4cyl to a 6

How complicated is it to swap engines from a 4 banger to a v6. Would I need to install a new transmisson?

Here's basically what you would need:

-V6 engine
-ENTIRE wiring harness from the donor vehicle, including computer
-Motor mounts
-Matching transmission
-Matching transfercase (or adapt your NP231J to the new transmission)
-Axles with the correct gearing

Basically you're swapping the entire drivetrain. The stock axles would work, but you'd need to gear them properly, and the D35 isn't worth wasting money on unless stuff was given to you for free.

V6's are viable swaps, some of them make more HP and torque than V8's do... Some...

Not in stock form for less money though....I had a 400 horse 2.3 back in the day, but she didnt last very long before she imploded. And most of your v8's are gonna do better in mileage, be easier to find parts for, and we dont even have to discuss aftermarket support. There are some peppy v6's these days, but they cost more than my stroker motor.

Add to this ALOT of time, new exhaust, Driveshafts (unless you are VERY lucky), cooling system along with the hoses to connect it to the engine, Fuel delivery system, Engine mounting hardware including adapters, More time, fluids............

and alot of patience...
