Here for sale is a T3 Turbo manifold I built for my Turbo E320. It is compatible with all chassis, some m103-24v's, all '94-'99 M104's and uses a 38mm waste gate. It's covered in surface rust minus the welds which are stainless steel but I can knock that off and ceramic paint it for $25.
$425 firm. If you have a W210 I have the wastegate dump tube available as well. It's TIG'd stainless.
Definately had some fun with this thing. Actual video of the E320 with the manifold in question.
