Hey guys, so I have to admit, I've been holding out on you guys.
After nearly 10 years of my searching, e-mailing, calling, visiting shops, etc, and many other peoples hard work and persistence, there is finally a production DCOE manifold made specifically for the A20, and at the correct angle for the orientation in our cars.
Here's some pics of the first and only one in existence at the moment. I wanted to wait and let everyone know once I had the chance to install this and test it for real, but it's not entirely fair because I have no idea how long it'll take me to get mine running.
The manifold is a sand-cast 6061 Aluminum manny that used a base stock of a B18, but the flanges have been milled down on both sides to achieve the proper angle without having the full angle cut on only one side (which would have caused too much air disturbance).
The brand: Rowland Manifolds. http://www.manifolds.co.za/
You can get them from Extrudabody here in the US, or order direct from Rowland (they are located in South Africa). I would suggest ordering direct as Extrudabody tacks on a margin for profit, which I can't blame them for. Rowlands prices are extremely fair (almost too low to believe), and the quality of the casting is second to none for a sand-cast. It's not light, but weight on a manifold that's got to be strong enough to hang a set of $1200 carbs without fear of breaking is something I'm willing to sacrifice.
I worked with Rowland (the owner) over the course of months to get this done, and it's finally got a done stamp on it.
