Cummings Repower 2.8TD

Those 2.8L are great motors, have you compare the dimensions against a 4D56 yet? I would be worried about it eating our transmissions and xfer case thought. IF you go on youtube Dirt Every day did a few episodes about that motor and the conversion into his jeep. He is the one who drove it underwater for testing. Honestly the biggest fail he had was breaking the plastic oil pan on a rock.
 
I mean dont get me wrong I had a 1989 Pajero with a 4D56T and I had an intake, exhaust, injection pump tuned, upgraded intercooler, boost set at 25PSI a 4 inch lift and 35's the truck held up great but I also know how to take it easy on the drive train offroad. Truck made plenty of power but it had to be used properly. 1930767_1049053341464_8509_n.jpg 1930985_1047637786076_762_n.jpg
 
I was just talking to my friend Eric about this engine. It would be a killer transplant. I think I hear around 7K for the engine and harness. Not bad.
 
a lot of people have been swapping the 4BT for a long time it is a great engine with typical cummins reliability and parts availability with easy upgrades. Prior to this people bought old bread trucks for the motor, trans and wiring and swapped it. But buying a drop in kit is amazing to me.
 
Has anyone done this swap? I may be interested if the few mods (EGR delete, snorkel, short side exhaust) won't help with temps and power.

Driving to Florida to have Kellyn's shop do it might not be cost effective, unfortunately.
 
As drtydzel originally expressed in this thread, the biggest consideration (aside from figuring out how to fit it in) would be the transfer case/transmission compatibility. This engine has twice the horsepower and torque of the 4D56T. This has been the biggest/hardest lesson for Vanagon owners who've done conversions to engines with a lot less of a jump in hp/torque than this. These transmissions are not designed for this kind of output. Granted the vanagon transmission is particularly fragile, the ideal conversion, an early Z-tec inline 4 from the Ford Focus (which only has marginally more hp/torque than the original 2.1 liter waterboxer) has proven to be the most compatible as well as reliable for that application.
 
It's like changing all the drivetrains.. still has some respect with the Mitsubishi diesel 4d65 engines, maybe the reason why they didn't put so much juice is because it's dangerous for us to drive it crazy like a sportscar, difficult on turning, might rollover if you don't slowdown, it's a tank and I like the feel driving it..
 
For all the time and money needed for a swap might as well build a monster of a 4D56. I really like the engine and with a little work they make a very solid platform.

Still waiting for you to come out with the "Grant-Style" upgrade package... bigger turbo, intercooler, injector pump upgrade, bigger injectors... :D
 
Well it’s all pretty easy to get except for the pump as long as you can do the install yourself, might be hard to find a installer state side. I have thought about it but for the total cost you could almost buy a Hyundai crate motor I guess. Never felt like there was that much interest in the 4D56 but maybe I’m wrong. Guess I’m going to have to get the van on a dyno and get some actual numbers with all the upgrades.
 
Well, since my D4BF blew it's TD04-12T turbo, I'm in the middle of swapping it for a Kinugawa TD04-15G and hopefully get a little more power out of it. As for the install, I'm fairly decent wrenching on wrenching, but for that level of tweak, will let a trained mechanic do their magic.

will be interested to see what gains you get out of the 15T. I assumed it would be way out of the power band for the 4D56 since it would need to be at around 4000 rpm for peak turbo performance. You running a stock fuel system? What boost do you plan to run it at? If your heading towards 20psi, which I would think you would need with a 15T, you may want to think about ARP studs to keep from lifting your head. But maybe I’m just paranoid. Also the 130 nozzles might be nice to get a little more fuel as well.
