VW NUT!
I believe 2000-2003 1.8t 150 hp vr6 180 hp / 2004-2005 1.8t 180 hp. 2003 337 editions were also 1.8t 180 hp
Negative.
I had a 2002 GTI 1.8T and it had 180hp stock.
I know for sure in that. AWP was the 180hp and started for the 2002 model year. You can even find this info on APRs website under MkIVs.
AWD - 2000 model year on golf/jetta/gti
AWW - 2001 model year on golf/jetta/gti/wolfsburg
AWP - 2002 model year on golf/jetta/gti/337(yes its the same engine)
As far as the VR6, I'm pretty sure they increased the VR6 HP the same time as the 1.8t because they would have had the same HP if they hadn't.
