Today on Swapology we put an LS7 intake and port injection setup on a Gen 5 L83 Engine. This video covers some of the differences between LT and LS engines (not all of them of course!) as well as the installation of some trick ICT Billet pieces to allow Gen 4 LS7 Intakes to be installed onto an LT engine!!

I was messing someone about a complete lower end. And I immediately thought it could be done and started to search glad I found your clip thanks for the info
Same and I still believe it can be done by any garage builder that can properly weld aluminum with a Tig ( a Tig is almost mandatory these days for any garage ) don't see why you couldn't cut the LT oil pan mounting flange off and a front sump LS mtr and weld them together and fill/ massage any clearance issues . To solve the pick up tube problem should be as simple as swapping to a LS oil pump on the LT mtr allowing you to runs a LS front sump pick up ? Or simply cutting the stock LT pick up point between pump and tube off and making your own front sump pick up by either melding the LS pick up to the LT pump flange or by sectioning the original LT pick up to go straight down into front sump ? Obviously it would take some planning and work but it's certainly possible!
Very interesting. I'd like to see more on what it takes to delete direct injection and how gen 5 motors handle boost. Keep up the great work!
jpprind thank you much!!
Why do you need to delete direct injection to use a turbocharger?
Thanks for making this pan. So glad you came out with one.
Awesome video and info. I think you should run the engine on an engine dyno and see the out put of the engine. It may produce similar or less or more power. If it produces similar or more power than you don’t have to go through the headache to design a new harness for the LT.
I'm watching with bated breath. My friends got a Hyundai Genesis coupe he wants to put an LS in. After seeing your Instagram post I've been trying to talk him into doing an LT. This video might be enough motivation. I can't wait to see what you do with the front sump oil pan. 👍
The Angry Mechanic Thanks!!
Only thing i don't like about cam swap on lt is you have to take off the oil pan
Amazing as always. Your kits are leaps and bounds above others on the market.
Thank you!!
For swaps that don't mind the extra weight, the new GenV L8T iron block and OEM forged stroker crank bottom end topped off with Gen3/4 Cylinder heads will be the ticket with the block only needing head dowels moved up/down to match the LS heads.
And its pistons
Amazing information. I've been planning an LS swap into my BRZ for a while now but have really been toying with the idea of going Gen V and swapping in an LT4. This video does a great job at showing a lot of the small differences I'll need to take into account if I decide to go for an LT instead of an LS. Pretty much buy a kit for LS or fabricate my own for the LT since no one is really making them for the 86 platform yet.
you prolly dont care at all but does anyone know of a tool to get back into an Instagram account??
I stupidly lost the login password. I would love any help you can give me
@Nicolas Achilles instablaster ;)
@Anakin Dean thanks for your reply. I got to the site on google and Im trying it out atm.
Seems to take a while so I will reply here later when my account password hopefully is recovered.
@Anakin Dean it did the trick and I actually got access to my account again. I am so happy:D
Thank you so much, you saved my account :D
@Nicolas Achilles Glad I could help xD
Very cool stuff! I have installed 2018 Gen V Lt in my 1948 Chevy 3100! Love all th video!
You have to stay still while videoing. Making pipes sea sick rocking back n forth
I see you used the gen 5 fuel injectors in this port injection conversion.
Just found this channel cool stuff with the conversion, subbed.
Me too was just sent a link from a gentleman I was having a discussion with about a front sump LT oil pan ! I didn't realize the oil pan mounting was different
holly crap this is exciting
Thanks!
Since the gen 5 heads will bolt to a gen 3 or 5 block, personally I would like to see a kit to adapt the high pressure pump to the gen 5 block as well. Gen you can have vvt and direct injection with a gen 3 or 4 long block.
Great Info. Thanks.
dan noyes 👍🏻
Wow thank you very well explaining
Lov the info
Perhaps a potential user of a Gen5 motor needs to know initially most of all is how does the Gen5 compare to the Gen4 in physical size when fully dressed.. Is the Gen5 bigger/smaller in length, width and height with all the accessories fitted including exhaust manifold, a/c, alternator etc? One of the great things about the LS was its small size compared to its displacement.
Hi have you made a front oil pan yet ?
Thanks
John
talk about detailed! Excellent video
SBC doesn't use a center bellhousing bolt, LS does
So you already have a harness for the 370z/G37 chasis
Cheap Intentions No, just a prototype.
Why go to the trouble and expense of getting a DI engine just to delete DI?
Mark G in this case it’s for r&d to install them into the Nissan cars without also having to worry about all the efi for now
A little feedback, I picked up a 2016 L83 out of a 1500 chevy and it does not have a power steering pump. Figured you would like to know.
Ricky McFarland there are plenty of mod shops like swap junky’s who offer a power steering and reposition of the alternator for engine swapping.
I think the real question is imo anyway , what is the actual advantage going to a gen 5 to begin with over an LS....
RelentlessRacing more power from heads, factory forged crank, piston squirters, etc
I also noticed that you didn’t do a dod delete and replace the cam lifters can this work ok being GM has a problem with that system
Don't the direct injectors require fuel through them to cool them down, won't just deleting them make them create a hot spot
Great video . Any update video on the twin turbo frontier?
Thanks! There will be updates in a few weeks. Needed to get a few other projects moved through the shop before we can get back on it.
So technically I should be able to swap my L96 6.0 block for a newer L8T 6.6 block in my restomod Regal. .......Or perhaps put an LSA blower on a 6.6 L8T motor and get Big boy power with Big boy torque. This logic should work if you can put LS intakes on the LT blocks, Right?
i bet that lt fuel pump is fun to have to change.
Have yall done any pulls on this motor yet with the factory gdi injectors installed in the bores the way it is now or did yall swap them for the plugs you mentioned before or planning to when the full dod delete is done? Apologies, if I missed it in the video. Reason I ask is those injector nozzles are pretty stout, but they rely on the fuel being injected for cooling and can and most likely will overheat if you push it. Papadokis racing did a similar test with a new gdi Honda, bypassed the gdi for port fuel injection and left the factory gdi's installed the exact same way and blew a nice hole out the top of one of the injectors. Lol Luckily, the intake was offset from the injector if I recall correctly and they didn't blow a hole in the intake as well, but could be a mess with this one if that happens. I'm sure y'all got it figured out, but figured I'd throw that out there to save on some wallet and headache just incase. I don't know jack crap about gen 4 and later models like yall, but I been tinkering with my gen 5 l83 since I bought the truck new in June of 2014 and been trying to learn all I could about it sense. Finally got the full 12000 page service manual from GM on the 2014-2015 models a couple years ago. Still can't believe how much goes into the design of these things.. If yall or anyone doesn't have it and need it, I can get it to you. No charge. It came on a cd, but I got it copied to a pdf on my drive. Not sure how i could send it, but I can figure it out if anyone needs it.
Cool! I just got a cheap L83 to play with and the adapter plates and LS7 intake showed up today. Wondering how tuning with the high compression and port injection will be...gonna have to cut some timing or go thicker head gaskets to lower compression.
They have the same compression ratio as the LS7, but the ability to cut more cylinder pressure with variable cam timing, so I think it will work great.
6.6 might have power steering on some big rig
Around how much is the cost labor whit all the parts need it . not include the engine??
Building my first l86 blower motor now and ya it is different but I really like it just a better engine over all. Much harder to source correct parts as guys will try to sell ya ls stuff and it won't work.
Good stuff lot of information.
Awesome content, one question though would a 6.6 L8T (gas)from a 2020 Silverado HD fit and work on a 2020 Silverado with L83? Thanks in advance.
Thank you brother for this information, I am wanting to install a Gen 5 LT4 in my 06 GTO and we all know that's a front sump pan car too,will you guys be developing a pan for this swap,or will a 350 z,or all the other front sump pans work? Headers too for the 06 GTO!
How hard would it be to swap a LT into a 2000 Silverado? Most people say just go with a LS, since it easier.
What adapters did you use for the cam, crank, and oil sensors with the gen 4 harness?
So is it possible to put a LS top end on a newer LT bottom end? I see bottom ends for sale and I already have a bunch of LS top end stuff
Hi, can you tell me if a LS dry sump block assembly will bolt in to a 04-06 pontiac gto?- the gto has a front sump.
Thanks for the info interesting
Where did you purchase the fully assembled intake ?
Why can't you swap to the LS oil pump and run a LS pick up
Good info..👍
have you found that the injectors are burning up with no fuel flowing through them to cool them? I saw on papadakis racing channel where they melted the injectors when using them as plugs.
Motion raceworks sells the injector plugs
So then this will work on the c5 fuel regulator?
I’m doing a 61 vette with a 5gen LT4 supercharged out of a 2018 camaro. I ve been told the 10 speed auto trans will not work without cutting up tunnel on car. Ive been told they like to use 4L70 TRANS for size reasons. And I will not have to modify tunnel.
With top mount bolt hole offset, will 4L70 trans bolt up otherwise?
Thanks
I wonder if someone has tried this on a big power camaro or corvette and use a standalone system, instead of buying a expensive billet intake.
Is there some one doing blank di injectors machine from steel, as i've been told the injector tips can over heat with no fuel flow and drop in to the cylinder mostly on big power turbo combos.
What are you doing for the oil pump solenoid? Are you leaving it simply unplugged and letting it run in the high pressure state?
Did you find a solution to this?
Can a L8T crank go into a Gen 4 engine, without mods?
Also I see they already make port converted l86 heads and lt2 intake for reasonable prices...
Good question
Great video.. Do you know what adapter is needed to put a 6l80 behind the l83? Thanks in advance..
None, those engines came with 6L80 transmissions. They bolt right up.
Ahhhyeah, it's happening.
Dry sump it already!!!
They make a iron block 6.6L gen5
do the gen5 pistons fit on gen4 rods?
Can this run on a gen4 computer?
Can i use the ls7 intake but keep the dod?
There’s a much better solution for deleting the direct injection injectors. Motion Raceworks has plugs that replace injectors.
I have a L83 and I’m searching for a budget oil pan for my swap. I’m installing the L83 in a third gen camaro is there any pan other then the expensive Holley? I actually found something on eBay I’m just not sure it will work based off what you explain, it’s listed to fit a lot of LS and the seller claims it will fit the L83 but you know how returning something online can go so I’m scared to spend my money.... any suggestions??? Also what about a fuel pump that will work? Is the Aeromotive 340 a good buy?
So does this mean you can Carburate a gen 5 lt since you can use an Ls7 intake
Yes
Will a holley efi hp system for a gen lV LS work on this combination
I would like to know this too!
I read that the l83/84 use a cast iron crank is that not true?
I’m sure you’ve figured this out by now since it’s been months but I’m finding that only the 6.2 motors have the forged crank. L86/lt1 have forged crank, lt4 has forged crank and rods, and possibly forged pistons not sure on that one yet..
Gen 4 cam fits in l83 block with correct alignment of lifters, no lobe for hpop if your deleting direct injection
, Gen4 heads WILL bolt on l83 block if you relocate dowels, upper 8 mm bolts would not be used,
Alignment of lifters, can you explain?
Jeffrey French Yes, lobes of gen3-4 cams align with the lifter holes in Gen 5 block. Same thing I said above.
@@petejoseph8257 ahhh okay I read it as it needed to be aligned, then it will work. “With alignment of lifters”, like that was an mod needed.
Thanks for clearing that up
So. If I have a gen 3/4 cam it will fit the l83 of course with out the direct Injection.
And they said there completely different motors ha
Trucks with gen 5 motor don’t have p/s pumps, not even 2500s
There’s several companies making kits that add p/s all the way to fully custom front accessory drives
Trey correct, but these engines never came with one installed from GM. I’m installing one as we speak into my 99 Sierra, I’m using the C5 accessory drive, LS2 water pump, L83 balancer.
I hear ya, and that means it’s not easy to get it done done cheaply lol Are you able to make a C5 pump work with your setup? The c5 drive all swap right over to your gen v?
Trey works great. Just waiting on a wiring harness to finish the swap, the wait is nearly killing me! Hahahahaha
stellingbanjodude Please post some videos when you get it all buttoned up man, that sounds like a sweet swap. Are you planning on racing? My 18’ double cab on 33s ran a a best of 15.4 with only a 87 superchips tune all stock otherwise. That 99 should be flyin with an l83. I’ve seen the single cab 14-18’ trucks run low 14s on tune only
Can put this motor in a 4th gen Camaro?
