The Project Pad

I would have been all over that . Stainless pipe scraps are hard to come by because I try not to waste it .
Used to be able to get it from work but now they donate it.

Manifold is almost done . Welds are marginal ha.

Looks great! You should be proud of it

Heck yeah! Nice work!

I’m definitely happy with it for the first one, it will certainly suit my needs .
Flange is just tacked on right now for fit up.
Took probably a day so far , around 8 hours to fit up and weld the runners . I think it would take me a full day to make another one . I would like to either replace or remove and coat the one in my URQ as it’s carbon steel and looks like shit already with only 1300 miles on it .


I just did this however it was convenient, and this wouldn’t be for a twin scroll , but I may have to look at which or if certain runners should be merging together in any particular firing order or if it matters .
It can see there would be quite a few different ways to lay it out . Also different merge angles, this is a 12 degree, pretty tough to weld .

Very nice!!

Ideally they would fire into the collector adjacent to each other in a circular motion to form a vortex.

I think 1-2-4-5-3 can be done. I made about 3 collectors so If I want to make one differently I can. Have about 3 cars that could use headers.
I mocked this up using a EWG indy 7163 but I really need to get my hands on an IWG turbo that's slightly larger so I can see what space I would have .

Here’s the next step. The flange isn’t done yet for two reasons ,
The first is that it’s 304SS but the manifold is 321. I think those two metals can be welded together using 308L Filler but I need to look into that .
The only source I have found for the flanges is in like Sweden but I’m working on drawing them in CAD so I can have a local place cut them because I’m sure at some point I will want to remake or change something . I have intake and exhaust drawn just not tested

Second reason , it’s not flat . Like right out of the box the flange is already warped . So I’m making a fixture for it . It’s milled perfectly flat, and I’m thinking if I can get just the right dia metal legs for it I might be able to bend and rotate it from side to side

I wish I had fab skills like some of you guys. I guess I’ll live vicariously via the forum. Nice work!

use 308 or 316 filler for that.

I never have been trained on any metal work or anything but wanting to mod my Audi’s forced me to start making stuff because the parts that I wanted were not made available or required welding (like coilovers for example ) or I couldn’t afford them if they were . It’s been a long process to even make something I’m willing to show to people ha, especially when welding stainless is involved . But everyone has to start somewhere . I don’t save money doing it or anything but I get time in my shop and learn stuff

Amen to that!

I was almost there once. I had a project YJ that I wanted to make bumpers for. Bought a used Hobart mig welder. Sold the project, the welder sat, didn’t have enough space, and it got sold too. Not that a mig welder can do this type of work, but it would have been a nice skill for me to learn. Someday I want a dedicated shop (that I can’t afford) for all of the tools (that I can’t afford) for all of the projects (that I can’t afford)...someday. lol
