The best thing about the video is seeing your parents help you, especially your mom.. I would be so hyped..
@@marceltristan8632 what is instagram ?
Awesome video and project. Can't wait to see this progress.
Keep them coming sir , I really enjoy watching your build! Thank you for sharing!
Excellent work 👏 👍 👌 you've done your homework brilliant
Just subscribed. Great video. I luv that your parents are helping you with the build. 👍👍
G'day love the colour green you painted it
Man I want to get that same swap going !! Awesome video!
love your project. Hope to do one myself one day and these vids will surely help.
Awesome! Keep them coming 🇺🇸👍
There's a lot of "black magic" needed during these swaps. Just be keenly aware of geometry with the driveline after the install.
Great video!
Great job congratulations
The original radiators in the Humvees were leaned back at quite an angle to match the hood line compared to a civilian truck with a Duramax. The electric fan seems the smartest choice.
The mechanical engine fan on the duramax with the original shroud has worked great so far with the new aluminum radiator. My temps have never reached 200 degrees. I'll be adding electric fans to the front for the AC when I tackle that project.
Your parents helping with the build? Tear to my eye.
They help with things I need an extra hand for or an extra set of eyes.
Thank you for posting your duramax project it inspired me to go ahead and do my own swap. Did you keep the duramax fan or did you need to replace it.
Thanks for making these videos man, please keep up the good work. very enlightening as i'm seriously considering the same swap on mine... 6.5 just blew up. I my just find a GEP 6.5 but if the body has to come off why not go big right? Anyways keep on rocking with it, i'm subscribed !
Thanks man. Yeah, my 6.5 just didn't have the power I wanted so I went this route. Trying to keep it up to be able to post something each week. Hopefully it helps some people or at the very least is semi-entertaining. Thanks for watching! And let us know if you start your swap too!
U need Sand blast machine, and then epoxy paint and it would be perfect, not enamel, enamel craks, no resistance at all.
Where did you get the parts and everything? How’s the truck working !?
Hey man, what fan did you replace the stock duramax fan with to fit in the shroud? I also rebuild Humvees @splitbuilds.
There is a couple companies that will sell one but they are basically just cut down factory fans. I cut mine down as precise as I could, taking my time with it, and tested the balance a little with some old equipement thats in my shop. The duramax engine fan won't be spinning at as high of rpm's as a gas engine usually. There are some forums of car builders that get into the discussion more.
It both hurts and motivates you when you see someone building your dream truck. This is exactly what I want to do with a humvee when I'm able to buy one. Any tips for someone looking to do this? And how have you/will you get it titled assuming you are going to?
I understand that. I always saw builds I would love to do so I finally decided to just hop into one. I watched the auction for about 9 months before I found a really good deal that I couldn't pass up on this one. It is titled already. In some states it's not as big of a deal. I would just research your state's laws on it or ask the people at the registration office. Some states won't title it for on-road use if the sf97 form is stamped with "off road use only". Luckily on the auction there are certain humvees that come with a clear transfer form. I believe it has something to do with which military branch they came from. Just watch for that on the auctions if you do go that route. The swap portion just takes a lot of time. You could cut down the amount of time if you go with a company that sells a kit, but part of this for me was to learn more fabrication and custom vehicle building. It really is just about how much your time and cost of parts are worth compared to the cost of the kits. Appreciate you watching!
Yup, buy from Govplanet.com, and get one from Georgia. As far as I could see, that's the only location giving you the SF97 without the dreaded "Off-Road Use Only" stamp.
I got mine in May, prices seem lowest then
Did you wind up buying a kit for the brackets to adapt the Duramax, or build your own? Great project!
I bought mounts from Tin Man Fabrication. This wasn't the build I wanted to try to teach myself how to build motor mounts for a swap. That's a heavy drivetrain. Thanks for watching!
You are building my dream truck. I am curious about the year on the Duramax. I have a 2013 Chev with the Duramax, and it has some shortcomings, including a known fuel pump weakness. While there is such easy access to the engine, and since you're changing the turbo anyway, it's a PERFECT time to update the exhaust up pipe, intake manifold, remove stupid stuff, and change the fuel pump to the CP3. Of COURSE that means more money, but you'll get some power and longevity in return with almost no additional effort. Liked and subscribed! Can't wait to see more.
It's an earlier model duramax. Ive already had the engine down to the block. Studded it. New y bridge, new fuel supply to cp3 pump. Checked injector balance rates. And a bunch of other stuff. That was all before I had thought about creating the channel or I definitely would have recorded some videos on that too.
Can't wait to get started on mine, doin a Cummins in mine, still up in the air about trans and 2wd/4wd t-case. Don't want any electronics. Question for you, did you make any body templates to see where or how far you might have to modify/lift the body for clearance, or are you just goin for it(deal with that later)?
I knew I needed at least a 2-3in body lift from reading forums on the swap. I went with a 3in to give myself a little more room. I did cut a piece of cardboard that fit the trans tunnel to be able to see how much clearance I had but with the 3in lift there is a lot of clearance around the trans. Seems more for the engine clearance.
@@tossthewrench I keep hearing that it needs a body lift for clearance. I need to see one in person to see if maybe it can be done without it(maybe modified oil pan). I was thinking about pulling the body, then pulling out the stock drivetrain, then putting the body back on to make a wire-form tunnel or templates all the way front to back to help with mock-up.....also, I noticed your engine is pushed a bit to the right. What made that necessary? My exhaust and turbo are on the right....so that may present a problem for me..
Thanx for responding to the questions, the input is very much appreciated!!
That sounds like a good way to set up a mock tunnel that you could work around to help with fitment.
The original engine is angled to the right also mostly to make room for the front driveshaft that runs along the drivers side of the engine.
Nice build, what T case are you using?
It's an mp1226 manual shift t-case.
Hey man , Any chance you could explain what you did for the front drive shaft carrier bearing modification ? That would be greatly appreciated , Thanks in advance !
I havent done the mod yet for that. I explain my plan a little in the stainless radiator tubing episode a little. Once I get it running in 2wd I'll do the mod for it. I'll create a custom bracket that will move it down a little and maybe back some too. Hope this helps if you're going through the same build.
@@tossthewrench yes that helps , just got the engine dropped and body on , gonna run all my wires and get everything mounted to where i can drive it , then pulling the body and drivetrain back off and doing full resto ! Thanks for the reply bud !
Where did you find the donor engine and trans? I assume a Duramax is a lot more diffcult that dealing with a cummins motor right?
I haven't ever messed with a cummins motor so I can't really compare personally. I just looked different places for a donor engine and tans and came across one that was pulled from a wrecked truck.
Hi do you recommend any conversion services around LA
I'm not very informed on the different companies doing the swaps. I just knew I couldn't afford to have someone do it for me. I have communicated with Xtreme Hummer Performace and Dmax Swap before and they seem very informative and helpful. I'm not sponsored by any of them tho.
What type of cooling fan did you use to replace the factory on that comes with the Duramax which hits the HUmvee radiator shroud, Thanks
There is a couple places online that sell one that will fit. Modmafia is one place if I remember correctly. They are basically a chopped and balanced duramax fan.
@@tossthewrench What driveshaft did you use? Thanks
what motor mounts did you use? did you get a swap kit or are you doing this all custom?
Motor mounts are from Tin Man Fab. Doing it all custom pretty much. Thanks for watching!
What's an estimated cost , both the engine itself , and labor ? I'm contemplating the switch.
I'm not sure about labor since I did all the labor myself. If there is no body work and paint to do, it would take a lot less time than it did for me. I've estimated my cost for everything so far including the humvee as just over 20k, less than 25k.
Hi buddy I have a question can you do swap on my 2002 H1?
At this time I'm not doing swaps for any customers, but if you have questions or anything on the swap let me know and I'll try to help answer them!
Hey. Bud…. I know these are old videos, but I keep watching them. I have a 1165 …. What size Axle gear did u use or stay with stock? Thanks
They are the stock axle gears. The ratio works just fine with the powertrain swap and larger tires.
Thanks for the information!! so only thing different is the Duramax and transmission, right??
I did use the new transfer case from the duramax and allison as well. I'm not sure if the humvee transfercase would have worked or not. It might have a different spline count on the output shaft of the transmission.
Ok cool!! I need to know what you had so I can pretty much put the same thing back into mine…. did you get all that stuff from a wrecked Chevrolet truck? Or did you buy all that separate?
Hey, it’s still running pretty good? If you get time, make it update video.
If any engineer redesign humvee with small but powerful engine, flat floor for luxury seats ,with luxury interior then it would be revolutionary suv. Now it is not good for drivers and passengers.
What is absolutely necessary for a dmax swap?
Engine, transmission, transfer case, wire harness and ecm/tcm, engine mounts, transmission cross member mount, drive shafts, body lift, fuel tank mounting modifications (or your driveshaft will hit), fueling upgrades (duramax requires more than the 6.2 or 6.5), shifters, throttle pedal, modified engine fan, intercooler, intercooler tubing, exhaust, steering modification, a way to read engine and transmission info (gauges), 12 volt system. I'm sure I'm forgetting some stuff tho
@@tossthewrench you’re the goat man
What year is your duramax
The engine was out of a 2008 truck.
