How to make your own LSx Turbo Manifolds

small video on how to save a ton of cash by building your own manifolds.

[@bowtie406]

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.

[@mrmidnight32]

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

[@ketsjupelvis]

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.

[@kaleg.416]

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

[@yangadiplo3850]

Thanks for showing how you did your setup. The idea is priceless.

[@irish-simon]

great job love seeing the homemade/cheap way to do things yourself and the smile you get when it works is cool

[@GnarlyBlade]

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 !!

[@brauliovera5733]

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.

[@937McLovin]

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

[@tomeighty]

Great video, thanks for taking the time to show all of that. Tom

[@-CLASSIFIED-]

couldnt you use a 6.5 diesel manifold set and work around the clearance issues ? if i recall correct they should fit

[@edrose122]

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.

[@dekzzx]

love seeing stuff like this so cool

[@slowcar6460]

Thanks for the video, looks good

[@davidlamond8994]

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

[@idriwzrd]

Nice work, very resourceful. Where do you get your bends? You need a workbench.

[@TRX450RVlogger]

Looks good!

[@RibbedGiraffe]

How long did this hold up before the welds cracked?

[@TheChrismanis1791]

im curious on how its holding up with just that exhaust tubing.

[@1flynlow]

how long will this steel last with the turbo heat

[@bencowell1790]

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

[@n5yiz]

fuck...half the people on here don't even own a set of tools. hahaha

[@brandonspence2189]

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.

[@goodfellasinc.5648]

ben cowell there junk just go buy them for 150 3inch at yearwood

[@backyardbuilttrucks1]

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 .

[@blakeschneemann6276]

what did you use to cut the manifold?

[@tyrannosaurusmex5033]

Awesome info and build

[@d.j.9961]

depending on cost,i would like to see a manifold for a 03 focus zetec 2.0 dohc vin 3 $$$?

[@jthrill2262]

can you do this with long tube headers from aftermarket I'm thinking of doing turbocharging my silverado ss

[@ericperry4934]

What year and model of the MANIFOLD on the right you already cut, angular the v band? Smaller one

[@em6132]

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!

[@kevinnearhood641]

Looking forward to the S10 build.

[@themagicm]

Looks good. If you blend it, shoot some high temp paint, it'll look bad ass. Either way, I did something similar.

[@Kliphmusic]

you're a good lad Justin!

[@idus]

dude your awesome!

[@donnyjohnson2017]

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

[@Cracked1ce]

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

[@nickmccarthy8002]

As long as your expectations are really really low, I’d say it’s a win!

[@italianrelic]

So when you turbo an LS motor you only use one exhaust manifold?

[@EGGINFOOLS]

I wanna see how you fill the gaps between the turbo flange and outlet from the manifold

[@bendiesel4446]

looks good I have a sloppy 7875 kit and looking at making my own hot side

[@stevenyates715]

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 ;)

[@hugoariasify]

Good Stuff!!

[@GetItAtWiLL]

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.

[@Cracked1ce]

pretty much all the ls manifolds are cast steal. just grab one and use it

[@cmsracing]

Some good ideas!

[@d.j.9961]

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!!!!

[@lilblessing]

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

[@PROJustinSane]

+Scott Blessing just 1 for wide band when turbo charged

[@fastcash9799]

Is the pipe u used stainless?

[@SR20FTW]

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?

[@Cracked1ce]

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

[@awsomalx]

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!

[@SNIP3RT3CH]

good job .. I know its a DIY build but wouldnt manifolds flow unevenly, change exhaust pulses and cause turbulence?

[@PROJustinSane]

nope. the turbo housing and wheel already do that.

[@watahyahknow]

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

[@bryantramirez742]

What 110 welder do you have?

[@BigRichEHhthang100]

How much you charge for the kit ?

[@robertz5421]

i have liked the video now you have 1,000 likes! *thanks btw.*

[@JoseGarcia-kq1bt]

did you end up using this manifold?

[@alfredodimatteo2850]

i heard you can't really weld good onto iron cast manifolds... is it true? Did it crack during this time?

[@thestig572420]

These Mani are cast steel

[@obedm.6627]

Fuck cut to the chase.... "but what I'm going to show you today". Jeezzhh

[@christophercritton7175]

You said you had a 110 welder. So the mig works well in this situation?

[@PROJustinSane]

Yes it's much easier then a tig. But stick could also work.

[@fordnorriss]

How much for a turbo kit for a mustang with a 347 stroker

[@TACOMASRT5]

How hard would this be with cast iron

[@ls4.8frank]

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

[@my1stbabygirl2012]

how much are you selling the turbos for ???

[@martinez1701a]

what do you think about running a turbo off only one side of the engine leave the other side alone?

[@ImElkay]

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

[@Cracked1ce]

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.

[@TheMikesylv]

will the difference. in metal this thicknesses cause a problem with heat cycles does any one know

[@theuprightman8446]

good video

[@Procharged32]

Holley makes new cast manifolds that easily convert.

[@ls4.8frank]

How much are they to make me one for a 2011 Silverado 4.8L?

[@jononame8915]

man this is awesome, relocate and mount your coils down below the manifolds and you would be better off

[@calerudy1436]

what kit do you sell

[@aHowToYouTo]

shes aint pretty but she will work for a fraction of the price thanks for making the video

[@theuprightman8446]

is it not easier to go around the front if you have clearance

[@PROJustinSane]

depends on your exact set up and clearances. this is just one option.

[@theuprightman8446]

+Justin Sane thanks

[@thatc10]

good info but don't attemp to watch this video if you get motion sickness.

[@Mr_getinthere]

nice vid ..can I use 2.5 pipe and not 3.0 like u ??

[@PROJustinSane]

Yes. That would be great for lower hp goals. This one is for a high hp 6.0 set up

[@Mr_getinthere]

+Justin Sane OK thanks so 2.5 pipes would be fine for 5.7 600hp

[@PROJustinSane]

Eh. That's the upper limit. But yea would work

[@MyConor1]

Practice makes perfect ....

[@mytymse]

What type and thickness are you using for pipe?

[@PROJustinSane]

regular mild in this case

[@jbamflanderos]

Justin. ...you still got that Awd civic bro.......

[@thestig572420]

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 ?

[@PROJustinSane]

they last 20 years or longer oem with no coating. it's personal preference

[@thestig572420]

+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.

[@PROJustinSane]

thestig572420 I normally get a universal pipe kit from summit. Stay tuned for more videos showing more about this in the near future.

[@secm207]

ever had a problem with welding cast to mild steel?

[@user-zj2mb3sp3x]

+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.

[@michaelgearhart6685]

Justin Sane..... please email me I have some questions on doing a complete build on a 5.3 avalanche

[@armyblouvet54]

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.

[@Cracked1ce]

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$

[@civicmag1]

what welder do you use

[@PROJustinSane]

It's a 110 Lincoln 140 amp mig

[@markdavidson1991]

Cheap and cheerful but would be betting any money on that lasting

[@harrisonp3727]

cool

[@richardguilfoyle8276]

Atleast hit the rusty cast manifolds with a damn angle grinder before just throwing on your grose booger welds.

[@rayschrum5855]

Richard

[@wheels.and.wrenches]

Grose isn't a word

[@nitrousshovelhead]

2 hours. wow. thats pretty fast.

[@hammatime94]

If it works then it ain't stupid, if it's ugly? Well... There's heat wrap for that.

[@TheJorge327]

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

[@PROJustinSane]

I don't sell them. this video teaches you how to do it. and all you need is to buy a welder

[@TheJorge327]

+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

[@jaime13huerta]

Where did you get that turbo from??

[@PROJustinSane]

I sell them

[@Sizzer_Me_Xerxes]

Justin Sane

[@eddiebowen7194]

How much for the t4

[@DanoAuto1]

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.

[@adrianrubi6345]

19:40 Cuando te das cuenta que te comiste un cable.

[@LuisGutierrez-pm2eq]

Fuck that's fucken smart bro

[@sansui1968]

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

[@jevonmayo3646]

hello just ceen ure nice hook up . i have a 81 chevy el comino that im putting a 5.3 vortex in it with a turbo canbu give me sum pointer please. thanks

[@firemanjim324]

Yeah, learn English.....

[@wkeil1981]

do you make anything for c5 corvette

[@PROJustinSane]

my kits are universal, you build your own manifolds and we supply the rest

[@loganmilliner8734]

+Justin Sane could it work on a 4.3 ls engine? if so how much do you charge?

[@Cracked1ce]

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

[@loganmilliner8734]

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.

[@anthonydomanico8274]

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...

[@antoninomorales]

he went 9s on that manifold lol

[@dLikesDDs]

probably a cracking nightmare

[@mrmidnight32]

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.

[@snail5341]

I take it with forced induction you really don't need to worry about equal length tubing?

[@PROJustinSane]

+snail5341 correct your not using the scavenge affect to draw in fresh air.

[@zososldier]

+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.

[@Cracked1ce]

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

[@NO-background-music-in-videos.]

Love what you do, just please invest in a camera stand. Making me sick with all the moving around.

[@dangerousfreedom4965]

How much is your kit?

[@PROJustinSane]

+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

[@jessicajo1801]

you cant put one stock manifold down and one up. they are either both up or both down

[@rickbean4097]

Jessica Jo why not?

[@5150on420]

wow I hit three ads before I even hit half of your video

[@Ebackfive]

is it pointless to put twin Turbo on a LT1 engine

[@fishin4cougs809]

No

[@beverlyweatherly5036]

Giovanni Crumble its pointless to put an lt1 in anything. Heard of the vortec LS family yet?
