Just passed 180,000 miles on my original engine going to work today, I'm planning to do a "planned" overhaul, i.e. hope it doesn't crap out on me before I'm on vacation for a week. Question is, should I plan on it in Jun (it'll have about 188,000 on it then) or my Sept vac (192,000)? Or beyond? I know a bunch of you guys have been "in this boat" before, when did you rebuild yours, or when did it crap out on you? She's still running good, 90+ psi both rotors, oil changes, etc...Plan on going with the rotary aviation rebuil kit and all new housings, if it'll last long enough to stockpile the parts!l

 

Go for the record! If there are no problems just keep giving it gas and changing the oil.

 

Ha,ha, I would LOVE to do that, but since I drive 50 miles to work each day on a dark, lonely highway (coming home), I would rather not take the chance

 

what is the record on mileage on an orig engine?

 

You got a Z06? how does it compare to the rx? you know, handling, enjoyable driving,etc...

 

I've "heard" of someone with 326,000 or so on his...That's crazy...

 

I must ask, why not just keep driving it until it gets a little weak? Mine, '89 TII, started acting up at 157,000. Drove fine with no problems until heavy boost in 3rd. Installed a Mazda remanufactured.
My everyday car is a Grand Cherokee with 213,000 miles. I'm just going to keep drivin' it. My wife's Grand Cherokee with 80,000 miles has had more problems than mine!
If you're really concerned about reliability, just pull and "rebuild" at your convenience.

 

what is the generally regarded compression point that it feels "a little weak"?

 

When to change engine?

when it goes BOOM??

 

just before it goes BOOM would be ideal...lol

 

I'd say around 85PSI. The main ingredient, I would say, is that both rotors are within 10 lbs of one another.

 

hey turbonut- you had any problems with that Mazda reman?
