1.8t into older I-5 cars (was RE: generic A4 questions)

So all this talk about the 1.8t makes me curious about why no one is
swapping them into the older cars.  Is the bolt pattern completely
incompatible?  Is it just too tall to fit under the hood on cars that
originally had the I-5?  The bolt pattern problem can be solved easily but
changing the motor to tilt isn't.
