Modern Holley EFI on an old Bronco 2. Increases power & drivability and pays for itself with MPG's!

- This 1984 Bronco II was put out to pasture and forgotten about.
But, I rescued it and in a previous video gave it a new life with a carburetor swap. Ditching the antiquated EFI. Holley saw that video and wanted to prove that upgrading to a modern EFI is just as easy as reverting backwards to a carburetor.
Today, we install a Holley Sniper EFI 2300 for under $1400. Which seems like a lot of money until you add up the cost of a DuraSpark distributor, carburetor, and ignition module. For just about the same money, you can have drivability, tunability and fuel economy at your fingertips. An added bonus is the computer timing control will increase power and efficiency across the board. We’re betting we nearly double the fuel efficiency of the Bronco, paying for the upgrade within a few years.

I feel I watched this somewhere already. Stuff happens, not every video can be perfect. Here for this one and the next one. 👍
Thanks for the support. I'm still working out many kinks.
Not that losing footage is ever convenient, but if it was going to happen this was the best one to happen with since JR was recording it too.
I know its a couple of years late, but thought I'd chime in about the 02 sensor and cat. If you're still running the computer, I would think you'd still want those parts. Walker sells a free flow cat which has always worked great on my vehicles, and you can always weld a 02 bung anywhere in the pipe before the cat. I had a 86 B2, I think the 02 bung was on the cat, cant remember. Had a Mountain Driveline rear drive line with full size Bronco U joints, 6" Skyjacker Class ll lift, welded 7.5" rear diff, and Rancho 9000 shocks with on board air. Was a beast!!! Oh yeah, I also redid the entire cooling system, deleted the clutch fan and installed a FF-Dynamics 3800 cfm electric fan. This was my best upgrade because it not only restored my power from the added weight and oversized tires, but I had more power and torque than stock. My mpg was somewhere in the 20s. I depended on this rig with my life, very very dependable, even at 308,000 miles.
If you still have this rig, check out some of the vendors I mentioned, they were very affordable and reliable. I really do like how you're going about restoring this B2, these things are literally little tractors that can go anywhere.....
EDIT - LOL, right after I wrote this, I watched how you added the straight pipe with the 02 bung! Friggen awesome!!
Although you're still working out the videography kinks, you've mastered the art of the cliffhanger! Let's see her fire up!
Nice to see that JR let's you manage your videos....some RUclipsrs can't help themselves when in other's videos and try to "take over".
Glad you weren't involved in that Ford accident. Hope they are all ok.
So when do we get to see/hear the Lil Juice run? Haha.
If all goes as planned, I'll squeeze the juice on Monday.
Holley overnighted the coil driver today. It should be here tomorrow. But I'm working nights all weekend.
Interesting build! I have an '88 with factory efi 2.9. I'm going to keep up with this build. SUBSCRIBED!
Just got the same rig, it’s a little rough right now but I need to make a daily out of it. Not sure if this kind of upgrade or restoring factory parts is a better solution. What did you go with?
1984 bronco II had a 2.8 with a carb from factory. and yes they things have become made out of gold lately
You guys are the best! Even though you lost some footage it's still very enjoyable!
Thank you, the stress level was pretty high. But the video came out ok.
On this episode of WatchJRCameo... Good stuff, Josh.
G day, mate.
These Holley EFI units would saved my old vehicles from the wrecker.
Enjoying your channel Josh.
I believe that 2.8 liter V6 may not be a powerhouse but if I remember correctly that's a Mazda/Ford joint venture engine and although not powerful it is very smooth.
Had 1 in a '93 ford probe gt and it was quick and robust until the timing belt broke at 260,xxx miles.
The 2.8L Cologne V-6 is a Ford of Germany engine that is actually an American design dating to the late 50's/early 60's as an industrial engine. Initially a V4 layout engine, it morphed into a V6 layout because of larger Ford of Germany vehicles being produced. It's initial introduction to the U.S. market was in the 1972 Lincoln-Mercury imported Capri in a 2600cc V6 size(with siamesed exhaust ports alluding to it's V4 architecture). In 1974 the V6 was enlarged to 2800cc with individual exhaust ports for each cylinder exhaust valve for the American market.
I had a 1984 Ford Ranger 2.8/4 speed standard 4 wd purchased new. They actually came from factory with a 2 barrel carb. I don’t think they received any type of efi until late 80’s I may be wrong.
I had an 84 Bronco II, purchased in 85. The engine was the 2.8 V6, German-Cologne factory motor. 2 barrel, Ford EEC IV computer controlled feedback carb. Solid lifter cam which does require periodic valve clearance checks. That all went out the window in 86 when they introduced the 2.9 V6 with EFI and hydraulic lifters. My problem spots on that engine was a constantly clogged EGR valve and a propensity of the motor stalling out everytime it was damp outside. This was caused by dampness buildup within the ford distributor. They were aware of this and their solution was a small plastic umbrella cap mounted on top of, and outside, on the distributor cap. She was a nice little off road trail rider.
I had one back in the late 90's and the Achilles heel was always the distributor.
Modifying the Bronco is well worth the Time and money. What else you going to do if we are not preserving our heritage.
How Much Did The New EFI Carb Cost & What Should Your MPG Be With the New Holey I Have A 1984 Bronco 2 & i Hope You Do More To It to make it full on Off Road Ready But Not CRAZY Just Enough To Not Get Stuck Out Some Where ,Like Lockers Maybe A Lift & The Best Size & Kind of Tires ,Thank You Guy's For What You Have Done So Far , We are on A Budget
Really, really looking forward to seeing the B2 run with modern EFI.
LOL - We got Rob Pitts over here! Need another SEMA WatchJRGo & Rob Pitts collaboration.
I love the Bronco II's and installing the Sniper is the best thing for it. Following to see it run!
I didn't know you had a channel! I'm starting out also and I was warned about the gopro magic delete....sorry about your footage.
I use to have one of these Bronco IIs and I loved it.
I wish you luck with your channel and look forward to your new videos
These kits are great. I had my students install a quadrajet replacement on our mascot parade car. So much more reliable and smooth than the worn out quadrajet. Enjoy the upgrade as it continues to learn and get better.
Fantastic upgtrade
Sorry for the dumb question but aren't you guys were brothers or step brothers? Just curious since you've introduced him as your friend in a couple of videos. Keep the vids coming! I've had my gopro eat my files too, btw. I lost some home runs on camera and was pretty upset about it.
Love this video and seeing that sub count jump! Having good friends like JR makes all the difference! Question - will you keep the lil juicer or sell it? It's fun to watch the build, but if you can get Healey parts, I mean money, out of it....
Definitely correct on used car prices.
Lil'juice seems like a great name for it :)
Hope to see more vids from it. These lil trucks are awesome to work on and the amount of stuff you can do to them. You have a VERY capable little rig that goes anywhere and can turns on a DIME.
And F the haters that say these are unsafe and are prone to falling over. It has the same potential to tip over as a lot of cars at high speed. It is no worse then a bunch of other trucks
Thanks for this really going to help my out w my 85.
I had an 84 v6. It is an electronic carb with timing controlled by computer stock. Yours has an older distributor to run carb which was correct. Should get stock distributor to integrate into Holley computer
That's what I do not like about GoPros, they can be really glitchy and sensitive to what memory card you use. Keep up with the good work, enjoying the channel!
Hey Josh! Awesome content. Hope you are well. Quick question sir, do you think this same holley sniper system will work on a 87 bronco 2 with the 2.9? Im having problems with the stock EFI, the injectors dont want to fire. I already found a 2 barrel carb intake for the 2.9 btw Thank you sir. Keep up the great work!
Ok so on a serious note. I'm glad you have your own channel. I hope to see more on your Trailblazer on this Channel. I have a Trailblazer myself. Mine has the 4.2L in the EXT. I really like it but the engine has a misfire and possibly a blown head gasket. It's gonna have to be rebuilt or replaced. If you have any suggestions please let me know. Thanks
Thanks Ray! My TBSS is coming soon, I have an aluminum radiator for it and I'd like to address a persistent exhaust leak though the cheap long tube headers. Then I'm planning on putting my fox body on a trailer and using the TBSS to tow it to the track in an attempt to run low 12's with both.
The 4.2 is a love or hate engine. Luckily they are cheap and can be found at nearly every salvage yard. Knowing that it's cheaper to replace than rebuild them, I would definitely swap it with a known good engine if you run into issues.
Richard Holdener and Hot Rod Garage both just made 420hp with a small turbo, a set of injectors and HPTuners. They are planning on a 600hp build with headwork and a cam.
@@TheFracturedRooster That's awesome. Thanks for the info also. I'll look them up
The original electric carburetors were good and got good mileage if smog pump and other emissions were functional and intact. 12 mpg is a sign of an older system running in limp mode.. so to speak
Hell yeah keep up the great work!
Next video, headliner install?
Hi Josh. Any Foxbody content coming? I have a supercharged 93 Cobra. 🦊🐍🤘
Yessir! I put the car in storage. But I have some interior trim and a new radiator for it. I'll dig it out and do some big stinky burnouts with it.
@@TheFracturedRooster Yay! I’m running a Champion radiator with a Ford Contour electric radiator fans. 🤘
Give me a liter of cola! A liter of cola, it’s for a cop.
Lil Juice Bronco 😂
I took a '96 4.9L distributor and hollowed out cyl1 spark plug wire hole and epoxied a hall sensor in and a magnet on the rotor. EFI'd a '78! (next is a 36-1 wheel up front using a '96 harmonic)
Annnnnnnnnddddd! Used a Wasted Spark Coil from a Chrysler Mini Van! totally ditch the distributor idea and it now only drives the oil pump and sensors.
Can the Holley Sniper do a similar thing? If I remember right, needed a cyl1 sensor for Cam Sync...
That's pretty slick. Once you understand the basics it's pretty easy to fab crank triggers and sensors.
I think the holley will work in your situation. But you'd probably also need a coil driver to amplify the signal.
@@TheFracturedRooster You probably has a VR (Variable Reluctance) thingie and needs the amplifier/signal conditioner, aka Coil Driver. You can probably do something similar and ditch the distributor and go with COP's or Wasted Spark. my '96 distributor uses a Hall Sensor and puts out a digital signal.
Ill take the Holley
I've been thinking about this kit for my 84 and the CFI unit from the 3.8 of the mid 80s aswell. My Bronco II has a build date of Sept. 83 and has the 17 gallon tank. I was wondering if yours had the 23 gallon or the 17 gallon?
Another question if I may. What was your mileage with the Sniper? The 3.4 S-10 (bigger version of the 2.8) i'm getting about 15-16mpg with the 91 EFI system. I'm not looking specifically for an improvement, just not a loss. There's a guy on S-10 forum that did this swap and his fuel economy never got over 10mpg. That's worse than my truck got with the factory carburetor. Dude is pretty smart on cars, so he was stumped. I think his system has a bad 02 sensor or something and he's getting the wrong readings to the unit. But as much as this costs, I'm really wanting to check boxes. Thank you!!
Why did the guy drive head on into traffic? Old, drugs/alcohol, texting?
My 89 Bronco 2 has a hole in the floor to access the fuel pump without dropping the tank.
OMG, so your B2 was an EFI model and you pulled that out to put in the Holly? Is it easy to install or do you need a degree to install? I may have till consider this for my 87!!
The EFI was already removed from my B2. The EFI was more of an electronic carburetor oy used in the 84/85 years. Your 87 should have a multiport setup which is pretty good.
you should get a doll made with a watch jr go t-shirt and have it in the back ground just keeping an eye on you. Don't even say anything about it just let it be there. watching.
OmG it’s J O S H!
What transmission does your bronco have and how did you hook it up to the carburetor?
C5 automatic. The only transmission interaction is through the kickdown rod. Which I attached with a holley bracket.
Woohoo first view
Thank you for the video! What was your before and after fuel mileage? I’m thinking of doing the same to my motorhome. We get about 6 mpg now and any improvement will help!
Really wish had more information on how you did the wiring… doing the same to my B2 but instructions are lacking how to connect with timing control to the durasparked 2.8L. You have any insight or wiring diagrams to share?
Forgot who’s video I was watching
what intake are you using to replace the lower and upper EFI intake manifold, to convert to the carb, and sniper EFI setup?
Ok great video but what did you use to convert to carb to begin with? I am wanting to do this with my bronco II
What was the MPG after the Holley Sniper install?
my stock 03 silverado gets me 10-11 mpg around the city .
now are the bronco II motors solid lifter cam still like capri and mustang II 2.8
I believe they are. That's why they all sound like typewriters.
84 Bronco II's didn't have efi. Had a motorcraft 2 bbl carb.
The truck didn't have any carb or ignition installed when I bought it. I didn't get to see how it worked. It came with parts to revert to a duraspark setup and a holley 2bbl carb. I followed the instructions below. They reference a computer controlling timing and mixture. Thats what I based my vocabulary on.
www.broncocorral.com/tech_library/duraspark-ignition-swap/
@@TheFracturedRooster That's the old EEC III system. Feedback carb and duraspark ignition. Very basic system.

So it's a Clementine?
So can we hear it run?
The broke dic garage?
Is this a 2.8 V6
I cant find one in my area for less then 7500 and that one is worse
I found a few in my area for $400 to $8000. The low end were obvious parts cars and the high end ones weren't exactly cream puffs. I think JR was right on the money with his assessment. I think Lil Juice should bring around $5k. I am debating ordering the quarter panels and sending it out for a Maaco style respray. I think I'll come out of it about even, since I'm into it so cheap.
Is this on a 2.8 v6?
Can you turbo charge that thing like a blow through
It's definitely possible. The sniper will handle boost.
@@TheFracturedRooster how mpg did the bronco manage to do
Two different days, same shirts. Hmmmmmm
Another obligatory comment for the entertainment and information
I'd rather have a 1st gen explorer 2 door. It's pretty much a bronco 2 just slightly longer
nice video review repair car lol
I daily a 1989 bronco 2, 2.9L v6, 5 speed manual, it's not practical at all.
THERE IS A WAY TO FIND FOOTAGE FROM A GOPRO 9.... RUclips WILL TELL YA HOW... IT SUCKS.... BUT THE GOPRO 9 ISN'T THE BEST....
Its the China Syndrome Jane Fonda truch, its way cool 😎
