Bought a 2016 Silverado back in January. Now, before I made the purchase I did some research on the difference between the V8 and V6 models. I was absolutely blown away by the power these new 4.3's are making! So, I saved 3k$ on the truck I bought vs the V8 one and took it to Montana this summer with about 700 lbs of stuff in the bed including my sportster. Did friggin great man. Anyhoo, I have an 88 s10 that I plan on doing the big "LS swap" into, and I think I've pretty well changed my mind on that😁 I even have a supercharged 3.8 out of a gtp that I planned on using, but now, the lv3 I believe will be the new small motor of choice for swaps and hot rodders. Thank you so much for doing the r.n.d for getting some great power out of these V6 monsters!
More cam! More valvespring! More turbo! 730ft/lbs tells me there's a whole lot left in the horsepower department. I bet 800 is easily done if you get a bigger turbo to carry the boost out along with a bigger cam/valvespring.
Just finished the vid, and I gotta say one more time; thanx bro, these lv3's are absolutely amazing. With the lawsuit against g.m, they should just get ahold of you guys and make y'all rich n have you patent a new dod delete for all running Chevys n GM's on the road today. I believe the og ls has found it's match. I have 5 old school vortec 4.3s at my shop and they are just hanging around, being 37 and seeing how far they've come is quite the story. Keep up the good work! Let's see what the lv3 V6 is really capable of😁
That sounds nuts to get rid of the original powerplants? Why not just swap a Blazer/Jimmy or S10 rather than mess with those rare vehicles like that. Man GM guys went silly in a bad way if they're LS swapping those.
So it's ok to swap the original vortec v6 to the totally new generation 4.3 v6 but not a v8 LS? This is not the 200hp vortec v6 which came in Cyclones and Typhoons.
This engine came out right after I built my stroker 303 cubic inch 4.3 V6 back in 2013. The LV3 V6 runs as hard on the Dino as my stroker even though mine’s NA. My stroker 4.3 is running a forged 30 degree evenfire Scat 3.875 inch stroke crankshaft. H beam rods, forged pistons, 4 bolt mains, Brodix aluminium heads with a bolt pattern the accepts a tbi or cyclone intake manifold. It’s pushing 320hp with a 454 tbi. The torque is crazy. Can’t wait to put a marine 4barrel manifold on it with a Holley EFI. The LV3 has a lot of potential, imagine it with a custom stroker crank?👍
It seems we have a lot of work to get power out of the 4.3 vortec. Is a marine intake and a carb be helpful with a cam. I’ve haven’t heard anything good about cams on these engines. The only easy rout I see is nitrous. I wouldn’t mind a 50-75 shot I have an 02 2 dr extreme but I have to redo the whole exterior and interior…. They stole it messed with it inside and out then stole the cat and crashed it… so many tickets and a beat truck. I will restore it get a race cat maybe a new bed and new sound system. Insurance gave me $4000 for the whole thing prob need 1000 to make it cali legal but with $3000 and lot and lots of work I will be a make it better than before….
I'd like to see a bigger stroke crankshaft for these. Imagine getting almost 6 liters of displacement out of a V6 platform. I'd like to see more stroke and a dual plane intake with a blow through EFI on a forged rotating assembly. Imagine the torque a dual plane intake would enable especially on 14.5 psi. Imagine 700hp and 900tq in a all wheel drive vehicle. Wish you guys would of ran the graph from 1500-6500. I'm curious of what it made down low.
I wish I saw this 5 years ago. Before I bought a new or rebuilt V6 in my 86’ Grand National. I think I paid around 14K for it. With a newer ball bearing turbo and it made almost a thousand hp on 13 psi
Looking at putting that in a 96 s10 blazer. Seeing at least some support of the platform is making me believe it's possible to do. Even just headers and stage 2 cam would be a huge upgrade over the tbi 4.3 it's running. Great work.
Not a bad choice, especially when there's performance parts available. The heads are so good, a cam (and possibly turbo) is all you need. I'm really impressed by the torque production throughout the rev range. Nice work on the cam design!
That's about right for 14.7 psi of boost. Normally you get close to doubling NA power numbers with 1 atmosphere of pressure. Good stuff guys! You have the best job ever!
Great video! I'm doing a bunch of reading about these little motors and I think I love em. I'm glad to see an aftermarket developing for them too. Now I just need one for myself...
I have a stock 4.3 is a Suzuki Samari that is lengthened, and I need sandbags and lower psi in the back tries to keep them from slipring. It is fun to drive a vehicle that requires a little finesse
I have an idea for a custom cam spec for you guys to consider with the LV3 engine. So, basically, keep the intake centerline at 107 degrees no matter what (with 0-deg cam adv or ret), then make the LSA either 107, 108, or 109 depending on if it's for 10-10.5, 11-11.5, or 12-12.5:1 compression, respectively. Basically, for every point of compression, you want a change of about 1 degree LSA, but the intake centerline is based on the cylinder volume compared to valve size, so unless you bore or stroke it (and somewhat significantly, at that) or significantly change the valve area, that should stay about the same. Then dial in your duration to have a total overlap at the advertised duration lift of 20, 40, 60, 80, or 100 degrees of overlap. Those will be the "stages" and will determine streetability vs peak power production. Obviously, the first one with only 20 degrees of total overlap at the advertised duration (measured at .006 lift, AFAIK) would be the most stock-like in terms of rev range and idle. It'd be, essentially, an optimized towing cam. The 40 would be a mild street cam that could still be used for towing. I suppose you could call it a "hot truck" cam. And so on. Then just dial in as much lift as you can with either of those to manage piston to valve clearances. Also, any heads you make, focus on keeping the combustion chambers as small as possible (so people don't need high dome pistons, which messes up the quench) while unshrouding the valves and smoothly shaping the bowl(IDK as much abt this yet). Also, go a step further and add another angle to the valves, making the seats 30 degrees instead of 45, and then stepping up to 45, 60, 75, and so on as normal. Lastly, for your port work, do what David Vizard teaches in all his books and videos. If you can do that and manage to offer sets of heads for under 1000, you'll have the best LV3 shelf parts on the market.
That's unfortunate. There are some of us that actually are happy getting to mess with this engine. A few of us have a good bit of history with modding the GM V6s.
If I hadn’t already LS2ed my 2000 Extreme, this new style V6 “buggin half dozen” would be sweet with a turbo, with gapped rings and all. Thanks for the info.
I figured Borg Warner's 64mm compressor works super well with this engine and should hit 700bhp. The ebay GT-45 turbo is $168 and is good to 700hp too...
61mm is very popular with Grand National/3800 engine builds. 63.5mm is ideal for the 4.3 at the 650 bhp level. Big block torque from a lightweight V6 :D It's amazing GM didn't think to turbocharge it from the factory.
Inspired, makes me want to just put headers and run a little boost on e85 call it a day. Already did the AFM delete motor runs a whole lot better since I did that. Impressive power out of that motor!!
My dream build would be to put the lv1 with a 5 speed in a 1980 monza spyder. I also think the lv3 or lv1 should be a v-6 option for the chevy colorado.
Gonna try and build one of these for the drift car, keep it light 😁 fantastic information 🙏 hopefully you didn't waste Too much time making the video to share it 😅
The lv3 is like a 5.3lt with two cylinders chopped off not like the 1st sbc or 2nd gen vortecs like yours so this cam wouldn't work nor would it specd out the same for your vortec because the lt heads way outflow the vortecs so the only way a cam with those same specs work is if you had the head decked slightly, ported, cold air intake with k&n, and full exhaust with a tune and it'd still probably be a little too big. Not saying you couldn't upgrade to a good cam that would work with your set up either just not one this aggressive..
@zachniverson8816 I think he meant the entire motor ,cam, and turbo. I had a 600hp Syclone back in the day. 100lbs off the front would have been fantastic.
I have a 2007 4.3L V6 that I'm thinking about putting in my son's 1985 Vette, with a GT35 I think we could easily be into the 500HP range and getting fuel mileage and not blowing up rear differential, sounds like fun to me
Water/meth doesn’t help make power, Yes I said it! More engines have been destroyed by “ hydraulicing” a piston then you can believe. Now E-85 is a different animal and you can gain several horses just switching to E-85 and tuning accordingly. Can’t wait to see what you guys have in store for the V6. Finally the GM V6 is getting some love. And rightfully so.
Seen some turn key in stock form for sale been thinking about putting one in my 92 s10.. Would need a new diff as it's got the little 7.5 inch diff might leave it in just to grenade it lol
He mentions there is a V6 header that is the same as the LT V8 egines, but it wouldn't fit around the dyno, does anyone know which car/engine that came off of? I think it would work for me.
Made the idiotic mistake of rebuilding the stock 2.8L v6 from my ‘88 S20 Blazer during COVID. Put a 3’ lift/leveling kit running 31” tires on it. With a mild cam and 3.42 gears we’re getting 10MPG. Have been thinking about an LS swap (more power and efficiency hopefully getting MPGs up to a reasonable level), but this makes WAY more sense then fighting the tiny engine bay with 2 extra cylinders. Stage 1 cam and have some fun!!
I would drop the compression, stage 1 cam, fab up a long runner manifold, run a similar sized turbo, and a hell of a cooling system and put it into a dually. Big block power that you don't have to pay for when you're not using it. I don't think it would ever be a mileage master, but high teens, low 20's (not towing/ hauling) could be possible- and sounding like an old 2 stroke Detroit would be pretty awesome (IMHO).
Thanks for a great video I appreciate that. I have a 4.3 in my GMC Sonoma yep its the older 4.3 I've thought about trying to put the newer LV3 4.3 in my truck 🚚 but I'm not sure if I want to because I'm not sure what would be involved to do it. Anyway I'm going now and again thanks for all the testing you did.
I've been researching this for my truck for a long time. LT adapter brackets should bolt it right in, same bellhousing pattern minus a bolt, if you wanna keep direct injection you'd need some help tuning the stock computer or you could convert it to multi-port like they did. Dropping it in and not touching it you're already faster than a GMC Syclone so it all depends what you want from there.
@@raystevens687 Not a problem. I know it was kinda open ended but beyond putting it in the truck it's down to personal preference. You can stick a 4L60 behind it and cruise as it is or go nuts and put a 6 speed manual and twin turbos behind it. The sky is kind of the limit since they share many components with the LT. It'll take some fabrication skills to either build or cut down and re-weld V8 bits where no one has come out with a part yet. Moroso makes oil pans for them now but I'm not sure about anyone making intakes yet. Jost Performance stuck one in a Grand National and cut down a Holley Hi-Rise for it. It's on here if you wanna look it up
Yes, we did lock the phaser out. We couldn't control any VVT sweeping with the Dominator. There are definitely gains to be had, but in the essence of time, it just wasn't in the cards for us.
I only see three spark plugs, looks like they found a pair of sbc long tube headers that bolted up. No since in cutting that 4th exhaust of just for the test. They could use those headers on another build/dyno
Now that was impressive for a v6. I got to see several time the Typhoon and Syclone track tested while under development at my local drag strip, and they were impressive. My V8 88 S-10 Blazer, or better yet my 75 or 79 Chevy Monza would love this setup. What PCM/ECM did you use to drive the electronics? I'm going to have to look into this much more closely!!!!
Mike, we ran a Holley Dominator for simplicity's sake when on the dyno. We didn't have time available to work with the stock pcm in a standalone harness if we had to troubleshoot DTC's and anything else the pcm might freak out about. This is one of the big reasons why we had to run an LS3 intake with the adapters so that we could run port injection in an easy format.
@@Sdpartscenter Thank you very much for the reply. I just stumbled upon the v6 videos, and it looks remarkably do able from what I saw. The cam1 and cam2 versions would be great in my 75 Monza 2+2.My 79 Monza 2+2 with 130 hp 305 weighs 2950. My 75 with 340 hp v6 would be 200hp more and minimum 200lbs lighter. I got to dig into this combo of v6's this might just be the ticket for something old with something NEW. Thanks.
The older ones where small block chevys with two cylinders cut off, this is the same, LT (gen 5 small block) minus two cylinders, if an lt can be bolted onto an SBC trans then yes, otherwise you'd have to either swap the trans as well, or get an adapter to connect this to your stock trans
I have a 64 Willy's M38A1 with a Buick Oddfire V6 that I've been planning on stretching the body building a custom frame dropping it to the ground and stuffing an Aluminum 5.3 in. But now I'm thinking EcoTec3 V6 😎😎🤣🤣
Are the Piston Rings gapped to prevent a COMPLETE DISASTER with that TURBO… If it’s not gonna be TURBOCHARGED and it’s just for testing…it’s still a serious risk and the extra gap helps prevent the rings from pushing outward and well it’s all down hill from there
I would love to see this engine with the stg1 cam and 2 cheap gt35 turbos set to 7lbs of boost through a dual 3 inch exhaust in a 2014 chevy 2500 with a 6L90e transmission.
I have a 2000 blazer exstream id like to put the (#4) set up in. I posted a comment in a older feed. So I'll start again. Do you guys sell the whole thing as a drop in kit ? Or just the parts kit and recommend turbo? Also what year truck or Express van, should I get the 4.3 lv3. It will be very helpful when I call u-pull-it and try and find one or 2 of these things. Thank you!!. For your time.

Thanks for ALL the hard work making this happen.
All VERY informative and entertaining. 👌😎👍
Good swap option for an S10 Blazer, better towing and mpg
Just finished the vid, and I gotta say one more time; thanx bro, these lv3's are absolutely amazing.

Hopefully this will sway Syclone and Typhoon owners bit by the horsepower bug to keep it V6 which was the vehicles whole claim to fame.
That sounds nuts to get rid of the original powerplants? Why not just swap a Blazer/Jimmy or S10 rather than mess with those rare vehicles like that. Man GM guys went silly in a bad way if they're LS swapping those.
@@Arrozconchopsticks Ya they're even LS swapping Grand Nationals. 😑
Swap base models, nobody cares.
@@Sir.VicsMasher they must be too rich or restoring a beat car
So it's ok to swap the original vortec v6 to the totally new generation 4.3 v6 but not a v8 LS? This is not the 200hp vortec v6 which came in Cyclones and Typhoons.
This was jam up content , love the transparency and honesty. Keep pushing to use the dyno and you will be able to by your own soon
This engine came out right after I built my stroker 303 cubic inch 4.3 V6 back in 2013. The LV3 V6 runs as hard on the Dino as my stroker even though mine’s NA. My stroker 4.3 is running a forged 30 degree evenfire Scat 3.875 inch stroke crankshaft.

I'd like to see a bigger stroke crankshaft for these. Imagine getting almost 6 liters of displacement out of a V6 platform.
I'd like to see more stroke and a dual plane intake with a blow through EFI on a forged rotating assembly. Imagine the torque a dual plane intake would enable especially on 14.5 psi. Imagine 700hp and 900tq in a all wheel drive vehicle.
Wish you guys would of ran the graph from 1500-6500. I'm curious of what it made down low.
Lemme tell ya, I gave a lot of thought to the old s-10 in the back yard during this video
That’s exactly what I’m thinking
Would love to have one of these in my $650 Jimmy. Seems like the perfect swap for the S10 platform.
Love what you guys are doing with the V6!
I wish I saw this 5 years ago.
Before I bought a new or rebuilt V6 in my 86’ Grand National.
I think I paid around 14K for it.
With a newer ball bearing turbo and it made almost a thousand hp on 13 psi
Very inspired and educational. Nice work.
That is an insane gain. And the extra 100 lbs lighter than an LS up front in an S10, that truck would stand up on some sticky tires.
Looking at putting that in a 96 s10 blazer. Seeing at least some support of the platform is making me believe it's possible to do. Even just headers and stage 2 cam would be a huge upgrade over the tbi 4.3 it's running. Great work.
Love this v6 content. I'm thinking of doing a build
Im a jdm guy but just got me a chevy s10 with the vortec now ima have some fun with the little v6💪🏼
Not a bad choice, especially when there's performance parts available. The heads are so good, a cam (and possibly turbo) is all you need. I'm really impressed by the torque production throughout the rev range. Nice work on the cam design!
I think the rockers would struggle with a turbo
I'm thinking of getting the stage 1 cam you think with a stage 1 mpg will stay around the same ?
New plans for the S-10 Blazer lol. I want this!
Cool thx for the info, when my 01 2 door Jimmy's 4.3 goes I'll just put the newer 4.3 in it
That's about right for 14.7 psi of boost. Normally you get close to doubling NA power numbers with 1 atmosphere of pressure. Good stuff guys! You have the best job ever!
Excellent job, I enjoyed the whole thing!!! 👍🇱🇷
That way exceeded my expectations.
Great video! I'm doing a bunch of reading about these little motors and I think I love em. I'm glad to see an aftermarket developing for them too. Now I just need one for myself...
I want to put this in my 1970 MGB!! the 4.3 has always been my favorite V6. My dad had 350k on a GMC Safari and sold it running strong.
I have a stock 4.3 is a Suzuki Samari that is lengthened, and I need sandbags and lower psi in the back tries to keep them from slipring. It is fun to drive a vehicle that requires a little finesse
i kinda want to fit one of these into a subaru. replace the finicky boxer, gain oodles of torque, retain AWD. would be a pretty slick setup.

My 82 delta 88 coupe would be a great home for that with the turbo.
Do the head work next put valves, springs, retainers, and port and polish them and of course put valve guide seals on them
It's S10 time! What a killer setup!
Holy shit Thats a lot out of that 4.3 motor geez Louise but how long will it live

You got my attention now .I got a 1995 S-10 blazer Would love to install this engine with turbo.

It’s also nice to see you could technically buy used v8 headers and intake, modify it and it will work.

Amazing little 6 pack
Loving it Nick !
I was thinking this would be a better swap for a miata. The weight is really low and the lower torque and vehicle weight wont grenade a T5Z.
I wanted to swap the LV1 into my RX8 back in 2016. It has double the torque...

I'll sell you a sweet running 03 LU3 4.3 vortec
Thats some crazy power and tork. I heard this other guys V6 same motor and it sounds like a V8
Now I want to pull out my old track t and swap in a new 4.3.
I would drop the compression, stage 1 cam, fab up a long runner manifold, run a similar sized turbo, and a hell of a cooling system and put it into a dually. Big block power that you don't have to pay for when you're not using it. I don't think it would ever be a mileage master, but high teens, low 20's (not towing/ hauling) could be possible- and sounding like an old 2 stroke Detroit would be pretty awesome (IMHO).
Thanks for a great video I appreciate that. I have a 4.3 in my GMC Sonoma yep its the older 4.3 I've thought about trying to put the newer LV3 4.3 in my truck 🚚 but I'm not sure if I want to because I'm not sure what would be involved to do it. Anyway I'm going now and again thanks for all the testing you did.
I've been researching this for my truck for a long time. LT adapter brackets should bolt it right in, same bellhousing pattern minus a bolt, if you wanna keep direct injection you'd need some help tuning the stock computer or you could convert it to multi-port like they did. Dropping it in and not touching it you're already faster than a GMC Syclone so it all depends what you want from there.
@@connorbosworth7318 thanks for the information I appreciate that.
@@raystevens687 Not a problem. I know it was kinda open ended but beyond putting it in the truck it's down to personal preference. You can stick a 4L60 behind it and cruise as it is or go nuts and put a 6 speed manual and twin turbos behind it. The sky is kind of the limit since they share many components with the LT. It'll take some fabrication skills to either build or cut down and re-weld V8 bits where no one has come out with a part yet. Moroso makes oil pans for them now but I'm not sure about anyone making intakes yet. Jost Performance stuck one in a Grand National and cut down a Holley Hi-Rise for it. It's on here if you wanna look it up
Turn key crate motor $$$ EFI ? turbo needed for the over 600 hp specs . Is a 4L60E transmission worthy?
Recommendations?
I ran 15 seconds in the 1/4 mile at 4,000ft elevation. Everything stock and full weight, on a 91 tune. RCSB 2017 silverado.
This is great! Awesome video.
Way more entertaining than any Holdner vid. Great job!
BTW, did you lock out phaser?
Yes, we did lock the phaser out. We couldn't control any VVT sweeping with the Dominator. There are definitely gains to be had, but in the essence of time, it just wasn't in the cards for us.
Richard Holdener has a different approach
I love that these motors are LT based. I want one in a 3rd gen
3rd gen F Body?
@@kevinjokipii4260 Yes
I like to see a bigger turbo , its gotta hit 1k hp. In a syclone, or typhoon. Damn, track hawk what???
As far as I know, my 5.3 from an 04 GMC produced 295 hp stock. This thing made 318 hp stock?
the engine has direct injection, 11:1 compression and flex fuel capability from factory, thats why
My 90 S10 only had 160hp and 230trq i cant imagine how many speeding tickets i would have got if i had that kind of power 30 years ago.
I would like to know how much that motor cost
Great tests. Even in stock form, it sounds like something that would be good in my 2500lb Fiero.
I'm thinking of swapping an LV3 into a 4th-gen Camaro. Will the stock truck intake manifold fit under the windshield cowl?
Awesome video! hope you keeo making more like this!
Why does it look like there's 4 exhaust tubes on that header?
OK, I get it now that I watched the entire vid
I haven’t finished the video yet but said they same thing lol
I only see three spark plugs, looks like they found a pair of sbc long tube headers that bolted up. No since in cutting that 4th exhaust of just for the test. They could use those headers on another build/dyno
😮😮😮 that would be awesome in a Pontiac Solstice or a Saturn Sky Redline😮😮😮 at a snail to it oh crap!!!!
This is what I should swap into my 92 Typhoon and keep it v6 🤔Much better numbers than my stock Vin-Z 4.3 with 15psi is producing I bet!
New, your 4300 Turbo was rated at like 280bhp and around 350 torque. A new LV1 4300 with a nice single turbo and FMIC would be over 490bhp Net.
don't ever hack up a numbers matching typhoon or cyclone....are you crazy?
Sell it and rebuild a clean base model to your liking. Make money while getting what you want 🤷🏻♂️
Have 67 mustang….this engine with vs racing 78/75 2.5.
Now that was impressive for a v6. I got to see several time the Typhoon and Syclone track tested while under development at my local drag strip, and they were impressive. My V8 88 S-10 Blazer, or better yet my 75 or 79 Chevy Monza would love this setup. What PCM/ECM did you use to drive the electronics? I'm going to have to look into this much more closely!!!!
Mike, we ran a Holley Dominator for simplicity's sake when on the dyno. We didn't have time available to work with the stock pcm in a standalone harness if we had to troubleshoot DTC's and anything else the pcm might freak out about.
This is one of the big reasons why we had to run an LS3 intake with the adapters so that we could run port injection in an easy format.
@@Sdpartscenter Thank you very much for the reply. I just stumbled upon the v6 videos, and it looks remarkably do able from what I saw. The cam1 and cam2 versions would be great in my 75 Monza 2+2.My 79 Monza 2+2 with 130 hp 305 weighs 2950. My 75 with 340 hp v6 would be 200hp more and minimum 200lbs lighter. I got to dig into this combo of v6's this might just be the ticket for something old with something NEW. Thanks.
Can u put a 2021 4.3 ecotec v-6 in a 1993 s-10 standard 5 speed manual transmission
What I wanna know too would be sweet in my sonoma
The older ones where small block chevys with two cylinders cut off, this is the same, LT (gen 5 small block) minus two cylinders, if an lt can be bolted onto an SBC trans then yes, otherwise you'd have to either swap the trans as well, or get an adapter to connect this to your stock trans
This would be stupid fun in a little flat fender jeep or a 280zx
Wj with traction control
I have a 64 Willy's M38A1 with a Buick Oddfire V6 that I've been planning on stretching the body building a custom frame dropping it to the ground and stuffing an Aluminum 5.3 in. But now I'm thinking EcoTec3 V6 😎😎🤣🤣
how much would it cost to put a turbo and stage 2 cam on one? also how will the engine hold up over time? im thinking on doing it on mine
Will these engines work with the th350 transmission or power glides
Thanks I was about to purchase a 2015 Silverado and it has the 4.3
How can we get the higher torque lower in the rpm range.......think rock crawler....
Good wastegate control, turbo selection and maybe some time finding the sweet spot on the cam sweep with the VVT.
Why are there 4 header tubes visible on one side of a v6?
We explain why in the video. Short time, not enough time to make custom dyno headers.
I had the same question. Just didn’t scroll down far enough. Lol
Chris Forest put a LV3 twin turbo into a 987 Porsche Cayman. I am interested in doing the same. 800+HP on e85
Yup, we know of that build, friggin awesome setup.
Wow this is cool hope to see more people building these
What is the bore and stroke? Is it different than the old 4.3?
Bore 99.6 mm (3.92 in) x Stroke 92.0 mm (3.62 in)
LU3 was Bore 101.60mm (4.00″) x Stroke 88.39mm (3.48″)
Are the Piston Rings gapped to prevent a COMPLETE DISASTER with that TURBO… If it’s not gonna be TURBOCHARGED and it’s just for testing…it’s still a serious risk and the extra gap helps prevent the rings from pushing outward and well it’s all down hill from there
Nope.
It was fine at that level but any further and we would have.
I would love to see this engine with the stg1 cam and 2 cheap gt35 turbos set to 7lbs of boost through a dual 3 inch exhaust in a 2014 chevy 2500 with a 6L90e transmission.
I have a 2000 blazer exstream id like to put the (#4) set up in. I posted a comment in a older feed. So I'll start again. Do you guys sell the whole thing as a drop in kit ? Or just the parts kit and recommend turbo? Also what year truck or Express van, should I get the 4.3 lv3. It will be very helpful when I call u-pull-it and try and find one or 2 of these things. Thank you!!. For your time.
Hi John, only parts not the whole setup. We can help spec turbos.
2014-19 Sierra and silverado
Or 2018+ Savana and Express vans
