im looking for an NEW rx-8 not rx-7 i love every feature of the rx-8 minus power wise but is satifying.. IMO i rather them improve the rx-8 rather than comming back out wtih the rx-7 not really feeling the 2 seat... also bigger rotar 1.5L that would be a dream, FI would be nice (only cuz i absolutely LOVE the sound of blow off valves) but i would like to see it somewhere around 300hp w/o FI.

i know there is a rx8 with a rx7 FD engine in it mabe the kid was talking about that
but its not mazda its custom
whats so bad about the rx8 anyways? few pounds heaviler two more seats two more doors an extra gear and a DSC for half the price of an rx7. geess we are getting a hell of a deal already
btw greddy makes a turbo kit for the rx8, probley instead of hopeing for mazda to make a faster car lets hope for tuners to make faster parts
cheers

My wishlist for the next RX-7/MS RX-8:
1. Use as many parts as possible from th RX-8, but shorten the length to make it a 2 seater
2. Shave 200-300 lbs off the current RX-8, 2700 lbs would be good.
3. Have a solid/beefy transmission capable of handling 500hp at the minimum.
4. Excellent handling, must be on par with or better than the FD
5. Power should be somewhat of an improvement over the FD, 280-300 hp sounds about right
6. If it has sequential turbos that would be the best, single turbo is good too, if it is N/A atleast make it turbo friendly as many will make it turbo anyway. Torque numbers are important and the turbo(s) would do well to boost those numbers.
7. Price should not exceed 40k USD, 35k USD sounds about right.
Hopefully with these specs the next RX-7/MS RX-8 will give considerable grief to Evo, STi, S2k, 350Z, and start creeping up on the C6.

My opinion is why would Mazda release another rotary car to compete with a rotary car they have out now? Also, in a way if they made a new 7 it would reduce sales from the miata as well, which is one of the best all time selling cars. It just doesn't seem like a practical business move to create unnecessary compettition within the same market for themselves. But, thats just my 2 cents.

Mazda already has 2 sports cars in their line up: the miata and RX-8. Both are excellent platforms. I think the RX-7 has passed the torch the 8. The 7 was awesome but I think the 8 truly is the replacement. Disappointments of no boost, low power figures, back seats, etc. I think are the reasons why everyone is looking for a new 7. But I think the 8 has proven it's worth. It already handles better than almost anything out there.
If a 7 came out, I WOULD STILL KEEP THE 8 (aside from still owing payments). To me, the 8 is suffering the same thing the 7 did. The 7 was against the Supra TT, 300Z TT, Skyline GT-R (RB26DETT); notice the trend in TT. And at that time, 7 was lighter and had lower hp figures than those cars. The 8 has the same dellima; the STi, EVO, 350Z; two are turbo and one large displacement, but all BEST BANG FOR BUCK. The 8, rotary power and dynamics at a cheap cost (BEST BANG FOR BUCK PERFORMANCE).
Anyway that's how I feel. I know I'm going to get flamed for these comments. Where's my fire suit.

A MazdaSpeed RX8 LE would be a good idea
The RX8 is an amazing car. Improving the 8 is a delicate task, throwing a turbo on it is cool, but it raises the specter of decreased reliability. Mazda does not want the reputation of making unreliable cars, because one unreliable (especially the flagship) model can blemish all the manufacturers models.
I'd love to see a Limited Edition RX8 with a third rotor, the extra weight could be offset by removing the back seats, the near 50/50 weight bias could be maintained by relocating the battery and some other engine bay items to where the rear seats were. The current MazdaSpeed suspension components could be used to improve handling, and a little carbon fiber (hood, trunk lid) to drop weight. If the transmission can't handle the third rotor, it would need to be strengthened. The extra 100HP would move the car into the next performance tier, taking on cars like the Z06, Carrera, etc. without compromising reliability.
The only downsides I see would be higher cost and lower gas mileage. If the car was given a limited run, it would be considered a collectible. The gas mileage and extra cost would not be an issue, given the LE status and performance. The extra cost would probably put the car in the mid 40's, which in my opinion, is not too expensive.
This car would not take away sales from Mazda's existing models, I think it would actually increase sales because of the buzz generated by the performance.

What a thread revival...
Not much word on a possible next 7 in JDM mags. Mostly just the upcoming GTR, Evo and STi.
3 rotor Renesis? Even RG said it can't be done. The intermediate housing has siamised exhaust ports. Make it a 3 rotor and the middle rotor won't have the same flow characteristics as the front and rear rotor (all of it's exhaust ports are shared). Add to this the heat issue... it seems highly unlikely.
Wider rotors? This would seem like a more likely solution for more NA power. However it will require a bit of reengineering and retooling. New rotors, new housing, and changes in porting. This will likely also lower the engine's redline with the increased rotor mass and what effect will this have on the life of the engine bearings?
Turbos? I'd say that it is probably highly unlikely. The biggest issue is emissions... namely initial cat light off. I don't remember the specifics, but it's something like the car has to pass emissions within 5 minutes of startup... thus the cat has to be up to operating temp in that timeframe. With a turbo sapping heat from the exhaust system... it'll be a task to make this pass emissions. Let's also not forget the lack of space under the hood...
Supercharger? This seems like the most likely scenario for more power for the 8. Initial reports all say that the Renesis responds REALLY well to supercharging. Supposedly it's driving characteristics are much better than the GReddy kit... from low to high-end. Also considering how much Ford seems like to like S/C over T/C... using the parent company strength to get a deal on a twin screw S/C ala Mustang Shelby GT500 or Ford GT woudl also seem to lend weight to this possiblity.
Consider the competition... Well according to JDM mags the 350Z gets some minor costmetic changes and more power for 2006. The Supra is rumored to return... NA V8 is what they say. Pricing would be e90 M3 at worst, but I'm better on RX-8 neighborhood. Don't forget that the new GTR will be an Infinity and Lexus has their supercar coming out. Honda is definitely working on SOMETHING as a replacement for the NSX. A Mazda flagship? Well Mazda really need to work on making sales with what they have before going for a new "halo car".
We'll see what Mazda comes up with by the end of 2006.
Personally, I'd like to see more power in the 8 too.

I like your mode of thinking.
For the longest time, I have been proposing in my head the thought of another RX-7 model.
Use a 3-rotor n/a motor like the renesis. Have a rotor cut for light load conditions to improve gas mileage (or "help" in this case). Use a 6-speed (or maybe a 7 speed!!??) transmission to relieve throttle input in city commuting.
Use the Rx-8 platform and suspension, but of course shorten the wheelbase and lightly increase track for more exciting feel. You could easily shed 200lbs. from what the rx-8 carries, to bring the weight back to FD specs. 6-8 piston brakes up front and 4 piston in the rear, with 13" rotors. 19" forged wheels, carbon trunk, aluminum vented hood, 2 seats.
So, 350hp, 2800lbs, 6-speed, massive brakes, 2-seater coupe. I smell a C6 and porsche circuit smasher. I myself would pinch my pennies to fork out about $40-45K for something like that. Sti's and Evo's would run and hide.... remembering that they are still just souped-up sedans, and not pure-bred sports-cars. We could see possible supercharged or turboed versions of this new RX-7 tearing the vettes and vipers a new arsh on the Speed Challenge and FIA circuits, oh yeah, and another Bathurst edition to take on the new GT-R (only with two less wheels applying power).
I truely believe that mazda has what it takes to put all other sports car in-class to shame. The Rx-8 is awesome, and is really held back in a big way, so they need to show their real cards and lay it down!
Also, to note: The FD3s RX-7 series VIII was the next best thing to the R34 GT-R over in Japan. Put them side by side on same tires, around a well laid-out track (like Suzuka or Sears Point) and the FD will be nipping at it's heels. Mazda needs to show that they can still hang.

i got my wishlist too:
the motor from the MS3/MS6
but to all seriousness, i wish mazda had the option of having piston motors in the rotary powered cars (or the other way around, depending on the way you look at it) the way they did back in the 70s with the RX-2, RX-3, RX-4.

Everyone in those older posts didnt do anything but agree with each other about the unlikelyhood of turbo's and how they alll thought an upgrade in power would be bigger displacement. I know this is an older forum, but it wasnt that old. Turbo cars have made huge advancements these days, Audi's love of it, and have great reliability. STI's and Evo's have brought turbos out of the tuner and exotic markets, and shown car companies that turbo's are a good way to get more power while keeping weight down, and it definately appeals to the future markets. As fuel economy becomes bigger and bigger, you wont see increases in displacement purely because bigger displacement means more weight. Weight kills milage.
