What exactly is an RX-8 type S?

 

is the rotary durable compared to piston engines?
the original question was pretty simple and so far only two decent answers and lots of rubbish:
1. lemans
2. seals

and few rx7s at 150k dont prove anything since i can show you 10 civics on my street that did that with gas/oil/tires
and whoever made the comparison to an american brand car at 20k by my count indicated they're not reliable

can we ever have an intelligent debate?

 

Its like a RX-8 GT. Just a model designation in Japan and possibly other countries.

 

Actually the "original" post was: most ppl says rottary engines has shorter life than regular engine.....is it true?and how can i keep rottary engine last longer..??

And it was answered in the very first reply. Sorry that you felt it was rubbish, but it was true.

 

It will last just as long as a piston with proper care. I believe this was already said in an earlier posts and many other threads.

 

The way I understand it is, a N/A rotary can last as long or longer than a piston engine if you're just driving around. If you're talking about driving around at the maximum rated power, then the rotary will last far longer. Thus you hear about people racing them forever without rebuilds, the aircraft guys seem to be very impressed with them (they run at max power for much longer periods than cars), etc.

 

yeah .. saw the first reply

but then nothing much to support it .. since the rotary is off and on the market that im sure lots of ppl are curious of its long term durability

if the only problem was seals and its fixed .. then cool .. predict nice results
though expecting this from the 8 .. i was amazed with the lemans articles when i read them

so is there anything else for/against the renesis?

 

The RX8 has been in the hands of the public for ~2.5 years. The RX7 has been around many more. Let's see what data we have to go by:
1. Mazda says it is a better, more reliable design than that of the RX7. Let's just say we believe that. Let's just say...
2. Many RX7 with over 150K miles and not problems.
3. Highest mileage RX8 on this forum? Not sure, but figuring over 50K easily.

Given #s 1 & 2 we can extrapolate that if RX8 = more reliable than RX7 and RX7 sample base has well ovefr 150K miles then RX8 stands a reasonable chance of being >=RX7 in reliability over miles.

Oh, and since this wasn't your question to start with...**** Off!

 

since you had to finish with **** off we can extrapolate .. that this wasnt an intelligent response ... thanks trhough .. like i said we needed more of those

 

I've seen several rotaries hit 200K plus miles. It's not that uncommon for a nonturbo to hit that. The key is in how well it's taken care of. I know someone will say that proves nothing but almost any engine can go a long time if it is taken care of. Some can't though. I had 2 separate Ford engines go south before 100K miles and they were both well maintained. By no means does that mean that every Ford engine will do that. The reason we see alot of blown up rotaries can be linked directly to the owners. Sure you'll find one every once in a while that just went south before it's time but more often than not when you see a blown turbo rotary, it is a modded one where the owner didn't know what he was doing. I can say with absolute certainty that there are FAR more turbo rotary owners out there that have no clue what they are doing than there are those that do. If properly taken care of there is almost no reason why the rotary or any other engine shouldn't live a long life.

 

actually, the type-s is the japanese (and possibly other markets?) designation for the 6-port hi-power model, which everywhere outside the NA market is only the MT (and in the NA market, its only the 2006 AT that gets the hi power engine).

 

it was slightly more popular in japan, continuing through 2002. no idea what sales numbers were like though.

 

Check out the Autos.MSN site. They have reliability ratings for the get III RX-7. They seem pretty good. The’93s got a yellow mark for having the old AC refrigerant. Other than that, it’s all green marks for all component categories including the (rotary) engine.

The ‘91s got dinged for having bad oil metering pumps, which I understand were causing engine failures at the time.

watz da best way to maintain rotary engine??

 

Simply by following the routine maintenance as listed in the owner's manual.

 

I've heard adding FI to a rotary is a good thing!

 

wat do u mean by FI

 

FI=Forced Induction=Turbocharger OR Supercharger

 

the owner's manual of rx-8 recomends to use 5w 20 engine oil,but they dont mention about synthetic or premium oil....which one shud I use for renisis..though im using 15w 50 synthetic oil....

 

This is a topic that I've had my interest in for a while and have done lots of research on my own...
I was actually looking for a used RX-7, 2nd or 3rd Gen, a while back on many search sites, and the most mileage w/o rebuild I saw was no more than about 170,000 miles.
I would like to hear about anyone with any generation Rotary engine with 300,000 miles or more, with NO REBUILD, like many Hondas and Toyotas that I've witnessed.

 

use 20w50 in the summer and something thinner in the winter. remember rotaries run hot N/A or turbo

 

the rotary can outlast piston engines. i've had my 85 GSL-SE rx-7 and before the engine rebuild the engine had 236k miles not Km. again 236,000 miles. and compression was still a healthy 105-108-106 on the front rotor and 108-110-120 on the rear. i just decided to rebuild it cause i want to create a rotary with more torque than horsepower. hello Super K03 turbo from neuspeed.... most piston engines will need rebuild or replacement at 120k or so just to keep the power and fuel efficency. but then in my town 85% of ppl dont take care of their cars. most have tranny probs and every one of them has a dent thats at least 1sq-ft. but honda engines will last just as long

 

my rx-8 runs only 4000km,when shud I change my spark plug??

 

all sounds good to me so far .. i have to agree the turbo mechanics often cause their cars to blow and its not only in the rotary family

 

Are you sure you read the owner's manual? It clearly states that the recommended time for spark plugs is during the 35k mile service.
