If I am not wrong the Cayman does not have oil pressure and oil temp gauges. Does it display that info on the digital readouts?

You are correct, it does not have oil pressure/temp gauges, nor does it have a digital readout of temp or pressure; it just has a digital oil level meter (and I presume an idiot light for pressure/temp problems).

It may be possible to swap in a 997 cluster. It was an easy swap to put a 996 cluster into a 986, but I don't know if/how much harder it will be in the newer cars.

Attention aftermarket folks!
Opportunity knocking here!
2-gauge cluster add-on with proper sending units. Could be integrated onto the dash or the left A-pillar or some place visible and logical. If the car is equipped with the dash top timer from the PASM Sport, then a 3-gauge cluster that integrates the timer and looks factory original and fits in the same location...
This may be a ENZO. I didn't look.
