Any modern cluster uses CAN bus. Where in older cars either a mechanical ignition system or an ECU provided(usually analog) signals directly to the gauges, most CAN systems use a centralised computer that receives data from sensors and components around the car, and sends a data packet to the cluster where it is translated to lights and gauge readings.
In a modern car, when you turn on, for example, your headlights, the button you push is read by a controller. The controller sends a message to the main computer, which in turn sends a message to the appropriate light controllers to turn on the lights.
This sort of system is very complex, and as a result very difficult to emulate.
The biggest problem is the lack of standardisation. Every manufacturer uses different instructions, which can vary across brands, models and revisions. This is not something you can find in an owners manual. The relevant datasheet would be very hard to come by.
Unless you have friends at Porsche that can legally provide you with that data(which would likely be considered a trade secret), no piece of hardware but the exact car it was designed for will support your cluster as is.
If you have money to burn and the appropriate skillset, you could try to remove the electronics from the cluster and to drive the aircores/stepper motors with a separate controller.
This still leaves the issue of interfacing to a revburner, but that's a minor issue compared to the rest.
