I have had many 4.3 service vehicles and I beat the hell out of all of them. Max RPM, wide open pulls from every traffic light. Never an issue never burnt oil. Even after 200,000 miles. Great engine…
I've been following this build and I love it! This is almost exactly what I've wanted to do to my 2006 short bed Silverado. It came factory with a 4.3 and there is plenty of room in front of the motor for twin turbos if you are feeling that froggy! If you need something to throw that in let me know, i'd offer up my ride for it, lol!

My 87 one owner 4.3 went 475k miles and i never opened the motor up or had any issues besides a leak from the oil pan gasket. Awesome motor plenty of power super reliable never left me stranded
🤔 You never had to change the transmission, water pump, heater core, ignition module,new oil pump, etc..? After 200K on my 93 4.3, I could feel lower compression. It'd have slightly more power on each 3000mi fresh oil & filter change. Then get weak after the new oil had about 500 miles on it. The truck rotted away before the engine did. I'm guessing had I checked for a weak oil pump & changed it & ran 10W40 in summer instead of 5w30. Once worn, it would have gone to 300K.
@michaelbrinks8089 when I swapped the oil pan I changed the oil pump because it was damaged from the impact. Replaced water pump once, ignition module, and ecu. Along with the alternator a few times. Thats expected wear and tear from daily driving it. transmission I rebuilt it three times. Third time I went with an art carr billet everything in it stage 3 meant for grand nationals with up to 1000HP obviously I wasn't making a quarter of that but I did it for longevity and the 24 inch forged wheels . 10 years later I refreshed the tranny and still going in another MC SS . I always ran 93 and full synthetic Mobil one when it was good oil back then
@michaelbrinks8089 I bypassed by the heater core in the 90s since I'm in miami we don't really have cold winters also I've owned the car since new 0 miles my dad purchased it back then
@@enzos9211 475K is impressive...I think the combination of warm Florida weather & regular oil & filter change using full synthetic was the key....Many people who hear of a vehicle going/lasting 500K miles. Think that means it went 500K with nothing msjor bresking. They don't realize it's engine internals only & it went through several external parts & a few transmissions. I wish I known when I was younger to replace the oil pump around 100K miles. Or when you see the oil psi is lower than norm at idle. The oil pump us still working but lower psi= isn't circulating as good. So the combination of high miles & low psi is wearing it much faster than 50K with strong psi circulation.
He’ll guys, I built a 4.3 many, many years ago for my Buick Grand National. Dual turbos at 73 mm each and I put my alternator and my power steering pump at the 7:30 and 4:30 location underneath my turbos with a big Ron Davis radiator and heat exchanger. Made 552 hp!… but of course, I had a steel crank made and billet rods and forged pistons with a custom (my specs) Crower camshaft. Confirmed 178 mph on route nine going from Middletown to Old Saybrook, Connecticut in nine minutes and 12 seconds but the car got light and scared the hell out of me at that speed! Keep up the good work, and dude, you don’t need that many pens in your shirt pocket! 🧐🤨
I did a similar build back in the day and keep breaking the front end of the crankshaft off right behind 1&2 rod journals never did make it stay together trying different crankshaft from different manufacturers and no one could survive the boost so I gave up on the v6 and went with the small block and had much better success with it.
We found out somewhere between 600-650hp the factory crankshaft is the weak link. We bent ours .004”, just smeared a main bearing which was very lucky it didn’t break. The Bad news, nobody makes an easily available forged steel 4.3 crankshaft and the limited production NASCAR crankshafts are $2800.00+ 😳
@@undertow2142 So many of them available, because the general thought is: Why bother? Anything the 4.3L came in, a V8 practically bolts in. So...people go with the V8. It used to be that people would drop 4.3s into old Jeeps, but even that is kind of run the path and people just go with an LS. There never will be much of a tuning market for the 4.3L, because there isn't enough people interested in supporting it. Sure, there's a few thousand people who really, _really_ like the 4.3L, but a few thousand isn't enough to build a competitive market around.
Its sure a stark contrast to just a few videos ago. Hopefully it was a voluntary choice for health, and not sickness. If it was his choice, then I applaud him!
I could only dream of having this kind of 4.3L in my 1993 Jimmy. I know I could make it happen, but that Holly super sniper...imma keep my eye out for that, the 'spider injectors' aren't the greatest and the plastic clips don't last long, especially with constant heat. Amazing build...and outstanding numbers👀🤤
I've been a fan of Frankie since day one.....But OMG, he's truly become a very important part of this program! His knowledge of turbo installation, as well as welding skills have truly impressed me. So glad to see him working with Pat, he's become an excellent addition to the show!
I’m an LS guy that LOVES the content y’all have doing all kinds of mods to LS motors allowing us to have more knowledge going into builds but seeing boosted v6s is so cool to watch and seeing more would honestly be perfectly fine with me especially since nobody else does it! Love the content as always guys y’all are awesome

This was a great episode! This is like a 4.3 Sy/Ty motor on the cheap. Everyone is starting to navigate to the "Ameribarra" Vortec 4200 inline 6 because completely stock--stock bottom end, stock valve springs, hg, pistons/rods, they've been known to hold 800-850 hp which is amazing but these old 4.3 make terrific budget street motors. If I had an old S10 or S15 Jimmy, I wouldn't be so quick to throw an LS in it. I'd build up a solid bottom end on one of these 4.3, send the heads to get ported, size an appropriate turbo and let it eat. 600 streetable and reliable hp shouldn't be out of the question plus its NOT an LS!!
I have a 1988 S10 Blazer with the stock 2.8 V6. I think this would make a great project for the turbo 4.3 build. Thanks for the video series on the 4.3 Chevy V6. Your fan Mark Boarman.
That 4.3L V6 is probably one of the best motors GM ever made. I had one in a Chevy pick up truck.. It's a big 6 cylinder and it has a lot of power.. GM actually made a few really good 6 cylinder's over the years.. They did a 2.8L that they bumped up to a 3.2L that they used to put in the Z24 Cavilers.. That 4.3L is about as close to an 8 cylinder 5L as you can get. I had a full size 8' bed and loaded that thing up like it was a 3/4 ton Truck even though it was a half Ton truck .. I could tow with it. GM made a yearly solid motor with that 4.3L..
My neighbor and I both bought new 1988 S-10s when the 4.3 first showed up on dealer showrooms. His only lasted 100k miles and his friend rebuilt it and stuck a Holley 4bbl on it. Not for performance, just drivability. My 1988 ran like a champ into the 180K miles and I sold it to a buddy. He drove it for years. Those were great motors in their day. The V8 in my Silverado has been amazing. Fifteen trouble-free years and counting.
The 4.3 v6 was - is bullet proof great engine best v6 I’ve ever used or driven ! I had a 1994 Chevy Astro van work van I started a plumbing business with it lol I pushed it behind it’s limits could not believe what a great little van it was the Astro van was hands down the toughest best mini van of its day ! I use all full size vans now but i was broke when I started my business in like 2008
My buddy had a sweet lowered Astro with a killer paint job A 406 small block in it was WAY better than any V-6 could have been. Only thing we had to do was slide the V-6 motor mounts further forward on the frame, and it was a complete bolt in. The only issue after that was blowing the rear-end several times, and absolutely shredding the rear fiberglass leaf springs until they looked like a grass skirt, or a wooly mammoth.
Wonder if the transfer case and locker in my 03 Astro would like this setup....or a V8 swap for that matter. I promise I won't launch it. Whoah, 525 ft lbs, that's a lot o horsetorques.
@@weaselduke I think it would, if you kept any high traction/high torque equations out of the picture. I had a 1990 Safari AWD, and I replaced the 4.3 V-6 with a stock but completely fresh F.I. 350 V-8, and I beat the livimg shit out of that thing and hurt nothing but U-Joints. Go for it!
Mounting the turbo on a bracket bolted to the head was a slick move, takes stress off exhaust pipes. That makes a custom turbo a lot more do able. I might have to take a look at this setup again!
I built a 1994 4.3 V6 for my 2004 S10 Blazer ZR2. I had splayed 4 bolt mains put in it. Eagle H-Beam rods. Mahle forged 22cc dished pistons. Comp Cams 500/510 lift 270/276 duration cam. Vortec heads ported polished with 2.02/1.60 Manley stainless steel valves. 1.6 aluminum roller rocker arms. ARP head studs and main studs. EFI Connections 1x cam sync, 58x reluctor, and timming cover. Holley HP EFI ECU. Individual LS coil packs. 1992 GMC Syclone intake. Had to 4L60E transmission rebuilt to stage 2. Put a 1995 Oldsmobile Bravada transfer case and right side axle shaft and hoising. A 2002 S10 ZR2 cast iron front differential.
From a Ford guy. GREAT VIDEO! So cool to see this Basically bullet proof engine get monster horsepower and torque! It would be a lot of fun in a Grand national
That's awesome. I'd bet you could throw a set of worked vortec heads on it and a full forged rotating assembly and really get some serious power out of it. I really wanted to build a 4.3 for a long time but iv turned my attention to the l67 3.8s now. My sc Impala SS made me want to build one to put into my S10. Maybe someday I'll pull it out of the weeds and into the shop...
Cool viddy! And for once I can relate.., I have a 4.3 in my 2001 GMC Sonoma daily driver that I was lucky enough to buy (first ever financed, paid off early..,)in 2017. I have 99635 miles on the odo, & have replaced the fuel regulator/spider, starter & currently chasing down a service engine code P0401( secondary air system) that appears to require replacement of the check valves to clear the code & pass smog inspection.., having said all that the power has always been more than I needed & with today’s gas prices fuel economy is still holding up @ 15-18 city(whew..!). I love my truck. I am not going to beg, whine or blow smoke, just keep doing whatcha doing, I will continue to watch & enjoy!! Hell ya’ brother!
A well machined 4.3 is a great engine. Had a 94' and it was one of the best engines I ever owned. Always wanted to drive a Cyclone. When they drilled to far into the water jacket to add the supercharger is the only problem I remember with those.
@@bobbymartinez3030 I did say with a tuner . I had a 6.5 . It was my first diesel . It was a real dog. Great on fuel though . I now have a compound cummins and I also have forged turbocharged 383 sbc. I would never use my turbocharged small block to tow a 20k load . Point of my statement was its not what the peak tq is but also where in the rpm band it is . Every job has a a tool best suited.
Yes Sirs and Ladies! These little overlooked V6 4.3Ls are the most underrated of the basically SBC's with the weight reduction of the V8 and the almost identical internals to the SBC. These engines have a ton of potential especially if someone decides to actually make a good set of aluminum heads for the 90° V6 generation engines. It's bad enough that you have no real selections to intake manifolds or headers for them! But this is why they don't have a big following unfortunately. Why bother building a turbo engine that's only 3.8 liters when you could have much more cubes to pump through the turbo! This means much more torque and top end HP. It's a shame that these aftermarket companies don't make much for them besides stock replacement parts? 😕 Imagine one with a decent set of aluminum heads for flow and heat reduction plus weight reduction! Added with a Victor Jr style intake and a good set of Hooker super comp stepped headers, just this combination is going to add an additional 80-120Hp naturally aspirated no less. If you add the turbo and take advantage of the better flowing top end, it's basically almost a 800-900Hp engine that can be built reliably for the street and strip. The crankshaft is the next weakest link and if they made a short 350 or 400 crankshaft you could even stroke them out using the 3.75" 400 style crankshaft and gain a ton more cubes by doing so. But I'm definitely dreaming, because now that the LS generation has taken hold, the love and interest of the aftermarket companies are onto the LS parts and aren't going to waste their money and time going backwards in technology to build older parts for a engine GM stopped making almost 20 years ago. The fact is they were absolute animals from the factory in the Typhoons with the turbocharger and even the NA engines like I had in my S-10 blazer and Astro van were killer powerful torque monsters for a V6 of their generation. Nice to see they are getting some recognition! Be a great project to put in a Buick Regal If you're building a GN replica or tribute car! It be faster than the original GNX and a lot cheaper than building a Buick engine for something like that.......
4.3 L isn’t that tiny :P here on the european continent we have 3.0 diesels with more hp and torque. Look up what the om606 and the m57 from mercedes and BMW can do :D
@@mplewp Given the same deck height, the pushrod engine will have more displacement than a DOHC, albeit with a slightly longer block. The 4.3L pushrod engine is hardly "bigger" than a ~3.0 L DOHC, rather it has more "empty space" inside the block corresponding to the higher displacement. Another myth is that 4 valves per cylinder allows more airflow, but a hemi head with 2 valves is the highest possible flow.
Pent roof 4-valves are geometrically equivalent to a hemi as far as valve areas are concerned, but they can use more of the bore area. So they do indeed flow better. Bigger difference however: the curtain area increases a lot faster than a 2 valve head. This allows 4-valve heads to flow better with a milder cam, which is ideal for drivability and emissions in a street car.
@@nerd1000ify I'm contending it's not physically possible to fit 4 round holes with more area than 2 round holes. If you're right, the NHRA would like to know.
Lol great content guys. Back in the early 2000s I wanted to do this in a ASTRO but I got married and the kids came lol. Now they are grown I can start playing around again.
This needs to be taken to the next level with 96+ vortec heads and add a 2nd turbo!! I’m building a 275 cube V6 with twin 58/55 turbos, Brodix aluminum heads and a GM crossram intake modified for EFI and dual DWB TB’s. Should be good for 2.5+HP per cube.
My 93 Typhoon is my dream car for a reason. I love it. With an MSD, decent exhaust and a few tweaks it makes 490 street legal horses. The ricers here in Caliornia absolutely hate mè.
I had a 92 Chevy c1500 long bed that I bought new w the 4.3. Traded it in 2000 and it had 100k miles plus and ran great. That engine in that truck would be awesome. Also had an 89 s10 w the 4.3 and nobody w stock stuff could beat it
The 4.3 is a fantastic engine. Some years had the awful hard plastic intake gaskets that would disintegrate and create large leaks. If you were lucky they’d leak externally. If you were unlucky they’d leak into the valley.
@@uglymechanics6599 I ran 93 and 94. Sunoco here used to have 94 then. I made 470whp but I had other things done too. It was all on stock rods, pistons, crank etc.. From a L35.

I have an 05’ Reg. Cab SWB 2wd 4.3L OE rebuild nightmare. I’ve replaced the Engine & Trans among $9k worth of other stuff. I did all the work myself. I want to get this truck into a much more throttle responsive 400hp-450+hp romper with a strong solid Hyd roller cam, a strong turbo, headers & exhaust, new worthy intake & most importantly a NEW fuel management system that actually works for this truck. The spider injection system sucks to say the least. I would & could really use some help from you guys. I’m $17k plus deep in a $4k truck (in perfect condition) and I’m so tired of failing with this project. And so is my wife. I started this driveway project in the summer of 2019 after it completely failed me one day trying to drive to work as it was my basic daily driver. Long story short, after checking everything I could without tearing down, I got nowhere. I ended up replacing everything single thing available. Some stock OEM parts I just can’t find. It fires up and idles fine from a cold start. It gets to about mid half temp then struggles & dies. I need some serious help. I’ve already bought a new truck. Now this is a special project truck & so will be the original engine & Trans which are sitting in the back/bed of this truck.
I had a 1999 S10 ZR2 5speed pickup for a number of years. Great truck other than not much power. I always thought a single turbo would be a good thing for the 4.3 in that platform but no kits and I did not want to try and build my own. I like what you did, great series.
This is why I love boost and particularly turbos. When boost comes on, you get instant torque gains and it can carry throughout the rev range. I know this is not an exhaustive lesson on turbos, but the audience might want to know about wastegate prioritization for controlling boost. Not critical in this application, but imperative in keeping an engine from over boosting. I've also never seen anyone put the O2 sensor before the turbo. I don't think it would change much other than giving the sensor some positive pressure to fight against. Franky said he likes V6s more now because of this. The Ford Ecoboost is an OEM example of this working, but there are several OEMs that have done this. Straight 6s are bit more common, but 6 cylinders tend to be more harmonically balanced and smoother running. Turbos make a great match with that. Now to get you to like 4 cylinders more :-)
This is probaly in the top 10 of chevy motors. It just goes and goes and its just a short block V8 with 2 cylinders lopped off, so easy to work on - great motor.
I definitely love the six-cylinder build. I want to see a six cylinder build like you’ve not done before. Maybe the 3100/3400/3800 Chevy 60° V6 is especially since I’ve always heard that for the most part they’re impossible to make power with. So, I would like to see you guys make power with them, especially with the scarcity of aftermarket parts, potentially being a problem. And with the 3800 coming from the factory with a supercharger, sometimes that could make your choices more interesting.
Just remember the cyclone and typhoon had turbo 4.3s stock from the factory. Ive seen many of these great engines run low 1/4 mile times.as a Gn owner i prefer a v6 turbo over a v8 anyday
One BAD Mama Jama! I love this! Great and wonderful work Pat and Frankie! Keep 'em comin'! A real tribute to the Turbo Buicks of the 80's and the GMC Syclone and Typhoon of the 90's! : )
I have a 1990 ASC McLaren Turbo 3.1 Grand Prix with 175K miles on it. I would LOVE to see you guys do a GM60 degree V6 build. They used the 60degree engine in millions of cars from the early 80s to the 2000s including Camaros, Fieros, Firebirds, Oldsmobiles, Chevys, Buicks and of course, my Grand Prix.
This video answered my question of if the Holley Sniper EFI would work on a V6. Also a centrifugal supercharger would've been easier to work with than custom turbo set up, yes it's a little pricey but less work
Lean it out on the midrange and put in an oil cooler and it would be fine at 10 psi without sacrificing reliability. I dont know what cam is in there but I think you may be blowing out some boost on overlap at about 4700 rpm. With those torque numbers I actually think it would be better supercharging it for a street car.
I'd put a smaller turbo that spooled at lower RPM so the torque would come in lower. For a street truck (what most of these 4.3L came in) it would be more fun than peak top end power. I have a 4.3L in one of my trucks. I put in a 2400 RPM converter so it will stall around the peak N/A torque and it seemed to wake it up a bit. I'd love to have 350 ft lbs at 2400-2600 RPM because it would make the truck feel a lot more powerful and pull better. I could care less about running the engine to 6000+ RPM because 95% of the time it's driven under 3000 RPM. Even a roots blower would be more fun since those make torque down low.
seeing this makes me smile. I’ve heard a lot of criticism about how bad they are. i do own a 91 s10 blazer that has a little 4.3 in it and i love it. it’s been the best little thing i’ve ever bought next to my 83 camaro. Ya’ll did amazing on the work you did on it.!!
You guys would love the 3800 s2 motors. It's a v6 like this block but only slightly smaller but gives a lot of power and tq. when turboed. There's millions of these motors everywhere in cars it's almost impossible to not see 1 or 5 on your way to work or around town. Lots of ppl build up their motors and can get around 500hp or more if built to the max. Most put a super charger on theirs and call it good but that's the v6s down fall it doesn't have enough space to charge the air unlike a turbo. Best of all its almost impossible to ruin these motors. Several of these motors can see upwards of 500k miles or more. So it's built tough even the supercharged motors can see 500k miles the trannies on the other hand don't see more than 100k lol.
Are used to have a 80 Malibu wagon with a 3.8 L my plans back then were to pull it out and put a 350 in there to get more power. I never thought about turbo charging it now you’re giving me that itch to get another one and turbo it.😮
Amazing talent and knowledge from a couple of separate generations with different points of view!!! Great respectful points of view that create AMAZING RESULTS!!! Keep it coming guys! We are all ears👂👂👂‼️
Absolutely fantastic project/ build. It’s nice to see something other than V8 build. This build is very motivating and the cost of a used 4.3l are build friendly. I would love to see a 2.5l build that also came in the S-10s.
Keep in mind the reason some of these old engines would last so long is because in stocks trim they didn't make enough power to hurt it. Think ford 300 is. But I'm just some guy in the internet

Dual turbos at 73 mm each and I put my alternator and my power steering pump at the 7:30 and 4:30 location underneath my turbos with a big Ron Davis radiator and heat exchanger. Made 552 hp!… but of course, I had a steel crank made and billet rods and forged pistons with a custom (my specs) Crower camshaft. Confirmed 178 mph on route nine going from Middletown to Old Saybrook, Connecticut in nine minutes and 12 seconds but the car got light and scared the hell out of me at that speed! Keep up the good work, and dude, you don’t need that many pens in your shirt pocket! 🧐🤨
I did a similar build back in the day and keep breaking the front end of the crankshaft off right behind 1&2 rod journals never did make it stay together trying different crankshaft from different manufacturers and no one could survive the boost so I gave up on the v6 and went with the small block and had much better success with it.
Rt 2?
We found out somewhere between 600-650hp the factory crankshaft is the weak link. We bent ours .004”, just smeared a main bearing which was very lucky it didn’t break.
The Bad news, nobody makes an easily available forged steel 4.3 crankshaft and the limited production NASCAR crankshafts are $2800.00+ 😳
There really should be a better tuning market for these 4.3s. So many of them out there.
2800 for a forged crank is cheap !!
Actually there is a 3.6 stroke forged evenfire crank available if you know who to talk to. $2K shipped.
@@undertow2142 So many of them available, because the general thought is:
Why bother?
Anything the 4.3L came in, a V8 practically bolts in. So...people go with the V8.
It used to be that people would drop 4.3s into old Jeeps, but even that is kind of run the path and people just go with an LS.
There never will be much of a tuning market for the 4.3L, because there isn't enough people interested in supporting it. Sure, there's a few thousand people who really, _really_ like the 4.3L, but a few thousand isn't enough to build a competitive market around.
@@supersevenn no it’s not😂
Please put it in a first gen S10! I would love to build a similar setup out of the stock 4.3 that is in my truck.
Nah that sucker should be in a boat.
The 4.3 Vortec is such a great engine ❤

Frankies come a long way in a short time he’s been with you folks and us. Good job Frankie I’ve already learned stuff from you :-)
You even had me on the edge of my seat in Australia...lol nice work guys, that was fun.
I could only dream of having this kind of 4.3L in my 1993 Jimmy. I know I could make it happen, but that Holly super sniper...imma keep my eye out for that, the 'spider injectors' aren't the greatest and the plastic clips don't last long, especially with constant heat. Amazing build...and outstanding numbers👀🤤
There's always the Mercruiser 4.3L marine intake manifold that uses rail injection too
I've been a fan of Frankie since day one.....But OMG, he's truly become a very important part of this program! His knowledge of turbo installation, as well as welding skills have truly impressed me. So glad to see him working with Pat, he's become an excellent addition to the show!
262 HP. Nice! 1HP per cubic inch. Not often you see an older iron V6 do that. These originally made 190'ish HP.
My '65 Corvair 164 C.I. turbo makes 180hp factory.
Not quite... It's a 266 now.
You guys really had fun with this one! Cool build, and cool content!
I’m an LS guy that LOVES the content y’all have doing all kinds of mods to LS motors allowing us to have more knowledge going into builds but seeing boosted v6s is so cool to watch and seeing more would honestly be perfectly fine with me especially since nobody else does it!
Love the content as always guys y’all are awesome

so glad you guys finished this project off with boost! been waiting for this one.
WOW ! Outstanding build! You guys just changed my opinion of that V6! Thank you for a fantastic video!!
Thanks for doing this production! I always wondered what a 4.3 could do if built right with a power adder. I very much enjoyed it!!!
This was a great episode! This is like a 4.3 Sy/Ty motor on the cheap. Everyone is starting to navigate to the "Ameribarra" Vortec 4200 inline 6 because completely stock--stock bottom end, stock valve springs, hg, pistons/rods, they've been known to hold 800-850 hp which is amazing but these old 4.3 make terrific budget street motors. If I had an old S10 or S15 Jimmy, I wouldn't be so quick to throw an LS in it. I'd build up a solid bottom end on one of these 4.3, send the heads to get ported, size an appropriate turbo and let it eat. 600 streetable and reliable hp shouldn't be out of the question plus its NOT an LS!!
I have a 1988 S10 Blazer with the stock 2.8 V6. I think this would make a great project for the turbo 4.3 build. Thanks for the video series on the 4.3 Chevy V6. Your fan Mark Boarman.
That 4.3L V6 is probably one of the best motors GM ever made. I had one in a Chevy pick up truck.. It's a big 6 cylinder and it has a lot of power.. GM actually made a few really good 6 cylinder's over the years.. They did a 2.8L that they bumped up to a 3.2L that they used to put in the Z24 Cavilers.. That 4.3L is about as close to an 8 cylinder 5L as you can get. I had a full size 8' bed and loaded that thing up like it was a 3/4 ton Truck even though it was a half Ton truck .. I could tow with it. GM made a yearly solid motor with that 4.3L..
Their N/A dyno numbers were almost exactly what a stock 5.3 vortec truck motor from 2005 makes. Pretty impressive
That would be great in my 98 gmc Sonoma. It's a 4wd I want to convert into awd and make a gen 2 Syclone. Maybe one day... nice build 😉👍🏼

My neighbor and I both bought new 1988 S-10s when the 4.3 first showed up on dealer showrooms. His only lasted 100k miles and his friend rebuilt it and stuck a Holley 4bbl on it. Not for performance, just drivability. My 1988 ran like a champ into the 180K miles and I sold it to a buddy. He drove it for years. Those were great motors in their day. The V8 in my Silverado has been amazing. Fifteen trouble-free years and counting.
The 4.3 v6 was - is bullet proof great engine best v6 I’ve ever used or driven ! I had a 1994 Chevy Astro van work van I started a plumbing business with it lol I pushed it behind it’s limits could not believe what a great little van it was the Astro van was hands down the toughest best mini van of its day ! I use all full size vans now but i was broke when I started my business in like 2008
That motor is definitely making some good power
Neat to see my beloved 4.3l hopped up and tested. Thanks
That engine would go great in a Chevy Astro or GMC Safari. It would be a beast.
I had 2 Astros when I was in high school one had the 4.3l high output engine. I love a good van build.
My buddy had a sweet lowered Astro with a killer paint job
A 406 small block in it was WAY better than any V-6 could have been. Only thing we had to do was slide the V-6 motor mounts further forward on the frame, and it was a complete bolt in. The only issue after that was blowing the rear-end several times, and absolutely shredding the rear fiberglass leaf springs until they looked like a grass skirt, or a wooly mammoth.
Wonder if the transfer case and locker in my 03 Astro would like this setup....or a V8 swap for that matter. I promise I won't launch it. Whoah, 525 ft lbs, that's a lot o horsetorques.
@@weaselduke I think it would, if you kept any high traction/high torque equations out of the picture.
I had a 1990 Safari AWD, and I replaced the 4.3 V-6 with a stock but completely fresh F.I. 350 V-8, and I beat the livimg shit out of that thing and hurt nothing but U-Joints.
Go for it!
Mounting the turbo on a bracket bolted to the head was a slick move, takes stress off exhaust pipes. That makes a custom turbo a lot more do able. I might have to take a look at this setup again!
Pat has really grown on me. Love that they are showing more of his silliness lately. Still miss Mike Galley tho 🍻
I built a 1994 4.3 V6 for my 2004 S10 Blazer ZR2. I had splayed 4 bolt mains put in it. Eagle H-Beam rods. Mahle forged 22cc dished pistons. Comp Cams 500/510 lift 270/276 duration cam.

A well machined 4.3 is a great engine. Had a 94' and it was one of the best engines I ever owned. Always wanted to drive a Cyclone. When they drilled to far into the water jacket to add the supercharger is the only problem I remember with those.
Dang! That little six cylinder makes as much torque as my turbo diesel V8.
If you think that's good, check out the new lt based direct injected 4.3

Yes Sirs and Ladies! These little overlooked V6 4.3Ls are the most underrated of the basically SBC's with the weight reduction of the V8 and the almost identical internals to the SBC. These engines have a ton of potential especially if someone decides to actually make a good set of aluminum heads for the 90° V6 generation engines. It's bad enough that you have no real selections to intake manifolds or headers for them! But this is why they don't have a big following unfortunately. Why bother building a turbo engine that's only 3.8 liters when you could have much more cubes to pump through the turbo! This means much more torque and top end HP. It's a shame that these aftermarket companies don't make much for them besides stock replacement parts? 😕 Imagine one with a decent set of aluminum heads for flow and heat reduction plus weight reduction! Added with a Victor Jr style intake and a good set of Hooker super comp stepped headers, just this combination is going to add an additional 80-120Hp naturally aspirated no less. If you add the turbo and take advantage of the better flowing top end, it's basically almost a 800-900Hp engine that can be built reliably for the street and strip. The crankshaft is the next weakest link and if they made a short 350 or 400 crankshaft you could even stroke them out using the 3.75" 400 style crankshaft and gain a ton more cubes by doing so. But I'm definitely dreaming, because now that the LS generation has taken hold, the love and interest of the aftermarket companies are onto the LS parts and aren't going to waste their money and time going backwards in technology to build older parts for a engine GM stopped making almost 20 years ago. The fact is they were absolute animals from the factory in the Typhoons with the turbocharger and even the NA engines like I had in my S-10 blazer and Astro van were killer powerful torque monsters for a V6 of their generation. Nice to see they are getting some recognition! Be a great project to put in a Buick Regal If you're building a GN replica or tribute car! It be faster than the original GNX and a lot cheaper than building a Buick engine for something like that.......
Still looking for ya'll to put an Iron Duke together.
Just sold a Tacoma built on your guys show.

Great build guys.
Insane amount of power from that tiny engine 😳.
4.3 L isn’t that tiny :P here on the european continent we have 3.0 diesels with more hp and torque. Look up what the om606 and the m57 from mercedes and BMW can do :D
@@mplewp can’t compare torque levels from a gasser to a diesel
@@mplewp Given the same deck height, the pushrod engine will have more displacement than a DOHC, albeit with a slightly longer block. The 4.3L pushrod engine is hardly "bigger" than a ~3.0 L DOHC, rather it has more "empty space" inside the block corresponding to the higher displacement. Another myth is that 4 valves per cylinder allows more airflow, but a hemi head with 2 valves is the highest possible flow.
Pent roof 4-valves are geometrically equivalent to a hemi as far as valve areas are concerned, but they can use more of the bore area. So they do indeed flow better. Bigger difference however: the curtain area increases a lot faster than a 2 valve head. This allows 4-valve heads to flow better with a milder cam, which is ideal for drivability and emissions in a street car.

Wonder what 96+ vortec heads and edelbrock vortec swap intake would have made na on that.
The 4.3 is a fantastic engine. Some years had the awful hard plastic intake gaskets that would disintegrate and create large leaks. If you were lucky they’d leak externally. If you were unlucky they’d leak into the valley.
I'm sure the crank shaft appreciated yall stopping at 13.8 psi
It will never see 13 on the road tho

Long story short, after checking everything I could without tearing down, I got nowhere. I ended up replacing everything single thing available. Some stock OEM parts I just can’t find. It fires up and idles fine from a cold start. It gets to about mid half temp then struggles & dies. I need some serious help. I’ve already bought a new truck. Now this is a special project truck & so will be the original engine & Trans which are sitting in the back/bed of this truck.
Wonder what a set of Brodix heads and E85 would do with that combo...
I know Holdener loves his E85 for boosted applications
I once had a 4.3 in a Suzuki Samurai… I always wanted to boost it. Thanks for showing your project.
Haha Big block Samurai!! Awesome.
Did you use a tbi or vortec motor?
Basically same motor. Heads a bit different. Think its TBI
I had a 1999 S10 ZR2 5speed pickup for a number of years. Great truck other than not much power. I always thought a single turbo would be a good thing for the 4.3 in that platform but no kits and I did not want to try and build my own. I like what you did, great series.
This is why I love boost and particularly turbos. When boost comes on, you get instant torque gains and it can carry throughout the rev range. I know this is not an exhaustive lesson on turbos, but the audience might want to know about wastegate prioritization for controlling boost. Not critical in this application, but imperative in keeping an engine from over boosting. I've also never seen anyone put the O2 sensor before the turbo. I don't think it would change much other than giving the sensor some positive pressure to fight against.
Franky said he likes V6s more now because of this. The Ford Ecoboost is an OEM example of this working, but there are several OEMs that have done this. Straight 6s are bit more common, but 6 cylinders tend to be more harmonically balanced and smoother running. Turbos make a great match with that. Now to get you to like 4 cylinders more :-)
This is probaly in the top 10 of chevy motors. It just goes and goes and its just a short block V8 with 2 cylinders lopped off, so easy to work on - great motor.
The 300 made 122lbs tq per litre and so did the 4.3
The 4 3 just required a pinch more boost
Hell yeah! I've always wanted to see this buildup in a project.
I’d love to see this in something strange, like an old skylark convertible 😂
AWD Astro 👌
I definitely love the six-cylinder build. I want to see a six cylinder build like you’ve not done before. Maybe the 3100/3400/3800 Chevy 60° V6 is especially since I’ve always heard that for the most part they’re impossible to make power with. So, I would like to see you guys make power with them, especially with the scarcity of aftermarket parts, potentially being a problem. And with the 3800 coming from the factory with a supercharger, sometimes that could make your choices more interesting.

I have a 1990 ASC McLaren Turbo 3.1 Grand Prix with 175K miles on it. I would LOVE to see you guys do a GM60 degree V6 build. They used the 60degree engine in millions of cars from the early 80s to the 2000s including Camaros, Fieros, Firebirds, Oldsmobiles, Chevys, Buicks and of course, my Grand Prix.
This video answered my question of if the Holley Sniper EFI would work on a V6. Also a centrifugal supercharger would've been easier to work with than custom turbo set up, yes it's a little pricey but less work
Lean it out on the midrange and put in an oil cooler and it would be fine at 10 psi without sacrificing reliability. I dont know what cam is in there but I think you may be blowing out some boost on overlap at about 4700 rpm. With those torque numbers I actually think it would be better supercharging it for a street car.
I'd put a smaller turbo that spooled at lower RPM so the torque would come in lower. For a street truck (what most of these 4.3L came in) it would be more fun than peak top end power. I have a 4.3L in one of my trucks. I put in a 2400 RPM converter so it will stall around the peak N/A torque and it seemed to wake it up a bit. I'd love to have 350 ft lbs at 2400-2600 RPM because it would make the truck feel a lot more powerful and pull better. I could care less about running the engine to 6000+ RPM because 95% of the time it's driven under 3000 RPM. Even a roots blower would be more fun since those make torque down low.
seeing this makes me smile. I’ve heard a lot of criticism about how bad they are. i do own a 91 s10 blazer that has a little 4.3 in it and i love it. it’s been the best little thing i’ve ever bought next to my 83 camaro. Ya’ll did amazing on the work you did on it.!!

THANK YOU SO MUCH. A TOTALLY AWSOME BUILD!!!! I LOVE EVERYTHING!!!!
You guys would love the 3800 s2 motors. It's a v6 like this block but only slightly smaller but gives a lot of power and tq. when turboed. There's millions of these motors everywhere in cars it's almost impossible to not see 1 or 5 on your way to work or around town. Lots of ppl build up their motors and can get around 500hp or more if built to the max. Most put a super charger on theirs and call it good but that's the v6s down fall it doesn't have enough space to charge the air unlike a turbo. Best of all its almost impossible to ruin these motors. Several of these motors can see upwards of 500k miles or more. So it's built tough even the supercharged motors can see 500k miles the trannies on the other hand don't see more than 100k lol.

5k on machining : ) if your gonna go all out on it like my crazy ass
Keep in mind the reason some of these old engines would last so long is because in stocks trim they didn't make enough power to hurt it. Think ford 300 is. But I'm just some guy in the internet
