Can you fit a more modern VW engine (1.8T, 1.9 TDI) in a VW Corrado easily? Any major pitfalls/problems?

Theres been plenty of people that have done the VR6 in the G60, and its a pretty tried and true motor... You can find plenty of info on those conversions on the web. As far as the newer 1.8Ts and such, I'm sure it can be done, depending on your budget, it could be cost prohibitive. Lots of parts to interchange.
