engine swap.
not too long ago they did a build on an 07 wrangler 4dr and they dropped in with some fabrication a cummings 5.9L. I have an 08 4dr and was looking to swap the engine, but I was looking to go bigger to a 6.6L duramax but I want to know is the 402 cubic inches going to be too hard to fit? and would it be worth it in the long run because really it seems like I would be able to pull a lot of the same power and torque numbers from the 5.9L as to the 6.6L without having to deal with the weight. this is the start of a very big build for me and I am no mechanic but this is a passion and my dream ride.

Tip:

Walking the Crossing<br> When walking your water crossings its best to walk in the intended wheel tracks to find if there are any hidden rocks or potholes, as well as for checking the depth. Potholes at common crossings are often caused by previous 4x4 spinning their wheels after hitting a submerged rock. So if you find a pothole, check for submerged rocks. It's a good idea to place markers at these points so you can avoid them. Its been known for a vehicle attempting a relatively easy crossing to suck in water when a single pothole has caused the hood to momentarily dip below the water level, causing water to enter the air intake, resulting in hydro-lock and a damaged engine.
