Does the 1998 Porsche 911 Carrera 4/2 need premium gas?

Every gas trim of this model takes premium.

Trim (engine / transmission)FuelMPGFuel/yr
3.6L 6-cyl, 6-spd manual, RWDPREMIUM18$4,300
3.6L 6-cyl, Automatic 4-spd, RWDPREMIUM17$4,550

The EPA records the fuel each version was tested on. Whether premium is strictly required or just recommended is an owner's-manual detail the EPA dataset doesn't include — so we don't guess it.
