Its fragile because someone miss-shifted and went from 5th to second at a track day?

Such miss-shifts are for sure not a good thing, but certainly they are not that un-common in a MT car. The specific car's ECU log showed that it didn't even hit the rev-limiter, because the driver was quick enough to depress the clutch. In general, we could say that he had bad luck. If such cases start to grow and appear more and more often, then ...

That's why they used a Subaru engine in their "proper" sports car...

A mechanical overrev still happened and engine damage occurred because of it, not because the engine was fragile....

Especially since it sounded like he did a few more laps after the misshift occured...and the engine didnt fail until he took it to the track the next day.

My post was a bit tongue in cheek. No one can build a car that will survive a driver error like downshifting 3 gears instead of one. Well, that is, unless they eliminate manual transmission which they are well on the way to doing in most performance applications.

There was nothing really wrong with the 2ZZ if driven, prepared and maintained properly either.

No digital record of a mechanical over rev = there was no mechanical over rev, the sensors would absolutely register it.

Doesn't change the fact that the user shocked the drivetrain which caused damage to the valvetrain.
