Nice to see a "true" stock engine being used. So many people say stock when in reality they added after market heads, cams, etc. the only thing left that is stock is the block.
Hi...I am situated in Norway and I am building a similar engine for my s10 and would like to thank you for your great videos...they really keep me hyped for our little 4.3 motors...keep up the great work.
Outstanding !! 4.3 has so much to offer and slowly coming out to show its potential. Keep videos coming . I’m confident they can make 400-450 street tune And the right turbo/turbos
Hell yeah buddy that's awesome. I think that's pretty impressive for a stock 4.3 with boost. I can't wait to see what kind of power you will make if and when you build a 4.3 and put that turbo on it lol should be awesome. Love that intake love that rad support btw
I had a 96 gmc sonoma with a weak 175hp rated 4.3. I installed a cam (dont remember the specs) and some head work with bigger intake/exhaust valves. It really woke that engine up i could not believe the difference it made in power. Head flow is the limitig factor, was disappointed your new intake manifold didnt provide better numbers. It was all limited by head airflow.
Love the truck I have a 86 Toyota pickup but the motor is a 94 4.3 with modified 87 heads and Edlebrock intake and carb and hand made headers. It's a fresh build, it's a daily so can't wait to see how it runs
Definitely agree that cam is your limiting factor. If you could keep the same torque for another 1000rpm, it should be closer to 430-450whp, if it doesn't pick up even more from the airflow.
Better too rich than too lean. I am impressed by the intake manifold and the numbers you got. I have an 03 ZR/2 and I'd be happy with 300 WHP. There just isn't much you can by for these engines, performance wise. I'd ove to go aluminum heads and manifold just for the weight savings, but can't find any.
Watched this a few times. Came back. Just watched a 2jz with 6 speed on chassis dyno. Made 420 @19 lbs boost. And you have an auto. So this is a great number considering how "legendary" the 2jz is. Good job
@@manworksgarage wouldn't take very much for a 2jz to hit 500 HP. Not taking nothing away from his build it's very impressive but in no way can you compare a 2jz to a 4.3. The 2jz at 500 HP will last forever but 4.3 stock is a ticking time bomb at 500
@BlackandWhitecustoms I agree with that. I was just comparing 20lb vs 20lbs. Impressed the 4.3 was at same 420 whp. With an auto vs a manual at that. Obviously the 2jz is smaller gonna need more boost but it's got a probably much better head plus vvti.
@BlackandWhitecustoms found a dyno video. 2jz with th400. 499 at wheels 27 psi. Now 27 may blow up the 4.3. Idk. But it's pretty stock. I don't agree the 2jz is so much better than other engines. 500 I a lot more than the original 300 to 326. So it will always take a toll. It's a rather small engine.
I'm from Texas and I have built my 4.3 heavily. In kept the stock camshaft and modded everything else. The camshaft is not the problem. You need to do some porting on both sides and you will see improvement.
when you get some time, maybe make a video on your tunning setup.. ie: ehat tuner, softeware,controller etc you ned/use too tweak' 4.3 gms.. the cost, time to setup, the laerning curve.. and what all intails too buy a tunner, plugs, hookup, start tunning.. and what and were you tune the most with the tuner for boost, other 4.3 related tunning stuff with some basic how too get started.. Ive been around tunning, like ford tweecer, moates quarter horse, etc w/ fords ..but i dont know anything about gm;s.. keep the videos comming love it.. in process od boostin a 03 4.3 5spd in a 1500.. but not sure were what way too go for tunning..
Valve spring upgrade and porting on heads will net you better power for sure! I think with higher lift cam also you will see massive power upgrade! The intake manifold then I turn with more airflow will benefit!!
Rain guards are a must in an s truck. I spray a stock 230k mile 4.3 with a 125 shot no problem lol. . I’ve put probably 30 10lb bottles though it. Dry shot
@@itspickle6664 I blew the 7.5” rear end. The Motor still purs like a kitten. It’ll take that slow 4.3 and light the tires up from a dig lol. I’d spray it the moment my foot hit the floor. I put the nozzle about 4” from the TB.. from what I read the further away kinda softens the hit so to speak. 🤷🏼♂️
Hey what do you use as tuning software? is that the Stock EU? If so I would like to know what you use. I'm going to be doing a Boost Build on my S-10 soon.
Dang man at least a cam would of given more power and is The Best Mod other than Boost lol. Loving this build can't wait. Also better flowing heads will optimize performance with cam and springs.
What would 400 wheel be at the crank? 460-500? That auto is a 4l60e and might be the first thing to go. I'd like to see some porting, cam and springs and a bump up in compression then take it to 600 wheel. If a good crank is available and you forge the bottom you should be ale to run 1000 hp or close to it. But you will need a built turbo 400 and a beefier 3rd member. I would like to see you find the breaking point of the stock short block when you are ready to build the bottom. I think V6's can handle as much as V8's because they are more compact. We used to hit Ford 3.8's with a lot of boost or N20 and they held up to about 800 hp. Where as the 4.6 would break the block at 450 to 500. Love watching this. Keep going.
@@superkillr You weren't paying attention. Only if he is going to build a new forged bottom. Then give it a big bang to see how much the stock short block can handle. I think if he opens the ring gap, it will handle a lot more than we think. Just don't over rev her.
Nice video. I'm guessing the stock V6 Vortec heads is where the most power could be had. There isn't really much out there in the aftermarket for the 4.3L V6 other than Brodix has some heads for it. I'm not sure about cams and intakes. You could do some good porting on those heads and get great gains over the stock flow. I think I read somewhere that someone (Hot Rod?) did some flowbench testing and the gains were significant but compared to aftermarket V8 heads, they we're low. Keep plugging along. Nice to see the 4.3L get some recognition for a power build. Oh, and PowerNation has a 4.3L build going on right now that you might be able to snag some ideas from.
There is a company down there somewhere that builds these 4.3 for some circle racing or somthing like that they do the heads right up. Might be worth talking to them unless he is going to do the machine work himself.... I saved the video I could try to find it and post the link....
I'm a little late to your work. But very inspired. What would it take to get one of those headers sets built for my truck. And one of those intake manifolds very very cool stuff

Nice build. I think you’re just not revving high enough on the stock cam/springs to take advantage of your new intake setup. The marine parts for these engines work quite well on stock blocks up to ~5000 RPM but if you were to take it higher with a bigger cam I believe the new intake would have picked up power. Regardless it’s making good numbers for a bone stock 4.3.
I've been searching which kit to use for a Direct Ignition System conversion, but everything is for V8s. Did you cut the cables it came with the kit to make it a "6 cylinder" kit? All I found was the MSG one. Thanks in advance!
Hi Brandon 👋 👋 👋 👋 just wanted to say your Dino test I thought was very good. Just think your blazing new trials with what your doing with the 4.3 I just wish GM or some of the after market people would of done more. Anyway going now thanks Ray in Idaho
Well lets break this down. 1. Engine in truck check. 2. engine running tires moving on dyno check. 3.3rd gear pull on dyno check. What was the question again?
I've heard from asking when I was thinking of building mine is the cam is a major bottleneck in power I would change that out and take it back to the dyno and see what kinda power you make then keep it up bro
I have a 2021 Silverado with the 4.3L V6 and would love to have a turbo installed on it. Is this a possibility? Not sure about the differences in the generations of 4.3Ls. I just want more power to improve street drivability, not looking to race it. What can you tell me about the possibilities?
Hey man watch Dickey scoggins 4.3 shootout. It’s the newer gen 4.3 and made 600+ hp on a turbo and a stage two came and some race gas you should check it out planning on doing this in my 4.3 next year
@@turbov6 I've see a video where someone did a mild build with a supercharger and where pulling about 600+ hp eventually I want to build something like that or a turbo.
@@turbov6 oh musta been YT then. My motor was non vortec, but made 477awhp on 23psi with a 6266. I raced as high as 28psi and I think I ran the 10.8x passes at about 26. I definitely think the cam is gonna be a huge jump for you. I ran a comp 412 cam and with the springs/retainers revved to 6000. I ran a converter that'd allow me to foot brake to 3400ish and used a msd 2step (6al-2) box and it made a big difference.
Your forcing air in the intake doesn't matter unless it has a huge restriction. The cylinder heads are the worst thing if I could find some good heads for my 4.3 vortec I'd bet that alone could make noticable power gains. Forcing air in isn't really an issue you need to improve the exhaust ports on the heads.
Love it, just got the last bit of parts in for my 4.3 turbo s10 to be done. 👍👍👍 great info, ibseen the 18ish degs at 19psi but how much timing are you running at 8 to 10 psi??
I got a fully stock 4.3 in a 97 jimmy, 270k miles and it’s painful slow I wanna wake it up a bit without spending a ton of money don’t want anything crazy just enough that i don’t feel like a civic 🫡 anyone got any suggestions?
@@turbov6 awesome thx for replying. I'm enjoying the videos; giving me hope that my plans are worth it. I have a 2001 blazer I'd like to twin turbo with an intercooler and an aggressive cam. Really enjoyed your custom intake vid, I'm about to watch it again. Keep it up man 👍.
i have a questioin, from your knowledge, will a vortec 4.3l work ina 93 sonoma with a regular 4.3l with a tbi. i mean as far as computer and stuff like that.
Finally found someone with my same passion for vortec engines....I'm building a 2002 4×4 blazer and need something like that, mine is factory as well!!!! Recommend what should I start with please!!!👌
Is there any way you might could post a video on the setup, as far as turbo type, piping, schematic, piping, intercooler if one, wastegate, etc. I mean, I’d imagine you may have already done this and I just haven’t found it yet, but I’m currently daily-ing a 1995 S10/Blazet, 4DR, 4wd, 4.3 Vortec, and I’ve been scouring the net, you tube, forums, pages, aftermarket websites, etc. And compiling a list of the upgrades, tweaks, build components, performance & visual upgrades/updates/replacements and so on and so forth… I was raised up, riding, driving, customizing, turning wrenches, and straight bleeding Ford Blue… I ADORE the 1998-2008 Rangers, 3.0V6.. I like the 4.0 as well, just partial to the 3.0. This Blazer is my second Chevy, but it’s my first Chevy project/build, and though it’s 4WD, I’m thinking of swapping the front headlights and attached to either an ‘00-‘05 and potentially going with a wide body kit, out to 2wd front end components, doing a 2x2 drop,(upgrading all components I physical touch whilst doing so)/W body kit, possibly doing air suspension later on, upgrades to the top end, ignition, wires, better plugs, upgraded distributor cap & the like, long tube headers for that low end, into an X-pipe resonator delete feeding true dual lines/W HiFlo Catalytic Converters, 2-3/4” exhaust lines into either a Borla or Magnaflo Si/So Performance mufflers on both lines with electronic C/O, Rear drum to disk swap, etc. etc. **ETC** , *Lol* . But, I was wondering if maybe you might have the time, patience, or GaD enough, unlike damn near most anyone else I’ve asked who wouldn’t take the time to correspond on the matter, or allow me to pick their brain while writing shit down and making sure that I don’t screw up along the lines, lol… If not, it’s cool too.. But it never hurts to ask… Nice job BTW.. I look forward to hearing back… THANKS..!
Typical Chevy owner drive to Dyno shop beat the shit outta it with turbo it was never meant for and then have enough faith that your gonna drive it home... Love it
I like V6 engines, but they don't seem to dyno very well.I mean 19 psi boost is 2.29 BAR MAP, right? 401 hp / 2.29 MAP is 175 hå from "The theoretical NA engine". 175 hp 7 262 CID is only 0.76 hp/CID. I think this number speaks for itself so the need for a highflow intanke manifold is very limitied . :)

Solid numbers for a stock 4.3, the tiny stock cam is killing it!
At the 401@19 psi, what did you have the timing set at?
Don’t remember exactly, probably in the high teens
This was @ the wheels. The engine was probably making 460 hp.
@@turbov6 hello do you have a part number on the torque converter you are using
Definitely agree that cam is your limiting factor. If you could keep the same torque for another 1000rpm, it should be closer to 430-450whp, if it doesn't pick up even more from the airflow.

Those things have alot more technology giving them much better boost response as well as torque curve.

you ever going to put a cam in it? there's a company called Delta Camshafts that does regrinds and they have been around since 1977.
Wait did you compare the rods to a gen 3 LS lol…this has sbc rods, the weak link is the rod bolts
I got a fully stock 4.3 in a 97 jimmy, 270k miles and it’s painful slow I wanna wake it up a bit without spending a ton of money don’t want anything crazy just enough that i don’t feel like a civic 🫡 anyone got any suggestions?
You know what cam I can put in a 4.3 08?
Hey love the truck! What radiator support is that?
I made it
I have a s10 with rear mount turbo . Had a few tuning questions for ya if you ever have the chance
Truck sounds good. but it does sound like your torque converter is tight. it revs very linear. jmo
What year is that 4.3?
2003
@@turbov6 awesome thx for replying. I'm enjoying the videos; giving me hope that my plans are worth it. I have a 2001 blazer I'd like to twin turbo with an intercooler and an aggressive cam. Really enjoyed your custom intake vid, I'm about to watch it again. Keep it up man 👍.
Do you know if the rings were gaped and what was the gap
Don't know. I never opened it up
i have a questioin, from your knowledge, will a vortec 4.3l work ina 93 sonoma with a regular 4.3l with a tbi. i mean as far as computer and stuff like that.
In the past I’ve read Crower has a stroker crankshaft I think it cost over 4k do you know anyone with that build and how much a difference it makes
Finally found someone with my same passion for vortec engines....I'm building a 2002 4×4 blazer and need something like that, mine is factory as well!!!! Recommend what should I start with please!!!👌
Can you help me make this intake manifold, I’ve got a built long block ??
Can you point me into the direction of the marine intake for the 4.3

Is there any way you might could post a video on the setup, as far as turbo type, piping, schematic, piping, intercooler if one, wastegate, etc. I mean, I’d imagine you may have already done this and I just haven’t found it yet, but I’m currently daily-ing a 1995 S10/Blazet, 4DR, 4wd, 4.3 Vortec, and I’ve been scouring the net, you tube, forums, pages, aftermarket websites, etc. And compiling a list of the upgrades, tweaks, build components, performance & visual upgrades/updates/replacements and so on and so forth… I was raised up, riding, driving, customizing, turning wrenches, and straight bleeding Ford Blue… I ADORE the 1998-2008 Rangers, 3.0V6.. I like the 4.0 as well, just partial to the 3.0. This Blazer is my second Chevy, but it’s my first Chevy project/build, and though it’s 4WD, I’m thinking of swapping the front headlights and attached to either an ‘00-‘05 and potentially going with a wide body kit, out to 2wd front end components, doing a 2x2 drop,(upgrading all components I physical touch whilst doing so)/W body kit, possibly doing air suspension later on, upgrades to the top end, ignition, wires, better plugs, upgraded distributor cap & the like, long tube headers for that low end, into an X-pipe resonator delete feeding true dual lines/W HiFlo Catalytic Converters, 2-3/4” exhaust lines into either a Borla or Magnaflo Si/So Performance mufflers on both lines with electronic C/O, Rear drum to disk swap, etc. etc. **ETC** , *Lol* . But, I was wondering if maybe you might have the time, patience, or GaD enough, unlike damn near most anyone else I’ve asked who wouldn’t take the time to correspond on the matter, or allow me to pick their brain while writing shit down and making sure that I don’t screw up along the lines, lol… If not, it’s cool too.. But it never hurts to ask… Nice job BTW.. I look forward to hearing back… THANKS..!
Typical Chevy owner drive to Dyno shop beat the shit outta it with turbo it was never meant for and then have enough faith that your gonna drive it home... Love it
What tuning system you using too tune the s10
PCM Hammer & Tuner Pro
I like V6 engines, but they don't seem to dyno very well.I mean 19 psi boost is 2.29 BAR MAP, right? 401 hp / 2.29 MAP is 175 hå from "The theoretical NA engine". 175 hp 7 262 CID is only 0.76 hp/CID. I think this number speaks for itself so the need for a highflow intanke manifold is very limitied . :)
Do have any info on the install of that aluminum core support? Thought about getting one for my '01 ls swap s10 project.
