Welding Questions

I have to weld a couple things to my stock cast exhaust manifold.

  1. 1/2" thick T3 flange
  2. Wastegate flange

My concern is the turbo flange. It’s going to be welded to my current T3 flange to act like a spacer. Or, instead of welding it on should I use extended studs and an extra gasket? If I do weld it, what is the best way to keep it from warping?

The wastegate is a different story, I have to drill a hole in the top of the manifold and weld in a pipe with flange. I might outsource this to Hank or something.

You can always bring it to me ya know :wink: Weld the flange on AND use extended studs. Just no double gasket. Too much movement and it’ll likely blow out.

Is this manifold cast iron or tubular steel?

It’s a cast manifold. I’ve been trying to find extended studs, preferably ARP. I believe it’s a M10x1.25 about 60-70mm long.
