heres mine. nothing speciall just 1.5" weld els. this view is from under neath so you can see how i reversed the #2 runner into the turbo so the airflow is better into the turbo intake from the log.

here it is on the car. Very tight compac manifold. note the relocated power steering intake hose.

this manifold has been on the car for 7 years now and not missed a beat! i havent even had to retorque the turbo or manifold studs and nuts!

Look at the head itself and see where you can leave material. It wont add cost to cutting the flange and having a little more meat on the head flange will help both with welding and even torque over the flange once your done and tighten it down. If its laser cut the extra girth in the flange will keep warping down too.
Cut the overlay flange you just posted.

Strange as it is but I pay for laser work by the Kg so it doesn't hurt to add a few curves.
4sfed5 your manifold is what inspired me to try and make my own. It is an elegant design. +1

This is the start to an interesting series where a log manifold is constructed for a TD04. Note the asymmetrical outlet flange location to move the Turbo forward. This also discusses how to clock turbine AND compressor to allow wastegate controller to not need a new bracket. Of course, it limits the direction of the compressor outlet.

If you have cad, just run the exhaust gaskets through a scanner, xref the scanned tiff in, scale it off a few points and then trace it.
Print off a 1:1 scaled print of it to verify and your gold. shouldn't take more than 15 minutes.

First manifold is getting there. I am learning how to use my new HF band saw so my cuts are by no means perfect yet. Tomorrow hopefully I will get it all good gap wise and get some tack welds on it.
