Just saw this in my YouTube feed from Driving Sports TV; a pretty good interview with a Blobeye Impreza owner who's made modifications to his car to make it sort of like a naturally aspirated WRX. Worth a watch!

I've thought to myself for a while that it's be cool if Subaru made a naturally aspirated WRX today and now I have my answer: just build one! Although, aftermarket support for the current gen Impreza is pretty slim.
