What is /o/pinion's on the Mazda RX-8? I'm seriously

Does it have any advantage over an RX7?

Have extra money on hand for an engine rebuild. I know it sounds like a meme, but these things really arent taken very good care of.

Check the odometer and if it's over 80k, don't get it unless it's on it's second engine

prepare for premixing

Other than that, super fun car and you will love it

Oil and fuel economy can be a bitch and it does depreciate like a lead balloon.

>>14718821
you think someone in the market for a *used* rx8 can even consider an rx7, let alone find one?

stop your memeing boy

>>14718789
Cheap trackslut.
Wankel engine brings high fuel consumption, continuous oil consumption, and a maintenanve routine that you have to stick to. If the PO didn't, you could be in for trouble. The Renesis units weren't the most reliable of the Wankels, and certainly not the most powerful thanks to the lack of turbo's, and the chassis is heavier and less rigid than the FD, but then again, the RX-8 is a lot cheaper.

>>14718833
Theres already a rotary thread. Why not ask there where like-minded people will give proper answers.
>implying FCs and FBs are expensive

>>14718843
At least in my area, rx7s of any year are nowhere to be found

>OP asks about RX8
>some faggot bursts in telling OP to take a look at some different cars (which are ugly and inferior to RX8)

>>14718815
This. Bring a contingency fund, just in case.

>>14718816
If it's over 80K, and has been taken meticulous care of, you can still go for it.

>>14718831
Depreciation won't happen, they're dirt cheap now. They might actually appreciate soon, following the FD, as a driver's car in their own right.

>>14718843
FC's and FB's are in a completely different league from an RX-8, in age, power, reliability and styling.

Should have had a piston engine desu.
All of its vices stem from the dorito under the hood.
Rotards will try and deny this, but they know it's true

>>14718881
Mazda had no better engine to put under the hood at the time. Certainly not as powerful.

>>14718880
I just say 80k because it's safe to assume that most people don't meticulous care for their cars, but you're right

>>14718856

Mazda was stupid to put a rotary in a mass market car, they should have kept it for a flagship sports car

PO's didn't take care of them. That means everything is going wrong or will go wrong very shortly.
IIRC the engines aren't great for making power either.

It would hinder its perfect weight ratio, also it's a rotary/RX7 successor and muh heritage.

that was my mistake, but either way the latter two cars are no way comparable to the rx8 other than engine (>>14718880)

It should never have been an RX.

Wouldn't have the n/a response of the Renesis. Let me rephrase it: Mazda had no n/a engine suited for longitudinal, front engine, RWD application at the time.

>>14718939
To be fair, the RX8 could've easily been the MX-5's bigger brother(MX-8?) instead of the RX-7's sorcessor. Weight ratio can be influenced by things other than engine layout, a transaxle layout (924, 'vette) would've been possible.

Oh trust me, I'd love a 2.3 turbo MX-5. It's just that putting one in a RX-8, from the factory, would've gone against a lot of Mazda's design goals.

>>14719008
Both the RX-8 and Toyobaru should've come with FI (at least optional), but in both cases FI conflicted with design goals.

Mazda produced a concept car with this configuration in 2006

I'd recommend you test drive it to be sure. It offers a particular thing and if you don't like it's thing you won't get on with it. It loves to rev and just keeps driving and driving - it shouldn't ever feel stressed or like it's thrashing or breathless. It just goes. There's no lag, no surge of boost, just foot down and drive.

It's a solid chassis - one of the best you can get anywhere. Very easy to drive fast. I was hammering it around mondello in the worst of conditions and it was planted. When it did decide to let go, it was never snappy or uncontrollable. It's an easy car to drive quick, and feels great brapping up and down the gears keeping the engine screaming. Cruising around down will foul the engine with carbon, so batter the bollocks after it.

Zoom-Zoom-BANG

I've taken mine around Mondello. To building sites with tools and equipment in the back. To car meets. To Cork for the weekend with friends in the back. On family holidays. Onto the beach. I've loaded it down for work. I've battered the bollocks out of it. It's done everything you'd expect of a daily car to do. I haven't preened on it or given it an 'easy' life - it's been well used for the last 2 years and it's run well through it.

It's a ten year old car so it'll always have a few minor bugs but so far, I can't complain. I blew a coil shortly after I bought it, and broke a suspension piece but other than that it's been no more or less reliable than any other ten year old car.

>>14719107
Is it reasonable to service/maintain?

Fine. Oil, plugs, filters, like any other car. It's fairly easy to look after at home - I can keep mine running myself. It doesn't tolerate being ignored like other cars might - especially the oil. Change it regularly or you'll clog the oil injectors and **** the engine. But it runs mineral oil not the stupid expensive synthetic stuff.

Otherwise just keep an eye on fluid levels and the like. Stuff you should do anyway with a car. 1L oil per 1000km is normal. It may use less. Might use more. Using none is a problem. Most owners at 2T premix to the fuel - between 100:1 and 200:1 normally, since it's designed to burn and engine oil isn't.

What kills them is ignition faults. The ignition coils especially are known to go, which foul the plugs, which then go on to torch the cat, which quickly cooks the engine side-seals. The seal spring overheats, warps, pops the seal out of the grove - it clips and exhaust or intake port, shatters, then it's all over for the engine.

Good news is, you can drill the cat and still pass the NCT. You'll also blast flames at people in traffic, backfire at high RPM and gas traffic. Maked people dive for cover.

A lot of owners will replace the mazda coils with D585's. With a dwell remap they can make a big difference to the car's lifespan and driveability. Adding little 2-stroke oil to the fuel will also help a great deal. Some owners run thicker 10w40 oil in the engine rather thn 10w30 thinking it helps the stationary gear bearings.

Just keep on top of servicing, keep an eye on it and it'll be alright. If it starts when hot and doesn't otherwise struggle it'll probably be fine. If the owner has their head screwed on they'll look after it - you can usually tell the ones who do.

Mine's due a service in the next month or so. New sparkplugs, new airfilter, fresh oil. Should see it right.

My mate has one, it's the 230bhp version.

Recently had it on a rolling road, and it had lost about 40bhp. It's 11 years old and has around 85k miles.

I would like to add on the same day, my s14a was dyno'd and made 260bhp, 60bhp over stock. 16 years old with 91k miles

How is the fuel economy?

Fuel economy is an oxymoron. Consumption around town is 20l/100k. On a motorway, it drops to 10l/100k cruising. If you're getting worse than that it's sick somehow. 9/10 it'll either be a dead cat, bad ignition or a fouled maf - the first will kill the engine, the second will kill the cat, the third is annoying, but makes for epic exhaust flames.

What Kills them?

The 2004 models came from the factory injecting too little oil into the combustion chamber - because someone complained about the press cars drinking a little when caned. With obvious results for the engine seals. They reflashed after a bunch turned up dead.

All models have **** ignition coils from the factory. Which quickly leads to catalytic converter death, which leads to engine death.

The fuel pump can be prone to overheating below 25% of a tank which causes it's output to drop. The saddle tank can also cause problems and suck dry at high speed in left turns. So, the fuel pressure drops....usually at full throttle. A sudden lean spike causes on-load detonation in the engine, with fatal results. Can go unnoticed until after the engine's rebuilt - and the rebuilt engine goes pop on the shakedown.

The stationary gear bearings are prone to ****ting the bed - especially the rear ones which is weird because they are the first to be lubricated. Mazda speccing too thin an oil seems to be the cause. Quite a few on Irish rotary have died this way recently. A lot of owners will use 10w40 oil to try preserve them. Potentially a lot of 'apex seal' failures are actually bearing failures. Might be a combination of the cooler Irish/UK climate and too big oil coolers keeping the engines too cold for too long.... nobody really knows.

The side-seals hate backpressure and heat. It's the other real killer of engines. When the cat goes it causes enough backpressure to bake the side-seals. If they get too hot they warp, push the seal out of it's grove where it gets dragged around the engine until it shatters, taking out the rest of the rotor as it goes out the exhaust. Some people use springs from the older FD engines thinking turbo springs might be tougher.

Too long between oil changes can cause the oil injectors to clog with sludge and starve the rotor tips of oil. Too long at low rpm can do the exact same thing. Or just jam the seals and keep them from doing their job. This is always your fault. But a lot of people either run premix or fit a sohn adapter to run the oil injectors off of a reservoir of 2-stroke.

A lot of these faults happened because Ford encouraged Mazda to save a few hundred quid per car...... and a lot of them are fairly easy to mitigate against if you take the time to read the forums.

In my experience, it's the sort of car that when I look around or something to replace it with, I find it very hard to do. There's really nothing like it out there.

It's a hell of a lot of fun to drive.

RX7Club disagrees with you.

Its a piece of shit
its a naturally aspergerated rotary
basically a 1.3 rx7 heavier and without its balls

I own a 1984 GSL-SE RX-7 with over 300,000 miles on the factory engine, which has never been opened for repairs. It does not burn more oil than the oil metering pump injects, and does not smoke. It still makes full power, starts up instantly, and idles smooth.

My father also owns an RX-8 with over 100k miles, and I have driven it extensively when I borrowed it for 6 months since he has too many cars to fit into his driveway. I also took care of it during this time.

Premix is only needed if you remove the oil metering pump. If you follow proper maintenance intervals and rebuild/replace the oil metering pump, premix is never needed for a street/autocross rotary.

The engines can last nearly forever if you take care of them. That is, use the right oil (No cheap synthetics or synthetic blends. Nothing with high ash content), change the oil, keep the oil filled, keep the coolant filled, keep the spark plugs firing. Seriously. Its that simple.

Also do some power runs regularly. As in, take it up to 8500RPM at full throttle a few times. Doing this can heat up carbon build up that gathers in the apex seal lands and burn some of it out. If excessive carbon builds up under the seals, they will not be able to compress into their land, resulting in failure. Many dead RX-8s were automatics and were driven by idiots (women) who never took the care up to redline. And as with any car, don't race it when the oil is still cold. Remember, oil takes longer to reach operating temperature than coolant, so a coolant gauge that has just reached the normal zone means still cold oil.

As long as you know what you're getting into and stay proactive with regular care, you should be fine.

I don't understand the renesis hate.

>unreliable
A 100hp 12a is more reliable, big deal. A ported 12a making stock renesis power is lucky to last 40k miles.
It can also make 270hp at the flywheel without engine being opened... Compare that to 260hp rew shitting its pants whenever its above 35c outside.
