I am curious about what the average expected life span in miles(kilometers) is for a well cared for factory stock engine.

I may need to answer this question when asked by the insurance company when they asess the engine's value.

200k miles atleast.

Bought a '90 new in '90. A GTU NA. Original engine lasted 229,000 before rear rotor lost compression. Rebuilt went 90K before the body was destroyed.

Changed oil every 1,500 - 2,000, otherwise normal routine maintenance. In 315,000 miles it went thru 1 clutch and one driveshaft, and one rebuilt core. Nothing else major. Reasonably cared for RX7s are simply exceptional machines. As a testiment to my respect for the car, I bought another '90, a GXL when the first one died in 2002.

So far I like what I hear

Wow, dave lemon Said at mazda trix someone had one with like 380,000miles on the engine.

this is like asking how long you'll live.

Mine is at 162,000 and counting.

By design some engines are built to last, understressed and not set up to wring every once of available power.

Where as some are tweeked and tuned to a point where they may not be expected to survive much past the warranty! Got to wonder about the WRX STi @ 300hp!

I'm sure that most would agree that a 13bREW producing 500+ HP wouldn't last 200,000 miles

Sort of, what I need to know is more of a real world assesment of the life expectancy.

Saying that it should last 150,000 miles is much different then the statement, 'These engines have proven that a 200,000 mile service life is quite common'

I've got a 1990 GXL with a 102k on the clock. My clutch is starting to go (original clutch), but the rest seems to be doing pretty well.

I have a 91 convertible with 110000 and engine is solid as a rock. Noticed the beginning of an auto-tranny slip recently, more noticable when fluid is cold. Have to have it checked out. band slip i would guess.
