Same motor.
The SC motors have lower compression than the NA ones. If you converted you'd be looking at an upgraded wiring harness, a different ECU, etc....it'd be cost prohibitive. If you want an SC truck, find one that's that way to begin with and you'll be money ahead.
The SCs are notorious for not lasting very long. The VG bottom end will go forever though. Keep up with the timing belt intervals.
And yes, it's the same slug that's in the '98Q, though the weight difference between the two trucks is negligible. The 2002+ Xterra has deeper 4.90 gearing compared to the 4.636 gearing found in the Q and in 2000-2001 Xterras, so that helps marginally. A 2002 -2004 can be awakened a bit by a CAI and by removing the secondary cats, provided your state doesn't do visual inspections. My secondary cats were removed and I still go through Arizona emissions testing just fine.
A 5 speed will have a lot more pep than an automatic. Nissan automatics redefine the word "slushbox"
