the car. That's the thread that cemented it for me - way fewer negatives than positives.
