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
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 .
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.
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.
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 !!
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
You obviously have not built any high hp manifolds first clue using sto k manifolds which in the case of the build it is all in what you want for the end result I have built enough turbo and long tube, fender ,hood zoomie,bottom exit headers in my life out of all types of metal in your case if u feel that the chance of weld slag or a weld bb going threw ur turbo and having a serious weak spot where u fill in gap with mig weld is ok then who am I to tell u different . All I can say is when you build your first set of stainless or titanium turbo/header with a tig all these short cuts will be a total nightmare for you. My dad taught me at a young age if u are doing it now you might as well do it right the first time or it will teach you the second good video keep on practicing you will see what I mean some day
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!
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.
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!
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!!!!
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.
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 ;)
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...
Honestly why anyone would pay for this is beyond me. Im not usually one to hate, but this dude doesn't even clean is weld surfaces before welding. Short cuts on short cuts on short cuts. "The bitterness of poor quality remains long after the sweetness of low price is forgotten."
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
