could be an interesting engine swap. Now sure if the ECU would control the AW4 but I'd be willing to bet it would be a drop-in and go type of a swap.

Anyone with any jeep diesel experience? Just wondering how they stack up performance wise compared to jeep gas engines? cummins diesel engines (4bt)?

Reliability?

Any foreigners to the US have comments?

The biggest problem with the diesel is the narrow power band. You're looking at 800-3000 RPMs, pretty much. Not saying it'd be all that bad, but you'd have to gear accordingly.

diesel gas sucks my ass!!


i had to say it:flipoff2:

if you want power, get a small block 350
i wish i had one
but NOOOOO
i have to be stuck with a 134 Fhead

They used older 2.1 diesels in Alaska MJ/XJ's here in the states. REALLY expensive parts.

You'd be better off with the Cummins 4B.T. Thats what I plan to swap in mine one day.

you can wish in one hand and shit in the other....
guess which one will fill up faster......:flipoff2:

Damn for the US $1,525.00 (current Bid) they want for them, i can get a junkyard 350/465/205, AND a 14Bolt/44HD. seems like a lot of cash for what it is. Diesel is cool, but i would go for the 4bt, or a toyota 3B if i wanted a 4-cyl diesel for a jeep.

Where can you find the 4bt engine at ?
Anyone put one in a cj5 before

They're in most every Fritos delivery truck you see on the road. You can also pick one up at the local Cummins dealer for about $8K.

I heard more like $12K from a dealer, and yeah all the dilivery vehicles have them but those engines arent easy to get ahold of unless maybe your a diesel tech or happen to know where those things go when they are retired and can rebuild them affordably because if you get a delivery truck expect several 100k miles on them.

I used to know a mech for UPS, I once inquired about how I would get my hands on one of those 4bt. Nada, not gonna happen. They, from what I was told, buy the trucks with out engine, rebuild the ones they have and install tham into the brown truck. Keep this rotation till the engine is really, truely FUBAR. I was informed they ave. three to four vans per engine.
Sweat moter.

UH?
in 15years of living here the only factory diesels I've seen here is a couple '97tj's. never seen one in a MJ\XJ. am I missing something?

Remember, alaska is a state, we just don't always like to admit to it.

I was told to look for a wrecked Fritos truck. I seem to remember there's a place in Ohio that had a few for sale that were the 3B's and not the 3BT's. They were used for a generator, but would work just as well.

check with Adelman's truck parts - they're in the Canton area, IIRC

Diesel Engine for a high perofrmance trail Jeep, or Rock Crawler, Huhhhh, am I missing something? Have they changed power plant requirements for a performance rig again, without informing me?
How much do those little oil burners weigh anyway?
Ohh I get it, some of you guys just like the idea of heffing diesel fumes all day, dont you? :rolleyes:

torque.

they weigh around 850 lbs wet :eek:

but if you arent concerned about weight then it is an awesome motor. stock 130hp, 300 ft lbs. easily tuneable to 300 hp, 650 ft lbs.

Well thank you for the little lesson on what a diesel engine provides.

But know lets go to rock crawling 101.

1:If you arent concerned about wieght, you arent building a seriouse rock crawler.
2:The need for monsterouse torquey engines went the way of the Mastadon, when the crawl ratios went above 80:1, and with the improvement in the wide power bands of FI gas engines.
Hell I could pedal my rig uphill at 200:1
3:Wheel Speed and instant throttle response became one of the most important factors in engine performance, the day after the obstacles started measuring longer than our wheel base and 90 degrees straight up.
4:A fuel injected V8 can be built to 300 HP and 400ft/lbs(and with a more usefull off road power band) for pennies on the dollar, and ounces on the pound of a high performance Diesel.

Now if you want a diesel in your tow rig, that makes sense.

I'm personally just in the research stages, but a diesel engine (as you may well know) is self contained. Wiring is minimal, no distributor so water is not much of an issue, they run upside down (much like your 302), and burn fuel more efficiently, torque curve is much flatter than a gas engine.

Again I'm just researching, and am actually leaning towards a 302 because of cost & weight savings over a diesel.

Check local equipment wrecking yards, they used 4BT's in some of the case loaders and backhoes. Some of the supers were turbo.
