Default stock turbo elbows...what are they made of? welding wise

anyone know what the stock turbo elbows on say...the ford 2.3 turbos and the 80's dodge 2.2/2.5 TEo4H/TB03 turbos are made of??

looks like cast iron to me but I see a lot of people cutting them at the flange and welding steel downpipes to them.

how exactly do you weld steel to iron lol??

I'm not sure about your first question, it may be cast iron. You can weld steel to cast iron, no it's not the easiest thing to do "properly", but for making at-home downpipes like you mentioned, it is definitely doable.

I used to own a 99 Civic Si, and I built and installed a turbo kit with it. I took a Mitsu 4G63 turbo exhaust manifold and cut off the factory flange that bolts to the head. I also took a factory B18 exhaust manifold and did the same. I mig welded the B-series head flange to the mitsu manifold with mild steel wire, and whala, had a Honda turbo manifold.

Was it the "best" way to do it, no. But, it was cheap ($25 total), did not leak, allowed me to run the Eclipse 14B turbo and o2 housing, and fit great. Would it last forever, I don't know. But, it held up for the year or so that it was on there before I took it all off and sold the car.
