Perhaps I should have elaborated more, but I said gearing because I was thinking of stuff like the early Go Devil 4 bangers. The Willy's Jeep would go through just about anything with 60 horsepower and 105 lb ft of torque.

That was actually considered the High Powered engine when it came out!

Has anybody done it? Is it worth it? Obviously I know gas will be even worse but what are the pros and cons of this? Remember that this wrangler will be mainly a daily driver.

hey just to let you know i have one for sale. it gets about 15-20 mpg no lie! it is actually really good! i love it! attached is the link to my ad:

Pretty sure there was an SRT-6 in the Chrysler crossfire. I'm not sure if it was just suspension and those types of upgrades but it may have had a better engine

Just to let you know too, the person on the first page said it would be about $10,000. The guy that built mine and others that I have seen that you could trust to drive them from PA to CA and back 10 times costed them around $40,000 if not more. I mean just think about it to get a nice jeep with low miles your gunna pay atleast $10,000 (depending on the year) Then you need to find just a hemi motor or the whole car/truck with low miles. Thats gunna be, I am really not sure out of the junk yard $2,000???? or more, not sure. Then all you have is the jeep and the motor. You still need to get all the wiring and conversion stuff. And then you need to make sure the computer matches with the motor. It is really confusing when the guy told me about it, I know I would never have enough patients to do it. I am just letting you know, not trying to start any fights or anything

My JKUR is probably pushing 5,000 lbs. with the bumpers, skids, wheels & tires. The 5.7 Hemi is the same one used in a Ram pick-up. It's not a neck-snapper by any means, but it will get you down the road. I drive reasonably sane on the road and like to fashion my off-road driving style referred to by the late Granville King (look him up if you don't know who that is) as 'driving elegant'. Spinning tires means lost traction. Speed breaks things. Do I need a V-8 Hemi in low range? No way. But, it drives so well and has so much more torque that the 3.8 slug that it drives far better slow and controlled in the rocks.

As for warranty issues other than drivetrain, my dealer has replaced the sway bar disconnect three times now. At $1100 - $1500 a pop, that's pretty significant. I was assured that if anything went south with the transfer case or front/rear ends that there shouldn't be any problem covering those under warranty, either.

So what do you do on extremely loose trails or ones that have mud on them? Do you not even attempt them since you know you will have to spin the tires on them? What happens if you travel somewhere to wheel and it rains, do you just stay off of the trails?

There are lots of different types of trails and in lots of parts of the country even a tube buggy with sticky tires have to spin them to make it up things. To me if someone only wheeled in spots where the tires never spun they would be limiting them selfs on where they can wheel.
But at the same time if you only wheeled in places with great traction this is a great mindset.

I LOVE my 6.4L HEMI in my JKU Rubicon. And it is neck snapping fast...

I also have had a 5.7L and a 6.1L JKU both were awesome too. The 3.8 is way inadequate for a JK Wrangler, the new 3.6 is MUCH better and with a supercharger on the 3.6, I bet it would be AWESOME too!

I vote got Going For It!!!

Yeah... But im gunna tell u now its not 4-10,000 job. If you look around an find the very few people that have them an did them right an the jeep looks like $100000 not a thrown together mess theyll tell u your way off with the price. I mean the one guy just said the motor was $2500 to buy a really nice jeep yet tooo depending on the year pretty much nothing under $8000 an then the conversion stuff which i found were between $4500-$6500 an then you have to make the computer match the motor which is a lot an you need to get the title to match the jeep an the motor

I'll put a Hemi in a TJ and warranty it for $10.000.oo .. I've done 2 Hemi swaps so far One in a 01' Dakota quad cab and never got close to $10.k . Both looked like the trucks came from the factory with Hemi's..Check Dodgeforum.com and go to Dakota Hemi Swap with pics.. I'm looking for a 5.7 Hemi for my TJ now.. IMO it's one of the best swaps you could do..

If he's talking about a 3.6L Wrangler then the NAG1 auto trans can withstand 500HP in stock form.

I don't see a 5.7L Hemi ripping out Dana 44's and a NAG1 transmission unless you take it to the drags and run locked in 4 Low ... with slicks on all four corners and you don't stage the Jeep correctly.

The worst that will happen is you will snap a drive shaft or two.

Interesting fellas. Lets not kid ourselves here; putting a turbo or a supercharger on a 6 cylinder is never going to equal a V8 in across the board power, nor was the 6 intended to support the load that one of these is going to give it. Motors are always better when they are left stock; just need to get one big enough to do the job.

I have had 3 hemis, have an Aspen with a Hemi and Ram crew cab with a Hemi at the moment (and an LJ). I'll take the truck Hemi any day. Put it and the tranny in a 4 door JK for sure. Only way I would own a Jeep as my daily driver. I need it tow a trailer from time to time and be able to load it down with stuff. The Crew Cab moves out quite nicely, dont really need any extra power.

I emailed Chrysler; still not interested or unable to put the V8 in there. So I need to go aftermarket.

i have had 8 Jeeps, 2 CJs, a YJ, TJ, XJ, ZJ (with a factory 5 speed), a WJ have an LJ now. After driving a '13 wrangler as a rental, it drives so good it could easily be my daily driver; except that pitiful engine in it. So, my plan in a couple of years is to find one used, maybe with some defect like the heads where someone kept driving it and the engine is fried and drop the Hemi in there and maybe by then an 8 speed tranny. I thought I was going to do that to the LJ but the difference in how they drive is incredible. If you started out like me, with a 77 CJ7 Golden Eagle (with a built 304) and add a leafs, you can really appreciate how far Jeep has come.

If they could build it, doesnt matter if it was 70K, people would buy it, trust me on that. Look at all the ridiculous overpriced sedans out there or the special edition mustangs and Chrysler SRT products.
