Your dealer is full of it!!!!
You do not have to take the motor out but it is tricky and one could
use an extra joint between the elbow and wrist.
I have never heard of a cracked turbo unless there has been a major internal
faliure. Make sure you check for any loose connections or blown O-rings on the pressure side as you remove parts.
Start by taking the brace between the strut towers off.
Remove the plastic pressure pipe from the top of the engine, there is a screw
under the "Twin charged" emblem.
remove the low pressure plastic pipe.
Remove heat shield to expose the Turbo.
Remove the clamps that secures the aluminum pipes to the Turbo.
Remove the three nuts securing the exhaust 90 degree elbow from the turbo
and tie the pipe to the other one.
Drain the antifreeze completely into a container, preferrably with a lid
(animals love that stuff and it WILL kill them).
Loosen connections for coolant pipes from the turbo, dont loose the copper gaskets .
Loosen the Oil pressure pipe. Loosen the oil return pipe from under the turbo,
(This is where the extra joint would have come in handy).
Remember to have a new gasket set for the oil return line.
Finally loosen the four nuts for the turbo to the manifold.
The turbo is now loose and can be removed.
Make sure to put some oil on all the nuts that see heat before loosening them, this due to that the studs have a tendency to back out of the manifold and the Turbo and messing the threads up.
The above descripition is to the best of my ability, not having the car in front of me and being about six months since i actually did the swap.
One more thing, make sure to have some band aid handy, you ARE going to get some scratches and nicks out of this one, but Hey, its worth it by the money you save.
