there's two kinds of over rev, only one of which the car can control

the first is fuel based over rev

the other is a mechanical over rev which can be achieved through poor downshifting

Bingo. Hitting the rev limiter is no problem-the limiter is there to PREVENT over speeding the engine.

A mis-shift is the scary stuff because there is nothing to prevent an over speed condition and the pistons can actually hit valves in extreme cases. This is what would worry me.

My brother has a 94 Civic he drove for 12 years and he used to hold it on the rev limiter just for the heck of it. Now it is strictly a race vehicle and is still seeing the rev limiter! No problems. I wouldn't do it for sport, but hitting the rev limiter is no big deal. Overspeeding the engine is another story!

I was in first gear, there was no downshifting. The rev limiter failed.

Since you were going from 1st to second, the acceleration momentum could have kept it revving up. Did you notice a drop in acceleration right before you shifted? Im not sure if the limiter cuts fuel, spark or both, but it may have just kicked in. Or was it down hill at all? These little motors can take quite a beating and be fine.
