Good article, would love one of these if I had enough days when I could leave the house on my own.
Not sure I'd want a turbo on this, unless it was extremely well done with no lag. For a car that's all about feel, a turbo can be a pain in the @ss if boost comes on too quickly, it upsets the balance and makes carving a nice curve more difficult. My old WRX (2002) was interesting when you were trying to fool around with it; lots of low speed understeer and you couldn't use the go pedal to counter it, you'd just lunge forward wildly once the boost came on, still pushing away at the front end. If you wanted to enjoy the power in a curve you'd have to do some sort of Scandinavian flick to get it balanced right, not always practical. With practice it got more fun but I'd have rather had a smooth power curve to enjoy the handling.
