kosmo04 It's impossible to run a strong tune without blowing smoke, it happens. My F-250 even on my strongest tune which pulls about 650 horsepower and 1300 ftlbs of torque smokes a decent amount, and no matter how much you play with it you'll always be smoking. DPF's KILL diesel trucks power, fuel economy, and reliability, sure they stop a little smoke but what do you do with the soot and carbon once you empty the filter?

This is a bit off topic, but I wouldn't start pointing fingers and blame smogging and everything else on diesels. You can still build a great diesel engine that produces very little coal, Audi and VW do for example, but for performance wise it won't be anywhere near a non-DPF/AdBlue diesel.

I'm done ranting, and would love to see more diesel Jeeps around.

I'm not sure what you call rolling coal, but blowing huge clouds of black smoke is going to cause problems with tree huggers. Its the guys running smoke tunes and billowing black telephone poles out their stacks that caused the idiots in CA to start smogging diesel trucks. If there were more offroad vehicles blowing smoke like that truck, there would be more closures. I'm as big a fan of diesel as any guy, but I also know that if its blowing smoke like that, it's either not tuned properly, or the injectors are so big that the tuner can't properly control them at lower throttles. I also think that diesel tuners are offering a disservice to the diesel community by offering "smoke" tunes and doing half ass calibrations that blow smoke. If its a offroad only competition truck, sure, you can dump massive fuel in there to try and use a couple extra psi of boost and keep the engine from melting.

pickupman2500 but it doesnt roll coal. i am diesel guy man. i bought a hemi once. ONCE. never again. i have had 3 diesel rams and one hemi. i owned the hemi for 3 months. i am not diagreeing by anymeans i think v8 jeeps are cool. but something about diesel jeep is just plain awesome. i swear if the new wrangler comes out with that v6 TD i am going to buy it. torque horsepower cool sound and best of all killer fuel milege hard to beat.

Actually a better and more accurate reply would be "Nothing beats a set of 44 in stickys."

While impressive not trying to discredit the builders, gearing and TALL, sticky tires are more responsible for the JKs performance than the 6BT alone. The same jeep with a Hemi motor or LS V8 would be a beast too.

But I mean if I had a million....

That thing sure has a crappy tune with all that smoke I'd love a small diesel in a jeep, but not a full size cummins!

UFOtestpilot Yeah, since there are entire websites dedicated to 4BT swaps I just assumed the OP was inquiring about the 6cyl behemoth.
03-08-2013 01:24 PM
Skurvydog22 I talked to a guy that did a 4bt swap for about 1500. Bought a delivery truck for 3000 with the engine, took the disc breaks and the engine. Scrapped it for about 1500 (all aluminum body) and did all the work in his driveway. He is a ridiculously smart and comes from a family of mechanics so he did all the work himself.

I would consider this extremely cheap.

A full size cummins swap is a whole different ball game considering the sheer mass of the engine. So I couldnt even begin to imagine the costs.

Skurvydog22 Like a full size 6 cylinder cummins or the 4bt?
03-08-2013 01:18 PM
UFOtestpilot I'm pretty sure the 1000 lbs it weighs has prevented anyone from seriously considering it as a viable swap for a wrangler. Then again, I've seen (and done) some incredibly silly stuff in the name of curiosity and stubborn determination.

Cummins swap price

Just curious if anyone's done one what was the cost of doing it
