hi, just wondering if anyone of you has seen this or are considering it for a Jeep platform.

It’s not entirely clear to me that it’s California legal. I saw some language indicating that they expect it to be, or that are in the process of completing that legality.

Assuming they get the legality worked out, I think it’s a cool idea. It appears to be essentially designed for Jeep-size vehicles. I would love to have one in my K5, though it’s pretty low on the list since the gas 350 still works fine. 161 hp and 267 ft/lbs of torque are not eye-popping, but should be more than enough especially with diesel low-end torque. Mileage would obviously vary per vehicle weight, gearing, tire size etc. but certainly would be a massive improvement over any gas engine. 

the bad news is that $9000 price tag.

comments?

Probably too small for your K5 unless you plan to put that thing on a diet, wait a couple years for them to release the 5.0 crate motor.  2.8 is perfect for the Jeep platform and some toyota platforms. (specifically all those yota 3.sl0w craptacular v6s)

Still waiting on Cali to make a decision on the emissions thing but on paper it meets all of the requirements for 1st gen OBD2 vehicles.  The cutoff in California will vary by brand and when they switched emissions schemes but figure 97 to 99 and earlier should be legal.  

As to the price tag, everything seems expensive to how cheap chevy v8s can be found in salvage yards. For what you get it is incredibly reasonable. A fully dressed crate motor ready for “3 wire hookup” can easily exceed that.  For example:

Everything is California legal if you buy pre 1975. You can get some awesome early CJ or Willy’s Jeeps or even and early 70’s Suzuki like I’m building.

If your interested I know where 1 more 70 Suzuki is and it could probably cheap and then just put anything you want on it…cool

Well legal and not needing smog are two different things.

Very true.  Could swap the motor into anything you wanted if you first had the vehicle registered and smoged in your name in a county which doesnt require bi-annual smogging.  (Lake, Mendocino, Plumas, Alpine, Amador, and parts of Placer and El Dorado are all change of ownership smog only)

Couldnt ever sell is in state but would be registered and insurable.

Um...what?

Assuming Cummins has the legality worked out, it is pretty safe to assume that this brand-new engine should not have any trouble passing diesel smog for many years. . . agree?

Depends on what year you put it in.  97 and older diesels are smog exempt in CA.  Again it will depend what year the new vehicle is and what emissions level was needed but could be as simple as a one time BAR inspection and then nothing even in bi-annual smog areas.

Not needing smog is legal and doing what ever you want to a smog exempt vehicle is also legal

Unless this is different European wranglers offered the 2.8 as an option.  Mileage was 28, which would be pretty nice.  It is not CA legal, and was not being considered for import last I heard.  The 3.0 was what I heard they wanted to use.  However, didn’t that motor also get an investigation?

Different engine from a different company. Jeeps in Europe and the early 2000s libertys in the US use/used the 2.8 from Venturi Motors (Italian). The mileage you mention is right on target though. Couple of videos mentioning 32mpg on 31s and high 20s on 35s

I read an article about the Dodge/Chrysler/Jeep/whatever 3.0 diesel. I think they put it in Liberty vehicles? The article mentioned that it had pretty serious problems with some type of sensor malfunction. Also you have to add the “blue juice” diesel fluid to it regularly, not that big of a deal, but still. I also think the article said that that engine is under investigation for the Volkswagen-type software “problem.”

I spoke with some Italian jeep owners and they said they would way rather have the 3.6L pentastar which I find fascinating.  

Um...what?
