The turbo can be installed on the manifold while on the vehicle, it's not easy, but can be done. One tip for reinstalling the downpipe to the mounted turbo, replace the studs with the latest version. At least one stud is shorter making a bit easier.

This will add cost to the job, because the gasket and probably manifold studs & nuts will need replacing, but it's not a bad idea to remove the manifold for inspection. Manifold cracks are possible. Installing the turbo on the manifold and bolting both to the head as a unit allows use of a torque wrench on the hard to reach fasteners and overall the installation is a bit less bothersome. The studs may need replacing because the early model manifold nuts have a tendency to seize on the studs. Take a close look at the turbo donut also, if it's deteriorated, replace it too.

New nut on the right.


Manifold crack.


Have a good look at your downpipe for cracks also.
