Can someone redpill me on the Mazda rx-8? I've always been

Just get a Miata like everyone else on /o/.

>redpill me

Go back to your cesspool

>>>/pol/

redline me on apex seals

>>17291118
Don't do me like that s/o/viet. You know I'm just using 4chan language. I guess I should've just said "enlighten me".

>Some say you have to baby the engine

Opposite actually, you need to redline it on a regular basis to prevent carbon buildup on the apex seals.

Keep an eye on oil level, I lose about 1 quart every 2k from the oil injection.

Premixing is mandatory if you want it to last a long time.

Flush the coolant every 30k to prevent water seal failure.

Change plugs every 20k.

Oil every 3k.

Redpenis me on cars that break down all the time

>>17291126

Also do not use that thin as fuck 5w20 mazda recommends, it's too thin to adequately protect the main bearings.

Use at least 10w40.

fuck what is wrong with the RX8? that is a retarded amount of shit for a street car

>>17291136
Not really, very easy shit to do

>>17291141

If you put a car into general circulation that requires you to redline the engine, premix oil, add oil that burns off and use oil that Mazda does not recommend just to keep the car in good working order

you are going to wind up with a bunch of cars out there that are fucked up

>>17291149

>use oil that Mazda does not recommend

mazda only recommended 5w20 to meet the minimum fuel mileage requirements.

In reality that thin shit will cause premature main bearing failure.

>>17291153
>car manufacturer tells you to do something to maintain the car they made
>you do it
>bearings fail

sounds like a solid business plan

>>17291108
You get a rx8 because you like the car or really like rotary engines. This is not a car that you simply put gas in and drive.
>>17291126 gives the general outline on what's needed to do. Also, there is a reason why Mazda has ditched the rotary engine, the technology is just too outdated.

>>17291136
>that is a retarded amount of shit for a street car
oil is easily changed, as are spark plugs, coolant doesnt have to be flushed 30k but its not a big task or anything
premix is annoying as hell, but not necessary if the oil metering pump works fine

basically... spend a single sunday morning doing easy maintenance on your car every few months or take it to a shop. how horrible

>>17291219
When the salesman sells an RX8 to a normie does he expain how the car must be premixed? That he must rev the engine to redline sometimes.. And that you can't follow Mazda's recommendation on oil weight?

or does he just sell the car?

because if he just sells the car you are going to wind up with a bunch of fucked up RX8s out there and a bad rep for the platform

>>17291240

>>17291136
If you aren't regularly checking your oil level even if you daily a 1.4L econoshitbox you don't belong on /o/.
OP if you live somewhere with cheap gas and you know how to maintain a car, go for it. Even if the engine is going bad after a while, who the fuck cares. RX-8's are dirt cheap and you can get 6 of them for the price of a new BRZ. The only reason I don't have one is because I'm saving up for a low mileage and well maintained FD.

>>17291299
>Even if the engine is going bad after a while, who the fuck cares.

Yeah why would I not want a car whose engine burns out all the fucking time

that's a benefit not a drawback, rite?

>>17291314

Don't care if this is a mem-post, since these threads are made literally once per week. I'm going in.

>Redpill me

You can find an RX-8 for super cheap, but they WILL have a bad or dying motor. That being said, RX-8's are cheap to rebuild, ~3.5k for a reman. There are plenty of good rebuilders, find one based on your location.

If you want one that is already in good condition with a fresh motor be prepared to pay ~7-8k.

All this in mind, these cars are not cheap to maintain nor do they do well with owners on a strict budget.

Things to understand: you can absolutely daily drive these cars, but you have to keep up with maintaining it. These cars have absolutely terrible OEM ignition systems. This first thing you should do even if you have a fresh motor is replace the coil packs, plugs, wires, starter, and battery with something better, BHR has an overhaul kit for example.

Second, make absolutely sure that you use ethanol free 91+ octane gasoline with this motor NO FUCKING EXCEPTIONS. In addition to this premix your gas with a good 2-stroke oil. Idemitsu is preferred, 4-6 oz per full tank, more if you've just run zoom zoom cleaner or seafoam through your motor.

Make sure you drive this car every. single. day. Do not let these cars sit, because then they'll stay wherever you left them. They are prone to carbon buildup and love to be driven. There's a saying in the rotary community: "A redline per day keeps the mechanic away."

All that being said, never, ever, ever redline to 9k and then try to hold it there. You will blow your fucking motor so fast your head will spin.

Moreover, these cars cannot be cold started and then promptly raced. Never race the engine until you are within operating temperature. If you take my advice from before and upgrade your starter, preferably to the R3 starter, you will have less problems starting when hot after your motor starts to lose compression.

cont.

>>17292155
If you don't take my advice and stick with the OEM starter, specifically on a model before 2009, make sure that if you drive too short of a distance to get your car to operating temp you stick it in park, swap to neutral and rev to 3k for 10 seconds. Wait a minute and then do this again until the needle is near the center of the temperature gauge. This will prevent flooding and fouling your spark plugs.

Make absolutely sure that you keep your car below ~5k RPM when it's cold. The fuel system will even cut you off if you try to race the motor much higher before it warms up.

Never, under any circumstances, consider buying the A/T variant of any year RX-8. They are weaker, more unreliable, and have a slew of other issues I won't cover here. All manuals are 6 port engines. All A/T's are 4 port. If that doesn't convince you alone I don't know what will.

Finally, make sure to never overfill the oil on cars before 2009. The excess will wind up in your intake if you don't build yourself a catch can. Clean your MAF sensor every time you change your air filter.

If you aren't a dumbass, this will be one of the best cars you ever own. The engine can last well into 150k territory depending on what mileage you get the car and when you start taking care of it correctly. They drive like a dream, the handling is not a meme, they are my favorite thing to autocross by far.

If you do wind up having to do a rebuild it's worth mentioning that goopy seals are the way to go these days. They make future rebuilds much cheaper as they don't shatter and score the rotor/housings.

Hope this helps.

>>17292155
>>17292175
someone screen cap this repost it every time this stupid fucking question gets asked.

>>17292175
When putting in a new motor what kind of streetable horsepower can you make?

>>17292180
Depends on the type of port you have done. The seals won't really change your available power besides restoring compression to the point where your engine's spec'd horsepower is restored.

Porting will changing your air and exhaust ingress and egress and will completely alter your power bands as well as how much horsepower is available to you.

Streetable is a loaded question. Porting can make your engine last less long than OEM ports, depending on what you go for. You go in expecting this, hence the rise and popularity of goopy seals, which again can save the reusable parts of the motor from being destroyed.

You must understand that turbo-charged rotary engines, while great for motorsports and spirited driving, will not last as long as turbo-charged piston engines. Fullstop.

>>17292200

The thing is they are like 220hp and get 16mpg city, I fail to see the appeal of this car at that power level and maintenance level

what is the point

it looks to be a high 14second to even 15 second quarter mile car

>>17292219
>220hp and get 16mpg city,
kek that is shitty

>>17292219
If you fail to see the appeal of it, then don't get yourself into it. That's the point.

This car is not fast. It's much harder to modify than a civic si. It's not cheap to get horsepower gains. It's slower than most RX-7 variants and harder to mod.

Things that it is: amazing for spirited driving. The platform is impeccable for taking turns, the rotary itself allows for a low center of a gravity and is very forgiving during autocross. The car can accelerate, as most rotaries can, very quickly. Finally, for a rotary it's much more practical for daily driving and very day life.

If none of those points appeal to you and you just want to make horsepower for drag racing around your local high school, stop looking at RX-8's. Plain. and. simple.

>>17292226
16 is high for city. Most people get ~13. Gets worse as your compression goes.

22 is average for highway. Again, gets worse as your motor goes.

I will reiterate. Not cheap. Rotaries should be for those enthused about them and those enthused about them exclusively. They will disappoint all others.

>>17292235
>The car can accelerate, as most rotaries can, very quickly.

I know you are joking but this is literally the vibe I am getting, it's like he likes it because it's got horrible stats and needs constant maintenance

are they just in love with the idea of a rotary engine no matter how poorly implemented?

>babying a rotary
Surefire way to end in disaster. You absolutely cannot baby a rotary. You actually have to redline it every so often in order to get rid of carbon deposits, otherwise it will fuck your engine's shit right up. If you mean "baby" it by mixing the 2 stroke engine oil with it then yeah.

Also take out the oil injectors if you don't want to lose oil. They're useless anyways.

>>17292312

Rotary engines are garbage and are not practical in anyway. If you seriously want an rx, go with the rx7 turbo.

>>17291125
It's fine, he's just being an autist

>>17292175
>The engine can last well into 150k territory
This is my biggest issue with rotaries. I can simply change my fluids every 6k miles and most non-rotary engines can easily do 150k. Honda and Toyota engines can easily hit 200k+. And all this is done by simply changing the fluids at regular intervals. The rotary requires much more work to get the engine to last. That being said though, I love my rx8.

>>17292732

For those who don't get why people like the RX8 here's the deal.

Go look for them on ebay or craigslist, they are cheap as fuck.

So poorfags buy one for a few grand and learn to live with it, since they are poorfags they have never driven a fast car before and are super fucking impressed with 200hp and 13mpg and 0-60 in 7 seconds.

So they have a car they could not afford if it were not toxicly plagued by it's engine and enjoy the nice interior and low to the ground seating position (just like a real sports car!) and live with mixing oil into their gas and having to slam their balls in the door twice every time they get out so the rotors wont sieize up and convince themselves they have a nice car

but it's really just a failed experiment by a car company that left a bunch of cheap underpowered high maintenance cars out there with nice interiors for the poor to deal with.

It's the perfect car for a young /o/ poster to marry

>>17291108

The problem with the RX-8 is that it is an enthusiast car in a normie package. As a result, you have a lot of people buying them who don't know fuck all (and more importantly don't care to know) about the intricacies of rotary engines. They don't premix, they don't re-up on oil, they don't do a fucking thing other than drive it until it explodes.

>>17292875

the problem is it has 220hp and gets 13mpg and would get smoked by a honda accord that gets 30mpg

Rotary a shit

>>17292875
>lot of people buying them who don't know fuck all
This.

OP if you're seriously considering buying an rx8, make sure the seller knows his shit about rotary engines. Compression test is an absolute must when buying an rx8. Take it to rotary mechanic, and if you can't find one most Mazda dealers will inspect it for you for a fee. Rx8s are still owned by a lot of normalfags so you need to make sure you are not buying an rx8 with low compression and apex seals that are almost dead. Most rx7s are owned by enthusiasts so you don't need to be as cautious.

For fuck sakes, there might as well be a sticky for rx8s and why there shit so we can avoid the daily "hurr should i an rx8, they're cheap and have meme wheel drive, so they're good rite guise?" Thread.

You're damn right I'm mad

if mazda were smart they would have put the renisis in a miata sized chassis.

thats when you see the benefits of the rotary. the motor is super short, doesn't weigh a whole lot and in a light weight platform you don't need low rev torque.
the rx8 is unimpressive because mazda tried to make it do everything. it is the size and weight of the chassis that kill the idea. seriously mazda would have made a great car if it was just a hardtop miata that looked better and had the renisis.

all that said I'd still buy an rx8. there is something about the mechanical efficiency of a rotary thats really intriguing

>>17294186
The tech is absolutely outdated

its designed to burn oil, emissions are terrible because of it and all this combined means it gets ASS mpg.

Its a gimmick people like you try to uphold because you want something different from a traditional pistol engine and nothing more

except it gets NONE of the benefits of a low weight car which is agility, mpg and efficiency. This car is highly inefficient.

>you don't need low rev torque
what are you talking about, without torque you have no power. Without torque you can't accelerate quickly, torque is literally the leg of power derivation that allows for quick acceleration.

>>17294296
>mechanical efficiency of a rotary thats really intriguing

I agree with everything else you said, but how is a 1.3 liter motor that gets 13 mpg, burns oil, and makes 220hp efficient?

You are burning the fuel used by 500horsepower V8s while making less than half the power and requiring more maintenance

that's inefficient

>>17291108
You get like 80k-100k per engine and they are $6,000 to replace, everything else is completely reliable as far as I know. It's a perfectly fine car to get as long as you are aware that you Will be replacing the engine.

tell me how this design is efficient in any way at all outside of volume that doesn't really fucking matter anyway?

>>17294307
remember I said putting the engine in a miata sized package
In a sports car you start to worry less about mpg. agility would be better then nearly every car because of how compact, low and short the motor is. because of the reduced weight it would be a bit more efficient because the lack of low rev torque would be less apparent. thats what I think makes the car get such bad mileage.

>what are you talking about, without torque you have no power. Without torque you can't accelerate quickly, torque is literally the leg of power derivation that allows for quick acceleration.
I said low rev torque. A light car doesn't NEED low rev torque. sure you can argue that having it is better but I'm not saying that the rx8 is better then the corvette. I'm saying in a small light chassis the renisis would not seem as flawed as it is. and yes torque is what power derives from but renisis makes all its torque closer to the redline.
>>17294318
I said mechanical efficiency not general efficiency. something that constantly spins and simply changes speed is more mechanically efficient then lumps of metal that need to stop and start hundreds of times a second. I will never argue that in its current form that the rotary is in any other way more effiecient than other engines. It's not.

>>17294332
>J37 from the TL SH-AWD
what does this even mean

>>17294370
>remember I said putting the engine in a miata sized package
none of that would change the fact that the engine is extremely inefficient. That miata engine will go farther, do better and be far more usable and not burn ludicrous amounts of gas, oil and shit. Putting an LS1 would make more power and it would still get better gas mileage and not burn oil even if it was a lot heavier

How do you differentiate mechanical efficiency from overall efficiency?

The spinning crank and flywheel on a piston motor would appear to be more mechanically efficient than the rotary

its not mechanically efficient. Everything to do with energy efficiency is out the window which means your "mechanical efficiency" doesn't mean jack shit.

>general efficiency

efficiency is efficiency, there aren't any different kinds when you're talking about this shit. The car/engine is efficient or its not, the only metric people use for measuring efficiency is energy based efficiency.

>>17294393
No, why would you think that?

>>17294384
>How do you differentiate mechanical efficiency from overall efficiency?
You don't, hes fucking retarded and can't into thermodynamics.

A piston engine will always be more efficient than a rotary, unless rotary has some amazing fucking revolution, its not efficient in any meaning of the word

>>17294378
Holy shit man
I even said
>I'm not saying that the rx8 is better then the corvette.
Yes its inefficient. so is my 4 banger piston engine that makes no torque and needs to be revved to the moon to make power. But it suits the car its in.
Mazda has heritage with the rotary. It's like porsche and the 911. So all I'm saying is that they should have been smarter and put it in a car that hides its flaws. In the exact same way that porsche continues to develop the 911 and work around its flawed engine placement.

>>17294404

>>17294415

that 4 banger is far more efficient than a rotary is.

who fucking cares, its a garbage design. No one gives a fuck if its something they've always been able to do

No you're fucking retarded to think the rotary is efficient in any fucking way

Efficiency is all about energy in and energy out and the amount of energy lost in the intermediate as heat. This is the only form of efficiency people give a shit about

Mechanical efficiency or "general efficiency" is not a fucking thing, its just efficiency

You pour 6 oz of 2stroke oil in the tank every time you fill it up

the RX8 burns oil and needs this

>>17294484
How does this supplement the oil injector if it constantly injects oil anyway?

>>17294478

Torturing 1.3 liters to put out 230hp at the expense of longevity and fuel consumption and heat generation is not efficient.

If I could make a 1.0 liter engine make 300 horsepower while getting 10mpg around town and needing to be rebuilt more often than any other motor.... would that be efficient?

>>17294497
>How does this supplement the oil injector if it constantly injects oil anyway?

what do you mean how, by being mixed with the fucking gas is how

also the oil injectors don't work very well, that's why you premix

>>17294505
Well the oil injectors inject oil at a constant rate assuming they are working.

>>17294513

It's been found the engine will last longer if you premix

Out of curiosity, would any engine benefit from having a bit of 2-stroke oil mixed into the gas?

I'm wondering specifically about 4-stroke motorcycles where it's not a big deal to do.

12a owner here

It's exaggerated a little bit, but the rumors are true. It has a pretty strict maintenance schedule and even when you follow it, that's still not enough. Rotary owners will tell you shit like "wow every car should have the maintenance followed perfectly" and while that's technically true, the main difference is that with a normal engine, you can delay your maintenance a little bit (or if you have hardly any mechanical sympathy like normies, you can delay it alot) with no problems. But with a rotary engine you can't.

It's like a toddler in the kitchen, lots of energy but you gotta keep your eye on it cause if you stop paying attention, the little shit will turn the stove on or something and leave it on.

>>17294541

Not really, it's the way the rotary works specifically that allows the oil to be useful, a 4 stroke piston engine will just intake the oil as mist , burn it, and push it out the exhaust without it doing any good

>>17294541
If you're having low compression issues with an older engine, you can apparently mix in some 2-stroke and it'll help out

>>17294582

I wonder why the EPA and US Government let them make an engine that injected oil to be burned into the engine?

Especially when it was for a totally unneeded sports car- not to make some needed thing function

kinda weird

>>17294598
In a piston 2-stroke is the lubricating effect of the pre-mixed gas solely from when the fuel is being pressurized in the crankcase, so is it also from when it's being compressed in the cylinder?

In a four stroke rotary why wouldn't it be analogous to four stroke piston engine? If it'd just burn up in a piston four stroke, why would a rotary be different?

>>17294604
Well, they didn't let them off easy. In my FB I took out around 50 pounds worth of emissions control and vacuum hoses when I got a mikuni carburetor. The engine bay was totally packed full of hoses everywhere (called the rats nest) and now it's really empty, you can actually see the engine underneath it all, just compare it to a stock FB engine bay.

>>17294617
Along with lubricating the seals, the oil is also what makes the compression. A freshly rebuilt engine won't even start unless you put some engine or 2 stroke oil down the carb or in the spark plug holes first.

So is there any downside to putting 2stroke oil in a four stroke? If all it does is increase compression (the extra lube isn't needed) that's still a good thing.

>>17294660
I have no idea, I've only heard about the compression thing as a trick to help an old piston engine but I've never done it.

I have an old 4-stroke dual sport with a big safari tank, so if it extends engine life and improves performance it's hardly any expense or hassle. But not sure if it'd fuck anything up, like the carb or the fuel filters.

Btw, what does 2-stroke oil do to octane rating?

Late to this thread but just want to put this out there, i work at a Mazda dealership and I don't believe we have any mechanics left that can rebuild rotaries (or do it correctly at least). That being said, we have about half a dozen abandoned Rx8s sitting in the parking lot that have blown engines. They're just rotting away in the sun, been there for the entire 2 years I've worked here. For what it's worth, I think rotaries are awesome but certainly not worth the headache of owning one now that they're all neglected and worn out. I could see having a track/weekend car with a new rotary engine in it and just keeping up with that, but don't buy a used RX8 and expect to daily it or anything.

>>17291126

This.

I've got a br/o/ in the same office block as me that owns a GenWun RX8. Got it at 60,000kms, now has 160,000kms on the clock.

Runs premix, and still has perfect compression.

>>17291126
How long have you had your rx?

>>17295262

4 years, got it with 46k miles.

Never buy one with a shit ton of miles on it unless it has had the engine replaced under warranty.

And paperwork to back up the mileage on the new engine.

>All A/T's are 4 port. If that doesn't convince you alone I don't know what will.

Only up until 2006, when Mazda switched to the 6 port engine for the automatics.

>>17291123
they'd blow before then

I will never understand rotary fags who claim if you take care of the engine it will last for a long time. Everyone knows the rotary engine is the complete opposite of reliable. A maintained honda or even toyota engine can easily get 150k, and in some cases can hit over 200k miles. You can have the best maintained rotary engine in the world and it WILL shit the bed around 100k. The only advantage to rotary is when it breaks they are cheap to rebuild.

>>17291108
It's the car Vin Diesel raced in the Fast and the Furious so that automatically makes it the best car you can get.

Here are the costs you should have over the first 30,000 miles
- 1,764 gallons of gas - $5,294 (using 17mpg and $3 per gallon)
- 40 quarts of oil for oil changes - $160
- 10 oil filters - $120
- 30 quarts of oil to top off with - $150
- 4 spark plugs - $80
- 4 coils - $140
- 4 plug wires - $60
- 4 tires - $800
- 2 quarts of transmission fluid - $20
- 2 quarts of rear diff fluid - $20
= $6,844

Please tell me why the fuck ANYONE would ever buy an rx8. This is all on top off having an engine that could die within 50k miles.

Miatas are so meme taxed that you could get a BMW z3 for the same price as a miata in the same condition

The only way miatas are cheap now is if they're fucked in a way that is a genuine expensive PITA to fix (body/paint damage, interior falling apart, ripped up softtop, bent frame but no salvage title because single car drifting accident that could be driven away from)

It's like a slightly more powerful GT86 for less than a third of the price, with significantly less gas mileage.

(If you want a car with good gas mileage, don't get it.)

Also requires that the owner do the following:
>wait for the engine to warm before driving it
>redline at least once per drive
>drive often
>go no longer than 3000 miles without changing oil

(If you want a car without having to think about preventative maintenance, don't get it.)

Additionally, some are in much shittier condition than others, so buying one that's been properly cared for is key. To do this, avoid the 04/05 models because of their ECUs' faulty oil injection, and do a compression test before buying one.

(If you want a car without having to research it before buying, don't get it.)

Lastly--just like the GT86--it's not a fast car. It won't win any speed competitions. However--also similar to the GT86--it does have pretty good handling; which makes it fun to drive for people who are into that.

(If you want a fast car, don't get it.)

>>17294513
they do not provide enough oil to adequately lubricate all of the seals, unless you have an 08+ model or whatever

>>17299342
The rx8 looks fun but the fact you can get a gt86, which does everything the rx8 does but better, makes me wonder why anyone would buy an rx8 outside of it being cheap.

>>17299551
what exactly does the gt86 makes better?

>>17299560

>>17299551
The main advantages the RX-8 has over the GT86 are the slight increase in front and rear legroom, the rear doors, and the small bump in HP. The increased amount of gas used is negated by it being so much cheaper.

Performance-wise, they're about equal:

I guess this thread is officially dead. I'm sticking to the rx8 forums and getting some more information before I decided wether or not to get an rx8. To those of you who posted actual information, thanks I appreciate it.
