That really depends on what upgrades you are doing, but if you are upgrading the motor with quality parts, the motor shouldn't blow. You're more likely to drop the tranny or the rear end. You should try to upgrade things in steps, so you know your whole system can handle it.

With a mild street port and header as well as a high-flow air-filter you could see anywhere from 315 to 350 horses. Depending on how deep your pockets are, the sky is the limit. I Have seen rotaries cranking 600 horse street legal, and more on the strip. As for blowing one up, technically all you can do is crack an apex seal which is fairly uncommon in a stock engine provided you keep up with your regular maintenance. The "Very Minor" downfall of these engines is that they are designed to burn a small amount of oil to keep the rotors well lubed, therefore if you don't check your oil regularly you could run out causing your seals to fail thus loosing compression. NEVER Run Synthetic Oil!!! With the rotary engine there is not even a quarter of the amount of moving parts as a standard internal combustion engine so a catastrophic engine failure is not likely in any situation.

The mazda rx-8 has a redline of 9000rpm. but it does also have a rev limiter. I work with mazdas and i highly doubt theres anything out there short of pure stupidity that would cause you to blow the rotary engine. just make sure that you keep up with the oil, by design the RENESIS 2 rotor rotary engine consumes oil while running. dont use synthetic! use the suggested weight oil in your manual and check the guage and fluid level often.

The stock seals can handle a lot of abuse. Many higher powered rotaries still use the stock seals even over aftermarket seals. You're likely to see the stock clutch fail long before the engine. And you can run synthetic oil, such as on the older RX7, but you have to disable the MOP and run pre-mix. Probably not something you want to do, just want to clarify misinformation.

I've used my thumbs in the other comments..
But one thing... the oil gauge is a dummy... DO NOT assume all is fine because it doesnt move..
It does have a rev limiter, but I have shot mine higher than 9500 by downshifting instead of upshifting... wow what a roar!
Check the oil regularly, upgrade with quality parts, by a rotary tech, someone used to working on these engines.
And stay away from synthetic. :)

Well the engine only has 3 moving parts as aposed to the regular 40 ish in a piston engine. A good ECU and a good mechanic and your set for whatever yo can afford.

A stock mazda can handle everything you give it, so long all of your maintenance is up to date, and I'd recommend running synthetic oil if you intend on sustaining redline rpm's.

Great question !!! Now blow the engine and report back.
