Why it won’t work in a ’99-’04 Grand Cherokee WJ

As the 2004 model year progressed, rumors kept surfacing with some sources saying that Jeep was in fact testing WJs with the 5.7 Hemi engine. What they didn’t know at the time was that some of these test «mules» were actually 2005 WK Grand Cherokees, but with modified front sheet metal from 2004 models. This was one of the reasons that some industry sources were saying early on that the front end of the WK was going to look nearly identical to the WJ. But early WK mock-ups and test mules used some of the existing sheet metal until Jeep was ready to stamp out new parts with the WK specs. The hood and fenders had to be 4″ longer in order to accommodate the larger Hemi engine.

A couple of years ago, not long after the new 5.7 Hemi was introduced, the engine was made available in «crate» form, as is done with most factory engines. The engines, we are told, were swapped into some older vehicles, but no one had attempted to try one in a modern production vehicle until a Montana company modified a Wrangler in 2002.

At the Fall 2002 SEMA show in Las Vegas, show attendees were treated to a special surprise — a 2002 Jeep Wrangler with a 5.7L Hemi engine under the hood. Featuring 355 horsepower and 375 lb/ft of torque one could imagine how fast this Wrangler would get you wherever you wanted to go. The company that performed the modification was American Expedition Vehicles, the first company to retrofit the new 5.7L Hemi into a modern production vehicle. AEV is a Montana based company specializing in award-winning custom Jeep modifications and has received three DaimlerChrysler Design Excellence awards since 1998. AEV vehicles have been featured at Camp Jeep for the past six years.

Fitting and configuring a Hemi into a Wrangler presented a few challenges. The Hemi engines are designed with the NGC Bus protocol while the Wrangler featured JTEC. A custom computer had to be built to emulate some of the Dodge functions to make everything work correctly. Fortunately, the narrow/tall Hemi engine was fit into the engine compartment with very few body alterations, although very snugly. It is actually easier to fit the 5.7 Hemi engine into the Wrangler than a 4.7 which is lower and wider. All other issues were overcome, with all of the factory functions and diagnostics retained.

The Hemi and the Grand Cherokee WJ

The question is, if a 5.7 Hemi engine can be swapped into a Wrangler, a «smaller» vehicle, why can’t it be done in a WJ Grand Cherokee? As soon as Hemi crate engines became available, WJ owners were inquiring about the possibilities of buying one and having it swapped into their Jeeps. When it became apparent that Jeep was not going to build a Hemi WJ version during the last model year, even more owners were anxious to try and have this done.

In early 2003 we contacted one of the engineers at Jeep and inquired about the possibility of swapping a 5.7 crate engine into a WJ. He told us that it would be «major surgery», if at all even possible. First, the entire engine compartment would have to be repackaged. The ABS system and brake lines would all have to be moved as well as all of the engine hoses and wiring. Since the Hemi uses an electronic throttle («drive by wire») the Dodge PCM would have to be modified, or more likely, an aftermarket computer would have to be built and programmed for a lot of vehicle functions as was done with the Wrangler Hemi. The complex engine wiring would be another challenge as Dodge harnesses would have to be incorporated and modified.

And that’s just for starters. Since the 4.7 engine is low and wide, the taller and narrower Hemi engine would be a difficult fit. The suspension would have to be lifted and other engine bay modifications performed as well. According to American Expedition Vehicles, the conversion of the JTEC to the NGC type controller would be much more complex for a WJ than what was required for the Wrangler. The Wrangler has a lot less feature and programming requirements.

Finally, there is the issue of emissions (and CARB certification for some States), gauges, air conditioning, cruise control and so on. Did we mention cost yet? The Wrangler Hemi conversions costs around $18,000 (less some credit for existing engine & parts). A WJ conversion would probably run well over $20,000.

The bottom line, it appears, is that it is not only economically not worth the swap, but perhaps physically and electronically just about impossible. The best advice for WJ 4.7 owners wanting a lot more power would be to look into a Kenne Bell supercharger, at under $5,000 the cost is about 1/5th of a what Hemi swap would be (if it were even possible). For those not wanting the hassles of keeping a supercharged engine «in tune», and who gotta have a Hemi in their Grand Cherokee are left with one choice — to buy a new 2005 WK with the Hemi option. No fuss, no muss, but it will set you back around $38,000 (MSRP). If budget is a concern, used Hemi Grand Cherokees will probably be selling for around $20,000-$24,000 in about three years.

Jeep Grand Cherokee 5.7 Hemi 0-60 (How Quick)

The Jeep Grand Cherokee 5.7 HEMI is a mid-sized SUV from Jeep with a potent engine under the hood that packs some nice punch. If you are thinking to yourself, I don’t want just any car, I want the fastest possible 0-60 time, then this might be right up your alley. So let’s get into it

What is the 5.7 hemi engine?

The 5.7L Hemi engine is a V-type 8 cylinder engine. The 5.7L Hemi engine is commonly referred to as the 345 Hemi due to the fact that it has 345 cubic inches of displacement. This engine was first introduced in 2003 on Dodge trucks and SUVs. The 5.7L Hemi has a displacement of 5654 cubic centimeters, or 345.5 cubic inches using the standard US measure of cubic inch displacement.

The 5.7L hemi is not just a name for any hemi engine with a displacement of 5654cc, instead it is an actual name for the specific engine used in Dodge vehicles. The origin of the name comes from the fact that this particular engine uses a hemispherical combustion chamber design

How fast is the 5.7 Hemi Grand Cherokee? (0-60)

If you want some real power under your hood, then you’ll want to stick with a 5.7 Hemi V8 engine. This type of engine is typically found in the Overland trim level. This engine produces 360 horsepower and 390 lb-ft of torque that’ll get you from 0-60 mph in 3.5 seconds.

The 5.7 Hemi produces a respectable 360-horsepower and 390 lb.-ft. of torque. However, the engine is not all that matters when it comes to acceleration. The Jeep Cherokee is a heavy vehicle, so it takes a lot more power to get this SUV up to speed than it would take a smaller car.

For example, the Honda Accord with its 3.5L V6 engine only produces 278 horsepower but can accelerate from 0-60 in just over 6 seconds while the Cherokee takes nearly 8 seconds to reach 60 mph even though it has 82 more horsepower than the Accord.

Is the Jeep 5.7 a good engine?

The 5.7 Hemi is a good engine due to its reliability and power. The 5.7L Hemi engines are known to last around 250,000 miles with proper maintenance. They are also quite powerful for their size and can produce up to 400 horsepower and 410 lb-ft of torque in the most recent incarnations.

The 5.7L Hemi is one of the most commonly used engines in high-performance vehicles built today. It was designed and produced by Chrysler as part of their long line of Hemi engines which have been used in many of their trucks, vans, SUVs, and other cars over the years.

One of the reasons that this engine is so widely used by so many people is because it is extremely reliable and durable, especially when compared to other brands and models of similar engines. The 5.7L is also very flexible and can be used in a wide range of applications without much trouble at all which makes them very versatile as well as powerful and reliable

What is the life expectancy of a 5.7 Hemi?

The average life expectancy of the 5.7L Hemi is between 250,000-300,000 miles. The 5.7L engine, commonly known as the Hemi, has a bad reputation for early failures caused by a defect with the right cylinder head that causes exhaust valves to burn and fail. This defect was corrected after 2007, improving the life expectancy of later models.

Conclusion

The Grand Cherokee has only gotten better over the years, and for those looking to take a road trip in their jeep this summer, the 5.7 hemi is your best bet.

For those looking for more off-road capabilities, there are higher-end models with bigger axles and limited-slip differentials that are specifically suited for trails. Of course, top-notch safety features can also be found on all of them as well. It’s safe to say that the Jeep Grand Cherokee is a strong choice no matter which model you choose, and each option can be equipped to suit your needs.
