Default V6 swap

Just got a Pathfinder with the 3.0 liter V6 and I was wondering what was involved in swapping it into my hardbody that currently has the z24. I'm planning on using the harness from the Pathfinder but my biggest concern is the transmission. Does it bolt up to my crossmember? Will it bolt up to my current 5-speed transmission? Will it even work? Any advice would be awesome

In reality it would be easier and cheaper to sell your 4cyl truck and buy a V6 truck. You'll have to rewire everything, maybe build tranny and motor mounts, custom driveline and probably a lot more.

I don't want to say it can't be done but it will take a lot of work.

The swap will fit, but the 4 and 6 cylinder transmissions are different bolt patterns. I do not recall anyone ever saying they needed a crossmember when doing a Nissan 4 to 6 swap. It may be just the tail shaft mount that you need.

But the pathy frame and the d21 frames are different, so I really don’t know.

And you will need the entire wire harness and computer unless you do a standalone ECM which is very expensive. Another option is to buy the Weber carb conversion kit for the vg30i and then purchase the GM HEI one wire distributor made for the VG30i, then you won’t need an ECM. The downside is both of those combined cost almost a grand.
