I agree, the VR6 lump is very heavy and ,unless special attention is paid to the chassis upgrade, will make the car very skittish. For the same money a 1.8t can be fitted which will be a lot more driveable, more tuning potential and a lot lighter. Having said that a VR6 driven mk1 would be awesome. As for the dash, it'll be a lot of work to get the mk3 dash in the mk1. Its a lot of work for an uninspiring dashboard, why not try the audi tt dash's?
