DIY Tubular turbo exhaust manifold

[gixrman]

I TIG welded it, I have a Miller synco 200. Tubing dia. was 1-1/2", I bought a bunch of U bends and cut as needed. The hardest part was the collector. If I had to do it all over again I would have bought a pre-fab'd T3 collector and started from there.

Do you remember what the thickness was? I'm thinking I'll be safe with something around .095 or thicker. Also, did you ceramic coat it or wrap it? I would buy a pre-fabbed one, but I think I'll make do with what I have. Thanks for answering all my questions.

You want sch10 stainless. It is cheap enough to practice on, if you want a manifold do it right.

I too am looking to build a twin scroll manifold for my hx35. This King Architectural Metals wrought iron metal balusters finials casting steel ornamental forged gate fence stairs Access control is what I am going to use to build it. I also have a good size piece of 5/8" plate that I'm going to make flanges out of. I'm going to build a jig to weld it together on and to position the turbo to clear the factory fans, motor mount, water pipe and try and get as much clearance as I can for the exhaust. I will be welding it with a mig and it will be ceramic coated when finished. I will be bracing as necessary for it to be able to support the weight of the Holset also. With proper bracing and ceramic coating, I believe it will be able to live a long life. Now it just needs to warm up a little bit, it's too damn cold to work in the garage right now.

Wow good find. That looks like just regular 1.5" sch 40 pipe. Good luck on your build, definitely keep us posted.

was the tubing 1-1/2" interior diameter or exterior diameter?

thanks,
John

There's a guy on the local forum that makes BEAUTIFUL manifolds. Everyone knows him as "Fathouse", and his manifolds are so well known when people ask what kind of manifold you have you say, "It's a Fatifold" Here's some pics.

Thats a pretty sexy manifold.
