isn't a remapped 20v about the same power as a standard R32? R32 must weigh a lot more as well.
No, A remaped 1.8T will sit around 190 - 210 depending on turbo type and general health of the engine.
To get up to the 250+ mark your going to need to start looking at a KO4 turbo upgrade and thats when your wallet really starts to get light.
As for "bad" things about a MK4 R32 . . . what have you heard? I've not heard a bad thing about them other than fuel consumption and what the hell do you expect from a 3.2 V6 . . ?
