Modern Deisel Jeep conversions

Diesel Engine Conversion Contenders

1. 4bt
2. Duramax v8
3. BMW
4. TDI / Volswagon (might catch a little hell but good info and some badass engineering)
5. Powerstroke 2.8L ... 6.0L ... 6.4L
6. ...






Since the Bruiser thread sort of opened the door for a discussion on better suited diesel conversions I'm re-threading this with a more suitable title.

Bruiser is being set aside ... for now.

Got fairly "Bruised" over that one... Watta tasty Poop sandwich that one was... ... ...

jdemonto suggested the TDI which sounds promising. There is an informative emissions article at

ALASHA offered an intriguing BMW possibility. Looking into this.

I'm not vehicularly racist (or of any other sort) however I would like to explore domestic alternatives. What possibilities are there with a Powerstroke 6.0L or 6.4L?

Regardless of your personal disposition toward diesel conversions and smog do's & don'ts ... please try to keep the bashing to a minimum. This thread is intended to be constructive not destructive.

If there's anything I know about Ford diesels... it's stay away... stay FAR away from that 6.0L. The holy grail would be the 2003 7.3L (or the new 6.7L, but that's a LONG shot).

You need to be thinking smaller as any funk size truck diesel is way to big for the jk packaging. Domestically a guy in Canada imports a 2.8 powerstroke Ford light duty diesel.

Its not Canadian is a Euro Diesel made by International for Ford. Currently there are no light duty diesels produced in the states. Event the little 2.8 Crd Jeep liberty was from Vm Motori...Italy!

i worked for a rebuild shop that specialized in ford diesels for 6 years...rebuilding db2 pumps be ae injectors and turbos etc, i will never own a "powerstroke" and discourage anyone from it....yes the 6.0 was horrible...the 7.3 was decent but knocky...the new 6.7 is massive...

that being said

smaller izuzu and hino engines will fit in our jks...duramax is izuzu..,

personally cummins has my vote they are bulletproof...
4bt is a torque monster and an endless supply of parts and it super easy to work on...its a b series so you have plenty of interchangeable parts with ol faithful 12v

its funny how ppl say the 6.0 was bad...they only issue(and mine never had any issues) was the damn egr shit that would lead to head gaskets..simple fix was an egr cooler and erg valve delete..every diesel has its horror stories and weak points. but i agreen that a smaller td would be best

HPA is a VW tuning company that has put VW TDI motors in IIRC a YJ and it was pretty damn nice.

no that wasnt the only issue...ive rebuilt more 6.0 pumps that i can remember...more than any other pump that came through my shop...even more than the p7100 that was more than a decade older

"endless supply of interchangeable parts" ... key ingredient for a trail rig. Like the easy to work on aspect as well. Still looking forward to seeing an actual smog test on the 4bt... Haven't completely negated the "Little Bastard" yet!

Thx 4 the input... the 4bt sounds like the old Chevy 350 of diesels. Too bad we haven't heard something of the smog testing efforts in its' defense. Do you think its possible for the 4bt to pass a diesel smog without Bill Gates backing the build?

Last I spoke with Kenny or Jeff the price tag for a 4bt was around $22k for a well built conversion. More than a gas conversion but that's indicative of a diesel conversion.

wow i was reading the other threads..there are a lot of gassers that dont like the idea that a diesel would be a good transplant..maybe if they sat in a rig on 38s that ran a low 13 1/4 mile they would change their minds. ever since i ran my first tune from innovative i was hooked on torque

heres your smog test

4BT CUMMINS DIESEL BUGGY 49" IROK ROCKWELL - YouTube


but im sure since youre in ca and you have that whole certified clean idle crap going on youre gonna have to run some sort of filtering system...cummins new filtering system is pretty badass...(the new detroit is even better) but maybe some sort of small scale scr (selective catalyst reduction) system might work...maybe tune the pump back a little lean, whatever needs to be done it can be done...

im no engineer by any stretch of the word but from what ive been seeing just from hino (a toyota group) the shit they come up with is incredible...been doing alot of warranty work for excessive black smoke power complaints etc...what i used to do (up until this MY) is replace injectors, fuel pump, and different controllers....NOW the engineers have figured out the programing so that i can just recalibrate the injectors and fuel pump with a laptop...boom pow trucks back on the road in a few hours vs a day and a half

you can get factory rebuilt 4s straight from cummins now...just got a flyer a few months ago....

yea i know what you mean...i have the same feeling towards gas that they have to diesel...to me diesel is so much easier and easier to make real power...not just a bump in 15-20 hp/ft lbs but 100 ft/lb boosts with one hx 60...not to mention water/propane injection

How does it face off with the Bruiser ?

Second

I'm all about the 4bt. Or other 4cyl turbo diesels. In 2004 I had an '85 Pajero 4cyl TD (mitsubishi montero) while in Australia and it was fantastic. The thing I enjoyed most was putting it into 1st gear 4lo and letting out the clutch (yup it was a 5 spd) and crawling up sandy banks after crossing a river. All torque right from the get. Easy to manage power without high revs. Then you get the economy... I drove the entire east coast of Aus and averaged 34/36 mpg some hwy lots of dirt, fantastic. When I came home I was talking to buddy about putting a 4bt into a yj. Jeff beat me to it.

22k is expensive for an engine swap but it is worth it for a complete shakedown turnkey swap.

I had the opportunity to checkout Jeff's personal Bruiser 4bt while I was in FL. It is a beast. Though I wasn't able to take it off road you could tell the power was there. It's not fast but it was turned for economy and will go 75 all day long on 37's without breaking a sweat. It is awesome to feel the power at 1k rpm, the ability to pass on the hwy and still not have to run the rpm's above 3.5k. Easily controllable power that is usable without stressing the drivetrain. If you are going to EJS take the time to go check it out. It has made the short list for my JK once I've paid it off.

I did the math and at the current cost of diesel in CO it would take 13 years to pay back the cost of the conversion with fuel savings. That's if you run regular diesel, if you run waste veggie oil you'll pay yourself back even quicker. I have an 05 dodge 2500 with the 6.7L cummins with just over 50k miles on it and I only get 24mpg out of it when I'm not towing the horses.

Sorry for rambling. If you aren't sold on the 4bt cummins, Do find a 4cyl TD engine of someone's. The power vs weight and mpg is undeniably fantastic.

Does HPA have and vids of their jeep actually moving?

The Mitsubishi 4M41 motor would work well.... (it is the current day 3.2 liter version of the motor that you had in that old Pajero)

What about the 5 cyl Mercedes motors in the Sprinter vans? With as many as are out there, there has to be a supply of wrecked ones.

Keep in mind, the goal here is not to simply find a diesel engine that is awesome powerful; but to find one that also has low enough emissions to pass that portion of the smog test when running on everyday diesel.

As I've mentioned in several replies, it would sure be nice to see some tests on the Bruiser.

Same goes for the TDI.
