The amount of power that is unleashed with that 14.5 PSI turbo-pressure, that's just insane.
Well, you're adding one full atmosphere at that level.
You should double the NA HP at that boost level.
So, it wasn't all that crazy...still impressive though
The top end flows very well. Doubled the output basically. Older engines typically need 2+ bar to do that. 😮😮😮
Great test! I have a 2021 LV1/8L90E set up with 2 miles on it (from a Express van) for my 87 Buick T-type (refuse to LS swap it)…Im glad there is finally some support …I am looking to keep the DI along with port injection (GM ECU/Holley EFI combo) Turbo (S476), ported heads with head studs and may do a rod/piston upgrade or just a ring gap (looks like the stock rods and steel crank should live to about 800FWHP) , I’ve seen the BTR Trinity GEN V Intake used on one of these (modified) looks like it works well….Great work SPDC👍👍👍
Question for you bc I’m considering doing something with my lv3, how do you figure that the bottom end is good for that extra horsepower?
@@mattferraro9124 well for starters it’s a mini GENV LT…so all the hardware, pistons, rods, valvetrain components cross over…the block has oil squirters, steel crank (despite having offset journals), 6.125” rod from the factory…in stock form with proper tuning I’d bet it would take 800hp …a rod and piston upgrade may push that close to 1000hp (crank and head sealing being the limit)….upgrading the valvetrain to take some rpm would help a stock bottom end live (limit low end power ) rpm would be your friend …lastly this engine plain and simply is way better than a built Buick V6 and we know how good those can be….
Now stock lv1 cam on 7 psi then 14 psi. Then stage 1 cam 7 psi and then 14 psi. Finally send me the engine with the stage 2 cam set up for my '98 Sonoma/Syclone...JS 😉🤙🏽
What I'm wanting to do in my 92 s10 might even just do a stage 2 cam N/A AWD as it'll make more then the syclone originally did at like 350ish hp and 350ish ftlbs
this is the V6 that should have replaced the 3.6 in the colorados. what a waste
Is there a complete parts/package i can buy to do this?
I wonder what tvs 1740 or 1900 supercharger kit would put down. It would be a mini-LT4.
that would be wicked cool actually. Id love this in a Old Regal / GN .. this motor is superlight too...great for a road race setup..sheeet this in a nsx would be ideal esp at 1 bar
Well, I guess when my old school 4.3 in my Syclone finally decides to take a shit I know what I'm gonna be putting back in there.
What I want to do with my 92 s10 xcab make a ohmage to the syclone with a Chevy counter part
this thing would be insane in a Pontiac Solstice GXP or Saturn Sky RedLine
Why not just use the inline? The LNF is good
Literally a LS V6...the perfect engine to swap into a 80's Regal and make a GNX.
Even sounds like a GNX...
LT based. But close enough.
@Ls1 1980cutty I remember the GN owner that did a LV3 swap with a cut Holley LS intake manifold and fuel rail. Really nice build
They machined these metal plugs to cap off the direct injection too. I thought it was all really cool stuff, and never thought id see a 4.3 swapped GN lol it made great power though
It seems like 8 cylinders r not getting much more torque out put than these numbers. I think this is alot more bang 4 ur 🤑👌
It would be really cool if someone adapted a TVS1700 or TVS1900 supercharger from a LT4/ LSA to fit the 4.3L V6 LV1/3. It would make for a potent compact package in Jeeps and compact trucks.
Does anyone make a proper intake for the LV3 yet? I swear ive seen a BTR intake for them but their site doesnt seem to show a high ram style yet. Asking as id like to do an LV3 swap on my Syclone.
@The1sunnydmusic Yeah, all those V6 trinity intakes were modified versions of the V8. I'm not sure they are going to make a production run, but you can always ask them.
Some guys in the LV3 swap facebook group might be willing to either sell their modded intakes, or make one for you. Otherwise, a ported version can be an improvement.
Can you send me the exact name of the parts you used? I mean the ls3 intake and the ICT Billet adapter
They're in the video description with links. The LS3 intake is no longer in production.

Did you increase ring gap? What is the stock ring end gap?
@aaronkrummrey9406 no. Stock ring gap.
No idea what stock gap is.
i wonder how long this would last daily driving on a stock bottom end,ive got a 2016 silverado that would be perfect for this.
WOWWWWW!! Love to have this in my 02 blazer ZR2 5speed, it would be absolutely insane!! Nice work 👍
THANK YOU SO MUCH. I AM SO IMPRESSED!!! THAT 4.3 IS A TOTALLY AWSOME BUILD!!! GREAT VIDEO AND A GREAT BUILD. THANKS FOR SHARING. PERFECT FOR ANY DAILY DRIVER.
I think this would work well with a 6 speed Allison transmission from a chevy 2500, and I would put no less than a 6L90 behind it if its going into a silverado 1500.
Allison 1000 would be a waste. They don't spin high RPMs with them. Everything an Allison 1000 has been behind doesn't spin past 5000rpm including the Vortec 8100 big block which was found in front of the 1000 series from 2001-2007. A build 6L80 or a ZL1 spec 6L90 would be more than enough behind a 6000-700hp 4.3 LV3.
iTs jUsT a VeE 6 duuhhhhhhh 🤤
Might be the first time (in .... idk ... 70 years?) that a 6000 rpm motor has been called a 'screamer'.
But I still want one.
This in an S10 soon for me
Have one of those stock, really smooth runner compared to the also good Vortec 4.3. Shame nobody really bought them and it’s now it’s been replaced in a truck with the 2.7L 4, which might be a good engine too but I have doubts about its long term durability
I think it'll get to 300,000+. They built that 4 banger like a diesel
A little complex of a design but a good one
It would be great if there was a complete kit that was bolt on. Or a centrifugal procharger kit. They make em for the v8. How hard would it be to make one for the V6.
What Stand alone engine management system could/shouldvyou use with a 4.3LV3?
I want to pair it with a 4L60e 4x4(also needing its own standalone management system) and drop it into something it never came it 😂
This is awesome. Great engines and I'm hoping they get some more support. I'd be okay with putting one in my old firebird
Same but with my 92 s10 and find a way to awd it
These guys have helped me a ton with my build, (2014 Silverado). So far ive done forged internals from the 5.3, stage 2 cam with ls7 lifters , catch can, cold air intake and DOD delete and im still working on an allison swap from a built 6L90, still factory 3.23 rear.
Stock intake manifold?
@@OBSityproblems Yes still factory intake manifold, not entirely sure if I want a low rise or high rise
It's a truck. So high rise is better for low end torque isn't it?
@@craigquannThat's what I'm gonna end up going with, any recommendations would be appreciated as I'm doing this by myself
@DoubleTrouble4647 I'm not certain. But I think BTR makes a high rise intake that works well. It's also one of the few v6 options. But how much do I help over the factory intake, I have no idea. Nor do I know it's even worth replacing the factory one as it's supposed to be pretty good.
a short runner manifold will help flatten the torque curve. It also reduces the likelihood of knock. A dual plane would be cool too.
Is anyone else having trouble finding turbo headers for their 4.3?
Because (so far) they don't exist at the moment. All the turbo cars w/ the LVx stuff are using custom made headers or using the stock manifolds like we did.
No, auctually I can find them super easy.
Me as well
Make em, or if your skill level isn't up to fabricating headers, Have someone make em for you, probably gonna be little pricey tho.
Im turboing my truck😂😂😂
I'll sleep better tonight knowing that, Thank You.
Are there off the shelf DIY kits actually available? Does anyone make a full kit with instructions that's basically a factory bolt on? Single turbo kit, intercooler, piping and tune that gets you 400hp at the wheels. And it has to be daily driver/work truck/towing friendly. Bonus points if it doesn't require opening up the engine.
Unfortunately no, there is not a full turbo kit available at this time.
@@Sdpartscenter do you think there ever will be?
Awesome!
But got to ask! What on earth kind of intercooler is that? Is it what I think it is? An aluminum radiator customized to work as a water cooled IC? If so, Awesome! Been thinking about it for years but newer came close to actually doing it :D
It's a water to air intercooler from shearerfab.

Anyone making something like this for rhe 2015 to 2018 4.3 in silverados ?
As far as turbo kits, not that I know of. It would be super simple for somebody like Armageddon or On3 to mod their V8 kits to work though.
Curious if this would work for my 2020 Chevy Silverado. I have the 4.3L v6 EcoTec3. Looking for a turbo for my truck but the only thing that pops up is the Vortec. Can anyone help??
It'll have to be a custom kit.
There is an LV3 performance group on Facebook that might be able to get you squared away.
Lol.... that's sick!!!!!
so you going to sale this to me or not?
Im curios how this setup would run in my 96 S10?
Like a striped ass ape! You better have put as much money in that suspension and helmet.
What internals did you go with?
That was stock internals.
We have some forged rod and piston combos coming soon.
@@SdpartscenterNo way! what electronics did you need for it? im thinking about swapping a LV3 into my 02 Sonoma Crew Cab for newer programabiltiy for forced induction and cams
@Sdpartscenter it made that much on stock internals? I have a 98 4.3 s10 I'm thinking about turbocharging
Can this be swap out for a gmc syclone
@@goozy808 I'm thinking of putting it in my c5 6spd.
Could i do this to my gmc acadia?
You'd have to run a custom turbo setup, but I believe the Acadia runs a 3.6L V6 instead of the 4.3L.
What torque converter would you use for this set up with a 6l80
Or better yet, a 4L60 ????
for the stage 2 na set up he said min of 2500 stall, prob 3000 stall so id imagine a 3000 stall billet converter
@@josephoverstreet5584 I bought their dod delete kit with stage 2 cam and did a couple other mods but my tranny didnt last a week 😅 now in the process of getting a new one
this in a lifted silverado with long travel suspension would be a total raptor killer! wimpy lil 3.5 ecoshit got nothin on a turbo 4.3!
This in the ass end of a Pontiac Fiero ;) I already pulled my 4.3 from the donor S-10. Happy turbo noises coming from a small mid-engine car from the 80's with pop-up headlights...
what do we know for a chevy express 4.3l lv3 2020?? Anyone trying to build this ?
Chevy Express should be LV1 non-dod/afm, people are building them already.

Can I put it in a stock 2002 Chevy S10?
How you make the ls3 v8 intake work? I saw the adaptor plates are for a v8 to, I know they can just be cut. But ls3 intake modifications?
We used an adapter plate from ICT Billet and blocked off the back ports. It's covered a little more in the longer format video because we had to run LT1 V8 headers on the NA cam comparisons.
It was all down to time constraints or it would have had a better finished solution.
Would this work on the LU3 4.3 v6
Sorry, no. Completely different design.
That make my heart beat.
I’ve been wanting to build my 14 rcsb lv3 for a while i’m thinking about running your stage 2 cam with seven psi of boost, but what about the fuel system ? Can I use a better injector from the V8 LT motors?
Yes, you can use the high pressure fuel system off the LT engines.
@@Sdpartscenter thank you. I’ll be calling you guys soon to order the parts.!!
That thing will take 13lbs on 10-1 pistons if the timing is right.
Stock pistons and connect rods?
Correct.
Can you put a turbo on a 4.3 ecotec motor? I keep seeing the vortec motor mentioned.
This is an Ecotec. The 4.3 vortec search results are overwhelming.
You can put a Turbo on basically any engine.
Does anyone know where to get the turbo headers or turbo kit?
This was a quick one-off for the dyno. You'll have to find somebody to fab one up or DIY.
Factory truck manifolds flipped around
What turbo were you using?
Just a freebie off the shelf of Kurt's garage. Not an optimized turbo and probably ly a 15 year old design.
@Sdpartscenter that's really impressive!
What standalone harness and computer did you use to turn it on and the year?
We used a holley dominator and an LS harness.
@@Sdpartscenter thank you, what year was that mottor?
@@Sdpartscenter can my oem computer be flashed/tuned or do you need to upgrade to holley dominator? Sick build! Thanks
Sounds horrendous
Agreed… that’s the sound of efficiency.
@@donovanmonroe2080 Not really its a 2v engine, any inline 6 dohc engine with 4v's is far more effecient and sounds miles better.
@@thewraith6360 All that aside, 2.6 HP per cubic inch is insanely efficient.
@@donovanmonroe2080 Vortec 4200 has made about 1000hp to the crank with about the same mods, cost around $400-$600 for a clean 4200 and the cheapest lv3 by me is $3k and sounds ALOT better and its lighter.
@@thewraith6360 Have you heard modern BMW turbo i-6 engines? They sound awful.
Now do a LU3
Would be nice to see what the previous Gen 4.3 can handle.
Can I use the same parts for my 94 v6vortec engine
Unfortunately no, this is an entirely different setup.
Yours is SBC based (vortec) and this one is LS based (ecotec). Unfortunately not
@@collinklitz7434 this one's actually LT based. Direct injection and all
So disappointing to see these big money big name companies being so inept at building engines. I mean seriously what is this abomination? An LS3 intake hanging off the back of the motor? Port injection? New ECM? Jeez guys gain some brains and make the stock stuff work, all you need is a cam with more and bigger lobes for the high pressure fuel pump and some tuning on the stock ECM.
Hi Rindo, so in our longer video we go over the reasons why we did what we did with the hodge-podge mess of LS3 intake, port injection, etc but I'll be glad to enlighten you.
We had 2 days to get this done as it was the only open slot between customer engines. It's a customer engine validation tool first and once in awhile we get to run some R&D components on it.
Because of that, we had zero flex-time to try and make a stock pcm run in standalone let alone play nice on the dyno. So if it wouldn't fire up, or limited rpm/throttle because it didn't see a specific module or signal, the whole session would be toast. We didn't have time to work with the Gen V LT's parameters especially with max torque and driver demand. Our guy in house that tunes the Gen V LT stuff was going to be out of pocket that week as well. We were even on the horn with our contacts with Holley to see if there was any possibility to run their GDI controller on the V6 but that was a non-starter. If we had two weeks of open dyno time to make it play nice, we would have.
What we did have was the stuff to make a port injection setup work and we've run multiple Gen V LT V8s in that format problem free.
Main goal was get the NA cam comparisons between the Non-afm cam and our two performance grinds, adding the turbo kit was just icing on the cake of "if we make the first part work and have a little time to play."
Here's the longer process here, enjoy the V8 LT headers with the capped off unused primaries: ua-cam.com/video/koAvUM4wVcQ/v-deo.html

Idgaf what kind of time or parts you had to work with, that’s some impressive ship! Well done!
@@Sdpartscenter Rindos Rides knowledge level is that of a queef, in your hurricane of make power know how. Awful nice of you to even bother with a reply.
Were's your big power / stock E92 controller / stock injector 600+ HP LV3 bud ? It ain't here on UA-cam is it ?
@@jamesgeorge4874 the point was that this is the only place you will see such a mess of an engine. The E92 is used on all the gen V LS stuff, of which you can find plenty of people doing turbos and such with on UA-cam. This stuff has been around over 9 years! Which is my point, these guys had 9 whole years to figure out gen V stuff, and instead they do this crap. Who else would ever do something so ridiculous? You going too do this to an lv3 you own??
very disapointed
