Hmmm. He has a '93-'94 front bumper cover and a home-made airdam. Looks like the vinyl edging material you can get at Home Depot. Make some 90º brackets from the metal of your choice, bolt them to the bottom of bumper cover (after drilling the holes), them mount the air dam material to the brackets. Easy-peasy-japanesey. The bumper cover was also cut open above the existing slot and screen was riveted over it.

Another option is a splitter: a flat plate attached horizontally under the bumper extending both forward and rearward of the existing air dam. It limits the amount of air going under the car by forcing the air above the splitter lip to go over the car while simultaneously creating a low-pressure area under the engine, assisting the marginal radiator equipping all Sentras.

The air dam will do this to some extent but creates a larger low-pressure area with less differential pressure. For downforce purposes, they should be rougly equal but the splitter should work better for cooling.
