Renault 2.0T 2006 - Turbo replacement

Renault 2006 2.0T has just been diagnosed with a turbo failure at the joint I'm told. Lots of white smoke when starting from cold, as the engine warms the smoke dies down but is still visible along with the odour.

Questions that need helping with please

Does the engine need to be removed to replace the turbo unit ?

Is it correct that it is Mitsubishi turbo fitted ?

Does anybody know or have a second / re-conditioned part ?

Many thanks
