BIG V8 Power for a Jeep Wrangler JL or JT Gladiator and NOT from a HEMI
Vložit
- čas přidán 3. 12. 2022
- When it comes to big horse power and torque, the kind that you really want when driving something like a Jeep JT Gladiator outfitted with EVO trailing arms and double throw down system over big whoops, nothing short of a V8 will give it to you. And, while a HEMI swap is the first thing that comes to most peoples minds, there is another option coming soon for the Wrangler JL and JT Gladiator and that is, a Motech Gen V LT V8! In this video, you'll get to see and learn more about what Cindy and I hope to have under the hood of our Gladiator and soon.

What differentiates the LT from everything else? First let's be honest everything we see here is old technology, very old technology. By the end of World War II the internal combustion engine had pretty much reached its pinnacle. Overhead cams, multi valves, direct injection.... its s all been done, probably before most of us were born. Google the Rolls-Royce Cressy engine or even the good old Allison V12 you will be amazed at the technology in those engines, they make our engines look like toys.
The roots of the modern Hemi engine really lie in Chrysler's attempt at an aircraft engine that was fitted to the later iterations of the P-47 Thunderbolt. The engine proved powerful and could push the Thunderbolt over 500 miles an hour, but once the jet engine came onto the scene the internal combustion engines were old news. I always thought Thunderbolt would make a better name for a Challenger or Charger than Hellcat or Demon.
The LT engine runs a structural oil pan which supports a 6 bolt cross bolted main cap. Aluminum heads and block mean lighter weight and better cooling, although this has been true since the early LS from the late 90s.
Potential energy, that's where it's at. An LT1 runs 11.5 to 1 compression in a 6.2 l engine. The modern Hemi, which really isn't a true Hemi any longer due to production costs and other factors has 10.9 to 1 compression.
GM has applied the technology required to allow an 11.5:1 engine to run on pump gas. The combination of direct injection and continuous variable valve timing allows GM to do this; neither the LS or Hemi has CVVT.
What you end up with is an engine that has tremendous power, especially torque at lower RPM; this is the reason the LT 5.3 can run with the larger engines, especially when equipped with the 10-speed transmission. BTW the 10-speed transmission was developed in conjunction with other manufacturers like Ford, Honda and Toyota.
Unlike an LS3 or Hemi the LT idles at very low RPM and has tremendous torque off idle, I like to say it's halfway to a diesel with its higher compression and maximized cylinder pressure. We have run the 6.2 LT's against Hemi's and LS3's with higher horsepower ratings but more often than not the LT wins.
The new inline 6 twin turbo looks very promising but it is really nothing new. I'm a big fan of the inline 6 and it appears Chrysler has taken a look at the BMW 3 l M series engine. That's not a bad thing they tout V8 performance with better economy and emissions. Smaller displacement engines with forced induction have often attempted to replace the good old V8, like the Ford Ecoboost engine.
I drive about a thousand miles a week in Wranglers with engines from the anemic 3.8 all the way up to LT'4's and various Hemi's. Without question the LT's have the best drivability, fuel efficiency and transmissions IMO.
The day will come when the large displacement V8s will be outclassed by the smaller displacement supercharged engines and electric motors. But for now if you have a large heavy vehicle with a lot of drag it's hard to beat the overhead valve American V8 regardless of manufacturer.
@WranglerJKLS Thanks for chiming in with all that great info, Robbie! Always learn a ton from you 👍
@@frank39490 I love my 8.1ltr engine drivetrain in my 2004 3/4ton, Yukon XL. I might do something crazy one day. I saw on Autotrader once someone selling a rust bucket early 2000's, Yukon XL 2500 from the salty road states with this drivetrain for $3000. That drivetrain would work great swapped into my 1989 Dodge 4x4 project.
Motech is an unbelievable shop. Watch one of Robbie’s videos and you know these guys really know what they’re doing .
Once you here that sound of that engine, it's too late. They got you! Watch out, Eddie's got the fever.
LOL - Oh yeah. Between the LT we have in Moby and our 392, I've had it for a while now :)
@@wayalife That's right. I forgot about the 392. So you've had the fever and it's getting worse and now you're trying to spread it.
At 3:22 in the video you can see the front tire and fender of my Jeep. Should be done any day now. Getting an L86 and I cannot wait.
LOL - that is awesome 👍
I live 15 mins away and had no idea they were here in Vegas. Definitely going to do this.
I love it, and it gets better mileage than the original V6 they come with. That is amazing that you get all that extra power and torque aaaaaaand extra mileage, incredible 😮
Yup, it's amazing!
I’m so excited for the LT4! Thank you for doing this. Big fan of Motech.
Awesome!
Great video! You always have great content that keeps me interested. 22 years ago when I was 19 years old I did a GM fuel injected motor swap in my 84 CJ7. This was before LS swap became a cliche. just recently we bought that same Jeep back and my son and I are fixing it up for his first vehicle. We bought a 2022 JLU for my wife this past summer. After owning a Yukon Denali with the 6.2, I thought it would be amazing to have the 6.2 in the JL. I can not wait to follow your build. Thumbs up Eddie!!
Thumbs up to Cindy too!! 😊
Awesome and congratulations to you.
Super exciting!! Can’t wait to see it come together!
Thanks Rachel! It'll be a while until it actually happens but we are excited about it.
I love when things are done well and complete. Keeping as much of the OEM assembly is key to good reliability, so this is probably is a great option for those who cant find a 392.
Being that the 392 is being discontinued, I think there will be a lot of guys who will find this to be an attractive option.
@@Oilngld Umm, not just the 392 but HEMI as a whole for Dodge and RAM. A lot of it has to do with new EPA standards coming in 2024 but most of it is from Jeep trying to stay ahead of it and make 70% of their line up electrified by then. This is all directly from Stellantis.
@@wayalife they are going to kill Jeep. Maybe the new Jeeps will have a V8 speaker for nostalgia like the electric Charger ;-)
@@wayalife I truly am not a fan of EV's. If the time comes, and it looks like it is, I will buy used before new.
@@Oilngld there's a difference between infringing on a constitutional right and "luxury". The ATF is getting spanked because they are (and have been) infringing on constitutional rights. The EPA however can do whatever they want, because owning a vehicle is a luxury, not a right unfortunately.
As always a great video . Thank you Eddie and Cindy…
Glad you enjoyed it :)
So love these vids. Now we get to what this build on the JT and then the ensuring off-road vids, yeh!😊❤😊
Glad to hear you're liking it :)
Nice to see some alternatives to the hemi swaps!
Happy to hear you like seeing alternatives! 👍
Much respect for going a different route and being unique. Looking forward to seeing this play out and some vids. Would love to check the build out in person one day if we ever cross paths. 👍👍
I hope we do get a chance to meet someday 👍🏻
Great video! Can’t wait to see the LT4. It was pretty cool getting to see my LT1 10 speed and atlas swapped big green jku in the background of the whole video!
LOL - awesome! Glad that we got your Jeep in the video.
Very nice. Thanks for sharing.
I've always preferred the LS, LT over the Hemi. I can't wait to see one in your JT.
Awesome! HEMI's are nice but I agree, the LS/LT's have a lot more going for them when it comes to swaps.
@@wayalifehow dependable and reliable has your jeep been with the Chevy engine swap? Any electronics issues, codes popping up? And can you have a manual transmission with the Chevy engine swap?
Not gonna lie, soon after we got this engine installed, we did have problems and we documented it in one of our videos. However, we later found that it was just a chaffed wire causing the problems and once that got fixed, we haven't had any more issues. Been really happy with it since.@@user-fk2dm5oy9f
Awesome! Kalan and Motech are the best!
Yes they are 👍🏻
I 100% LOVE mine! Im glad to see @wranglerJKLS is starting to work on the JLs!
Very cool :)
AWESOME 😎😎! Greetings from Greece!!
Glad to hear you liked it and nice to know we have fans in Greece 👍🏻
Great video guys!
Thank you my friend. Always happy to share a little V8 fun 😎
Whow, what an engine, love it, together with the suspension it would be the most sick gladiator in the world 💪✌️👌🥇greetings from the Netherlands 🇳🇱❤️🇺🇸😉
LOL - thank you :)
This is going to be sooooo good. Looking forward to this Eddie!
Awesome, glad you enjoyed it
❤ You are great! Love your vlogs.
Humbled that you would say as much, thank you
I've never been to Vegas. This is a good reason to travel out there! Not sure about that drive to Florida though.
I knew motech would start on Jl and Jt Eddie your videos are awesome
Thank you. Truly humbled that you would say as much.
Absolutely badass!!
Glad you like what you see :)
Lol That’s awesome! Can’t wait for that series of vids!
Glad to hear you're looking forward to this 👍
The Gladiator is going to be insane!!! I can’t wait to see it, and hear it.
Glad to hear you're liking what we'll be doing 👍
Can’t wait to see your JT, I see that in the future for my JT as well. 👍
Awesome :)
RattleTrap used to be my favorite Jeep build but after this swap I can safely say that Moby will become my new fave. It's already a dream Jeep and I have a great one but it's just on another level that many of us will never get to. Kudos my friend.
LOL - awesome and thank you. And, to be clear, Moby is our JK and it already has an LT under the hood. This new one that we're wanting is for our Gladiator :)
@@wayalife Ahh of course. I was confused. I meant the Gladiator. My favorite rig (aside from my own) that I've ever seen.
Yes, Moby is a total badass. I remember the video is where I learned about the LT/L86 engine. (before that, I thought they were only LS engines!!!)🤙
I hope you will do a full Video on the engine install.
We’ll see what we can do
Motech swap was the best money I’ve ever spent 👍
We’ve been real happy with our too 👍🏻
How much?
@@sithinstructor Depends on what you decide to go with, transmission, things like that. But, you're looking at about $25-$30k
@Wayalife wow. That's actually on yhe more affordable side in comparison to the hemi swaps
Man, you look like a kid in a candy store with a hundred bucks in your pocket! The LT4 has a sick amount of power, I'm sure you'll find a way to enjoy it! Look forward to the build. Cheers.
LOL - you know it!! 🤪
Take your 392 back and do a side by side with the 5.3 shop Jeep for the ultimate Motech commercial. That would be spectacular to watch.
LOL - like I said in the video, the Motech JL would give our 392 a run for its money. Never said it would beat it. But... a 6.2L LT4 would spank it.
Drive it like you stoled it, Eddie!
Now that is cool!
Glad you liked what you saw 👍🏻
I am dreaming of a Motech upgrade in my 2020 JLU. It sounds like by the time I am ready, Motech will be in full swing with these things. I am really looking forward to hearing how you like it and comparing it to the 392.
Well, so far, we've been loving the Motech LT that we have in Moby, our JK wrangler and really looking forward to getting one in our JT because of it :)
I look forward to the V-8 in you Jeep Pick-up thanks
Awesome :)
Thanks for sharing yet another informative video and for giving me an opportunity to see the progress of my LT1/10L90 swap (1:03) on my Moby inspired Black JKU build (Fir-Na-Tine on Wayalife) 👍🏽
LOL - no way, that is too cool! Glad we could show off your Jeep in this video 👍
I had a fully loaded Jeep Gladiator Mojave with a 6-speed manual transmission. Thinking about going that route again. Seeing your video got me thinking about another Jeep Gladiator Mojave with a manual transmission...LT4, Atlas transfer case and a G56 manual transmission. Tremec 6-speed will hold up to the hp/tq. Would be one sweet setup if its doable.
ya get rid of that 3.6 Manual . they are useless in a off road truck .
Awesome option 🥳
Thank you, glad you like what you see.
Amazing brother ⭐⭐⭐⭐⭐⭐⭐
nice and great video
🙏🏻👍👍👍
Glad you enjoyed it :)
I live down the street from ther . I pass it everyday. I just hope one day I'll be ready for my swap one day 🔥
Awesome :)
Wow! You squealed the tires. Big whoop
Wow! You made a post on CZcams. Big whoop 🤪
Hey that’s pretty neat!
Glad you like it 😎
Cant wait to see it, and hear it :)
It may be a bit but glad to hear you're looking forward to it.
Awesome videos 👍👍👍
Glad you like them!
@@wayalife But how could we contact with you?
That LT4 should definitely wake up your Gladiator! I've got my heart set on the new GM 6.6L out of the 2500 trucks, with either an 8L90 or 10speed if possible, for my wife's JKUR.
Wow, now that would be awesome
Very nice 👌 👍
Glad you like it :)
So sweet it would be awesome to see a 7.3 Godzilla swap
Any MT options?
great engine! Does it fit in place of my Ecodiesel?😉💪🏁
Saludos desde chile amigo ...
Fantastic, informative video as always Eddie, but you need to have a couple minute Ripley outtake at the end of all your videos! Hope he is doing well!
Glad you enjoyed the video and yes, I guess it’s been a while since we featured Ripley 😊
I agree with Kalan, I definitely think an LT4 would be good for a big build like your JT. I’m going to be swapping in just a basic 6.0 LS for my XJ but it’s 4300lbs with me in it.
Oh yeah, on an XJ, 6.0 LS is all you really need. And yes, I think an LT4 is in the works for us :)
I would have just left your JT there for them to do, and walked home! Yea, that would be a long walk but think about it, they would probably be calling you to come get it by the time you get home! lol
Motech does amazing work!
LOL
Will they give a credit for the Pentastar engine?
I'd love to see a race between an AMW Hellcat swap and Motech LT4 swap!
That would be fun.
Great video as always !! I want to buy the radio bar do you have a website I can go to ?
Glad you enjoyed the video and you can buy one here wayalife.com/store/proddetail.php?prod=PARTS-CB-BAR
I drive past the shop daily
Very cool :)
Americas Most Wanted to doing the Hemi, Demon, Hellaphant conversions and they went through all the details to make a smooth swap.
Clearly, to each their own. Being that you're a fan of theirs, that's who you should have do your swap. 👍
WOW
Is there any update on the gladiator motor swap ??!? Really want to hear that supercharged V8
We're still working on making it happen but we've had to put it off for a bit due to other projects.
Have they done a LS on the 6 speed on rubicon JLUs? Would be a dream come true
LS/LT*
Not sure why a Rubicon 6-speed would be a dream come true. The new 8-speed would be better in my opinion but then, they've been doing 8 and 10 speeds for a while now.
Not just motech , but I see it with other LS swaps, they need to get ride of the corvette covers. Someone need to make some Jeep ones
The covers are used to help with clearance in a Wrangler. But, it would be nice to see different covers.
Good times for sure. I can only dream of such things, for now I still gotta find a way to even afford a jeep lol haha. Though I think for my my dream engine to get the torque/hp and gas mileage I would like, think I would like a 5.7 hemi But that is personal preference though. 1st step win lotto to afford everything lol.
LOL - we should all get what we think is best :)
Hell yea brother! She’s gonna rip!
That's what we're needing :)
LT4 💪🏼👌🏼😎. When I grow up, I want to be Eddie!!! And here I am waiting for my 392 with only 470 HP😢.
LOL - don't get me wrong, I LOVE my 392 and you will too! 👍
@@wayalife I like your style Eddie. Your motto should be “F it, let’s go for it!!!” You will for sure have The Ultimate JT when you do that badass swap! Congrats!
LOL - thank you.
Where is this shop, do they sell ready to go units or you have to take one to them?
They are in Las Vegas maps.app.goo.gl/SipDn1oSPVD9i42R7
What happened with this swap? Wasn't it supposed to be available for the summer?
👍👍 Wow!
Glad you like what you see :)
How about a 392 vs Motech LT JL drag race?
LOL - that would be fun but like I say in the video, this 5.3L would give our 392 a run for its money - not beat it.
Wondering if a cummins swaps are available? I have the ecodiesel, a cummins would be crazy!
I'm sure anything is possible.
Consider a 4BT 3.9L or 4.5L. It is a 4cyl version of the engine in the Ram 2500-5500's.
Is this going to be CA carb legal ? I heard him say Ca.
Thanks
Yes. Motech specializes in CA legal swaps.
Listening to the install and packaging work arounds with the shifter, the dual computer and using a JK tcase, I feel like you really have to prefer the Chevy motor to choose this over a hemi swap like AMW. I like the MPG call out but what else makes this route better? Or is it really just a matter of preference and trust in a shop you know?
HEMI's are great engines and I love the one in my 392. Unlike a swap where one is just shoehorned into the engine compartment, Jeep tailor fitted it and made custom improvements to ensure it would work great. Everyone I know with a swapped HEMI has overheating issues and other electrical issues as well. They are a lot bigger and a lot heavier and they require your firewall to be pounded in to fit. The LT is has direct injection, has higher compression because of it and CVVT (not just VVT) and that means you get BIG torque right from idle. Being that it's an all aluminum block, it runs cooler too. From experience, I can tell you that it works great on a JK and we have a single module. Getting the transmission to work on a JL/JT was an issue because of the lame drive by wire but to me, it's worth it for the 10 speed which is really nice. As far as transfer cases go, I would ONLY run an Atlas. Anything less, I would break and have broken. With all that said, this is just my reason for going this route - mainly, personal experience.
Check out Marvin at flex rocks and roll overs, he rolled his hemi and blew the engine because the intake held to much oil in it even though they waited and tried to clear out the cylinders. Even after weeks of being upright the intake manifold was still holding oil in it. This isn’t an issue with LS motors.
where is that swap?
My only question is do I build the suspension and axles swap first
In my opinion, there's no need to upgrade to a V8 until there's a need for it and so, yes, I would say suspension and axles first.
I don't suppose they can drop one of those motors in a manual JLUR?
JLUR is what it's now being designed for but you will need a new transmission.
Rad!
Glad you're liking what you see 😁
You know it's expensive when they don't even mention price. But so is a Rubicon 392.
I paid $28k for a 6.1 Hemi swap, with 545rfe in my LJ in 2006. N
However I found, no comparison to the performance of a factory designed 6.4. The 392 Rubicon has more of a performance sports car feel.
I don't doubt that a LS4 with super charger at 650 hp would be a fun way to go.
I always hoped that Jeep would release a Wrangler Rubicon with Hellcat engine. But when I realized that 2023 was most likely the last year for the 392, I bought one. No regrets, so much fun. Smiles per gallon.
Oh yeah, love our 392! As far as price goes, you're right in the ballpark.
Does that mean you're going to have to put a roll cage in that gladiator now because this can be a hard time for you to keep your foot out of the firewall
LOL - I really hate cages but Mel has been trying to talk us into one.
I want to see someone do a coyote swap
Great video. I have a 2021 jeep jlur with a 4 inch lift and 35s. Some ppl saying jumping to 37 I need ball joints axle shafts axel reinforcements ball joins… some say nothing… what are your thoughts!
I would never pretend to know more than what "some people" say or don't say but from my personal experience, I can tell you that I've had ZERO problems running 37's on factory Rubicon JL axles. Granted, I am just a mall crawler.
@@wayalife thank you!how many miles on the axels before you upgraded
It really depends on how hard you play. You may never need to upgrade your axles or at least, the housings. Ball joints wear out on any axle and you replace them as needed, just like a set of tires or brake pads. Rear shaft flanges can bend and front shafts can break and if they do, replacing them with chromoly ones is all you need to do. Just make sure that the front shafts come with full circle clips.
How would you pass emissions inspection?
Motech makes kits that are 50 state legal and will pass emissions.
My understanding is that the LS swaps aren't CA CARB compliant, unlike hemi swaps. Is that true? TIA
LOL - HEMI swaps aren't CARB compliant unless you get a kit that's got an EO. As Kalan made sure to point out, they DO on their kits.
Excited to see the results. A bit too much bashing of the HEMI for no good reason though. Got any beef with AMW? The HEMI is a relatively cheap and reliable option - mines been treading lightly for 2 years now in my JT. MPGs also correlate more with your weight and tire size as you will notice. So with your engine choice you going to add an AUX tank ? That would really interesting to see integrated with an engine swap. Good luck !!!
LOL - not sure who was bashing HEMIs or anyone who installs them. Certainly, I love them and my 392. They are old in design and Stellantis has cancelled them where as GM has been and is still developing new V8 and with modern technology. That's just a fact. HEMI's are also bigger and heavier and from personal experience, all the ones I've seen have all had overheating issues, especially out in the desert. That said, I'm glad to hear you've had good experiences with yours. Regarding auxiliary tanks, the first part of this video will show you what we did czcams.com/video/ae9GM6ykE_8/video.html
@@wayalife awesome !!! I will check it out. No desert here on the east coast !!! definitely enjoy your channel so keep the good stuff flowing. Curious on the exhaust system you are going to use in terms of mufflers and resonators and if there will be any drone. With your chop and the EVO setup (killer setup) there’s not much space :) also will remain street legal emissions wise ? HEMI defo old but gold ha ha
On our JK, we're running a Magaflow muffler and that's it. We love the sound it puts out but it might be on the loud side for some. As far as emissions go, we live in a part of Nevada that doesn't have smog laws so it's not an issue for us.
A Cummins swap would be even better. (EPA will get in the way though).
That would be cool too.
👌
Isn't the main reason people go with a Hemi because of emissions issues with LS swaps? My understanding was that you can't legally run an LS in a jeep that's later than a 2015 because after that year, GM has not produced a "passenger vehicle" with an LS. They put it in trucks, but that doesn't count as a "passenger vehicle." Emissions guidelines say the swapped engine has to be "like or the same" as the original, so you can't swap a non passenger vehicle engine into a passenger vehicle. Maybe I'm wrong and GM has started selling this engine in something that's a passenger vehicle, but if not I don't think it would ever pass emissions.
Actually, the main people go with a HEMI is because they're fanboys of Chrysler and think that you need to stay within family to be cool. Well, that and the idea that somehow, there will be less problems being that the motor and Jeep computer speak the same language. Trust me, you can still have emission issues even with a HEMI and have multiple personal friends who've had to deal with this. That said, Motech is the only shop that has California executive order swaps and theirs pass smog. You should contact them for more information.
@@wayalife that is good to know and great to have options. JSS has their EO for their HEMI swaps and I thought all LS/LT swaps needed to go to a smog ref... great that Motech is another option
when my 3.8 finally dies Motech will be on my short list becuase of their work to get SMOG/CARB issues taken care of
Do you install a manual transmission with your V8?
No, you would want to install a 8 or 10 speed automatic.
Next up a video on which 42’s do the best burn outs…
LOL
Noobie here, any recommended engine for a 6speed JL? and should a 2dr be a viable option?
As in, so that you can keep the 6-speed that comes on a JL? Also, Motech has done a number of swaps in 2-doors and they are badass!
@@wayalife Yes if it's possible to put a v8 and keep the 6spd or would I also have to get a new transmission
I think you guys need to get into an American most wanted JL or JT the work it mind blowing and the power it just stupid.
eh, I got an LT in my JK and love it. Seen an AMW in person and it had nothing but problems.
Any particular reason why you picked this over the AMW4x4? Oh, and the fact that cost was never mentioned means I can't afford it 😁
Actually, yeah. All the HEMI swaps that we've seen ALL have overheating issues as well as other problems. They're also bigger and heavier and their computers are locked. We've been running an LS in our JK for over 10 years and now run an LT and love it. We love that it's more affordable, is lighter, runs cool AND can be tuned with ease.
@@wayalife Awesome, thank you for the detailed reply! 🤘🏿😍🤘🏿
Take my JT
I'm not an engine conoissuer but if the LT4 is a stick motor, will you be having it converted to an automatic like you did Moby?
Most LT4s are 10L80s. We will have a 10L80 in his JT
@@MrKellyvevo Sounds exciting. Can't wait to hear that thing.
Can you do this and still be good on dana 44s?
Umm, I suppose if you ran stock tires and never pushed your Jeep hard off road.
@@wayalife dang. Already on 37s.
How much for a swap? Without looking, assuming $20k for the basic swap 5.2. Then up from there. If you have the money, hell yeah. These guys deserve a lot of credit to tinker tinker and tinker to make it run!
It really depends on if you're using a crate motor or one from a wrecking yard and what transmission you're wanting to use etc. But, in general, you're looking at about $25-30k to do this.
