- Now you can give that old jeep of yours the drive-ability and performance benefits it deserves, with sniper bbd from Holley. And because I want You to know just how easy it is to get all those benefits and more out of your jeep, I’m going to take you step by step thru the complete install using our cj. It’s 84 cj7 with the original 258ci inline 6, sporting a carter BBD carb. Holley’s sniper bbd kit was designed for use on 1971-1986 jeep cj’s with this engine combo, and although you probably won’t see these numbers from your trusty inline 6, a pair of 100 pound per hour injectors, make sniper bbd more than capable of supporting up to 350 hp naturally aspirated.

I bought an 85 Cj7 that looks identical to that 84, and I'd love to have this Holley system on my Jeep, but it has the Howell throttle body already installed on it, and I can't find one mechanic who's worth a damn, or who even wants to work on it...I paid $3000 for it, drove it for 2 months, then found out the hard way that I had to rebuild or replace or upgrade everything save for the transmission, transfer case, and front differential, EVERYTHING ELSE I've had done...blew a head gasket 3 months ago, and I had the head and valves done by a shop that cannot get it to run without it backfiring and buckin like a rodeo horse, and there's no one else I can find who wants to work on it here in Los Banos, Calif..., Ive called at least a dozen shops I've got over $15,000 in it already and it just sits in my driveway....I'm so pissed off I can barely see straight....
Holy Crap!!! This is a Friggen GREAT Vid.. I wish this was available when I did mine... AWESOME!!!!!!
I was really excited, I thought I could use on my 53 Willy’s 4cycl.
This was a fantastic video. I'm sold on this system.
Wow, wish this was available when I did mine.....Nice!
That sender set up will fit some 67-72 Ford trucks. With the rear tank option. And possibly early Broncos.
Going to try this on my samurai with one of these efi systems. The stock 1.6 tbi on the tracker is getting to harder to find parts for, so I'm going to try this route.
Agree with the comments concerning the red-headed stepchild. the 87-90 YJs come with the same 4.2L engine, but the gas tank listed in this video doesn't fit (according to Holley when I spoke to them). So while the EFI system "should" work, we are stuck with the external fuel pump. Would love to see Holley put out some parts/videos for the YJ (we really need the help).
Also, what about the old computer and wiring harness? what of that can be removed?
You know, the YJ 4cyl were fuel injected. I see no reason why that fuel system couldn't be used to feed the Sniper install on a 4.2L. They had an in-tank fuel pump. Seems like all you would need to do is order all the factory fuel system components from the throttle body back to, and including the tank.
I want to get this for my 1990 YJ but I have a few concerns.
1) Are you guys working on getting this CARB compliant for California?
2) I plan on keeping my Pulse Tube for CA smog. Do you guys have any instructions on disconnecting pins no longer needed for the MCU?
3) Do you have a cover plate so I can remove the mechanical fuel pump?
Do you carry a 20 gal tank and pickup as well?
Please include our ugly stepchild ‘87-‘90 YJ’s with Carburetors and smog crap.
I am looking to put this on my 83 CJ7, I have stainless gas line from tank up frame to fuel pump, is it necessary to eliminate the gas line and run a new one?
Installed the Sniper EFI but my smog tubing is blocking the fuel inlet, which 90 degree fitting should i use in place of the one that came with the kit? Is it part number #98220berl?
Any issues running the sniper on straight 6s with un even intake manifold lengths. ?
Why are 1987-1990 4.2 liter Wranglers not included in the list?
The bolt patern match with Weber/solex 34 carburetors(93x46mm)?
Good good.. 👍👍👍
this says that it will work on a 1971 cj. But information floating around the web indicates that the 71 still implemented the 225 Ci "dauntless" engine, and the official word seems to be that these sniper kits may not work with the 225 being that it is an odd fire engine. So will it or wont it work with the 225 ci odd fire engines?
Hey, does this system work on a CJ 5 four cylinder as well?
I have a nissan patrol g60.. and am a machinist. Do you think i could make an adapter plate and adapt this in?
Will this work on my stock 258 4.2 liter inline six for a 1980 CJ5? Where would I put my temp sensor for the EFI?
Question for Holley or anyone... I have the 4.2L straight 6; Offenhauser dual plane intake with 4150 intake pattern (It's bored over and made about 210 on the dyno), I don't think I have a spot to put the temp gauge on the intake (I don't think coolant even runs through it), I was just going to put it at the front of the head, where the stock temp sensor is, but the stock sensor is much smaller than the one provided in the EFI kit. The stock sensor uses two wires that are the same gauge as the EFI sensor. Can I just use my stock temp sensor for the EFI system?
How do you connect to the fuse box? Via a connector and sleeve?
So does this mean I have to replace the fuel pump that’s new and already installed in my cj5 ?
if you want to install the bbd efi do you need the new fuel pump new distributor and all that? or can I just install the efi?
would this work on an xj 2.5 or do i need to find something else?
Flame thrower ignition runs full voltage to coil, Engine missing after EFI install?
that fuel pump would work in a original 79 cj7 fuel tank?
So there are 2 pressure regulators in this setup? One as part of the in tank module as described in the part description and also one on the efi itself...does that cause any issues? I thought one of the benefits of the Holley internal tank pump system(as described in the in tank pump spec (part #12-307) was that a return line wasn’t necessary because the return action happened inside the tank with that regulator...and if a return line isn’t necessary, would you just cap off the return side on the efi? Just wondering about effects of 2 regulators...
Two regulators are not needed, we just happen to be using a self-regulated pump on this build.
Will this work on the cj5 4cyl? Your getting this question by a lot of people and no answer
Is there something like this for a '73 VW Beetle?
Can you still pass smog with the new carburetor?
Everything I've read lately says the computer fails, and Holley doesn't have replacements available. Any truth to this?
I would love to do this to my '86 Eagle station wagon. But damn I only paid $300 for the car so to sadly not worth the $$ in my case.
Where is the return line run to?
Does it improves horse power and miles per gallon?
I am thinking about getting this for a -75 AMC Pacer with a 258. Apart from my intake being a single barrel, is there anything else I should worry about?
Instead of using the BBd Sniper try the Sniper 2GC www.holley.com/brands/sniper/products/fuel_systems/fuel_injection/sniper_efi/sniper_efi_2gc/ unit. The throttle linkage is a universal design instead of a specific set-up fo the jeeps. Everything else is pretty straight forward. You will need to upgrade your fuel system to provide EFi pressures (60psi). Thx J
Will this work on 4.0 h.o jeep xj 1994 model
Slant six🙏🏻
Will this setup work on a slant six? Ignition module and all? Not sure what a 4.0 firing order is
This would work on the slant six, but our Sniper 2GC would work better since the bell crank is universal and works with a variety of throttle and transmission set-ups. You can use the stock electronic or points distributor with Sniper and our Hyperspark ignition box and coil also. Sorry, we don't offer a Hyperspark distributor for them yet. Thx J
Will it work for non Emission 4.2L
Me interesa el kit que vendes donde lo puedo comprar o conseguir soy de la Ciudad de México
My Jeep came with 1 barrel, and 2 bolts, do i need to change my manifold intake?
That is a possibility, but check to see if anyone makes an adapter plate for your application first! Thx J
This is cool, but retains all the exhaust pulse tubing and vacuum lines. I am very happy to get rid of all that rusted out junk....but now comes the smog test.....
I have a 68 c10 with 250 inline 6. Would this kit work for my setup or do you have a kit for the Chevy 250
Our small bore 2GC Sniper would be a better fit.
www.holley.com/brands/sniper/products/fuel_systems/fuel_injection/sniper_efi/sniper_efi_2gc_small_bore/ Thx, J
Will this work on 87-90 yj's with the 4.2?
Si
Yes
I have a 91 YJ someone put a 258 in from a 4.0. Can it also be fitted easily? P.s. this was very straightforward.
So what if I didnt want to change the fuel tank that has no internal fuel pump? Would I use an inline?
I see now that this kit PART# 550-858K comes with a pump and inline filters
@@pkturpin You got it!
@@HolleyPerformance Where do you recommend mounting the inline pump?
Hi, Iwant to ride the Holly bbd EFI SNIPER in myJeep,Iask youhave to buy a atank and ignition. My Jeep has a HEI ignition and it has a aHolly gas pump. What it has is carburation problems with the BBDCarter.
Hello, my E--mail is calvoalegre@gmail.com. Iam from Puerto Rico.Iam about to buy the Holly Sniper BBDfor my jeep CJ7.Iwant to know,do I have to buy the ignition,and the Tank obliged? My CJ7 has an HEI ignitionand electric pump on the Holly brand line. My investment depends on that information.I understand that the product is very good but i have no experience in the field. I need the your valuable experience. Thank you.
I have a 1971 CJ-5 with the Dauntless 225 ci v-6 and wonder if it’s worth it for me living in NYS and driving it 6 months a year.
Cost?
I saw they had a return line hooked to the throttle body when they used the holley returnless fuel pump. Was that just for show or am I missing something
I was wondering the exact same thing.
Will it work on suzuki samurai?
Ha ha, here for the same thing. I think it will. Currently running a 38 Weber.
i have a 1980 cj7 original its has a dodge 318 carburador and im going mad cuz i spend 2.5 litres of gasoline in 5 milles
I have a 1983 that may need the stock MCU replaced, I'm in California will this kit pass california emission inspections
This system has not been verified to be emissions legal. -Keith
why wont this work for 87-89 258 yj's?
Different fuel tank. It will work in theory, you just have to have an external fuel pump
By the way my 1984 CJ 7 I live in New York
What does BBD mean
Doing a great job I need to do my jeep also can I get your phone number and what state you live in Appreciate it
Um sure lol wanna come do that to my jeep ? 🤣
I find it kind of funny so many are giving Holley their hard earned money for what amounts to an electronic carburetor. EFI? No. It is not.
Needless overcomplication and expense for those sold on 'new and electronic vs mechanical is always better' ? . Yes.
Agree. Added a Weber 32/36 on my 232 and it ran lock clockwork. On and off road. About the only time I know electronic is better is when constantly changing elevations. Otherwise, there's nothing wrong with a good running carb. I get 16-17mpg regularly.
I'm confused. It uses a high pressure regulated fuel pump with two 100 pound per hour fuel injectors and an adapting learn computer.
All I am seeing is 💰, and lots of it..
$1000 for that ??? Shit , idk about that
over 2000 bucks for a fuel system and distributor? no thanks. Not enough gains for the money and time.
Installed the Sniper EFI but my smog tubing is blocking the fuel inlet, which 90 degree fitting should i use in place of the one that came with the kit? Is it part number #98220berl?
