Carry a jug of cheap oil with you and slick the pavement you wish to lose traction on. Instant fix

The first time I read this, you hadn't mentioned the part about wanting to completely lose traction. It's nicknamed the 3.sl0w for a reason. I suggest this:

5.0 Swap

Your model has Cold Air Intake(CAI) already, and it has scavenging "headers" for more mid-range power, you could replace these with low-range headers, but you do lose mid-range.

Replacing mechanical rad fan with electric frees up a few "ponies" isn't much but isn't nothing either, also better MPG, so win-win, power and economy.

3.0l is a high RPM engine, it makes highest torque at 3,700rpms, a 4.0l has highest torque at 2,400rpm, so you do need to get the RPMs high and stay high to get any power from the 3.0l.
If you drive it like a low RPM engine, i.e. the 2.9l or 4.0l, it will drive like a slug

Breaking the tires loose is torque not horse power.

Swap some 5.13 gears into it, guarantee you will be able to break the tires loose with them

Not to be harsh, but by your basic question of how to increase power, swapping in a diesel is not something that is plausible.

Stick to a 5.0 if you are seriously thinking about an engine swap.

In 2002 Ranger 3.0l is listed as 146HP and 180ft/lb

1997 Explorer 5.0l is listed as 215HP with 245ft/lb torque

Torque is what you want.
Torque gets to going(0-60mph), horsepower keeps you going

This.

Not to mention the aftermarket for 5.0 parts and the engine's potential in general are exponentially greater than that of the 3.0
