Cummins R2.8 swap into 100 series

[westfaliacamper]

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?

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.

You revived it scolding people for their responses. Whereas you could have just said:

Re:

Is it blasphemy, or does it just feel that way?

This seems like some John Locke type rhetoric.

Re:

did you know Cummins produced a 6.7 12 valve?

12 valve with that many cubes? I'd rather have 24.

It’s was not my intention to scold anyone, you may have read it wrong. Seems to me I was just pointing out something that was pretty obvious to me. I did not do it in a rude or accusatory way, and I certainly don’t see how you or anyone can dispute the comment. If you can refute it directly, I’ll concede, or am I to interpret your comments as passive aggressive “rhetoric”, . There are several people on this thread who have either helped or influenced me tremendously on my own current project, and my comments are not a direct or indirect attack on anyone here. The next time make such a comment I’ll put a smiley face for sensitive folk…like this

I don’t know who John Locke is. I’ll try to look it up or maybe help me with the reference .

Either way, it is an interesting fact that very few people know about.

Are you familiar with the saying; when you throw rocks at a pack of dogs, the one that yelps is the one you hit?…

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?

Have you ever driven a vehicle powered by a 1HD-FTE or an R2.8?

I have not. I have owned and driven loaded down 2F, 3FE and 1FZs. Currently I have a 2UZ-FE which I love. If the 1HD-FTE or R2.8 perform as well or better than the aforementioned petrol inline six’s, they would be more than fine for my uses.

The R2.8 has adapters to mate to different transmissions for various vehicles. Jeep, IH, Toyota 40s and 60 series. There are adapters for F series bell housing that are very straight forward.

The adapter I have took a Cummins flywheel and demassed it to have a ring gear to work with the Cummins starter and a hub and plate. The hub takes a 2F flywheel and the plate bolts up to the Cummins bell housing and Toyota bell housing.

I have seen other adapters that have a flex plate with the ring gear to mate with the Cummins starter but had problems with the weld breaking and the ring gear coming loose.

The real world power delivery of an FTE and an R2.8 is vastly different. Numbers on paper aren't the be-all and end-all.

Can you please elaborate on the "vastly different" part? Genuinely curious if one Cummins is more suitable for daily driving duties, being a much more modern engine!

Ummm, the car actually came with the FTE engine, it has oodles of aftermarket support and power upgrades, it will bolt straight in with factory equipment, it doesn't require buckets of cash just to fit it in and you don't need to jump through expensive compliance hoops. Seems compelling to me

The small diesels that produce 'respectable' power figures are very boost-dependent for want of a better term, so have a very laggy feeling off the mark, especially if the vehicle is loaded. I'd say it probably would be better with an auto transmission as the torque converter would probably help with the off-boost shortcomings. Specific to the R2.8, lots of poor reports of durability, but the drivability thing is more universal for the newer small diesels. I wouldn't recommend an R2.8, but as a Toyota-based comparison:
The new 70 series is sold here with 2 engine/transmission combos:
1) VDJ7# - 1VD-FTV engine and H152 manual transmission, 151kw at 3400 rpm and 430nm from 1200-3200 rpm.
2) GDJ7# - I'm assuming this will be the model designation, 1GD-FTV engine and AC60 auto transmission, 150 kw at 3400 rpm and 500 nm from 1600-2800 rpm.

Which do you think will be more 'drivable' with everything else being equal?

The other interesting thing is, the 1VD used slightly less fuel in a towing test of the same weight as the 1GD. There isn't really a replacement for displacement.

I’m well aware the FTE came in a 100/105, that the point I was making. I’m in the US, you’re in Australia. We don’t have ooldes of anything FTE here
