What Do You Think?

5.4 triton in a 78 bronco?good idea?bad idea?

all opinions accepted on this subject.

 

[davids78bronco]

Myself, I like the idea... I always like ideas that entertain thought on different powerplants and drivetrains in any vehicle. But, I see several problems with the 5.4L idea - all new mounts (all of them), complete custom exhaust, everything is run on a computer, which means the axles need the appropriate sensors (whatever those may be), you won't be able to use the stock trans or Tcase, and might not even get to use the stock drivelines (even if they were modified to fit the TCase). Now, that's not to say it isn't possible... shoot, if a couple guys can drop in a 5.0L and a solid rear axle in a Focus, then this swap is do-able too. But it will, most likely, be down for work and modifications, alot longer than you might think

And without a supercharger of some kind, I don't think it'll have enough power to move a 5500lb truck with any ease, which would also mean the 5.4's transmission would need some beefing too

 

[BRONCOGIRL78]

yeah I was told it was a bad idea as far as the time it would be down,I didn't know about all the other stuff.

what if a rolled overed truck was bought from the insurance co. that someone's husband rolled with 58,000 miles on it?

you don't think a 5.4 would be enuff for a bronco?the rolled truck moved alot better than my bronco.

I wouldn't be doing the work anyway.lol

If you have the opportunity to buy an insurance salvage pickup, that has all the powertrain and drivetrain intact, and buy it for swapping to your Bronco, would you PLEASE document every last bit of it? I talk, chat, email with several guys that all talk about swaps like this - everything from a Caddy engine, to a PSD, and a 5.4L has been mentioned a couple times. None of us have the money, or facilities, to take on a project like that, but if you decide to do it, you'd have no idea how invaluable any, and all, of the information you can gather about the swap, would be to us. For a few reasons - mostly for proof that it can/has been done, it can be a reasonable, and fuel efficient swap, and while it may not have the torque of a 400, it would certainly outshine a 351M

Side bonus is, you can sell your engine, trans, Tcase, to help offset the cost of the donor pickup

If you were to do that and be willing to fully document it here at broncozone.com with pictures and technical information I might be able to get you some big discounts at Bronco Graveyard for any parts you might need that they carry. There probably aren't too many things but there may be some small items like a driveshaft or ****** that they could supply.

I like the idea. Having a donor vehicle is the only way to go on a swap that complicated, though. If it's a very late model truck (98 or 99 up) the PATS anti-theft system will be a pain to wire in. The engine will not start without it, and I know of no way to defeat it. That means the late model steering column will probably have to be transplanted. The swap shouldn't cost a lot, minus the donor, but it will be a ton of work and headaches. Stock up on beer and asprin. /emoticons/[email protected] 2x" width="20" height="20" />

 

[Guest_broncogirl78]

it's not a done deal but we have the oppurtunity to buy the truck and I'm looking at triing to keep my husband crazy.I don't know it's just an idea.

thank you for all your input.

 

[gobucs1]

So any new news on this?

Hey Broncogirl,

You've probably already moved ahead with this, but here's my 2 cents anyway.

Just because it can be done doesn't mean it should. 78/79 Broncos drivetrains are so tough and reliable I can't imagine why you would want to complicate things. With such a simple vehicle to work on and maintain, why make it complicated? I guarantee you that even with an affordable donor vehicle, it will cost at least twice what you think. Unless you can do it all yourself, the money you will spend on such a swap could put a 460 in there with almost no headaches and only a fraction of the downtime. Then power is not a problem. Mileage will not be as good as with the 5.4 Triton, but who owns a big Bronco for mileage reasons?

Sorry for the doom and gloom. I've learned lessons like this the hard way.

I'm not agreeing with this philosophy. Just because it might not be the best idea for this, or any other truck, doesn't mean it shouldn't be done. I've done this in the past too... discouraging someone from trying an idea, but I can appreciate someone thinking outside the box. If they wanted to drop in a toyota 20R engine in it, then go for it. Just because it might be a waste of time, effort and money to you and me, doesn't mean it would be to someone else

 

[4xfan78]

i agree with davids comment. Tyr it, if it works maybe more of us could do it. I have heard that a navigator has a better 5.4, but if you can get that one cheap enough get it and let us know how it does.

 

[Quint]

I'm doing almost exactly what you're discussing, and yes it's a lot of work.

Do I think its a good idea???Sure.Would it be somethin I wanna do?No I'm to old school and don't have a whole lot of faith in modern electronics.

 

[Wliebhard]

Sounds cool. You may want to talk to factory 5 racing. If they have a kit to put a 4.6 (or is it 4.8??) modular into thier kit, then they have worked out the major problems I'm seeing discussed here. I can't imagine a 5.4 modular being that much differnt (anti theft sensors, ect...) than a 4.6( 4.8??). Also have you thought about a V-10? I've been tossing that one around for a while.

 

[Wliebhard]

One more thing, IF you decide to do this, a Linc. Navigator is WAY better. It uses a 3 valce head vs. 2v and makes alot more usable power, plus go fast goodies work better on the navigator. In the Mustang world, Navigator motors are all the rage in swaps. (now your four cents richer!)

 

[DSal]

Yep the new navigator motors are 3v, older models are 4v and are sick. We've popped several in my groups cobras. I couldn't even venture to guess how it'll hold up to the stress of 4 wheelin.... either way, good luck if you continue down this road /emoticons/[email protected] 2x" width="20" height="20" /> ...new cobra motor's can handle 600hp with bolt on changes (but the engine alone will cost more than several 79 broncos).

[highboy73]

that is a project that is going to take awhile

 

[Quint]

MY BRONCO IS NOW ON THE ROAD POWERED BY A 2004 5.4L TRITON. SEE VIDEO CLIPS AT:

I've proven it can be done, but it's up to the individual whether they're willing to put forth the effort. This was much more than your average engine/tranny swap.

Awsome!! I love to see a project get done with that good a result, new technology is so efficient, I'm old school too but you always need to keep an open mind, I'm looking for a fuel inj. 460 for my 76 supercab, you can't beat factory performance & economy! great job! Kudos to you!
