i have put 23k miles on my motor since august, still runs great and sees 8k 5-8 times a day

I decided to rip apart the AE, and my vert had been sitting for like 5 months. Went out, and the vert started up on the first try. I was happy. Now I've been driving it for a week now, and it uses half as much gas as the AE too. Gotta love that!

thanks,

they lose power for the same reasons piston engines lose power. its either the compression is low, the exhaust is clogged, fuel filter? air filter? ignition? some of the details or different, but there not really that big of a difference between a piston and a rotary, when you are diagnosing something.

Not lookin' for a debate on piston vs. rotary, but I disagree. (I'm keepin' my 13B for now, until inspired otherwise.) I think they are alot different when it come to durability. (But I know you're right about the similarity of diagnosing problems) I have seen literally hundreds of piston engine vehicle with 200K+ on the original, never rebuilt engine. They still run strong. My dad's S-10 and my Ranger are 2 prime examples...over 215K on both, never rebuilt, still run strong. If U see a 200K+ rotary, chances are that it's been rebuilt once, twice, or even 3 times before. (or it runs like $#!^) He's right, they lose power over time. Simply said, they lose compression and have to be rebuilt. YES, piston engines lose it as well, but not near as bad...and NOT to the point that they need rebuilt every 75K. [/quote]

i didnt mean to even start that one, lol. i was just saying when a rotary or a piston motor fails its pretty much the same thing.

oh and since you started i know of several oil burning @40k miles camaros, and a couple 110k+ orignial engine fd's.

And even if rx-7's are known for having low reliability/durability, it doesnt exactly reflect on the wankel engine, but rather mazdas implementation.



Alot of the piston motors you will mention lasting xxx,xxx miles have recieved far more r&d time and money, if you were to take piston engines back to a level where mazdas 13B is in it's development, you would probably have something that throws rods on a regular basis.

yeah... rotaries can last. My friend had an 83 that he just sold. It was up to almost 198,000 miles. Its rediculious.
