[1987rangerman]

this jeep had no problem spining its 32's in pure mud. she got all kinds of power

 

[Downey]

for all that work you can have 302 in there much easier and alot more power

Besides the inline 6 will outperform the 302 in low end grunt for off road use anyway.........on and much better MPG!

If you have it sitting there, by all means get out the hammer and sawzall and make it fit. There's nothing like a free engine!

I have a 92 explorer with a 4.0L V6, a kid I grew up with had a 95 XJ with the 4.0L I6. We did everything together and as such I've got a lot of hands on experience with both vehicles. Both of them are great engines and nearly identical in their power/torque curves (I just looked them up, they're within 5 ft-lbs of each other from 1000 - 4000 RPM with the ford leading by about 5 ft-lbs until 2000, while the jeep wins the HP game by about 15 HP at 4800 RPM). His XJ would blow the doors off my explorer but I'm guessing that had something to do with the 1200 lb difference in curb weight. Towing crap the explorer won hands down because of it's extra mass and the fact that it has a frame. Gas mileage was also a big difference, both vehicles were stock (in terms of lift, tires, and gearing) and the explorer managed to do 18 MPG combined to the 1200 lb lighter XJ's 14 MPG combined.

But since you've got everything laying there, stuff it in already!

i know no one wants to hear this but i have had 2 xjs and a comanche all three had that 4L and were unstopable. one of the xjs had well over 400k on it. still ran great. Ive had one 2 door one 4 door and the pickup. Also I drove the piss out of them.

Why in the world would a frame have anything to do with towing? and your XJ was running like crap if it only got 14 all of my 5 over the years have averaged over 20 combined

Oh and I towed a 14" tandem axle box trailer on my move from AZ to WA trailer weight was 3980 loaded. Oh and the jeep was lifted with 35's it did great!

XJ's are unibody. Explorers have a truck frame to them.

Tweak that poor XJ once and the truck become plagued with alignment problems, creaks, doors not closing right, the list goes on. Basically the same issues as the Honda Ridgeline.

Once that frame cracks, you're essentially boned.

Any uni body can be mended from most incidents, towing in no way would hurt and XJ enough to do any real damage, I know I have repaired a few that where throw aways. It actually takes a great deal to ruin an XJ. Yah know if you bend a frame on a rig it causes door misalignment, fenders out of alignment etc.......both can be fixed (for the most part)

Wow! Looks like somebody is getting a little over defensive about their favorite engine!

Let me be clear, I think the Jeep straight six is a great motor, as is the ford 4.0 V6. I've seen both go well past 200,000 miles personally. Also, if you comparge dyno graphs, they are almost identical in terms of output. That's really all there is to it.

If he has the jeep motor sitting there for free but would have to pay for a ford 4.0, by all means stuff the jeep motor in. Based on the dyno charts, it should perform pretty much exactly like a 4.0 V6 in a RBV. If you have to pay for an engine, the V6 makes a lot more sense because it fits in with all the stock parts and gives you the exact same performance.

As for towing with an XJ, it's definately possible. I've done it myself. But I've also done it with the explorer, and the explorer is just a lot more stable due to it's extra mass, truck chassis, and bigger brakes.

My buddy's 95 ran perfectly normal and got 14 mpg. That just what it did. I know another kid with the same jeep but with a 4" lift and 31's that is constantly complaining about his miserable 12 mpg. Then again my cousin has a 2-door XJ with a manual trans that gets 20 mpg. So go figure I guess....

 

[bobbywalter]

i have never even heard of a jeep 4.0 averaging 20.


while i think the xj is about as good as it gets...and i really like the 4.0....the only way i would have made mine better was to drop the 302 out of my ranger into it.


the reason i didnt is because it would have ripped it in half...poor michigan jeeps dont live long.

If you're talking about the Jeep straight 6, then don't waste your time. F--kin thing doesn't have enough power to get out of it's own way. My Neice has an 04 Wrangler with one, tried to drive it to Colorado a few years back towing a 500 lb trailer. After 60 miles barely making 70 mph and 9 mpg, I turned around and drove back and swapped the trailer onto my 06 Mustang GT. The Stang got 23 mpg @ 80 mph and never broke a sweat with the same load. Made up the 2 hours lost with the Jeep in the first 400 miles.

Something was seriously wrong with that Wrangler or you are fibbing to make your story sound cooler.

Yes, and the Ridgeline is a huge failure.
