Mazda rx's exhaust overheating?
Yes and no. Rotary exhaust is normally between 1800F and 2000F. Exhaust components that are not made of thick wall steel will not be able to withstand the heat cycles. Also if you are reading higher than normal EGT temperatures this can mean your engine is out of tune.
Why your rx7 smoke on high RPMs?
It's because rotary motors have an oil injection system. If they don't inject oil to lube the apex seals you motor will self destruct. Just keep an eye on your engine oil level because they are designed to use oil, also, if you plan to run a rotary hard put a pint of 2 cycle oil in your gas from time to time. You'd be doing yourself a favor.
If you have an 87 Rx7 you installed an aftermarked turbo is an o2 sensor really needed and why?
the short answer is yes
the stock one gives a little bit of information to your ecu and makes your car run a little better
The long answer is
YES if you get a wide band O2 sensor this makes sure you are less likely to blow your motor by having a rich or lean fuel mixture then you can get your boost controller and turn up the boost!... well until you run lean and that will be about 1 psi from the stock 6 psi... then you can get a fuel computer and bring it to around 9 psi... but then you will need something bigger then your stock 550's... so get two 720's and put them in lead (but not trailing...i think) and maybe go to 12 psi... and you can only do all of this safely if you get a wide band O2 sensor!
I am doing that to my rx7 at nv8.ca

PS: the stock O2 sensor is a narrow band to do tuning you need a wide band with a proper gauge.
