canzoomer's mod will fix this. i don't usually make absolute statements like this, but i am sure that these specific problems, dealing specifically with the engine, are extremely solveable and caused by conditions extraneous to the design, manufacture, or operation fo this motor.
I hope these problems are solvable. However, the original claim of 250 HP sounds dubious as even the pre-production ECU untampered models still only got mid - upper 14s in the 1/4 mile. The RX8 at ~ 3,000 lbs. should have been closer to the S2000's 1/4 mile times (high 13s to low 14s) as the power-weight ratios should have been closer.

Still, Mazda cannot simply use Canzoomer's ECU reflash as it will burn out the Cat much quicker than EPU regulations allow. ECU reflashes are also available (or can be developed) for many other cars, so the RX8 will still be at a relative power disadvantage if both cars have reflashes.

i'm not saying it's perfect, and i recognize how disappointingly far from perfect it is, but there's no doubt in my mind that this motor isn't unbelievably brilliant.
I hope the potential is there as this engine would be a dream if this is true. Unfortunately, at least in production cars in recent years, the rotary has been dissapointing from a broad, holistic viewpoint.

You're right. I commented on the looks of those two cars stating that in my opinion they looked funny. Apparently you can't share your opinion here without others trying to make a big deal of it.

Looks matter. Anyone who's done any dating should realize that. The STi and Evo deliver race car performance at a reasonable price. They also look like what they are: Heavily modded econo-boxes.

There's nothing wrong with liking that look, but there's also nothing wrong with pointing it out.

The theme of many posts on here are that looks are more important to the point is that they would buy a car that looked great and drove like crap. That is why a "vain" reputation is in the cards if this continues.

Or you could be perpetuating that myth rev, by suggesting that those of us who have chosen the RX8 are not interested in performance simply because we didn't pick YOUR favorite to purchase..

No, because of their comments on other cars.

this is my opinion ^^

Ummm here in Austin I've been seeing more and more 8s on the street granted it was rare for most of 03 but I think thats not so much the case anymore. How many has mazda sold in 03? I know that Z sales in North America are about 50K for this year...for comparison

None of the cars I've seen mentioned in this thread drive like crap... in fact they range from well above average to jaw dropping in performance.

If the RX-8 drove like an '83 Plymouth Reliant, I'd be hearing ya, but that's not really the case. However, I'll concede that if you're intent on making your life an ongoing tribute to 2Fast2Furious then yes, you'd be silly to get an RX-8.

Different wants, different needs, different cars. No right or wrong answers.

*sigh* i don't give a flying crap if Mazda fixes it or not, 'cause people who're willing to sacrifice more (like noise, fuel economy, emissions equipment longevity of a car they're not going to keep for more than 5 or 6 years, etc) to get more will do just that: make the damned thing into exactly what they want.

the potential IS there, and i find it extremely hard to believe that you can say the 13BREW was a broad disappointment!!
i think the biggest problem with the rotary is that it's applied incorrectly: too many comprimises are made for people who aren't "getting" it, but i suppose that's the only way you're gonna sell very many of them. too bad, really too bad...

"True", other cars might have and ECU reflash, Canzoomers is a piggyback unit. but the whole point of his research and mod is that Mazda severly detuned the car due to emissions compliance, this also happened to hold back a lot of H.P. canzoomer is tricking the stock air/fuel ratios to allow for 25 to 50 W.H.P. depending on stage, I doubt your going to see that much improvement with another car with a reflash as that cars H.P. is pretty much at full potential anyway, unless you start adding some meat, such as internals, extrude honed, cams, pistons, headers, intake manifolds and forced induction.

Unfortunately, for me the car should offer that kind of performance out of the factory when a car is advertized as a sports car. (I don't mind the ability to add additional power with mods from there :D ) I have heard somewhere that the cats would only last around 20,000 miles or so with Canzoomer's mod (I could be wrong here) you are looking at replacing the cats every 20 monhts or going with a test pipe. In addition, you will be voiding many parts of the warranty (or at least having to fight like hell to get claims honored) when you start adding mods (yes, an ECU Reflash is not usually looked for by the dealer, but if Canzoomer becomes a rich man then maybe they will begin to test for reflashes to deny warranty claims)

You have been around here a long time too. A year to two years back people were talking about an S2000 killer, Slalom times around 70 MPH, etc. It just has not panned out yet. However, I agree with you that the biggest problem the RX8 has IS that its the wrong application for the rotary - the powerplant should be in a lighter car - say a Celica or smaller.

What are canzoomer's stages? Do they just involve the reflash or do they involve bolt-ons, etc? Also, what air-fuel ratio is he running?

In the US, based on the latest sales figures I have, Mazda has sold 10,267 RX-8s so far this year. Nissan has sold 34,604 350Zs so far this year. I don't have Canadian or Mexican figures handy. I do know that as a whole, VERY few cars are sold in Canada compared to the US.

You can see the sales reports at:

The RX-8 is a lot more luxerious car than the 350Z. If you want raw horsepower for bragging rights, I would get the 350Z. But if you want a car you can relax in while you drive fast, then the RX-8 is for you.

I was just thinking tonight on my way home from coffee how much I liked this car. It was cold out and my wife and I both had the heat warmers turned on. We were playing a nice ambient music CD which sounded great on the 300watt Bose radio, it really surrounded us with rich sound.

The dash looks great at night, and I love how there is a blue flash as the needle increases on the tachometer, its like the red needle is moving so fast it gives an effect of some sort. The inside of the RX-8 is just very plush and feels very expensive, like a BMW.

The 350Z has ugly yellow lights on the dash, a very weak stereo and no leather seats (except for the touring model). It just doesn't feel like you are getting your money's worth.

The RX-8 feels like a classic sports car with an emphasis on refinement, not raw power. It looks great, feels great and moves.

The 350Z is more hardcore in my opinion. It looks mean, the engine accelerates like a muscle car and eventually will just wear you out, especially on long drives.

And just for the record, the RX-8 was on Car and Drivers 10 best cars list, came in second to the Evo for Automobile Car of the Year, was Kiplingers car for 2004, beat out the 350z in the Edmunds article.

Test drive both cars and ask yourself if you reallt need that big engine feel the 350z gives you. Because if you don't race, there is no need for that engine, especially in the city. Wouldn't you rather be driving in a comortable car with the music system sounding good and the moonroof open? :D


Plug over.

And just for the record, the RX-8 was on Car and Drivers 10 best cars list...
The 350Z was on C&D 10 best cars list for 2003, won 2003 Motorweek's Drivers' Choice awards for best of the year and best performance car along w/a bunch of other awards.

But yes, I agree w/you Ioman on many of your points although I don't feel the Z's yellowish dash lights are ugly. Yeah, the Z is definitely more hardcore.

I just did an interesting comparo on some stretches of highway (some if it very bumpy) w/my Z, riding in my friend's RX-8 [not driving it, I can't drive stick worth beans.. please don't shoot me] and my 02 Maxima. I will say it was an interesting progression.

The RX-8 definitely has a smoother ride (not really bouncy, whereas my Z is) than my Enthusiast Z and the engine and exhaust sound NOTHING alike. What's funny is in the RX-8, I feel like I hear mostly exhaust noise and little engine noise. There was a bit less road noise in the 8 than the Z. Also, the noise from the rain splashing in the wheel wells was a lot quieter on the 8. The door sills aren't as high in the 8 so you don't feel like you're sitting as low as you are in the Z. As I mentioned before, the 8's interior is definitely of far better quality than the Z. In an underground parking garage, you can definitely hear a really nice throaty exhaust noise from the Z. The 8 sounds totally different and DOES sound turbine engine like.

The Max has a way smoother ride than either, has less engine and exhaust noise than either (even though it uses the same engine as my Z, it doesn't sound anything alike). You sit higher in the Max it has a non-sporty exhaust sound.

For me, if if the 8 had a bit more power, got rid of the rear doors (looks funny to me, or if it just looked like a Z), and there were no engine probs, I'd be more inclined to buy it. But yeah, I can see the appeal of the 8.

The Z, and even the G35C scream sports car. I've ridden in all three of the cars, and driven the 6MT G35C. They all have their good and bad points...the RX8's bad point being that it dosen't "go fast" but the engine is so responsive, I'd think you'd have to be a speed freak to care. The Z and G both have an extremely seductive exhaust note. It was actually designed to mimic the sound of a V12. The RX8 just screams rotary when you floor it. It sounds more like a rotary than my friend's old Turbo II.

IMO, the RX8 has better interior materials than the 350Z and G35C. The G has pretty stiff roll motions, probably due to the wide tires on it. The suspension reacts quickly to bumps. The Z is even more reactive to bumps as spring rate up front is twice as high as the G...in fact, some 350Z owners complain about "porpising"

Like Jeremy Clarkson's cohost said, the Z is a "big BUTCH car". It feels sporty, but in a very hefty sort of way. When you change the gears, it feels like you're shoving huge heavy industrial gears around, and when the torque pulls you into your seat, it's like a freight-train. In contrast, the RX8 dances lightly on it's feet, dosen't bruise your *** when you come off a driveway, and happens to be a nice place for all the passengers.

Big deal a FEW engines have blown. From what I read its a very small insignifigant number. I can point to threads on the S2000 board and the 350Z board that had engines replaced under 6000 miles.

when the 99 miata came out ALOT of engines were lost due to the #4 bearing issue those were all fixed.

I believe in the RX-8 and what mazda is doing. Good, bad or indifferent the rotary is what put mazda on the map. Its the one thing that sets the "RX" series apart from every other car. Its a very unique car, nothing looks like it, nothing drives like it.

What is it that makes a car special? Sure car and driver put the Rx-8 on the 10 Best list (notice 350Z is NOT there). Its got the best reviews I have seen since the Rx-7 in late 1992. Despite having low power it has managed to win its comparisions with the competition? Notice that every single review talks about how on paper its nothing special but when you drive it you realize what a sports car is supposed to be?

The only thing the 350Z has on the rx-8 is alot of low end torque. Big deal the 350Z can do low/mid 14's and is roughly 3/4 of a second faster than a Rx-8 with same skill driver. The 350Z isn't exactly fast either. You want power and speed neither car is that great, but as far as being fun to drive, handling, agility and character we know who the winner is.

If you state you position politely, as in: "I don't like the 8 because I don't like the HP/I don't think it has enough torque/I don't trust the engine because it's a first year run" and not "The 8 sucks *** and you are stupid cause you bought it" no one cares that you don't like it and say so. You're more than entitled to your own opinion. Look at Ike. He doesn't seem to like it, yet because he's NICE about it, he's pretty well respected.

As for your little jab, there- ever so clever of you to ignore the actual facts. The buy back didn't have to happen- Mazda was NICE to everyone. They were well within their rights to go "oops, we screwed up, sorry about that, here's the real hp." and leave it at that. How many other companys have done that and actually tried to make good on their mistake? Engine flooding hasn't happened the majority of us, and the same goes for the blown engines. We have heard a rumor that there have been as many as what, 70 total? Out of more than 10,000 cars now floating around? And we don't have any hard proof from Mazda or anyone else (no offense Canzoomer).

There are no more issues with this car than any other first year run. And there are no recalls. So what's your point?

Cool

Has anyone seen the info re the 350Z's front end problem? Seems that the front suspension has something out of wack that causes premature wear of the front tires. There hasn't been any recall, but as I understand, Nissan is replacing tires under warranty while they try to find a way to correct the alignment problem.
The point being, all cars have some problems, particularly new ones. I've owned upteen dz cars and have yet to find the perfect one. Up to this point (4,500mi.) however, I haven't experienced any problems with my RX-8. Doesn't mean I won't, but none yet. My Miata has been trouble-free for 18k miles (recalled for the foglight bracket), including 6-7 autocross events. Oh, the OEM tires sucked and were replaced at 11.5k miles.
Comparisons aren't worth a whole lot in my book. A "good" car is one that you like to drive, be seen in, and isn't in the shop all the time. JMHO.

I'd be curious to see those threads on 350Z forums. I can't think of any on lightly or unmodded Zs that needed new engines.

As for 10Best, the Z was on there for 2003. See http://www.caranddriver.com/article....ticle_id=2423. As for 1/4 mile... there's a lot of variation, but the fastest stock time I've seen so far is 13.73. It seems to be in the very high 13s or low 14s unless the driver was lousy or they were at high altitudes and/or high temps.
