Jeep Wrangler V8 Conversion Cost

Swap your Jeep’s engine for the ultimate power 

Chrysler has still not blessed the burly Jeep Wrangler with a V8 engine. Although it is common sense to expect the best possible power from the esteemed Wrangler, the parent company hasn’t really cared enough. But Jeep enthusiasts all over have been quick in swapping the engines of their Jeeps with the ultimate powerhouse. 

JK and JL Wrangler especially endorse the V8 swaps because of their ability to surpass the levels of power you generally expect. While you can definitely attempt to complete this conversion on your own, getting help from a proper mechanic will save you some time and effort. Your Jeep Wrangler V8 conversion cost could range from $2500 to $4000. 

Many Ford Windsors, GM LS-series, and Chevy small blocks have found their working fields in the heart of your beloved Wrangler. The exceptional V8 engine brings along all the capabilities the original Jeep engine lacks. This swap will not only make your Jeep great off the road, but it will also ascertain its absolute best performance while traversing the paved roads like a gentleman. 

Consider the expenses involved in the project 

It is important to understand that a V8 swap is not an inexpensive option. While it is the best way to elevate the power levels of your beloved Wrangler, it also involves a considerable amount of money. Also, this process does not get completed in some time. Although the difficulty level is not beyond reach, you must be ready to put in ample time, energy, and money to get the best results.

Most of your money will be spent on getting the right engine along with all the necessary tools and equipment to best complete this job. You can definitely save some amount by sourcing the engine and the equipment from the junkyard. Also, consider the fuel efficiency that will accompany the enormous boost in power rendered by a V8 engine. 

If you get the conversion done through a mechanic, the cost will definitely be higher. You’ll save ample money by completing the conversion yourself. Although, you need to be thoroughly aware of the various engine parts and possess adequate mechanical skill. 

You’ll surely be enthralled by the level of expenses this conversion demands. But a Jeep engine swap is a very great idea and this level of power could never be attained on a typical V6 engine. So if you desire exceptional power in your Jeep Wrangler, there is really no other way to do this. 

V8 swaps are becoming increasingly popular 

Because Chrysler still hasn’t hinted at the production of a V8 engine, the lovers of absolute power are only left with the option of a swap. It is speculated that Chrysler hasn’t yet upgraded the Jeep’s engine because it would increase their expense in taxes. A factory V8 conversion would increase the size of the engine and may also alter the fuel and emission regulations fixed for the Wrangler. 

It is also notable that this conversion would alter the power-to-weight ratio of the Wrangler. The Jeep’s engine is extremely powerful as compared to most other cars. But the taste of absolute power is only achievable with a V8 swap. It is no surprise that so many people choose to go for these conversions despite the high expenses involved.

LS swaps are more in demand than Hemis

Note that LS engines are generally preferred over Hemis. This is because the valvetrains of Hemis make them relatively less reliable. LS conversion is also less expensive than a Hemi. However powerful Chrysler’s engines may be, the obstacles in the current Hemi models prevent them from being absolutely dependable. Nobody wants to upgrade to new problems. Although LS comes with its own set of issues, they aren’t as prominent as Hemis. 

Hemis severely lag behind in reliability. These are not durable enough to serve you for a long time. The valvetrains of Hemis may be unreliable and faulty but they are definitely correctable. However, no Jeep owner would like to indulge in new problem-solving. So LS swaps are considerably more popular. 

Although, you can also opt for a crate engine if you are looking for something else. This would save you the $1000 that you would otherwise spend on the LS swap. No matter what you do. Be assured that a Hemi swap should not be one of your options. This new trend of swapping engines has greatly improved the performance, power level, and dependability of Jeep Wranglers. 

Consider the benefits of a V8 swap

Jeep Wrangler engines are thoroughly powerful, but they stand nowhere in comparison to the V8 engines. The incredible power performance of V8 engines is also complemented by their excellent fuel efficiency. Rest assured that you will save ample fuel with this conversion. The power production of your original V6 engine will seem to lag far behind. 

A V8 engine swap will also serve you immense benefits if you aim to indulge in more aftermarket modifications. If you shift to bigger wheels or enlarge your differentials and bumpers, know that the power-to-weight ratio of your vehicle is bound to be disturbed. You must consider the amount of stress the extra addition of weight poses on the engine. This balance is adequately attained by a V8 engine. 

A V6 engine could never accomplish this much integrity in balance while delivering such robust power. This is also an important reason behind so many Jeep owners inching for an upgrade. The dependable V8 makes it possible to carry all your additional accessories with grace. You can definitely boost this scenario by adding a programmer and lowering your gears. But nothing will make your Jeep soar like a quality V8 conversion. 

You can save ample money by completing the swap on your own

If you think you have the required technical expertise, reliable mechanical skills, and guiding knowledge, you can complete the conversion on your own and save yourself about a thousand dollars. The modification process will certainly be made easier by the comprehensive kits that have recently started appearing. 

You’ll also need some aftermarket support to adequately manage your newly modified engine. However, this conversion is definitely possible if you are confident in your abilities.
