This gauge would be perfect I think, although they don't list Nissan as a compatible vehicle. I'm not sure why it wouldn't work thought...
These are all the things it can pull from the OBD2 port. The two red lights can be programed to go off when a number from one of the options selected below reaches a certain point, sorta like an alarm. Its a pretty cool gauge but It does cost some bank. There is even one or two ports on the back so you can install your own custom sensor.

To bad you can't get it in orange to match the rest of the car.
