Yes Polygon is very right- the seals in the FD are more reliable- but they still aren't reliable to the point where you can place faith in them


Also my experience with Rotaries is that they have a very weak top end- this is just my experience at the wheel of a semi-stuffed 20B Cosmo and a perfectly fine 13B FC RX7.


Polygon- You have pretty much shown how handlng is a subjective matter- I perfer the Supras handling methods- you perfer the Vipers Torquier handling and gruntier power- different strokes for different folks they say

Those are the facts. The 13B has a few engineering flaws. That is not my opinion, that is the way it is. I can understand why you don't believe me since you own one. There is a reason that they made the Renesis engine and changed a lot about it. Mazda ate too much in repair bills fixing people's 13Bs under warranty that is why Ford management took quite a bit if convincing to let them make the new RX-8.

Yep Jim, you hit it right on the head. Hell I would love to won a Supra, in fact I plan to have both a Supra and a Viper in my car collection someday. . . . . . someday. . . . . . .

it's not the 13b that has the engineering flaws. there were some flaws with the cooling system, and a few other things when it was introduced in '93, but i don't think you can attribute any flaws to the engineering of the 13b. most of the trouble with owning an rx-7, and the reason they have a tainted reputation, is lack of support from the dealerships. since they were only made for the us '93-'95, by now, it would be obvious that most mechanics are not too familiar with such a different kind of engine. a few years ago was the worst times. if you needed engine work done and you took it to mazda, they'd fix the problem temporarily, but it would just need service again in like a year because of the poor jobs most of the dealerships did. i've heard of stories where the dealership will put their least experienced tech on the job of an rx-7 just because the more experienced one's refuse to work on it (because they had no clue what they were doing). that's why mazda "ate too much in repair bills." and the way i see it, ford probably introduced the rx-8 as an n/a so as to simplify maintenance for mazda mechanics, which was a good move. then after a while, they will be able to do turbos again when the market is right. yes i do have one, so i may be a bit biased, but also i know more about my car and it's history than those who have never owned a rotary. all i want to do is clear up misconceptions about the car that people may have. i just get upset when people make opinions based on information just because it's "common knowledge" rather than looking deeper into the subject for their own conclusions.

Look pal, I don't think you know how to read. The 13B has bad port overlap. This allows exhaust gasses to be in the combustion chamber. This causes the loss of power, this causes the bad emissions, and this causes the overheating issue. You can bet you pink slip that has to do with the apex seal problems as well. That is a design flaw in the engine which they have fixed with the Renesis.

That is just the way it is, sorry. I understand how you feel since you own one, but those are the facts, deal with it.

damn, take it easy. no reason to get rude. i got all that info the first time. ok, so there is room for improvement on the engine but it is not the disaster you make it out to be. that's all i'm trying to say. if it's such a bad problem, then why are n/a rotaries capable of 200,000 + miles?

Rotaries are capable of 200,000 miles WITHOUT any form of trashing- ie. Driven like a grandma car- If you do the slightest thing to overheat a 13B then you are screwed simple as that. I've seen it happen thousands of times before

that goes without saying. ofcourse overheating the car is going to mess it up. why ya gotta critique everything?

Viper...dont have to modify it as much as the others...is more reliable than the RX7...and if you decide to mod it...it will go like SIN and wax all
