RX-8 Discussion General discussion about the RX-8 that doesn't fit in one of the specialty forums.

Is the 8 really all that slow?

My main grip speed wise is that I don't think the 8 has enough passing power. It's 50-70 sucks and that's more important than 0-60. When I'm on a highway going up hill and I need to pass a truck the 8 is slower than a lot of "non-performance" cars.
I hear ya, but I don't feel the pain as much as you, but yeah, sometimes it's strange knowing that a V6 Camry can dish out some whoop *** at the drag strip if RX-8 driver is not paying attention.

i totally agree with you. why does camaro SS, mustang GT, 370z, STI,challenger R/T, sell more over the rx8, and they all cost more than a rx8. thats where the rx8 should be priced with a turbo. people are paying 35k all the time for cars that like.

I don't know. The FD RX-7 was about 40k and it had good power for its day. It didn't do too well.

It's not like you can't pay that extra and turbo the car now. There appear to be pretty good solutions out there currently.

what put turbo of a rx8 and keep the boost within safe limits, and only be able to keep up with a stock sports car lol. .... not worth it to me.

Seriously? With my 8 at least, it's at it's best 50-90, third gear pulls hard. It sure as hell doesn't have any problems with passing, if I jump into the passing lane and gun it the car I was behind is practically a blur by the time I clear it.

Not even close, a stock MT 8 does the 1/4 mile in about 14.5, at best. It's been proven again and again.

I thought I accounted for that, but sometimes I forget that 1995 is already 15 yrs...
I guess present equivalent value would be close to $60k.

Dude, those are top gear times, not true 50-70.

It's has plenty of power to pass trucks, just not enough to satisfy the insecure types...

Mazda already knows how to turbo a rotary and they already developed a turbo version of the 8. Now if you'rs saying a turbo renesis would be less reliable than a non turbo, I can't say I agree wholly with that. The rotary isn't the most reliable in any iteration so why not turbo it. Most likely, the main reason we didn't see a turbo renesis is because of emissions. I don't think Mazda, when they decided to make the 8 NA did it because they thought it would sell more. The 8 didn't sell well and Mazda had many years to correct its perceived weakness, and the biggest one is lack of power.

Mazda should develop the 16x with a turbo version from the jump so as to not repeat the same mistake. Rotaries make little torque, and the great equalizer has always been turbocharging.
Side exhaust port has really poor flowing characteristics, think of the exhaust gas gotta take a 90 degree turn before it can get out of there.

if they add a TurboCharger in the exhaust path, there will be even more restrictions which might result in even more issues.

Emission has been a problem for Rotary since day 1, the side exhaust port alone can cut emission by around 50%.

if they can port the exhaust at factory it will help a lot, but that will drive the manufacture cost significantly (both time and f-xkups)

and Mazda learned its lesson back in 90s, they "can't" sell a car that cost too much.

16x will have Aluminum side plates, which is much lighter (about 11 lbs compare to cast iron like 20 ) and I assume they will use plasma sprays like RB has been doing for decades, which should be much more reliable than cast iron + gas nitrite.

as for "reliable", too much variables, some already got over 200K without single issue. some died in couple thousand miles (if not hundreds).

Sorry to say but no one will buy a "Mazda" for 39K when you can get a "Porsche" for just a bit more. (back then

2nd thing is back then not that many people "knew" about the power of the FD.

If right now I'm telling ya I give you a Mazda Rx-8.375 it has 350-400 hp Twin Turbo Rotary for 80K. would you buy it ? that's Cayman's price point. maybe you would, but 99% of the people wouldn't.

caymans.... 80k is 911 territory lol.... caymans are like 60k.

madza is not selling that many rx8s right now compared to other sports cars. that cost even more. so just because rx8s are a little cheaper, that still is not helping there sales when theres cars that are much faster, with decent handling. they better make a more powerful rotary or not sell them at all.

The problem is you start looking at other cars once you approach the $40k range you're looking at competing with even more cars that would also hold "status" that Mazda doesn't. While the true enthusiasts would still consider it, most would start to look at cars like the 335i instead. As much as I love the 8 and the rotary, I would probably have to pick the 335i over a turbo 8 if the pricing was close, especially knowing what we know now. Reliability would absolutely be an issue. Maybe you don't remember, but they kind of screwed up the reliability of an NA engine with the first years. Imagine how that would have gone if they had an FI version as well. I also think you're underestimating the costs of developing an additional engine set up that also accounts for reliability, especially with FI. I may be wrong, but I expect a factory equipped set up costs more than an equal set up would cost separately.

With the 16x, it depends a lot on the actual specs. Until we see production numbers, it's hard to say whether it needs more or less power. Depending on the weight, it could easily get by with NA power.

Mazda cannot sell an expensive turbo rotary. They've proven that the hard way. Don't expect them to make the same mistake again.

We'll be lucky to see a new 16X rotary at all, given the global economy and gas prices. Don't expect another Porsche-killer like the FD, it ain't gonna happen. Adding a turbo will price them out of their brand, and Mazda knows this now.

Ooops. my bad. wrong numbers

but point is still the same.

Rotary does not sell ---- the biggest problem is marketing/myth/word of mouth. dumb people always talk **** over something they know nothing about,we even saw a lot of them on this forum.

Plus to be honest, the lack of torque really kills it. I mean for me, my car pulls hard anything after 5-6 K on 3rd gear, but when you go have a test drive, how often would you pull it hard hard in 3rd gear?

Warranty issue ---- but we should blame this on "GREEDY" dealerships, they just wanna milk every single penny out of the customer's pocket, but the worst is, most of these idiots/wrench monkeys have ZERO idea how to fix a car, they just know how to read service manual, and always throw random parts here and there and "hope" it fixes the issue.

ok, enough of this talk, lets go back to ... Is the 8 really all that slow ?

If mazda made a Mazdaspeed RX8 from the factory that made say 350 hp and 250 ft lbs and only sold like 1500 in NA I believe they would sell out, even at 40 grand. People pay over 40 for an Evo. I've seen Chargers over 40. I don't think Mazda could sell a lot of turbo rotaries, heck they can't sell na rotaries, but I'd love to have the option.

They Mayans predicted the world would end in 2012 when Mazda would release a Mazdaspeed 8. The shockwaves of such a car would rip apart the fabric of reality and destroy the world.



True story.

Only an idiot would pay over 40k for an EVO or Charger.
