Yesterday I tried driving aggressively on a back road and missed the 4-5 transition and instead went to 3 and over-revved. Then I did it again missing 5 completely and just over-revved in neutral.
Learning MT is the pits.

You'll be comforted to know there is a rev limiter preventing over revving in neutral or by use of the gas pedal. You can only over rev by downshifting too early and letting the clutch all the way in.
You can damage the engine by overrevving it even with no load as maximum load on the conrods is reached at TDC on the exhaust stroke, when both valves are open and the piston reverses. Most conrod failure occurs then. Also, above a certain rpm the valves begin to float on their springs and contact between the piston face and the valve heads is possible, again most likely at TDC on the exhaust stroke.
Two things: never, ever over rev your engine and fortunately this particular engine will suffer no damage if you over rev it only a little bit, apparently, and don't ask me how I know this.
It seems very likely this engine is designed to accept a red line of over 8,000 rpm before it becomes a boat anchor. In fact, the easiest way Subaru could develop more power is by raising the redline. This is one of the few engines I have driven recently (other than a Porsche or Ferrari) that seems perfectly willing to pull through its reasonably high redline so there's more to be had above 7,400 rpm with a proper cam profile.
