12 Valve Cummins + Allison 6 SPD in a Humvee!

[@spartin86]

You made a Cummer.... Love it. .

[@redhotchilipapa5388]

The best of both. This is awesome. I’d daily tf outta this beast.

[@killakidz360]

Same

[@davidcraft4462]

Outstanding! Need more from you all!!

[@quintenhegstad2026]

God that setup is literally my dream

[@hugomadrigal4171]

I love your videos and they inspire me to want to create my own humvee, greetings from Mexico

[@boxwoodgreen]

The Cummins is the one you'd choose if you wanted a better chance of a ride after an EMP event ?

[@dante04srt]

You'd need a non-computer controlled trans for that... hehe

[@boxwoodgreen]

@@dante04srt Those do exist, but I don't know, and doubt if any are currently being manufactured new. Perhaps the Plan B guys know ? American auto suppliers can build anything if there's a market for a product. The people who are buying custom vehicles and want EMP hardening built in, have the $$$ to invest. We know that because those vehicles are already "Expensive" with a capital "E". There's a HMMWV / Hummer rebuilder an hour from me who's end products are circle around the $250K mark. Granted that's the mega-luxury end.

[@dimmacommunication]

@@boxwoodgreen The huge problem is that as the guy in the upper comment said the engine isn't computer controlled but the trans is :( At this point a more modern engine would be better.

[@boxwoodgreen]

@@dimmacommunication Then you're "cool vehicle" that's fun, and capable. As long as there isn't an upper class solar flare, or an EMP strike. The average new car has hundreds of computer chips that control most of its functions. The luxury cars 1000+. In the 2 scenarios above every one of those chips will be fried in seconds ... as will every one on parts shelves. It's dead forever where it sits, or crashes.

[@VeRSINGOnTheGo]

Agree with you 100%, there has been the Rezvani Tank that has this and is certified, why not an option with Plan B. Do know there is a device that can been wired in between the battery and computer (Where ever is located) that will protect. Would love to have the many luxuries in one of these that is totally rad. Anyone know the towing specs off the cuff? Am trying to decide to run with a Plan B, Rezvani or....the fact that the later is built on a Jeep frame, 4k in amour is a deal breaker!

Plot twist, Mexico is asking for your Extradition for speeding

[@Soldierboy1986]

That’s the way it should’ve been built in the first place!

Love the build

[@cotynietling2567]

Awesome build ome day i want one built like this but with slant back

[@octavioortiz923]

Can you guys do a video on the Riot model armored hummvee in the background during the day so we could really see how awesome it is? Maybe drive it around or something

[@planbsupply9318]

We will do a video on the next group that are coming up. That particular model was going out for a Duramax swap so we did what we could even though it was 11:30pm and raining outside. Thanks for the feedback - Happy Holidays

[@TacticalNacho]

Nicely done!

[@mcwendel8066]

If it was your personal truck which do you prefer Duramax or Cummins? And would the cummins take a long time to warm up in New England winters?

[@JimmyTheProstitute]

I would prefer a cummins for reliability, easy maintenance, cheaper parts. Both would take a while to warm up. Duramax might start faster because it has glow plugs.

[@tvwg4927]

What about using the 4bt engine

[@patriotkieler9750]

Curious on the MPG on that now. it's such a light body.

[@planbsupply9318]

If I told you the truth, you’d think I was lying… it’s THAT drastic. Let’s just say it’s over 20mpg in all of our testing.

[@abc-ed1nr]

Just tell us!!! What kinda power is it tuned to? What mpg do your Duramax conversions get?

[@nolanwillis9812]

I am assuming that none of the conversions have all the emissions controls that modern diesels have, right?

[@davidlamberson5435]

This is the 5.9 -12 valve that dodge used in the mid to late 90's?

[@bryanford1139]

yup

[@ironmarshmello2982]

What size and offset are those wheels? I like how they are pretty much flush with the body.

[@op665]

I’ve been thinking of buying a beat up old humvee and ripping out the stock engine and jamming in a Cummins turbo diesel in with a new power train but i don’t know the specs on it.

[@garyallen8680]

What cab be done to thr Cummins opposed to the Dmax. Heard about 1000hp Duramax. Cummins possible equivalent? 1000hp? Extra cost Right hand drive.

[@pyeitme508]

Rad 😎🇺🇲

[@abc-ed1nr]

Do you need that hood scoop to make it fit? Or could you leave it stock

[@ReneBautista50]

I have a 1995 HumV it’s the civilian model 12volts, I’m highly interested in dropping in a 6 cylinder Cummins engine in it any advice will be welcome, thanks

[@planbsupply9318]

The 12 Valve is a long engine and using the Allison helps to complicate things even more. You’ll need to lift the body 3” or so (we have a kit) and then depending on your dash/doghouse area you’ll need to make some clearance adjustments. It’s a learning process for sure. Lots of little things need to be addressed to make it work properly.

[@DecusTex]

What do y’all use for the transfer case?

[@hourshofficial1979]

Wow! My Lovely Car

[@arrongonzalez215]

I noticed in the cab, the center console that normally separates driver and passenger is really low to the ground compared a normal h1, did you modify the cab after installing the new engine? Can this be done to any h1 after replacing the engine to a v12?

[@jake66]

This is a military HMMWV. If you strip down your H1, it will be the same

[@chadperez9170]

Cost?

[@311mdub]

Love the truck! You guys located in northern Utah? Do you have a show room one can walk thru?

[@planbsupply9318]

We’ve got a production facility in Willard. If you’d like to swing by - give us a call. We don’t have a showroom as 99% of our customers order remotely from places like California, Texas and Florida. We’d be happy to tour your around though. Please make arrangements as it is an active production environment.

[@AYAN-bu4kr]

Are you guys keeping the stock NP242 or what TC are you running?

[@SteedDolan]

what Allison kit did you guys use?

[@alexmiller5302]

BETTER THAN PREDATOR INC 😎👍🇺🇸

[@we-zk7xp]

Wait... you had to fab a new fuel tank? Any loss or gain in capacity?

[@planbsupply9318]

Its roughly 28 Gallons - Slight gain

[@we-zk7xp]

@@planbsupply9318 that's awesome. Also... does the 12v swap leave room to center the front differential? (I love the idea of a single half-shaft replacement part for all 4 corners and less shaft angle on the front left too.)

[@jenslieber5883]

Great idea best Greatings from Germany Jens 988 my typ orginal I like 6bt cummins engine 👍

[@quintenhegstad2026]

Did u need an adapter for that transmission?

[@bryanford1139]

Yes you do, they were never mated together in anything. Couple different companies make them...bit on the pricey side tho....

[@bryanford1139]

....and flexplate...and usually starter too

Yall can use my humvee as a project humvee as long as i get it back in the end..ill just owe yall for the rest of forever

[@florincioara9547]

Which Allison transmission is it..?

[@Subgunman]

Bottom line, what does this engine-trans conversion cost with the necessary mods for clearance???

[@planbsupply9318]

We currently have the whole conversion priced on our website www.planbtrucks.com/cummins-humvee

[@jamesbroughton9900]

This is legit what I was thinking of doing this morning, that’s my dream build, any chance of a price point on a build like this? For future reference?

[@abc-ed1nr]

It’s on their website it’s nearly 50 grand. I’ve been looking at doing it myself, predator sells motors mounts and trans mounts, CA Conversions can do the Allison but you’d 10-16k depending on if you have a trans already or get one from them. You could reuse the 4l80 too. Reman Cummins ain’t cheap anymore and low mileage donors hard to find.

[@SHARPPITT]

That’s awesome guys , that’s what I need in my hummer , what is the price of that combo ? great work , God bless

[@ttss5726]

They have a website for that info..... as they say if you have to ask price you can’t afford it

[@SHARPPITT]

If I can afford how much I’ve spent on my humvee I can afford this combo , I always like to ask , that’s how I like to educate my self , thank you

[@jake66]

@@SHARPPITT I believe it says $43000 in the description

[@bryanford1139]

How did you make the Allison work? Stand alone shift controller?

[@bryanford1139]

....I used a stock GM computer with EFI live Autocal and custom fabricated wiring harness (EMP resistant--in theory(not tested 😁))

[@rand0mGT]

How much is this?

[@bryanford1139]

Instead of the body lift...couldn't you drop the drive-train 3 inches? I always thought trucks with body lifts look terrible...

[@bryanford1139]

thanx for the reply..... in case anyone's interested....1995 6BT 5.9/2006 Allison 1000 6-speed/1975 Ford NP205 setup w/adapters is only about 2 inches longer than the stock drivetrain. So, custom engine and trans mounts needed, only a 1 in body lift needed, stock front driveshaft length and shortened rear. Customized oil pan if you want to retain ground clearance (who wouldn't?).

[@papsikheltv]

good truck this kind of transmission 1000 2000 series

[@cch201992]

mpg?

[@planbsupply9318]

Not sure quite yet. It's probably 14mpg.

[@planbsupply9318]

Casey - After roughly 500 miles of initial testing, we determined ~19mpg average

[@cch201992]

@@planbsupply9318 hell yeah that's what I'm talking about. Need that range for long travels especially remotely. I thought your initial estimate was super low because my ram 2500 gets 19mpg hand calculated mixed driving. Definitely want the cummins over the duramax for alot of reasons.

[@jake66]

[@jaysoncarte9]

I wouldn't trust the work of this company. We bought one of their hmmwv's a couple years ago from the guy who bought it from them and it was very shoddy work. They bed-lined over everything inside and in the engine bay - even things that shouldn't be painted. The roof rack is extremely poorly designed. The custom aluminum hard top leaks at the seam between the front cab piece and the rear. Very half-assed work.

[@subcomandante77]

Damn

[@Sickoloko24]

Good to know I’m steer clear of them.

[@maneateroftsavo]

So you didn't buy it directly from them?

[@jaysoncarte9]

@@maneateroftsavo we did not buy it directly from them; we were the second people in line. I did, however, contact the company about the things that I mentioned and they doubled down protecting themselves, whereas they could have put the blame upon the original owner, they just said that everything they did was good to go. I had the sales slip for the rig, so I know what they charged for, and that it was crap work.

[@abc-ed1nr]

Damn thing must be so loud to drive

[@williamgrissom1995]

Ok the Cummings is the choice vs emp attack. But why a 6 cilinder instead of a V8? The six is longer as they said. But I think a V8 Cummins diesel would be shorter and might fit even better. I would be very interested in seeing if the Cummins V8 would be better fit and work better in a hummer. But I would never choose a gas engine for a military hummer for civilian a daily driver choice. A diesel powered hummer is my personal choice, if a miracle happened to grant me my dream 4x4 choice. I'm disabled, so the cost of a hummer is going to be out of my grasp period anyways. But I can dream of my perfect setup, even knowing it will always be just a dream. I dream of having an underground bunker to live in and a fixed up hummer as my daily driver. Sure I have specific preferences I would prefer of both things. But since there is zero possibility of my ever getting my dreams full filled, I don't see the point in being specific. My dreams are just that, dreams. Nobody really makes dreams come true. There is nothing I can do to make my dreams come true on my disability. But I sure hope and pray, that someone's dreams does come true. 😌🙏
