Cummins 2.8 actually in an 80

[scottryana]

Depends on what trans you run behind it. If you run a 6 speed with double overdrive you could go as low as you wanted. These kind of projects are all about planning. What are your goals and how do you get there is what a good project manager does.

So this engine package isn’t really ideal for someone who wants to crawl as slow as possible with a stock trans and transfer case even with the current lowest low range gear set? Seems that way if you plan to run 3.7’s and 34” tides.

This isn't a bad option if you are looking for a diesel repower. Sure it isn't cheap though.

Wow for that price you can buy a built 6BT and a Diesel adapters kit have it installed and still have money to go on a trip to MOAB

Yeah, I just wanted to see what he had to say. I still want to put a 5 or 6 speed with compound low behind my 1fz but no one will make an adapter.

It is no where near a 4bt or 6bt bolt pattern, the motor is completely different , in all aspects the adapter plate is completely different so are all of the outside components AC alternator power steering pump built for a RHD vehicle . My buddy has one in his shop, we have been talking about what to do with this thing. I will maybe post something soon after things are started

Interesting, you'd think Cummins would standardize their bolt pattern amongst their own line?! Will the bolt pattern match ANY make tranny?

I see this as a nonissue, there are already at least 2, and probably more, companies making adapters. Advanced Adapter and Axis Industries. Axis has mated 2.8 with GM 6 spd and 8 spd (4.7:1 first gear) from HEMI, which surprisingly cost about the same as the GM 6 spd swap.

Axis has come out with several accessory bracket mounts to squeeze the 2.8 between the narrow frame rails of TJ. Kits designed around replacing a Jeep 4.0 I6 should be helpful when dealing with FJ80s.

Axis is in IN, just down the road from Cummins. Their focus is on Jeeps, but they have done the most work on the 2.8 from vendors that I am aware of. I spent an hour talking to them last year at Easter Jeep Safari. They had R2.8 mounted in a TJ on display.

The Axis adapter converts the bolt pattern on the R2.8 to an LS pattern. That means you can mate any GM trans to it, or adapt it again to whatever trans you want.

Awesome! You could use a Tremec T-56 Magnum 6 speed! I wonder what T-case would work with the T-56.

A divorced one. The T-56, while great in a car, has some drawbacks for use in a truck.

Fair enough. In hindsight, maybe a T-56 isn't such a great idea.

That adapter alone is $1400.

There’s nothing cheap about R2.8 swap, or realistically any other swap that involves billet parts. I used to work in prototyping and manufacturing, the price to get custom machined parts is very expensive.

 

[HDJdreams]

I would LOVE to have a turned up 2.8 with a 6 or 8 spd in my 80 (just look at my username) but after $9k for the motor, realistically it would be challenging to get everything else for $6k, that’s $15-20k for just parts and pieces.

I am guessing for someone like TorFab to put one in is $25-30k and I have no doubt that’s hard earned money on his part. That’s the better part of a new diesel Wrangler to just put a new motor and updated transmission in a 20+ year oil vehicle.

Instead, I am signed up for the upcoming turbo kit, and focused on getting the rest of the vehicle baselined and updated.

Well the R2.8 is a Chinese made industrial/farm equipment motor I am not even sure if Cummins designed it in any way for one thing everything is on the wrong side for LHD vehicle power steering AC alternator those need to be moved

Why does it matter which side the accessories are on? Engines are not really configured RHD vs LHD...in every vehicle where there are both variants the engines themselves are the same, just some different lines and plumbing to make it work.

Your comment makes zero sense, everything on this engine is in perfect placement. All the accessories are very well set up for a vehicle, even a cruiser. Also, this engine has been designed for use in a vehicle. The Ford Foton has this engine stock, and in south america they're used in Ford medium duty delivery vehicles.

Ok

Chinese made block, american assembled. The 5.9 were mexican or brazilian blocks but the motors were assembled in america. They still have a good reputation for reliability.

"It's built in China, and then shipped to Memphis, TN where we do the upfits needed to make it a crate engine. "

I am pretty sure the above came from a Cummins rep on another forum.

So if I read that bulletin correctly - they were in Denver on 2/10? Did anyone get a chance to see them? Kinda wished I knew about that, definitely would have swung by.

This is from their Day One post....

"My first impressions were very good. With a vehicle tipping the scales at nearly 6,000 lbs (we will confirm once we find a scale) plus four adults and gear, we were comfortably cruising at 75mph (until I learned that the speedometer was wrong and quickly backed down a bit!). Chandra told me how much they had enjoyed shaking this one down and that they too were impressed by the R2.8’s ability to effortlessly handle the truck. On their first tank of fuel, it returned over 23mpg - a tank of fuel for where they live consists of a lot of snow, 4wd, altitude (9,500 ft), and grade climbing. "
