And a 1.8T - I'm talking about a 20V Turbo, as fitted to Passats, MK4 GTIs, Leon Cupra Rs etc, - will do between 180-225 out of the box, and more if you've got a bit of cash to spend. And it'll have a hell of a lot more torque than any Mi16.
There's not a huge difference in weight. The interweb says a 205 GTI weighs
875 kilos and a MK2 Golf weighs 907 Kg. The weights of stripped 205s and Golfs differ by about 50 kilos. That said, I've seen about 50 different kerb weight figures for the MK2 in my time.
