Re: Welding mild steel to cast
Well I'll bite the bullet and give it a try. I gotta pull off the intake manifold and header anyways since I have a new headgasket and intake/exhaust manifold gasket and some ARP head studs. So this will let me get the chance to mock things up with it's taken apart waiting for the stuff to come. I'll post some pics later this weekend.
John you should call it the "hotrex".
How am I half assing the manifold? I'd say that people who boost a L series in a Z use the 280ZX manifold cause it works just fine and can get good numbers out of it. It's not like a honda where everybody and their mothers make flanges and ---- for it. I can't think of a company that makes tubular L series turbo manifold and there would be one. Holy hell I couldn't or wouldnt want to imagine the price.

I still suggest using a nickel alloy or brass alloy to be on the safe side.
"When welding cast iron, the major problem is to avoid cracking the cast iron, or leaving it with locked-in stresses that might cause cracking in service. When welding cast steel, you normally need not worry about cracking, but you must be concerned about distortion, since steel will stretch – become permanently elongated – before it will break. Distortion can often destroy the utility of a casting just as completely as cracking."

How did you prep the cast before you tigged it? What kinda amperage are we talking about here?
I tried it once but the cast just popped all over the tungsten. However, I didn't grind it down or anything.
