How to Fuel Inject Your Willys L134 With a Holley Sniper

- This is an extremely detailed installation of the new Holley Sniper Autolite 1100 onto my Willys Jeep. I compare the differences between the Carter WO, YF and Sniper. Then showcase my adapter, linkages, fuel system, and wiring to make it a turn-key setup. It's a pretty straightforward install.
A complete parts list for my setup is shown at the end of the video. As this is probably the first Sniper 1100 ever installed on an L134, I was flying blind without any reference. There could be better options for adaptation - but this is what I came up with.

That little metal "V" is a turbulence inducing device. Those old engines (flat head 4 bangers), had small valves and small ports in order to keep air velocity up in a low reving engine. In areas of the intake that had large area, (i.e. the intake plenum), air velocity slowed, causing the fuel to settle or "pool". That device was intended to induce "swirl" or "turbulence" into the incoming fuel and air mixture, thoroughly mixing fuel and air, so all cylinders got a balanced fuel air mixture, (no Lean and no Rich cylinders).
Also known as a diffuser
Wow. This was the best Vlog ever! Fuel Injection on an old flat fender Jeep! It doesn't get any cooler! Nice job on the install and absolutely perfect on describing every step of the way! 10 out of 10. Thank you for sharing!
fun fact in case you or other people dont know AN is just the number in 16ths of an inch, so 6an is just 6/16ths or 3/8ths thats why it fits the best for a tight seal
That sure is going to help when crawling up at wierd angles , no more fuel fails and having to restart 👍👍🇺🇸
Edit: Holley EFI adapter kits are finally available, and you can purchase on my website: www.turnandburnout.com
Definitely interested for my 3B with the F head motor.
I'd love one for my '51 CJ3A Project.
Great job. Do you have any of the adapters for sale yet? Thanks
For some reason I can't email your Gmail from here sir. I would like to know about the adapters buddy. Thank you for your videos.
@@tommyhare1029 Hey Tom, please email me at turnandburncontact@gmail.com
I'll upload a full driving video with mpg tests, extreme inclines, etc by next week.
je regarde souvent ta jeep avec bam bam et ses amies dans le moab. c'est du bon travail que tu fais et que tu as fait sur ta jeep. le seul soucis avec les carburateurs c'est qu'ils déjaugent dans les pentes. l'essence coule et risque de faire un départ de feu. je viens de mettre en ligne sur mon groupe jeep en France ton montage avec ce kit fantastique. ma jeep dispose d'un V6 ford avec une injection ford EFI mais sans le module de contrôle, c'est parfait pour le tout terrain hard. bien à toi depuis la Nouvelle Calédonie.
That was I was thinking, any thoughts after the swap on throttle response, engine run, MPG, etc? Thanks! Good detailed video!
How's it compare to the 2 barrel carb ?
Just a fun fact about AN sizing: The dash number is supposed to represent the numerator out of 16. So -6 AN is supposed to have an ID of 6/16 inches.
Dude. You are one knowledgeable young man. We’ll spoken and Informative…. You’re going places. I’m definitely subscribing to your channel 👍🏻
This is great video. Wasn’t thinking of putting a Sniper on the L-Head but I have a CJ3b with a F-Head. Like how you showed the sniper on that. Definitely have been waiting for a video like this
I’ve been waiting for someone to do this. Very helpful. I’ve got a CJ3B and the sniper kit is on my bucket list for it. Great job!
this video is awesome and the engine sounds good. I will definitely use this for reference also thanks for the parts list at the end that's super nice
thank you for the videos you make I always learn something
This is very cool. Its a little bit of an investment at $850, but well worth it in the long run for improved drivability, no stalling, etc. Nice job on the installation...super fresh!
Ya just having the O2 sensor so the motor has a way of knowing what's actually going on in the cylinders and it has the coolant temp sensor too which is cool
Very cool. Definitely something to consider for my CJ5
Some very good commonsense advice here. Thanks mate.
I'm seriously considering getting one for my 300 inline 6 pickup. This video is helpful for me.
Awesome video, packed with info. Great job!
I really like these types of tech vids. I really think it would be super trick to put a full COP, MPFI, sequential fire. Yes, I am talking about full on Crank Position, and Cam Position, Coil per spark plug. I think that would be so trick!! But I like how you are showing how simple it is. Awsome stuff.
I agree!
That's awesome man. I have 2 M38A1s. I may try this on one of them
Awesome 👏
Thank you for sharing this amazing video 👍
Keep up the great work and I’ll see you in the next one 👌
One word to describe you- AWESOME
Keep going👍👌🙏🙏🙏
Fantastic video I just installed my sniper on my 64 international I have a bout 400 miles on it now and have had very minimal issues. I as well had to replace my alternator cause my one on installation wasn’t enough
What motor does your international have I have a 54 r 110 pickup with the blue diamond, but it's still 6 volt.
This is a great video. Thank you for sharing. Impressed!
Best sniper video out there. Great video
I have a sniper on my 45 cj2a but I put a Ford 2.3 pinto engine in it. Twice the power, twice the fun.
Excellent presentation!
I've a 134 f. Seems far more compatible for, between the bolt up issue & the exhaust heat. In all honesty though, you lost me when ya broke out that little computer screen. Mechanical advance, filing points, that's all I know. That fuel
pump/filter set up--
very nice!
Mostly typing to commend you on such a well laid out & put together video.
...oh one last, at the end, ya mentioned carrying a spare?
Memory serves me, think I might have an old Carter under the seat. If we ever meet up on the trail, ya need it, it's yours.
All jest aside good job!
John
Great presentation! Thanks.
Great video, I have a 1942 Land Liz willys mb and I would not put a Sniper on my jeep but would gladly install it on my UAZ 469 from 1978.
Wonder what fuel mileage you are going to get?
The fuel going past that inverted V would cool as the carb as the fuel went by as it would be changing state from a liquid to a vapor and may cool the carb. Just a thought and it would be interesting to know. May assist in atomizing the fuel to each cylinder. Someone knows.
fantastic job.thank you
Read up on the GM HEI module. I've done a conversion locking out the original distributor, and using the original points, (very little current) to trigger the module.
7 pin module for electronic conversion. Megasquirt documentation has a good write up on how they work.
Good video. Look forward to hearing what your mileage is.
great video!
Perfectly explained👾
Hello
About a year ago I was looking to install the sniper on my CJV35 with the l134 engine . I am running dual fuel tanks and the cost of two pumps with the price of the sniper changed my mind. Researching the install I looked at the linkage for options also the mounting . Great solution on those two and tips on using the stock tank. Thanks
Mitch
Use a simple fuel transfer setup that’s not built for pressure?
@@tedcarl5382 Hi Ted . A simple transfer (low pressure electric fuel pump) is 60.00 usd and the price of pipes , hoses and wiring not bad . But the Holley 887.95 ,58psi pump 150.00 and Turn n Burn adapter and linkage kit 299.00 or try to make your own . The cost of this project is why I decided not to install this unit .
Mitch
Great Video!
This is awesome!
Great video.
31:10 I just fixed this EXACT issue on my Megasquirt injected Datsun. Thankfully, it was just swapping fittings, but I wish I'd know what from the beginning. :/
Going to rewatch the part about the distributer; I'm considering this system on my F head on a stock m38a1 jeep. I want to keep the 24v system, but have a more reliable setup for cold starting, ease of use.
Some kind of battery equalizer I believe would be required as there isn't exactly a dual voltage alternator around for these.
Now if only I understood gas engines better. The install looks fairly straightforward but I worry I'll get in a situation where I have to replace military 24v parts with civilian 12v parts to really make it all mesh.
On my older Submarine build videos I actually converted a sealed 24V distributor with a rare and expensive 12V coil sold on eBay overseas. But you'll have the problems of all the special electrical boxes and plugs. I personally wouldn't do this swap on an M38A1 with all its stock style wiring, it's just too unique. That's why 2 Jeeps are always better than 1.
Good presentation. I'm not sure if you know this, but you didn't necessarily need to fabricate an adapter, if you could find the other type of Willys L134 intake manifold used with big-throat Carter carbs such as the WA and the YF. The small-throat WO carb was used on 4WD Jeeps; the big-throat version went on 2WD Willys Wagons and Jeepsters. The throttle linkage is different, because on the big-throat version, the two carb studs are located side-to-side, while for the small-throat version they are front-and-back. Either version bolts to the same exhaust manifold.
On the sniper....how did you seal it from the air filter and the top of the carburetor?
Great video, I want to do this to mine. Did you gain any power?
will this function on the later model CJ5 151 engine?
Intake manifold may have used a rubber pipe so what is look like at 7:25 plz answer
Thanks for putting together these videos - I might try this mod. It would be great to see how you've wired the Willy's end to end. I noticed none of the traditional fuse blocks are mounted to your fender.
My Jeep has so much custom wiring that it wouldn't be a good video. Just follow the Holley instructions, and you'll be good to go.
Any idea where I can find an l134. I need to pull mine out to have the crank turned. I'd rather build one and just swap. I also want to put the sniper on. Any way to get another one of those adaptors made?
I have added a 2 barrel holley sniper to my dodge weapons carrier. Make sure you have good suppressed ignition leads as sniper will have problems with interference.
What does it to your dodge fuel consumption?
@@rockymountain5222 it is a bit better but where it really helps is cold starts and being smooth. No flat spots.
Nice vid Nick. It will interesting to see how it holds up.
I’d like to know what the AFR is at a constant speed going down the street. Great video.
You can tune it, but out of the box around 13.5
first off love your video. one area of concern is the O2 sensor which my 1952 Willys doesn't have. this kit comes with O2 sensor and all the electronic harness. will this kit incorporate into my '52 Willys when the O2 sensor is not connected?
You have to install the 02 sensor. It's what the computer uses to create the air/fuel mixture tune
Congratulations. major changes to the Jeep Family are a major plus which does include what you are doing in this thread. I am wondering if any of your work could be transferred to a later model CJ5. Is it ok that I send information concerning a project I am considering involving the Holley Sniper? Great Job and a major step in keeping the older Jeeps alive and well in a modern demanding world. My project will be using the Sniper system on a 4 cylinder CJ5 1980 151 GM HEI using the emissions systems in their entirety. Question: Is the Holley Sniper Smog and emission approved and do you see any problems involving the 4 cal. engine. Most changes involving the Sniper have been involving the six cylinder engines.
May I ask if this jeep still has same holley sniper kit operating the Jeep ??
Takes a year or less to remove from malfunction & haven't found a sniper operating after 1-yr
Yes I've been running the Sniper for years. I'll never go back to carb
will this unit work on a 1970 DJ5A with the 4 cylinder engine?
I'll have the F134 adapter finished in a few weeks. It'll be on my website
Actualmente como funcionar tu willys con ese nuevo sistema de carburación?
It runs excellent
mantap sklilnya sangat bermanfaat ya kwan
Did you use the Pertronix Ignitor II by autolite for the distibutor?
No I used a solid state
Some LS coils would probably make it run better than the distributor I think it would be worth trying since you can get them pretty cheap if there is not much else you have to buy but I think you would need a crank signal
And then you go over it all
I believe your IAC POS % should be between 1 and 6 when the engine is up to temp.
Good eye, I actually fixed it after posting this video.
I looked on Holleys site and they do not list one for the engine. Which one did you purchase?
Autolite 1100. It's actually meant for the inline 6 Mustang. Full parts list at the end of my Sniper install video
Does this engine have hardened valve seats? I assume you’re not using a lead additive in your gas.
Just curious because I wanna do the same thing but have no studies on leaded vs unleaded on these engines.
Lead will damage the O2 sensors over time is what I’m told
Yes it does. I run pump gas
Cool setup. External pumps suck. I would recommend you convert to an in-tank.
I know you take that jeep to some incredible trails, out in the middle of nowhere, how are you going to diagnose this thing if it acts up?
How many times did that Carter let you down? Maybe I'm wrong, but out in the middle of a trail, I'll take my Carter, & points ignition. Hard to beat
the simplicity of that system.
Process of elimination. Does the fuel pump work? How's the fuel pressure? 02? Etc. Carter has let me down at least a dozen times on my various Jeeps. Linkage prone to falling apart, fuel leaks, stuck floats, etc.
@@TurnNBurn I wonder if the brand new Carter that are made from Joe's Motorpool Parts, would of solved the problem. Thanks for the reply.
@@dinofalabrino8522 Nick splurged for a second backup carb. keep in mind you could carry the original carter carburetor and components to swap back. it wouldn't take long. thats an idea for someone that does not want to spend on two holly efi units. keep us posted on your tests nick. this might be the way to go for me.
I just did a timed swap from EFI back to carb... will be included in the next video!
The ECM is fixed on the Trottle body?
Yes
Would this work on an m38a1? The carb is in a different position more at the top of the engine
I'll have an F134 engine adapter available in a month or two
@@TurnNBurn I've got your vids on alert. I'll keep an eye out
You think this will Work on a 1969 600ccm 2 cylinder 2 stroke engine?
And thank you for your Video Its a good explanation and i think i buy one for my Audi
Propane 👌
what is the part number of your fan belt? Looks narrower than the 5/8" belt
It is
Do you sell the blueprint for the adapter
well,i wonder if it exist a version of this TBI for a 1 cylinder engine! ?
I don't see why this couldn't work on a 1 cylinder. Any extra fuel just goes into the return line
@@TurnNBurn hummm maybe ,,i would certainly have tried it on my Yamaha Rhino 2006 that is carburated.i am looking for a cheap way to install EFI on it .i used to work on cars and trucks injected,i have seen the "evolution" and if yours is well tune your engine and driving experience will be great ! leu us know !
How did you actually get one? I tried to by the Autolite 1100 Sniper for my Land Rover Series 3 for months and it's been on indefinite backorder.
I ordered in March and just received last week.
It would be intresting to see a fuel injected 2.25.
I put a modern electronic ignition on mine and it allready runs a lot better.
It also improved the fuel economy when running a little more timing .
@@rickz9495 North America Overland does the Autolite 1100 Sniper on their builds now. I'm in Kenya and the cost of importing one is prohibitive. I have a Weber 34ICH right now that runs beautifully.
@@upscaleshacki have the same carb, it runs great and starts great. the only reason i would want fuel injection is for beter fuel economy.
So it would be intresting to see a long term review on this Jeep.
But i think it would be pointless to upgrade to fuel injection with a points ignition or a cheap electronic ignition. My fuel economy and part throtle performance improved greatly with my new fancy ignition(123 ignition bluetooth distributor).
And i agree on the cost of this setup.
I think it would cost me around €1500 with al the extra parts. I can buy a lot of fuel for that kind of money.
Can I install it in a Dodge 318 engine? ..... in order to save Fuel.
Holley offers many different sizes
Datsun L20 , L18 or Z24 maybe ?
install the fueltech FT 600.. you can make your own map
What starter are you using?
I have a CJ5 style bellhousing and ring gear to run the Toyota starter. Lots of info on earlycj5 forum
Definitely do an update video later on your fuel economy numbers. Very curious about that aspect.
V shaped device appears to be a diffuser/ heat shunt
Great job. Do you have any of the adapters for sale yet? Thanks
I'm doing a small run of 20 next week. They'll be up for sale in a couple weeks. Email me or message on Instagram if you'd like to buy one
@@TurnNBurn Yes sir, check your email from this page please sir. Thank you for the time it takes to make your videos.
What did u do about the heat riser?
Welded it in place on the inside, and JB welded around the rod to prevent exhaust leaks.
@@TurnNBurn I have contemplated megasquirting a 48 cj2a, however you made such an amazing blue print I can't but follow you lead. So why wouldn't you remove the whole heat riser guts? And by welded in place I assume in the position as if the vehicle was fully warmed up?
Hi did you happen to make the adapter for sale yet?
I just established the business this week, website will be up soon. Adapter design is mostly finished, just finalizing a few minor details to make a seamless install
@@TurnNBurn Great, please let me know what the website address is and when you are selling them. Thank you
Was it worth the costs and trouble?
Absolutely
Does your buddy sell the adapters?
No
I’m late to the party… hopefully someone will see my comment and help an older dude out. (I turn 67 this month lol). Will this set up work on my ‘89 yj with a 4.2 liter engine? Or would there be a better alternative? Thanks! 😊
How much horsepower might this add?
Probably none, just makes it run perfectly in all elevations and climates.
👍
👍👍
anything like a spider on my Jimmy.?
Is this 6 volt or 12 volt?
12V
Run some shielding on them wires
Note that a 12v system is required for this.
Thanks mine is still 6V on my international pickup didn't really want to convert
How much?
You need to put links on the stuff you have .example the filters and were you find them.
All info is at the end of the video
@@TurnNBurn thxs. I just ordered the sniper from my Jeep and I need to try to figure out where I can get that adapter that raises it up off of the intake manifold
@@TurnNBurn The adapter your buddy made on the autocad is what I am after. I did not see that on the list.
It's just a couple flanges with tubing. You can make it with a grinder and welder.
How to order and how much
www.turnandburnout.com for the adapter kit
Would this work on a VW bug?
Yep
How much this
I have watched this and it makes me want to EFI my 1980 CJ5 2.5L GM 151cu inch. Thee video gives on a very good overall perspective of the changes and adaption needs. I have watched Turn&Burn build this Jeep. I really like how he approaches and creates adaptive solutions. Video is one to save and Talk To Holley.
Отличная работа! Но карбюратор надежнее.
way you do the
It wouldn't be difficult to lock up the distributor shaft, use the internal reluctor sensor & module to trigger the Sniper & then use another HEI module to fire your existing coil. Your distributor is in terrible condition, with all 4 connections on the HEI module corroded.
Would still need a working distributor shaft to run the oil pump
@@TurnNBurn Well that goes without saying. I was referring to locking the top & bottom distributor shafts together so that the ignition timing can be controlled by the Sniper. The set-up screen actually shows a setting for " Magnetic Distributor" which could connect directly to the reluctor trigger. Then the existing ignition module could be moved somewhere dry & fire your existing coil. So then you could have electronic timing for no extra cost. PLEASE overhaul that distributor anyway as it is a disgrace to the rest of the vehicle.
You will Probably find out if you disconnect the battery you got to go through that whole system to read so it will re-calibrate itself for about 2 miles after you disconnect the battery
The tune is saved to the internal computer hard drive. It doesn't disappear if the battery is disconnected
