I have a JDM Hawkeye and it takes one hell of a beating - standard engine with just under 500bhp. Oh and it doesn't use a drop of oil! This appears to be a general Newage 2ltr thing though, rather than a JDM specific benefit.
The JDM Hatch and later JDM Saloon 2ltr engines are (iirc) stronger still (more meat on the cylinders from what I remember).
To be honest, I wouldn't worry about it. Life it too short to worry.
Drive it and enjoy it. May be try and pick up a forged short block and stick it in the garage for a rainy day.
All engines go pop at some point fella. If you are worried about such things, the Impreza is the wrong car for you.
Exactly how I feel about it, I have had bigger things in life to worry about this is just a lump of metal in the grand scheme of things....

The choice of 2.5 was based on meeting new emission laws in the US and Europe. The JDM market is not as restricted and they go with whats best .
I've never understood the context of that. There are plenty of other turbo charged 2ltrs still being produced that meet emission regs in the UK.
Yes, but probably a lot more R&D has gone into those engines compared with Subaru and the dinosaur that is the 2.5. And not many of those make 300bhp either.
My understanding is that the 2.5 was 'invented' for the US market, so that it would be able to run on the lower ron USA fuel as Subaru wanted to get a slice of the US market.

I think there are some elements of truth around that understanding.
