From same article:
This engine features a reinforced crankshaft with larger main bearings and new pistons with a lower 9.5:1 compression ratio. This allows the engine to take more boost pressure from a larger turbocharger, which blows compressed air through a reworked intake tract.

The lower compression and completely different turbo will require a unique tune.
