Ladies and Gents.
I would like everyone’s opinion on what engine to swap into my newly acquired 1985 bronco. The v8 petrol sucks too much juice although it sounds great.
I’ve have big plans to use this to tour the country and family camping.
What is the top few engines for toughness and reliability for long distance touring and will also be a frequent daily too.
Bare in mind I’m totally open to options, my short list at the moment is as varied as 12ht , 2h turbo, Cummins 6bt or 4bt.

I want this to be special and want to be able to trust this thing anywhere.

All opinions welcome.

Cheers

Don't you want to import a shiny new one with a Sasquatch package? :) Unfortunately, no diesel option so not very practical for remote travel in Oz.

2021 Ford Bronco

Sorry, I have no suggestions regarding the engine but sounds like an interesting project! Hopefully you will update us as it progresses.

I wasn't aware, but apparently old Broncos have a lot of fans! :)

1979 Bronco sold for US$213K

Here's the engine that rebuilder opted for...might not be a good choice for your application though:

5 Liter V-8 Coyote Engine

Not an answer to your question but a question for you to consider before tipping a lot of coin in this direction
Do you think this vehicle is going to be suitable for your intended use longer term? Not a lot of family and storage capacity compared to other options that may require less modifications


I love Broncos by the way and it looks sweet

Thank you yes she’s a beauty. I here your comment, but when i look in the back it can’t have any less room than say a prado. They are so wide. I dunno I do here ya, just thinking it is a sizeable rear compartment actually has enough leg room for me in back and I’m 6”3.

Yeah fair enough if you are happy with it, just thought it was worth raising the point.

In a northern NSW campground I chanced upon a bloke who had his Nissan Patrol bonnet up. Looked pretty damn nice with its Walkinshaw V8 in there !!!!! He said rather smugly that it went "pretty well" .
Sounded awesome.

Walkinshaw in a 4wd, stupid! and it will use petrol at a fast rate too. How is that a good thing? It may jump from mountain to mountain and faster than a speeding bullet, BUT this is a Ford Bronco needing a fuel efficient engine.

Wasn't suggesting that it was a solution, just putting it there as one guy's idea of fun. Pulled a large caravan effortlessly, and actually quite economically ( about 15 he claimed) unless pushed. The V8 replaced the 3.0L diesel. Not sure what auto gearbox he used but it wasn't standard either.
Spent heaps but he loved it.

Sounds like an interesting project. Are you planning to do enough km's to make the reduced fuel consumption worthwhile? For the cost of an engine conversion you could buy a lot of extra fuel!

Yeah I definitely will, considering it will be used almost daily as well. Also reliability is a big one, especially out west around water

Maybe, Problem just beginning! I think it will be heavier, therefore, front end upgrade and any appropriate enhancement will be required.

Hi Cameron,

I don’t mean to burst your bubble, but I do not think Ford Bronco is a suitable vehicle for remote touring. Parts availability will be a big concern with an older, less popular vehicle like a Bronco, that plus someone qualified to do the repairs. No problem if you are capable of fixing it yourself, but spare parts could be an issue.

If you go ahead with your plans, I would think a Diesel engine would be a more suitable and economical engine. As to which “brand”, Cummins certainly have a good reputation. Maybe even a TTV8 from a Landcruiser, at least parts for the engine would not be as big a problem.

Yes that is a valid concern. I suppose one option would be to fork out for a hj61 with the 12ht. Rebuild it and trans. Of course you could possibly even just swap the axles out so you have more common parts. I’m not ok sure what’s stronger as far as diffs go.
I’m a huge fan of Toyota’s especially the older stuff. But I am a weirdo and like to be different. I’d love to keep this bronco for a long time. Much prettier than the poor old 60’s ??

Hi Cameron

If reliability is your main concern, Then a Isuzu 4bd1t would be my choice, the same as landrover used in the Army Defenders , As far as parts required, dont worry you wont need any!.

Any diesel you fit will require a lot of research for a decent gear box.

G.ood luck with the project


Cheers Axle.

Maybe check compliance issues/ requirements with an engineer
From recent enquiries I made about an engine swap you had to meet pollution requirements as to age of motor
Could have a substantial impact on your selection

Definitely best to check which engine/s the rego crowd will accept, long before anything else. If you choose one and fit it, then find rego won''t give a rego certificate. It can be a tad disappointing. Rego tech dept's can advise.

I would be staying away from the 2h turbo
In standard form they are a pig on fuel
And no power
A Cummins 4.5 common rail is the go too
Easily upped in power stakes
And towing wise they are awesome on fuel
6t gross easily get under 15ltrs on the hwy
Quiet too
Aeco are importing them
Based in Sydney
And have a YouTube channel
Really impressive power and torque but they are a heavy engine
12ht are getting Very expensive used
And factor in a 10g rebuild
The 4.5cummins is miles infront

To make it cost effective, you need to buy a wreck complete from the auction. I would suggest a hdfte in a hdj100, 5 speed auto etc. 10k plus for the wreck. Otherwise, the newer f150 comes with a 6 cyl diesel, a wreck there would be awsome

That’s the plan I reckon. Best way to go. I will most likely go with a 12ht 60 series and auto if I can get one at the right price. Love the old tractor sound of them.

Cummins 6BT coupled to an Allison is the choice of MANY OKA owners looking for power and reliability.
Most still get around 16L/100km at 5.5T.
