I know there was a 4Cyl, and then a 3.3Ltr and a 3.6Ltr V6 engine. That doesn't sound right. The Pathfinders were the first to come out with the XE and SE editions. I believe the dealer told me the SE stood for Sport Edition. These had bigger rims/wheels, roof rack, side rails, factory brush guard, rear mounted spare tire, etc.

I had a '93 XE-V6 model, but I had a rear mounted spare where most were stored in the cargo area, no roof rack and I added after market brush guard and step rails/nerf bars and rear tail-light guards.
