I was wondering what everyone thinks is the best engine ever put in a Jeep. It can be any engine to any Jeep vehicle but it must be a FACTORY engine. And remember you are more convincing with facts and statistics about durability, power, torque, anything. Although feel free to put in your opinion.
I am really looking forward to this thread. As a JEEP Virgin, I am in the market and have questions/concerns about the new v6. Everyone I know raves about the 4.0 inline 6, so I would assume it will be the favorite, but I would love opinions about other engines.
I'm a fan of the 4.2, but I have fond memories of my father taking a hammer to the carter carb because the needle valve was stuck on his 78 CJ. The 4.0 has my vote though because it was the perfect mix of technology and simplicity.

Yep, I'd say that 470 hp HEMI in the Grand Cherokee SRT would be at the top of the list as far as factory Jeep engines are concerned. The $70,000+ price tag seems a little high.
That is the irony of the Wrangler. Buyers are willing to pay a very large premium for a limited edition vehicles with high performance engines and suspension and Jeep fails to take advantage of this. Instead they offer special editions with badges, stickers and paint.

Had two of them, each went well over 150,000 miles before we traded one off, and my son totaled the other by rolling it a couple of times. Those motors were/are strong. I drive my son's 1998 Jeep now and again and am still impressed by that 4.0 inline six. Quite possibly the perfect Jeep motor.
Strictly speaking about the engine, I had 2 4.0s and 1 4.2 and I must have missed something good about them. With regard to Jeeps, I would have bought them even if they had the proverbial hamster in a wheel. Somehow Jeeps are not about the engine ...
The best is yet to come!
"A man has got to know his limitations."
The 4.0 is the best. They may have their issues but even the 4.9 fords and 3.8 V6 GM motors have problems. I've owned two jeeps and two fords with straight 6 engines and never had a problem... Other than hating the sound the exhaust makes. Soon I hope to add a cummins to that list.
The majority of problems I see on the 4.0 engines are malfunctioning sensors and leaking valve cover gaskets... I've seen em blown up before, but it's pretty uncommon. Normally the jeep is in the junkyard before it blows up.
noone even mentioned the little 2.5,.yea its under powered but its still a tank of a motor, and there is no real way of getting more power out of it except regearing and maybe an electric fan but they are simple to work on if u ever have to,,its not all about hp when ur deep in the back counytry one of the most reliable engines out there...so if u break down in the back 2000 acres in a new engine what good is the hps..,,,but my vote is still the 4.0,, tough rerliableand plenty of tourqe
i have had the little 2,5 it got the job done for years with no problems at all..
i hate all the new gagetry of the newer engines with all there electronic stuff thats just asking for trouble one of these days..
i have had the pleasure of driving the srt8,s and yes they put a smile on ur face everytime u mash the skinny pedal......
4inch suspension lift,3inch body lift,4.0 5 speed,8.8 with disc,s,16inch moto metal rims ,and some 35s..
with trail rash..and getting 25mpg,s
The 4.0 simply for the reliability if properly maintained. One of the guys in my wheeling group has a 98 Cherokee with a little over 300,000 miles on it and it's still going strong, he hasn't even had to rebuild it yet which is just amazing to me.
The 304 was rated at around 150hp. I'll take the 4.0 over it anyday. Anything seems fast with fender well headers and stubby little mufflers dumped out in front of the rear tires.
I think it would depend on what a person is looking for in a Jeep...
Power : Hemi-"My choice for newer Jeeps 97-06..obd2..
Sound :304-They have a unique sound..."Like a Harley".."MY CHOICE"4-older model Jeeps...to 1995..
Durability and easy to work on +fuel econemy : 4.0 I6.w/efi..All Jeeps..obd1 and obd2...
There are no other choices , any other Jeep , is a jeep looking for a transplant to one of the motors above......
NOTE; I'm speaking for Wranglers , CJ , TJ , YJ ..Only..
Only my opinion - LOL...Who's with me ??
