That is one of the coolest things I've seen in my entire life.
I've been wondering - little here and there - if it would be at all possible to fit a 1.8L Impreza engine (with AWD) into a Justy. There's a surprising amount of room in there. It might require relocating the radiator, but...
Not that I'll ever get around to doing it. But what an autocross machine it'd be.
