Got all the parts for oil pressure gauge install, but the gauge.

Two choices, 0 - 80 psi or 0 - 100 psi...

What is the average and max oil pressure of a 451 Smart?

Which one do you suggest I get?

I doubt they have 100 psi, probably more like 40-60 at most

Oil pressure specification at operating temperature is .6 to 1.6 bar at idle and 2.5 to 4.3 bar at 3500 rpm. This assumes the proper specified oil.
