What I had said was that GM was selling VM 2.8l crd engines that they installed in their Colorado pickup trucks and SUVs in the Australian market branded at Duramax - with a simple plastic engine cover saying Duramax. These vehicles are manufactured in Thailand and GM is making the engines there under license from VM. I have seen them up close and they are VM engines, identical to the JK CRD export model engines.

Actually...the GM has a number of internal (and external differences) compared to the JK engine.
For MY12-13 there's a different turbo, different injection system (solenoid for GM engine vs piezo for the JK), some internal differences for the balance shafts, intake manifold, etc.

About the only thing similar is the external appearance. Remember that they're a licensed engine, so there are a number of differences also accounting for the fact that they're built in-country.

The 6L80 will definitely NOT fit in the KJ, if not for the bell-housing adapter then for the electronics interface to the rest of the vehicle.
220hp and 380lb-ft sounds too optimistic for the 2.8L engine. I wouldn't expect much over 200hp, if at all.

I am sure it wouldn't be easy, nor would it be worth it. The OD's are the same anyways.

Looks like that Holden does 200hp/370lb-ft, i bet its the same or lower.

Why does 220 hp and 380lb-ft sound too optimistic. The older outdated 2.8 in the KJ with a GDE turbo kit will do a little over 200hp and 400lb-ft. The older 2.8 has a really poopy designed head and intake the restrict flow. So I would think with 8years of design changes making 220hp would not be a issue at all

From what I have read, Nissan's diesel will be a Cummins! :BANANA:

Quote:

Nissan announced that it will be putting a 5.0L V8 diesel engine built by Cummins Inc in the next generation of its Nissan Titan full-sized pickup truck, due out sometime next year. Boasting more than 300 horsepower and approximately 550 pound-feet of torque

Dodge will have a VM 3.0 motor.

Quote:

the Ram 1500 lineup to be featuring a 3.0 liter turbo diesel V-6 built by Italy’s VM Motori, the same diesel supplier to Chrysler since 1992. horsepower is to be rated at 240 horsepower and 420 foot pounds of torque

Dodge will use urea injection, not sure about the Nissan.
Notice the big displacement size difference!

Nissan with a domestic built diesel, and Dodge with an Italian one. I would have thought Dodge to stay with Cummins. :shock:

I think Chrysler 's idea is to make the 1500 more fuel efficient, but that truck is a big heavy cow, not sure why they don't offer at least 2 diesel engines...

Everything Chrysler builds is overweight for the size, so it doesn't surprise me that they would want to focus on a smaller engine for better economy.

As for the switch from Cummins to VM... Why is this a shock to anyone? Fiat now owns Chrysler, and Fiat now owns VM. The Italian company obviously prefers to use the Italian engine manufacturer, leaving the American engine manufacturer to sell to anyone interested.

I'm excited about the prospects because Nissan vehicles are decently reliable, and Cummins engines... Well, I don't think they have ever had a clunker design, have they?
No more Chrysler products for my family EVER, but this Nissan truck... That could be a possible future toy.

WWDiesel · **Posted:** Tue Nov 26, 2013 10:07 pm

I agree Geordi,

a Nissan may be in my future since I have a very good friend who is the Nissan dealer in this town and he is already talking to me about trying one of them, and some are made/assembled here in the states in Tennessee. Not sure if the new trucks will be made/assembled at that plant or some other location. :?:

Dealer friend gives me very good deals, like his cost plus some change, daughter just bought a new Rogue from him.
He also sold me the Jeep CRD way below anything I found listed on the web.

The GDE turbo kit doesn't have to meet long-term durability standards like a production engine needs to - i.e. xxx or xxxx hours at max power output.

About the max the 2.8L is giving right now is 200hp continuously, to get power beyond that means to run with exhaust temps, etc that are beyond the components ratings.

Also keep in mind that adding on the SCR aftertreatment for the US adds a lot of backpressure due to the DOC + DPF + urea mixer + SCR catalyst + pipes and muffler(s).
As the backpressure goes up, the achievable power goes down.

.........

Both the Ram 3.0L diesel and the Nissan will use SCR aftertreatment for NOx. There's no way to get around it. The Ram has the same system of the WK.
The Titan with the 5.0L is going to be an absolute beast, especially if you need to tow a lot.

99% of a motors life is spent in low load if its used as a DD. How many times do you drive around in the week at peak torque for extended amounts of time

If the 2.8 cummins(that was first to go in the titan) can make 210/385 with having all the same emissions parts to meet tier 2 bin 2 requirements. I don't see why the 2.8vw can't do the same. SCR,DPF and DEF have been used over seas long before we started using it in the states.

Yes the Titan is going to be a beast. I can't wait. The wife and I will be ordering on as soon as we can.

I see that people are tuning the new 2014 JGC diesel. Friend said a guy just posted dyno# of before and after tune
Before 197/340
After 213/352
Hope those #s get better

MrMopar64 · **Posted:** Thu Nov 28, 2013 12:02 am

Where did you see info about the new 2014 JGC being tuned?
So far the ECU hasn't been cracked, I've only seen in-line plug in boxes that are more dangerous (potentially) than helpful.

My friend sent me the info. He is on Jeep garage. After looking not a ecu tune but a BlueSpark box.

Almost seems like they are overrating the engine at the factory a little

geordi · **Posted:** Thu Nov 28, 2013 11:15 pm

Are you referring to over-rating the VM engine or the Cummins?

The Cummins is a 5 liter V8, 300HP and 550 Lb-Ft doesn't seem overly optimistic. The amount of power that the VM 2.8 in the CRD was able to produce was fairly impressive too.
A four cylinder being able to pull 7000 lbs and get 19mpg doing it? If the Cummins lives up to half that capability... That will be a VERY impressive truck.

No I was talking about the Grand Cheerokee EcoDiesel

I am really liking the Colorado with the 2.8l (I started another thread before I realized this was still active)

I wonder if coupled with:

6spd Auto; more aerodynamic truck; and 2wd we would see 30+ mpg on the highway!? And tow 6700 lbs!

JDaPP · **Posted:** Fri Jul 29, 2016 7:08 pm

Now that the Colorado with 2.8L is out, how close is it to the Liberty's 2.8L? I.e. would our knowledge lend itself to working on it? Would GDE be able to make a tune for it?
Along those same lines how close is the 3.0L in the Grand Cherokee to the Liberty's?

tcoilburner · **Posted:** Fri Jul 29, 2016 11:43 pm

The engine has a lot of different designs changed from ours. GDE is already got one tuned, but not for purchase yet. Early fall maybe. Keith was doing him normal durability and drivability testing before he releases it. He has stated some impressive mpg for it, I hope it stays that way in final form.
The 3.0 in the Grand is a v6.

diesel_guy86 · **Posted:** Sat Jul 30, 2016 10:41 am

Dan Clarke at Dans diesel performance has already tuned quite a few, as well as mark at Danville performance. Hell someone has already twin turbo'd one and is putting out impressive power.

Im sure the better head design helps, id have to say this is the biggest weakness of our engine.
I know the newer engines use a regular "drop in" crank but i think theres something to be said about our "tunnel ram" blocks. I know its a wierd design but i like the idea of having the bottom end all one solid piece. Theres no caps to wiggle and bolts to distort anything.

In the 6.6 duramax world going north of 100hp/liter requires at minimum ARP main studs, from there you can get billet caps and a girdle, all to do the same thing that we already have. Im right at the edge of 100hp/liter and i havent touched the bottom end.

Is there a build log for the twin turbo?

diesel_guy86 · **Posted:** Sat Jul 30, 2016 11:18 am

I googled and found this, http://www.duramaxforum.com/forum/2016- ... &_k=2lun2n

On page 6 it says he popped the motor at 300hp, but appears it was the 2 bolt main caps. Like i said, im a fan of our engines, just have a dumb cylinder head.

And heres there kit for sale: http://www.sdptwins.com/sdp-compound-tw ... let-turbo/
They're currently at 300hp/570tq on stock everything.
