When I had my 97 PF, I upgraded to the Nisaan Motorsports 262 cams as outlined in the "project Pathfinder" - http://www.nissanforums.com/pathfinder/35288-project-pathfinder-3.html. I went with those ones vs. the ones from 4x4parts.com ( https://www.4x4parts.com/catalog/index.php?cPath=367_130 ) because the Nissan ones were supposed to have better low-end torque. I definitely noticed an improvement when I did it.

Now I have a 2005 PF and am looking to upgrade the cams on this rig. Will the 262s work with the 4.0L engine? The cams for this motor from 4x4 are quite a bit more. Any idea if the 4x4 ones give more upper end HP as opposed to lower end torque? I should add that I'm doing this to increase hauling capacity as I'm hauling a trailer with load that would be in the 5K-5.5K range. (edited to add: I did call the guys at 4x4parts and was told the increases would be in the 2800 - 3200 RPM range based on the dyno. Gains are about 15% HP gain and 13% torque).

Anyone upgraded their cams on the 2005-2008s? I'm wondering if I need to let the powertrain warranty run out first before I can do the mods?

Thanks for the info on the supercharger. However, it really only provides upper end gains, in the 4K - 6K RPM range. Since I'm wanting to improve the hauling capability, this doesn't assist me. Besides, I need more dough to do that.
