DIY Turbo Manifolds from Stock Cast Manifolds

- Опубліковано 11 жов 2024
- Using a stock manifold as a turbo manifold is a good solution in many cases, especially with doing LSx stuff. Here’s a quick video of me adding V-bands to some stock cast manifolds.
tip for v-bands is to weld with both sides connected with the clamp so there is no warping , keep up the great work!
You are right!
Thanks a bunch for sharing! I was wondering how to do exactly this... Cast to stainless. Thanks again, you have helped me a bunch on my project.
Just to be clear, this cast steel, not cast iron. Cast iron has a different process. But for this, heat the cast to about 400lbs. And use stainless filler rod to weld the stainless to the cast steel
@@vazfx16 thanks again!
Pretty good video, dude. Really helpful for me since there's virtually no aftermarket turbo headers for the Dodge 3.5L V6. Of course I wouldn't use the V-band on my stuff though. I would actually just use a T3 or T4 bolt flange.
Same boat here, I got a 3.8 v6 mustang and nobody really helps out. I have equal length headers in the car so I’m messing around mocking up with the stock headers in the garage to show a shop what I want done right. This video was great
Really nice job and I enjoyed watching. Thank you very much.
Thank you
@@vazfx16 I've watched some other videos of yours and I'm impressed with your skills.
I'm thinking about making some tubular control arms and that's how I found you.
I'm 62 and can weld but I was never great at fabrication and you helped me in seeing what I need to concentrate on my build. Thank you again.
nice work... finished product is definitely clean and professional looking. any chance you could point me in the right direction to find a pair of SBC cast steel manifolds? oh... and it was nice to see I'm not the only one getting creative with lumber and other random 'innocent bystander' items around the shop to find a cool and comfortable perch for my hands! although I ditched the standard issue leather/buck TIG gloves years ago
What are you using for tig globs now?
I don’t know about cast steel manifolds for the first gen sbc…I am an LSx guy. Before the LSx, I did imports. You may have to buy and aftermarket manifold for an old school sbc, I think factory was cast iron
👍🏻👍🏻
Great video man, I've been following you on the gram too. Would you mind sharing your settings and material on the TIG?
Thank you
I don’t remember the exact settings for this project
But:
Be 308 Stainless filler rod
DC
Thoriated tungsten
Did you bevel the mating surface of the manifold ? Or just a good clean butt joint ? I'm about to be doing the same on my manifolds. And this video really is very helpful. That's the only question I have.
The manifold side was a bevel, so there was space/gap to allow the weld to fill. I don’t thing a straight butt weld would be strong enough
@@vazfx16 I believe you are absolutely correct. Thanks for the info. I'll be doing mine soon. So I can relocate my turbo under the hood.
im planning on doing this too, just on the other side of the flange so im not welding cast, but what size v band flange did you use?
I don’t know the size of the v bands. This was for a customer, and he brought them ready to set up
It's cast steel, welds the same as mild steel
Hey man I'm trying to figure out if the cruze turbo manifold is made of the same stuff as this and if I need to both with all the preheating and stuff?
I don’t know the composition of the Cruze mani, but any time you have a thick piece, it’s always good preheat. It mean you are start the weld from 300 degrees or so, instead of 70(room temp). It makes for better TIG welds since you can get a weld pool started quicker and more effectively. It keeps the heat from being sucked away from the weld pool
What do I do with that open piece that sticks on the side on the right manifold in the beginning of the video
I plugged it with a piece of stainless rod, snd welded it in place
Isn’t that weld susceptible to crack? Dissimilar metals, and also no preheat.
They are both steel. You are probably thinking cast iron.
Tell me more about your experience building these and them cracking?
@@vazfx16 not trying to make any offense, I’m just a union pipe fitter that welds the high pressure piping in nuclear power plants🥴
@@TheSuperRandomShow1 Totally apples to oranges comparison
Thanks for the comments.
What size v bands did you use?
Oh man. I don’t remember…it’s been years. Was for another person’s project
No pre heat or controlled cooling? And will this hold up overtime? Planning to weld an cast turbo to an cast mani....any tips?
This is cast steel, so it has different properties than cast iron. You can weld it like steel.
@@vazfx16 how do i know the difference?
