anyone stuffing this lil motor in a k5 yet ?

Watching today's show, learned it has its own built in mechanical fuel pump, so gas tank wouldn't need modified other then possibly return line

Seen motor trend show, they putting one in a replica land cruiser
 
It’s a slug...
And it cost my buddy over 20g’s by the time he was done.

Ah ok, I know hp was low but seemed to have good tq number.

In all seriousness, my buddy did that whole swap in his TJ and honestly he should have left the 4.0 in it
 
oh I believe ya, hoping they keep showing the build so I can see how it does in their land rover , I know I said land cruiser but it's a replica 110 land rover
 
Ian's build on 4wheeeler and he also did it to a willys wagon on Big Tire Garage,
 
Good little engine for the most part, been used overseas for a long time in commercial trucks. Similar torque to the 6.5 diesel.

If you want torque at low rpm and crawl, it's a good choice. If you prefer being over 2500rpm then gas is your option.
 
Fred Williams has one in Tube Sock, his white TJ. It was sponsored by Cummins so it is all good press from Fred and Motor Trend. Looks like it works fine but I bet the jeep fully loaded with gear still weighs 1000 lbs less than a K5.
 
I bet if you got lots of cash to spend it would be cool.
So would be a 4bt … if you like loud and off balanced.

I would do a 4bt if I could find one cheep. But not for a daily driver.

For the price of one of those you could start out with an L29 roller cam big block, good heads, hot cam, Edlebrock pro flow injection system, fuel system and still have money left over. It will pull like a freight train down low and loaf along at highway speeds with plenty of torque on tap.

On top of that zero fab is required. It bolts in, no adapters to the trans. Like God himself intended it that way.
 
Are you talking the Nissan engine? It looks like there is a 161HP/310TQ and 210HP/385TQ version. The only interesting question is MPG. The performance should be like a 6.2L diesel, but a couple hundred lbs lighter. Since a 6.2 can get nearly mid-20's in a square, seems like upper 20's could be reached with direct injection, etc. 3.0L Silverado is rated at 33 highway. What kind of MPG does @Alan2smiley get with his 3.9L?

The 4BT I have in a CC with a NV4500, 12.5 37's, 4.10's loaded at 7000 LBS averages 18MPG. What we do doesn't have to make sense or be practical, it's personal preference to satisfy ones curiosity. :D I think 2.8L Cummins crate motor is to small for a full size rig.

This. I love odd engine swaps, and I like inlines and diesels. I even am patient enough to live with a slow engine. I should be their target audience.

But this engine is nowhere near compelling. Too much money for not enough engine. Many better options are out there.

For quirky or unusual swaps in my mind the basic hardware has to be value priced because you're going to be giving up a more suitable option and you're spending time and money on fab work. IIRC those Cummins engines start around 9 grand just for the basics, to say nothing of how you're going to get it in the truck. The math just doesn't work out when there are many other far superior and cheaper options out there. Even if you wanted to do something weird and different, you could do so a lot more reasonably.

Which is exactly why the only R2.8 swaps I know of are magazine builds or "influencer" built like Ian Johnson's Willy's.

The R2.8 is a cool setup for a lighter vehicle like Jeeps or similar. Not for a fullsize.

The smaller rigs are their stated goal market. Wrangler, Tacoma, etc.

As for the price tag, Don't forget it includes the adapters/wiring, essentially everything but the frame side of the motor mounts cut to shape. So when new small block v8 crate engine, stand alone computer, wiring harness, everything else needed for a swap it's actually not far off.

Of course can always go cheaper by swapping a used engine/trans from a donor rig, no manufacturer can compete with that.
