Like it was said earlier, they just require maintence...
The motors WILL last if you take care of the car, I'm up to 115K stock motor/turbo.

Re: Do rx-7 have motor problems?
im about to jump on the rotary bandwagon and i would like to know if there is anyone in the 757 that is really good at tuning rotaries. i heard that one of the biggest threats to the engine besides improper cooling is detonation. i don't want to slap a turbo kit on the car and have some shop that doesn't know what they are doing blowing up my engine cause it went lean when they were tuning it! thanx.

one of the major issues with rotaries is intake manifold gasket leaks. they screw up your idle bad, hurt you gas mileage, and hinder performance. also you can only order them from a dealer and it will take like a week.

Re: Do rx-7 have motor problems?
First off, what car doesn't have engine problems?
RX7's have a nasty name for themselves due to the fact that they consume alot, and spit out a lot of bad emissions. They produce a lot of power with a low displacement, but consume/process at a much higher rate than a piston engine. So, being that they work so hard they do tend to get 'crappy' faster than a piston engine. Which, is why you have to baby RX7's, and other rotary engines.
Let me know if I'm wrong..
