I dunno, looks like the platform is similar to Xterra/Frontier and Pathfinder before they turned it into a minivan. little bit longer wheelbase than the xterra but same as 2nd gen pathfinder (112" vs 106") with 5 link and coil springs in the rear instead of leafs or independent rear of the pathfinder. front suspension looks identical so titan swap
. 2.5l motor looks similar to the 2.5 that came in the base model frontiers, but probably updated a bit.
Shorten up the frame, ditch the 3rd row and put in the new 3.8 and you have a pretty solid vehicle.
