ok mr i know every thing because i seen it in a magazine and everybody else is stupid, and i can give a **** less who bob sheaves is really,

people do it every day

Wow, you really have no idea. Aftermarket, no problem. Out of the factory, on an assembly line? It takes millions of dollars in certifications. Cooling, heating, side clearance, hood clearance, radiator clearance, crash testing, emissions testing, durability cycles, parts sourcing, fit on the line, ect, ect, ect.

As a side note, Mr. Sheaves is one of the reasons that TJs have solid axles. He was part of the team that designed Blue Devil (IIRC, that was the platform testing name) that was eventually chosen to underpin the TJ. You SHOULD give a **** who he is, honestly.

EDIT: Sorry, it was 'Lil Blue', along with 'Red Devil' and 'Screaming Chicken.'

the isf 3.8 is an inline 4 cylinder, so it shouldn't take millions to see that clearance is not an issue, the engine is already in production so emissions & durability test have already been took care of by cummins, price wise they are going to have to do the same testing with the motori diesel, i choose cummins over motori anyday

Four cylinder no way , you have the v6 already ! Go up in cylinders to a v8 keep going up not back ! Jeep already has two v8 5.7 ,6.4 they could do a v8 diesel it do,s not have to be a big v8 it could be 4 L to 5.7 L . Toyota do a 5.7 L v8 in a ute .so how big the GC is should not be a problem as ute,s are lite in the *** end and Toyota had no hassle putting it in her and when I say utes ,i am talking about all utes on the market ! All of them are lite in the *** end , that's so you can put a load on or in the tray on the ute .lol

this is on a inline 6, 5.9 cummins with bolt ons and programing, the 728 was with smarty programing and 760 with efi live, v8's are over rated

all im saying is you can get 300+ hp out of a 4 cylinder diesel with easy bolt ons like injectors, turbo & tuning and with that you should have 600+ ft/lbs of torque so why add the extra weight of a v8

I was wondering a 4 cylinder engine isn't harmonically balanced like 5,6,8 or more correct? You need a specially balanced crankshaft? So a 5,6,8 cyl will actually run much more smoother powerband than a 4 right?

And for aftermarket concerns it is much more expensive to produce more power from a smaller engine to equate the same amount of power and torque of a larger engine.

I am not trying to bias but I had 4's and never liked them much. The last one I had definitely put up some nice horsepower and torque numbers, but the problem is as these manufacturers squeeze more power and compression out of them they are using engine blocks with thinner walls and lightweight cheaper pistons. Of course, they are not just doing it to 4 cylinder engines only, they all seem to be going this way.

After religously changing the oil every 4-5K using only synthetic oil and premium gas on my last vehicle a 4 cylinder, at 80K I was burning a 1qt every 3K miles.

I don't think you need 5.9 cummins Diesel in a Jeep although it would be fun to have but 3.0L would be great or 4.7L v-8 Gas, especially in a new Lib since it is pretty heavy.
