When does the engine usually die on a Rx7 mine has 148k is mine near its death? how long can the cars keep going without having to rebuild etc

 

we've had a lot of threads on this. 200k is a good age before rebuilding it seems. Some have lasted longer, some have not lasted as long, but from what I've seen they seem to have a pretty long lifespan.

mine lost an apex seal at 150k, I thought that was about average. Maybe Im just unlucky.

 

Mine made it 178,000 but I had just bought it a few month prior and I am not sure how well the engine was taken care of before I got it. Had an 83 that lost one after only 90,000. It was a single owner before I had it but I got it off a car lot so who knows how long it had sat without being ran.

 

yeah, I guess I sould say that I bought the car a few months before the engine went, and it ran pretty rough before it died. I doubt it was taken care of (juding from the rest of the car)

 

148 is about middle age for a 1st-gen, assuming it hasn't been abused (overheated, run way out of tune, allowed to sit for long periods)

 

in my opinion if people have good knolege of the rotary and how it works. a well cared for rotary can prolly last 400K+ miles. but most people just drive the car. do oil changes when ever its convient for them. and never check the omp to see if its even operating correctly.

but i would say the average is 100-150k

 

The highest you really hear about is about 300k. I dunno about 400k, 200k old housings start to look pretty trashed.

 

One of mine has about 250 ( lost speedo). Leaks oil like a sieve from housing seals but runs strong.

mine has about 200k on it

 

My co worker has an 86.........470k and counting.......


Mazda should give out badges when we hit 100k......200k etc..........Like Volvo does.........

 

222,000 here, but have only had the car a little more than a week.

 

i'll be at 185000 by the end of this week, and it's still running good. i plan to rebuild it by the time i get to 200k or if it blows before then... hopefully it won't *knocks on wood*

 

110,000 here.. had 85k when I bought it, and still runs strong as hell.

 

My 79 went to 283,000 before I lost an apex seal on the rear rotor. Got a new rebuild in it now. Hope I get at least half as many miles out of it.

 

Yesterday I bought an 85SE with 148k (I now have 5 rotaries) and tomorrow I take it to my mechanic to check it out and change ALL the fluids. He doesn't charge too much (about $200, as I recall, and I pay cash so he can report it at his discretion). I do this to any car I buy used (last month the used 74 REPU got The Treatment and the mechanic showed me the filthy oil patches from the diff, trans, engine, clutch, etc. ).

With conservative driving, good fluids, and either MMO or 2cycle added to the gas (4 oz. per tank), these things should run a long time.

what is this conservative driving you speak of?

 

*looks in the dictionary*

conservative: redlining your rotary at least once a week, and making sure all fluids are staying in the motor.

 

50,000 miles here and had ~10 engines ,5 tranies,3 radiators,2 diffs,4 wheel bearings, 5 stereos, 2 brake master,4 brake calipers, 4 clutch slave, 5 clutch master,
i can go on & on & on.

 

yo goofy, do your replace parts just for the fun of it?J/K Thats a lot though

 

Are you serious? On the origional motor?

 

I have 186,950 on my se and I think I can make it to 200k.

 

mine lasted about 98,000 miles but is because i whet crazy and put a turbo, weber on the stock SE engine. that wasnt smart at all but i had a hell of fun with it, ohh well i hope my new engine last at lease 50k

 

Bottom line is if you keep oil and antifreeze in 'em these things are almost bulletproof.

I don't know much about the turbos, but it seems the newer the model, the shorter the engine lifespan.

110,000 and still running so strong I've never even bothered to figure out how to use my factory compression tester
