What type/brand oil are were you using? Synthetic?
I have seen certain synthetics attack the green Mazda orings.
Then the gas pressure that floats the rotor in the center of the housing is lost.
Then the rotor bangs the side plates.
Check the condition of the rear rotors orings. They were next.
My guess,

Another theory from Bryan at BNR Turbo's is that the stock BOV spring got stuck open and the turbo's overspinned and failed starting the oil leak which eventually led to the low oil level causing the engine failure. This theory does seem to match the series of events that took place before I noticed the engine losing power which was the turbo's losing boost and I'd hear a wooshing noise when I tried to go into boost. The boost came back on after I hit high RPM and WOT which at that point is most likely when they overspan and started the oil leak. Again, this is just another theory.
Maybe, once he opens up the turbo's we'll know more of what happened.

I Have Seen That Before
Just looked at this post. I can't comment on the root cause in the turbo's, but the internal engine shots look to me like the poor engine was just starved for oil. My first engine in my race car came apart in almost the same way after I reversed the remote oil filter lines by mistake. The oil was trying to go through the filter backwards and the oil pressure was fine, but high. The engine ran well until it starved for oil and stuck.
I burned the irons in the same way and pounded the poop out of the rotors, just like you did.
I find it interesting that you had white smoke coming from under the hood. I don't know what that means other than there was a leakage that manifested itself with burning oil escaping under the hood.
So let this be a lesson kids, If your rotary is smoking like a pig and you are using oil, stop driving your car until you figure out the problem. A tow is cheaper than a rebuild. At the very least stop a bunch of times and feed oil to your car until you get to your destination. 2 things kill rotaries, low oil levels and high water temps.

Actually it was Joe's car that hit your car. I know because I'm the one that jumped in and grabbed the parking brake so it wouldn't hit your car again. Sorry to hear about the engine.

On another note, the car should be ready next week lol.

My thought is that the green o-ring in this picture seems to be compromised.
On one engine that we dismantled (that used Mobil One synthetic oil) the seals looked softened just like that. When the owner let off the throttle (high vacuum) it smoked badly.
Would you please check the other rotor o-rings for damage?
