Could the wrong 3b rotor trash a motor?

Chad,
Sorry to hear about your engine and I hope you'll get the car back on the road.
My first thought is: You said you could check your rotor easily, so
did I miss the part where you told us what the heck you found????
My second though was: Did you in fact discover that your blown engine
had the wide rotor installed and you wish to contribute a data
point?? What he (SJM) has stated, sounds reasonable and believable to
me. Whether or not the specified rotor actually helps protect
against engine damage at high rpm/boost conditions, the extra cost
for an owner to acquire it is essentially pennies and thus not a
factor [except of course to those who already strive for ever-greater
short-term savings and convenience by doing things like never
changing engine oil, using Fram oil filters and running brake rotors
'til they disintegrate.] I doubt that you are one of those folks.
