With a '99 you've got the old 2 valve engine, rated at ~170HP, which IMO is clearly not enough for a 4300 pound 4WD truck. I mean that's 5000 pounds with 2 people and vacation luggage. The 240HP rated 4 valve VQ35DE (although my butt dyno says more like 215-220) while not a hot rod, is fully adequate. Later variations of that engine have more power and 4.0 displacement too although I'm not sure how much work a swap would be. So, you've got that problem/option. The 2nd gen/R50 platform ran for 10 years so there is quite a bit of stuff available, although not quite all of it applies to the QX4. Mostly, but not all. I'm not that into them to really know, but I'm not aware of any custom body parts, but there are aftermarket push bars/winches, lift kits etc more in fitting with a 4WD truck.
