The 3.7 liter V6 engine from the Liberty was also an option on the Wrangler. However, in order to replace the engine to a V6, replacement of the powertrain control module would be required to make this work. Different engine mounts, brackets, A/C and power steering lines, as well as electrical connectors may be required to make this work. Unless you are doing an engine swap for performance, I would recommend against doing this replacement considering all the work involved. If you can not find another four cylinder engine for your vehicle, unfortunately, it will likely cost much more to install the V6 and might be more beneficial to search for another vehicle

5.3 Engines are a great choice and offer the most budget friendly conversions due to the availability and cost. The 5.3 makes great power for a average built 4 door JK. You can pull a small trailer and have plenty of power for the highway.
However, of all the swaps out there, the 5.7 Hemi swap is going to be the easiest. Since the Hemi is a Mopar product (like Jeep), it goes in with the least amount of fuss versus lets say an LS swap. This is why it`s so common to see Hemi swaps in JKs, because it`s a very, very documented swap.
You can either swap another engine that`s designed to work in the car you have, or you can swap in one that`s totally different. As you might imagine, swapping in a completely new engine is way more difficult than putting in a manufacturer approved alternate engine.
The difficulty of performing a swap varies based on the combination of the auto body and the engine you are working with. Even the most straightforward swap, however, can be tricky. Each engine requires its own electronic system, and your transmission, fuel delivery, and steering may also need to be updated.

So, other ways to figure out if you have a JK, TJ, or YJ – as well as the vehicle year – are through the Vehicle Identification Number (VIN). Most insurance cards list this number and you can enter it on Jeep`s website here.
There are plenty of Jeep enthusiasts who say they`ve had success swapping vintage small-block Ford and Chevy V8s into their JLs. Listed below are some of the most popular engine swaps and how practical they are for the JL Wrangler.
The driving force behind every trek you take in the Wrangler is its engine – choose between four-, six-, or eight-cylinder engines, and gas, diesel, or the all-new plug-in hybrid 4xe powertrain.

The best three models for off-roading (in order) are the Willys, the Rubicon, and the newer Rubicon 392. If you`re looking for a good daily driver that is also off-road capable, the Willys is a great option. Hardcore off-roaders, on the other hand, will benefit most from the Rubicon and Rubicon 392 models.
Depending on the reason behind the swap, you can replace the old engine with an identical one that`s in better running condition or with one that offers better performance and reliability. Either way, engine swaps make a lot of sense for someone rebuilding their classic car.
It`s definitely possible to put a new engine in an older vehicle, but you`ll want to check that it`s compatible with components of the car like the transmission. If it works, replacing the engine will make your car more powerful and more reliable.
Swapping out a damaged engine with a lower mileage used engine (from a wreck for example) is risky and not advisable. Especially since some makes and models have engines that are known to have a high rate of engine rebuild history.
Another factor that heavily impacts the cost of an engine swap is whether you need a new transmission. You generally won`t need to replace the transmission, even when your engine has been totaled. If your old transmission can be salvaged, you`ll save yourself a lot of money!
The LEA is an engine produced by General Motors for a wide variety of compact and midsize vehicles. Displacing 2.4 liters in an inline-four configuration, the LEA is part of the Ecotec engine family. It features direct injection, variable valve timing, and is capable of running on E85 fuel.

Known internally as the TJ — following Jeep`s two-letter coding convention — the 1997-2006 Wrangler offers classic Jeep ability at an affordable price.
Compared to the YJ, the TJ`s frame was given a 100 percent increase in torsional stiffness. The frame was an additional 15 percent stiffer with an additional 8-inch lift. Even more important than that, the TJ used a four-corner quadra-coil suspension in lieu of the YJ`s leaf springs.
Each Jeep model, (with few exceptions) comes with a two-character abbreviation: JK – Wrangler 2007 – present. LJ – Wrangler Unlimited 2003 – 2006. TJ – Wrangler 1997 – 2006. YJ – Wrangler 1987 – 1995.
Overall, Edmunds recommends the Wrangler Rubicon. It is the most capable version when the going gets really tough, and it comes with every available engine and transmission.

Performing an LS swap, or any V-8 swap for that matter, can be a remedy for an underpowered Wrangler. We opted to replace the Pentastar 3.6-liter V-6 in our 2016 Jeep Wrangler Unlimited Rubicon with the all-aluminum LH8 5.3-liter LS engine found in the H3 Hummer.
