How can you compare the two? They are two totally different animals.
...by the way wasnt a corevette(i thought) built with a four rotor but scrapped because it was too powerful for the average joe?

Never heard of it.Also, I wasn't the one originally doing the comparing, I'm the one that said there are more factors.
Thanks for siding with me.
EDIT: found it. It was a 585 cubic inch engine making 420 hp....I don't think they scrapped it because it was too powerfull though...

I wasnt aiming that at you particularly, just the whole agrument in general. Its just like arguing over a v8 or a I4 nobody will win because they are built for different reasons to withstand differenty types of abuse ect.
I cant remember where I heard the four rotor thing..im probably wrong.
edit: I was right for once?

I found it, you were right, but they didn't make it because the sales were too good on the current vette. They were selling more vettes than they could make. -
neat-o

ok, not to kick a dead horse here, and, not to step on any toes, but. That engine, in a completely stock form, can make a little over 500 horsepower, now, open it up and port it, that's how u get a little over 1800. Of course it's not exactly THAT simple, but you get the idea, to do that you need to be a stud, and have a great standalone system. But the moral of the story is that a rotary is a natural born killer.
Now, do you wanna trade cars????

I question your statement on why the engine and tranny were replaced....I was the one who ordered both of them for your car and I know the history of your visit at the dealership
You that blonde dude that works there? That used to wash cars or something now you work in the service department? I am sure YOU ordered them.... Anyway I know why my parts went wrong, both my engine and tranny where reparable but Marty pushed for them to get replaced. Why would I have a reason to lie about why they where replace. If you do in fact work there, you would know that I drove the car there to get the engine replaced and I drove it there to get the new tranny also. The side seal went bad and was leaking coolant into combustion chamber, it was still drivable, the engine didn’t "blow up" nor did the tranny the ONE time I had it replaced. -

You just agreed with me. Lighter components (or less moving components, I.E. Less mass being moved) will be able to rev higher than a larger (more moving mass) engine with parts manufactured at the same quality level.All I said, is how high your engine revs does not reflect how well built your engine is. There are are different factors other than how high it revs that determine that!
It's a simple fact. It's not that in depth.
Also, his engine was DESINGED to spin that high. If it FAILS to do so, to me that isn't as hihg of quality as I would have expected. If my car failed when it spun to 6,000 rpms, I would be dissapointed too. The technology in that car simply isn't far enough along yet to have it be as reliable as a piston engine.
Also, what does lifting it out of the car have to do with anything?
As for the quality of the parts that go in my motor like Sean is questioning, the only problem with the engine (specifically the I-III series 13b engine and earlier) was the sealing, from the side seals to the apex seals, Felix Wankel states that he never got the sealing quite right on the engine. But now with the new Renesis engine they moved the exhaust port to the side of the rotor housing rather than having the apex seals pass over the exhaust port and getting worn out. The new Renesis looks to be a very promising engine. For example my car makes 255hp stock, the RX-8 makes what 238hp naturally aspirated, on the same displacement engine. They achieved that all by just adding intake and exhaust ports. Also the internal combustion engine was invented in the early 18th century, the rotary was invented in 1957. That’s what 150years? I think you see my point. Along with what Chuck said. Only time will tell where the Renesis stands for reliability, I think you will be eating your words.

yeah. but its 190 or so whp which is what matters. thats why mazda bought a lot of htem back. lack of horsepower

I don't disagree with you. However, the engine in YOUR car still is NOT as reliable as a piston engine, simply because of the reason's you said. It's nothing to do with how your engine is designed, it's the fact that technology has only gone so far on that engine. It's a small trade off for owning a car that is a work of art and will easily be remembered for ever. -

no you had said that it has not been designed very well.and the reason i said it only takes two people to lift a 13b out of a vehicle is because you said was heavy
I never said his engine was heavy. And isn't desinged as well as it could be, simply because it's sort of a "new" engine. -
how much have you looked into the rotary, because if you want to know more FACTS here is a site for ya www.rx7club.com im done arguing with you this isnt the thread for that

Whatever. I don't want to create any enemies. There isn't anything I have said that is faulse.Zac, nice car, you know I allready like it.

again, I would if I could...not my department.

heres my 2 cents as a rotary owner. is the 13b(t, re, rew, whatever) reliable? yes.. it works perfectly well as long as you keep up with the maintainence. just like any other engine you have to keep the oil changed, the coolant full, and you have to love your car. if you neglect it, it will shit on you. if you aren't paying attention and you let it overheat, it will fail to work very quickly. if you mod it without knowing what you are doing, and run it lean, it will shit itself. just like any other unique motor, it has it's quirks, and you have to be prepared to deal with them. you have to wring it out once and a while to keep the carbon buildup to a minimum. does the rotary motor last as long as some piston motors? no. but you should know this before you buy the car. they last about 100k or more for a turbo motor, 150k for a well kept na motor, and then they will probably need a rebuild, or replacement with another shortblock. take my car for example. the motor wasnt very well taken care of when i got it and it had sat for a while. i didnt expect it to last as long as it did, but it faithfully provided me with lots of fun and ran very well up until the point where something happend with a rear seal. im not sure if the seal is destroyed or if its just carbon locked, but whatever. i dont even really understand the debate here.. piston and rotary motors are completley different things. saying one is better than the other is like saying red is better than black or something. i like the rotary because it is mechanically very simple, easy as hell to work on, has a nice smooth powerband, and is fun to tear the piss out of. if you dont like them, dont buy one. although i recommend every car enthusiast have at least one rotary car, just cuz they are alot of fun.
