On another topic, let me make one more observation. While the engines are very RPM tolerant and it is a good idea to redline them periodically to blow out the carbon, it is NOT a good idea to drive a high RPMs continuously if you are at all concerned with longevity. The most obvious issue is wear. An engine averaging 3K RPM will last waaaaaaaaay longer than one averaging 5K or even 4K, ceteris paribus. Friction, friction, friction. Apex seals wear, rotor housings wear, main bearings wear and rotor bearings wear. Also, the engines put out a great deal of heat and the thermal cycling is problematic for the soft seals and hard seal springs, plus the water pump is not designed to operate for long periods of time at high RPM. Also, an engine using an electric fan will typically have more severe thermal fluxuations than one using the clutch fan, so keep that in mind as well. By all means, redline once or twice a day, but if you baby it the rest of the time, it will last longer. "Driving it like you stole it" is not a receipe for longevity. Fun, yes. I'm not saying don't have fun but don't delude yourselves into thinking the engines love punishment just because they can handle high transient RPMs. There are many places I like to visit but don't want to live: 7K+ RPM is one of them.

If that happens, when you want them to spray gas, they can't. If they can't, you get an unusually lean air/fuel ratio and risk detonation. In rotaries, detonation is bad news. That's why they always say redline it every so often, it "cleans out the pipes" so to speak....
The main benefit of redlineing is to clear the carbon out of the combustion chamber, which I have heard has been a issue with the 8s. I attribute that to the older demographic of buyers that the car seems to attract. My Doctor's ex had one and had nothing but trouble with it. Of course she only drove it short trips to and from work and never stretched it's legs.

I think thats also a reason why these 8's are breaking (mentioned in the last post). There are 8's being bought by people who have never owned a rotary before. They like the look of the car....its like a $30k sports car...they buy it without even knowing there is a rotary inside.
We all love our first gens....we love nursing them....making them go faster, helping others get their's back on the road. Man, just have a look at that 'you know when you're a first gen owner thread' That is a classic. Those posts apply to all of us.
I'm sure you can't say the same about 8 owners just yet.
Also, I bet if every 8 owner did have a first gen at some point, they probably would not be having the problems they are having now. And would also understand the car a little better. (carbon lock, premix, etc, etc)

The secondaries come online around 36-3800 rpm on the earlier engines, I will venture a guess that the new one does too, ergo, normal driving should open them often enough to keep the working. I have seen secondaries with problems because they were not used enough though.

I'm sure all of us first gen owners aspire to having an 8 one day....but gee whiz...
our first gen's don't have problems like these guys are having...and there are like 20 years difference between the cars !

You have to read the fist sticky "satisfaction with your rx8" There are hundreds of satisfied owners. I'v had my 2004 rx8 for 2.5 years and it is a very dependable dailey driver that doubles as a purebred sports car.
Most of the bugs are worked out in 2005 and 2004s were corrected with TBS and recalls. It's the car to own and gets constant rave reviews from all professional mags and drivers. All first year cars have thier problems. Mazda stands by it's product. Some may be lemons but very few compared to the vast number on the road. It's a great car. Your always going to read of problems on these forums. That's where people go to gripe when they've had trouble with thier new vehicle.

I get just as many looks, comments, and questions about my first gen as I do my RX-8. They are both dear to my heart. I'm happily married and I have two girlfriends which are 20 years apart in age......

I want a blue '05 model to replace/supplement my 1st gen when I graduate college after next year. I figure I won't even notice the crappy gas mileage, since I've only ever driven gas hogs lol.

I love the Rx8- They have great handling. The Rx8 has more room then the 1st gen deffintly, those rear seats make it towhere you can scoot the seat back alot.
I think its a ball to ride in. Its been to flordia 7 times, from louisiana.
I weight 220, and my shoulders dont hit the door in it :P
