You would have to first go through Immigration, then Customs, then you're exiting into the arrivals hall, in which case you'll have to head all the way back up the the departure hall, go through the nwa security check, then airport security, then you have to wait through exit immigration.

A lot of variables, I wouldn't risk it with 2hrs or less to do it, maybe others might, the flight might arrive on time, but take time to taxi to the gate, or you have a delayed arrival, or you can lose a lot of time either at entry immigration, the airport security lines, or waiting to get through exit immigration.
