Hmm, I heard something about an engine that was covered under warranty, but I don't recall the tranny. I knew he went through a clutch, but don't recall anything about the whole trans going.
I'm just going by what his old GF told me. Warrenty or not, a stock engine to go at 59K is a bit ubsured. -
true, but all a rotary needs is to get hot one time. Like I said, keep them cool and they're as reliable as anything else.

Thats true with any engine. If ya baby it, it will last, but as soon as you lean on it a little, rotories simply don't hold up as well as conventional engines. -
Lets just clear the air, I have had the motor replaced once and the tranny replaced once also. The motor was replaced cuz of a faulty "side seal" it’s the seal that goes between the coolant chamber and the combustion chamber, it’s just like a head gasket. Marty (the rotary mechanic at Lunde) pushed to have the engine replaced cuz he just wanted to see a new motor in the car. Same deal with the tranny it didn’t necessarily need to be replaced but it was, cuz on the tranny the bearing on the output shaft in the tranny housing went out. That’s and ez fix, but he wanted to see the car get a new tranny, and it all was covered under warranty so why not, right? But Chuck is right you have to keep em cool or they will shit on you. If you let them overheat even once you are just askin for trouble. See that’s the problem with 3rd party information, even if she was my girlfriend she still don’t know shit about my car, just like if you don’t even own a FD. As for the turbos going out early, never herd of it.

The race motors sit at 15k and above for most of a race.

Was I wrong? -

What redline the engine can reach doesn't reflect how well an engine is made. -

If you know anything about engines you would know that in order for one to rev that high it has to be built to precision. I would like to see ur LT-1 rev to 9k at the track for a whole day with no problems, where my car can do it, to what? you say only 60k miles? I didnt come in here to get into a flame war with you Sean, i just came to clear the air. -

Electric motors spin to 70,000 + rpms just fine, does that mean both our engines are weak? I'm just saying there are different factors that play into reliability. Also, it's LT1, the LT-1 is a carburated 350 fom the 60's 70's. -

It means your engine design is inherently well balanced (as a result of thought out engineering). The problem with rotaries is they don't like to sit. Unlike piston engines, they do like to be revved, instead of being babied.

i agree needs more motor.

Or that your internal parts are smaller/lighter so you don't need to fork out big bucks on as high quality materials as an engine with larger/heavier internals.How high your engine revs does not directly reflect how well built your engine is.

ok look a rotary has 80% less moving parts than a conventional 4 cylinder which might not have anything to do with this argument, but since it has less parts, it is easier to balance wich makes it balanced more evenly than your v-8.quote from my automotive engines teacher. Also like any other motor they have problems and things brake or just get worn out. It isnt just from beating on it like you seem to make it sound.....oh and tell me how often have you seen a rotor get scored? so heavier components, yes, but mor expensive, no. oh ya it only takes two people to lift a rotary.... how many people does it take to lift yours?
