TimH Posted September 24, 2021 Does anybody know which engines are compatible swaps into a 2016 NV3500 (4.0L)? I don't see many of those exact engines around, but a lot of VQ40DE Frontiers, Pathfinders, etc. Quote Share this post Link to post Share on other sites
crusty Posted September 25, 2021 Frontier, Pathfinder, Xterra. Note that you need to keep your transmission, it appears to be a beefier unit than the small trucks. Also need to keep your harness and sensors. Those changed over the years. But the basic 4.0 engine is still the same. Side note that the early engines '05 - 09(?) had issues with timing chain guide wear. 1 radin2son reacted to this Quote Share this post Link to post Share on other sites
