To get you started, I will give you the following item numbers to enquire about: 17190-8Y001 - Super Charger Set (supercharger assembly, pulley, and bypass actuator), [AUD$4818.00 (inc.

GST)] Then you need to add the injectors, intake manifold, intake pipework (top hose is worth around AUD$100), etc.
