Where can I get a Steel S400 Outlet flange w/ Oring?? I was lookin and found one for $70. I think thats kinda high.
yes you need vband with oring for the compressor discharge
Can you weld Stainless steel to aluminized steel?

look for the GT 42 parts, it can be had in steel or aluminum depending on boost tube mat'l.
I replced the o-ring on mine cause the original was a little cheesy thing.
Good luck
