You just need to add the solenoid control wires and program the DME for the engine with 996 code. It is actually quite simple.
The extra pump on the M97 is a vacuum pump. Porsche went with a vacuum pump for the brakes on the M97 supposedly for better braking in high altitude and track conditions. It might necessitate some change to vacuum line plumbing, but doesn't make much difference.
The other difference is no dipstick tube, but I think they just put a plug in the case where it was on the M96, so you just remove the plug and put in the dipstick tube.
