Howdy - maybe I'm failing at using the search feature on the forum, but not finding any info on this conversion. I am finding threads pertaining to 40 and 60 series but nothing about a 100 series. Anyone have some intel on the Cummins R2.8 crate kit going into a 100 series?
 
:popcorn:
 
You have a Cummins in your Westy Camper?
 
2.8? Really? I mean, that would be cool in an FJ40 or an old Jeep, but they just don't have the power for a 100 series. Now, a late model 5.9 Cummins would be awesome, but that seems like it would be a tight squeeze.

5.9 or 6.7 would be an interesting swap, but they’re a lot heavier than the 2uz, 2.8 and 1hd fte. Wonder how the chassis and drivetrain would handle all that weight and torque?

562 lbs for the 2UZ vs 1,150 lbs 5.9 Cummins. I'm sure it's doable, but we're talking about major frame, suspension, and complete driveline upgrades with all of the weight and torque.

Years back, I had a Dodge pickup with the 24V 5.9 Cummins. Lots of easy cheap aftermarket parts made that thing an absolute monster.
 
I don't get the fascination with the R2.8, IMHO it's a cheaply made, poor quality engine that doesn't make particularly special power figures
 
I drove a stockish FJ40 with a Cummins 2.8 conversion recently. It seemed to move the truck just fine but the whole time I was driving it I was questioning that conversion in a heavy Land Cruiser wagon. I *really* don't think that the 2.8 will move a heavy modified 100 the way we would like it to. I've also heard that -because the engine isn't stock in a lot of vehicles in the US (any?)- parts availability for it is pretty spotty, which would be a big negative for me (I already owned a Land Cruiser with an exotic engine...trust me, not as glamorous as you think when it comes to parts).
 
Do it on an LX and watch the front AHC globes explode!
 
I like it in my FJ40 at 4,000 lbs, but when you get the whole family into a 100 at 6,000 lbs, that's not going to be a good time.

Because here in the Amazon Age, "Add to Cart" and have a new engine with an instruction manual show up in a week can be a lot more attractive than researching all of the different Toyota diesels, figuring out which ones are in what country and who you have to bribe to get them into the US.

I'm blaming Youtube for all this.

Somebody will put up a short video showing a swap and making it look like you can do a fine job in a very short time. Of course, in reality it actually took 2000 hours, nothing aligned properly and a bunch of parts will wear out prematurely because of that and/or because the new engine just does not work well in that truck. Let alone how poorly it drives afterwards. Etc. But it sure looks compelling on YT...
However much I love DIY, it's really hard for me to believe that a given individual, no matter how gifted, can do as good a job at custom fitting an engine (in a garage) as a bunch of R&D full-time engineers (in a lab) with the resources of a mega corporation.

I guess it's a matter of perspective. Nothing wrong with -and in fact kudos for- doing an engine swap if it's intended to be a fun exercise for the sake of doing it. Interesting, challenging, and fun. But if it's done expecting to beat the original engine, then I have my doubts that this is remotely realistic or a good idea in the vast majority of the cases.

But I can "add to cart" the correct Toyota engine/transmission mounts and almost anything else for the swap versus having to fabricate everything. ;)

1HD-FTE Weighs 762lbs, which is 200lbs more than the 2UZ-FE and 260lbs more than the R2.8. The 1HD-FTE and R2.8 have nearly the same power output (within a couple HP and ftlbs) with the R2.8 retaining its emissions equipment and factory warranty.

Yes, the R2.8 will be a “performance downgrade from the 2UZ-FE, but so is the 1HD-FTE by near the same exact margin, though I would believe the R2.8 would be slightly better performance wise.

I am not particularly interested in a diesel swap with the exception of fuel economy gains and I absolutely love the 2UZ-FE. However, other than being a purist (which I most certainly am) I see no argument where it’s compelling to go with the 1HD-FTE over the R2.8. The Cummins has the clear advantage, less weight, it’s factory new with a warranty, easy to source, same performance as the 1HD-FTE. The 1HD-FTE you have to source used, no guarantees of condition, parts availability etc.

If the 1HD-FTE works well for its application in the 100/105 and it does, I would contend the R2.8 would work better. It’s not a race car, it’s a station wagon. So, other than having a pure Toyota, I don’t see the arguments against the R2.8 being made here.

The OP has a specific interest and asked a specific question only to receive a bombardment of naysayers hating on his ideas and possible aspirations. What’s up with that?

'Tis a message board on teh internetz. And a 2+ year old thread.

Swapping a 2UZ seems like blasphemy. Would rather talk about swapping a Cummins 6BT into an 1855 Oliver with a scattered Waukesha 310.

I’m not sure I understand your point of it being a two year old thread on the internet? Seems to me it is still a valid and or interesting topic to discuss and consider.

Other than preference, bias, opinion and speculation, or a “seemingly blasphemous act”, what’s wrong with putting a R2.8 into a 100? Is it blasphemy, or does it just feel that way? I would contend those four items are irrelevant when considering a tech question.

Speaking of swapping a 5.9 into an Oliver, did you know Cummins produced a 6.7 12 valve? McCormick, now produced in South Korea makes the same tractor as case (mechanical wise) and they have a 6.7, p-pumped 12 valve.
