I put 110 octane race fuel mixed with 90 ethanol and alcohol free in my stage 2 set up Mazda rx8. afraid I melted rotor or possibly warped housing due to heat. I was on the free way and the car shut off. it would crank. now everything is locked up.

I'm not sure what that fuel would have to do with it locking up. If anything it should have kept it from getting too hot.

I don't think you melted or warped anything.  If it turns over with the starter then it is not locked up.  For the first step would be to run a compression test on it.  I think a sensor or module failed.  ou may have tripped the fuel pump cut off switch to.
