I know this video is old but I cant believe the amount of hate going on in the comments. You guys that are bashing the dude started somewhere. Hotrodding in general did not start out with Tig torch and mandrel bent pipe. It all started with an idea and someone willing to try. If people actually listened to you negative Nancy's we would still be walking around hunched over, dragging woman by the hair.
Nothin like a guy playing SJW in the comments by generalizing everyone about being negative, while talking shit about them talking shit or not liking the video lmao #LogicFail
I say good job doing it the way you are. Dude said hes only using a 110 welder, so its not going to flow like a 220 or a tig. Saving money is the point, and if it works who gives a shit what it looks like especially under header wrap. At least he has the nuts to get out in the shop and cut some shit up. Cast steel is perfectly fine, you wouldn't even attempt this with cast iron. I'm not saying its how i would do it but if it works, hell yea
So happy I found out about the flipping stock manifolds trick to make turbo manifolds.. doing a twin turbo setup on my 4.8L in a silverado and could only find manifolds for about 1k for a pair, so I’m super excited about saving that money !!
Awsome! This goes to show, you dont have to use 900 bucks on new headers just to get the turbos mounted. This Is as simple as it gets, and it works. Thanks for the video Justin.
its all about doing it on a budget. they may not last as long as a full stainless tig welded set up but this costs nothing or next to nothing and gives someone an alternative to spending a big buck up front. could always weld up a proper one if you wanted to after the fact. good video and cool idea to save money. and yes i am a machinist and understand the metallurgy of cast and welding weakens the manifold.
Looks like could maybe flatten out the radius the inside of the tubing to gain a little more room for the plug wires . but good job for a DIY manifold .
I mean, for a quick and dirty setup, I guess this works - sort of a "REALLY on a budget, trying to salvage what I can, and make it work". I think ideally, you'd want to just buy a bunch of proper exhaust grade mandrel bent piping, and have it custom cut, and welded. All the same material, no franken builds, better flow... HOWEVER, all the comments on the weld quality aside, this is great for the backyard/junkyard part builder. Kinda cool!
While not the most aesthetically pleasing - I think your ingenuity is AWESOME! - Get a better welder and some better metal cutting tools - you'd be A+! Outside of that small critique - Your effort and willingness to share is great! Keep it up!
all the haters are obviously the fuckwits that paid 600 for a manifold an got someone to put it on for them then go telling prople how they built their setup . good work man it doesnt have to look pretty to make power i have made plenty of manifolds like this and had them last years without fault
Or legitimate fabricators who see this crap and knows that everything here is wrong. Does it work? Sure. But garbage is still garbage. Fitting is poor, welds are poor, materials used are poor.
I see some of the comments about cleanliness but, I know nothing about welding! I went to harbor freigt to get a stick welder but they were out so, I bought their 110 wire feed 90amp & my results are horrible! mind u,I did replace the wire with wire purchaced from lowes. I need clean metal to practice on!!!!
might be an idea to sell coil relocation kits so they mound under the manifolds friend of mine allmost burned down his truck using headerwrap , he had an oilleak and the wrap absorbed it , when the exhaust whent beyond the flashpoint of the oil it caught fire
The welding needs addressing, have you crack tested it yet? If it's cast it needs a good pre-heat first prior to welding as the expansion differential will crack those welds given time. Excellent advice on the hacks, I'm building a stainless header for my Evo 8 at the moment, many headaches yet to come I fear ;)
This is fucking awesome lmao. I want to do a top mount for my 03 silverado. Suppose I could do this without splitting the manifold and just cutting the flange off and adding a 45 or so with the T3/T4 flange on top of the pipe?
don't see why it wouldn't work. just make sure you are feeding the turbo wiith both sides of the engine and youll be alright. or a twin turbo system. you can look at how i did mine on my channel
your cool bro, thanks for taking the time to make your vids. how to you go about making sure there isn't any spatter on the inside that may come loose and trash the turbo. or has that not really been an issue
i worry about this too. but i tried to get inside as good as i could and clean out any wire that went inside and stuff. check out a video i just uploaded i show a little bit of the manifold i built in that video
Is the pipe just standard exhaust tubing you can get from the auto parts store? Literally saw the video and began cutting my stock manifold. I have 2.5” exhaust pipe just wanna make sure I can use it
Do you know exactly what truck eng the manifold you used in the vid came off. I want to try this and want to make sure I get the cast steel and not cast iron manifolds.
I love when people do this lmao At this point you might as well make a full custom manifold. The entire structural integrity of the cast manifold you just ruined by cutting the spine and adding thin wall tubing. Again might as well make the entire thing thin wall. Just makes it look better and not back yard cheap mechanic.
Just inSane. Setting aside the aesthetics and possible cracking issues previously mentioned, this system will not perform as well as a mandrel bent or weld-el setup that is well designed and built. Granted this is gonna be drastically cheaper, you get what you pay for...
Hey man from what I've heard most manifolds are cast iron. how is the best way to tell what your working with? I've got a 99 silverado 4.8 and not sure at all what there made out of.
they are most likely cast steel. don't know who told you they were mostly cast iron. yes maybe on other angines like the older sbc engines (305, 350) but the newer ls engines have cast steel manifolds. you should be fine doing this and if not you can pick up one of these from practically everywhere for about 30$
+snail5341 equal length tubing can be a bonus but not %100 necessary. Many companies and OEM brands will use a log style or cast manifold with great success at the low to mid range power levels. You will however usually see equal length headers on higher power turbo builds for even exhaust pulses and scavenging which will lead to a more smooth turbo spool. Likewise they will also be used on more expensive systems when you want more efficiency. Not saying it is a high end upgrade but in the Subaru market, equal length headers are some of that communities first parts swapped on turboed boxer engines.
the cams on a turbo however don't overlap like they do on a big NA cam so its not really scavenging. still equal length tubing is nice and would provide evenly distributed backpressure and even less backpressure
It is weldable just difficult if not heated and when trying to weld cast to mild steel you end up with either cracks or Easley ending up with fighting impurities while welding it
Would you recommend painting the manifold with hi temp paint before wraping them ? I have herd the manifold could rust pretty bad from the heat cycle ,any experience with that ?
+Justin Sane ok thanks. What type of metal is the pipe you are welding to the manifold and did you order a kit with all the different bends and diameters ? Great vid btw loved how it looked when finished. Liked and subscribed.

and the smile you get when it works is cool

Thanks for showing how you did your setup. The idea is priceless.
Looks good. If you blend it, shoot some high temp paint, it'll look bad ass. Either way, I did something similar.
couldnt you use a 6.5 diesel manifold set and work around the clearance issues ? if i recall correct they should fit
Great video, thanks for taking the time to show all of that. Tom
Its a very good video. It gives you a lot of information on how to. If ur on a budget, this is the way to go. Way to go.

ben cowell there junk just go buy them for 150 3inch at yearwood
Great video!!! I never even thought to do this after pricing that specific manifold. I have a Lincoln Pro Mig 140, I might try this
looks good I have a sloppy 7875 kit and looking at making my own hot side
I see some of the comments about cleanliness but, I know nothing about welding! I went to harbor freigt to get a stick welder but they were out so, I bought their 110 wire feed 90amp & my results are horrible! mind u,I did replace the wire with wire purchaced from lowes.

how long will this steel last with the turbo heat
might be an idea to sell coil relocation kits so they mound under the manifolds
friend of mine allmost burned down his truck using headerwrap , he had an oilleak and the wrap absorbed it , when the exhaust whent beyond the flashpoint of the oil it caught fire
As long as your expectations are really really low, I’d say it’s a win!
im curious on how its holding up with just that exhaust tubing.
The welding needs addressing, have you crack tested it yet? If it's cast it needs a good pre-heat first prior to welding as the expansion differential will crack those welds given time. Excellent advice on the hacks, I'm building a stainless header for my Evo 8 at the moment, many headaches yet to come I fear ;)
I wanna see how you fill the gaps between the turbo flange and outlet from the manifold
shes aint pretty but she will work for a fraction of the price thanks for making the video
depending on cost,i would like to see a manifold for a 03 focus zetec 2.0 dohc vin 3 $$$?
Nice work, very resourceful. Where do you get your bends?
You need a workbench.
love seeing stuff like this so cool
Fuck cut to the chase.... "but what I'm going to show you today". Jeezzhh
So how much is your turbo LS kit for a 2011 4.8L and I'm talking the simplest and easiest one you have. Lol
This is fucking awesome lmao. I want to do a top mount for my 03 silverado. Suppose I could do this without splitting the manifold and just cutting the flange off and adding a 45 or so with the T3/T4 flange on top of the pipe?
don't see why it wouldn't work. just make sure you are feeding the turbo wiith both sides of the engine and youll be alright. or a twin turbo system. you can look at how i did mine on my channel
what did you use to cut the manifold?
How long did this hold up before the welds cracked?
Justin. ...you still got that Awd civic bro.......
What year and model of the MANIFOLD on the right you already cut, angular the v band? Smaller one
your cool bro, thanks for taking the time to make your vids. how to you go about making sure there isn't any spatter on the inside that may come loose and trash the turbo. or has that not really been an issue
i worry about this too. but i tried to get inside as good as i could and clean out any wire that went inside and stuff. check out a video i just uploaded i show a little bit of the manifold i built in that video
man this is awesome, relocate and mount your coils down below the manifolds and you would be better off
good job .. I know its a DIY build but wouldnt manifolds flow unevenly, change exhaust pulses and cause turbulence?
nope. the turbo housing and wheel already do that.
can you do this with long tube headers from aftermarket I'm thinking of doing turbocharging my silverado ss
Awesome info and build
How hard would this be with cast iron
did you end up using this manifold?
Atleast hit the rusty cast manifolds with a damn angle grinder before just throwing on your grose booger welds.
Richard
Grose isn't a word
How much are they to make me one for a 2011 Silverado 4.8L?
Is the pipe just standard exhaust tubing you can get from the auto parts store? Literally saw the video and began cutting my stock manifold. I have 2.5” exhaust pipe just wanna make sure I can use it
So when you turbo an LS motor you only use one exhaust manifold?
you're a good lad Justin!
Holley makes new cast manifolds that easily convert.
is it not easier to go around the front if you have clearance
depends on your exact set up and clearances. this is just one option.
+Justin Sane thanks
Do you know exactly what truck eng the manifold you used in the vid came off. I want to try this and want to make sure I get the cast steel and not cast iron manifolds.
pretty much all the ls manifolds are cast steal. just grab one and use it
good info but don't attemp to watch this video if you get motion sickness.
How much you charge for the kit ?
Thanks for the video, looks good
How much for a turbo kit for a mustang with a 347 stroker
Justin Sane..... please email me I have some questions on doing a complete build on a 5.3 avalanche
Cheap and cheerful but would be betting any money on that lasting
I love when people do this lmao
At this point you might as well make a full custom manifold. The entire structural integrity of the cast manifold you just ruined by cutting the spine and adding thin wall tubing. Again might as well make the entire thing thin wall. Just makes it look better and not back yard cheap mechanic.
nice vid ..can I use 2.5 pipe and not 3.0 like u ??
Yes. That would be great for lower hp goals. This one is for a high hp 6.0 set up
+Justin Sane OK thanks so 2.5 pipes would be fine for 5.7 600hp
Eh. That's the upper limit. But yea would work
will the difference. in metal this thicknesses cause a problem with heat cycles does any one know
i heard you can't really weld good onto iron cast manifolds... is it true? Did it crack during this time?
These Mani are cast steel
wow I hit three ads before I even hit half of your video
I however would like to see you build one out of an actual header not a manifold it would flow way better and look better.
ever had a problem with welding cast to mild steel?
+secm207 The issues you're thinking about are with Cast IRON welding and the associated cracking, Cast STEEL like this is doesn't have that issue.
Looks good!
what kit do you sell
You said you had a 110 welder. So the mig works well in this situation?
Yes it's much easier then a tig. But stick could also work.
how much are you selling the turbos for ???
are you running fuel injection if so where would you recommend putting on sensor(s) and would you run one on each bank somehow or just one
+Scott Blessing just 1 for wide band when turbo charged
what do you think about running a turbo off only one side of the engine leave the other side alone?
it's stupid, you're basically doubling the time the turbo to spool up and making the power of a 4 cylinder when you have 8
and you would have backpressure on only one side of the engine. this is a very bad idea and i would highly advise against trying this.
How much for the t4
2 hours. wow. thats pretty fast.
Is the pipe u used stainless?
i have liked the video now you have 1,000 likes! *thanks btw.*
you cant put one stock manifold down and one up. they are either both up or both down
Jessica Jo why not?
good video
how much do u sale it for dont have the skills to make one or the welder same as this for a 5.3 silverado 2000
I don't sell them. this video teaches you how to do it. and all you need is to buy a welder
+Justin Sane oh i see i like it but dont have the skill n for me to go n buy parts n then mess it up jaja i rather buy ones u get me
Just inSane. Setting aside the aesthetics and possible cracking issues previously mentioned, this system will not perform as well as a mandrel bent or weld-el setup that is well designed and built. Granted this is gonna be drastically cheaper, you get what you pay for...
he went 9s on that manifold lol
What type and thickness are you using for pipe?
regular mild in this case

probably a cracking nightmare
hmm I'm sure it does not flow any different than stock
If it works then it ain't stupid, if it's ugly? Well... There's heat wrap for that.
I take it with forced induction you really don't need to worry about equal length tubing?
+snail5341 correct your not using the scavenge affect to draw in fresh air.
+snail5341 equal length tubing can be a bonus but not %100 necessary. Many companies and OEM brands will use a log style or cast manifold with great success at the low to mid range power levels.

Good Stuff!!
do you make anything for c5 corvette
my kits are universal, you build your own manifolds and we supply the rest
+Justin Sane could it work on a 4.3 ls engine? if so how much do you charge?
no such thing as a 4.3 ls. theres a 4.8 ls tho. if the stock manifold is cast steel you should be able to however i believe those 4.3s are cast iron
CrackedIce man I promise you it's a 4.3 ls it's got the sticker on the side of the truck and everything. It's a cast v6 ls vortec block.
Y'all ever welded to cast before? Aint his fault he dosent do this for a liveing. And... no comment on his grinding skills.
Robert Cunningham cast steel these are weldable.
It is weldable just difficult if not heated and when trying to weld cast to mild steel you end up with either cracks or Easley ending up with fighting impurities while welding it
Would you recommend painting the manifold with hi temp paint before wraping them ? I have herd the manifold could rust pretty bad from the heat cycle ,any experience with that ?
they last 20 years or longer oem with no coating. it's personal preference
+Justin Sane ok thanks. What type of metal is the pipe you are welding to the manifold and did you order a kit with all the different bends and diameters ? Great vid btw loved how it looked when finished. Liked and subscribed.
thestig572420 I normally get a universal pipe kit from summit. Stay tuned for more videos showing more about this in the near future.
Some good ideas!
dude your awesome!
good video ignore the haters we know in the real hot rod world perty shiny ant no faster ..look up sloppy mechanics if in doubt haters
is it pointless to put twin Turbo on a LT1 engine
No
Giovanni Crumble its pointless to put an lt1 in anything. Heard of the vortec LS family yet?
what welder do you use
It's a 110 Lincoln 140 amp mig
Not bad but I'll just buy me some 👍🏼
How much is your kit?
+407ForRent hello, we spec each kit per person and their exact needs. if you would like some ball park prices contact us threw www.jsracingproducts.net
atleast this guy knows how to do it lol , practise makes perfect.
TexasGTO LoL fk thats not good ae hahahahaha
Love what you do, just please invest in a camera stand. Making me sick with all the moving around.
Where did you get that turbo from??
I sell them
Justin Sane
I am a professional welder and what is this... "pipe fitters trick"
No real welder would ever refer to himself as a "professional welder"
Fuck that's fucken smart bro
