Source for weld els
So I'm planning on welding up some bits of my manifold, and I found these guys: 90 Degree Black Steel Elbow
According to their helpful chat people, they're schedule 40. Is that the wrong metal to make a manifold out of? I'd go with stainless, but I can't back purge, and I've never done SS before (I hear she's fickle). On a side note, is 1 1/4 big enough for an SR20 T25? I used a calculator a while back and found that the elbows flow more than the head (under flow bench conditions), so in theory I should be fine, right? |
sch40 mild is fine
1.25 is plenty |
Local industrial supply house can be a source.
There are head flanges that are made for 1.25 that transition from oval at head to round at elbows / tees. |
Yeah those are neat.
And for some reason the local places for me were much more expensive than ordering online and shipping. Stupid overpriced CA. And the stupid tax we have |
Those look exactly like the ones I get from my local plumbing store. They are also about the same price. They will work fine for whatever type of manifold you are trying to build.

Thanks guys, I'll order them now. I'll post some pics once I get them jigged and tigged

acestainless (now ace race) was the cheapest for me. But that was sch40 304. You'll want to call BMC race and have them custom make you the flange for that size pipe so you dont have to deal with crushing and bs.

My only worry is that I'm using schedule 40 while these might be for sch 10. I doubt a little porting on the inside wall will hurt anything edit: links are working now |

I actually shot him an email already after I saw someone here get a premium flange that looked really nice. Seems like a small operation he has going on, and I like supporting small business, but I found this: Exhaust Head Flange - Mazda - Mazda Miata 1.6 Exhaust Head Flange and now I hear they don't fit...
