Hmm my RX8 TB picture wasn't posted here well from the video you see we just drilled the rivets out of the rx8 TB that held the circuit board on and replaced it with the Scion TC circuitry. They are exactly the same in dimension and function but the RX8 TB electronics were apparently fried so it was unrepsonsive. That was the reason for the switch of circuitry.
As to how I mounted it I got a 4x4x1 piece of 6061 aluminum from onlinemetals.com for $33. I then made gasket templates by simply brushing black paint on the surfaces of the TB and Intake and pressing gasket material on there to make an outline. I cut the gaskets out with an exacto knife and traced their outlines and holes onto the metal starting with the RX-8 side. I used a 57mm hole saw to make the intake hole and rotated the piece on a 4" bench grinder to make a 'funnel' shape on the RX8 side to match it's 70mm size. After that I got a 1/4" tap set and drilled and taped the four RX-8 TB mounting bolts, drilling about 3/4" down into the metal. Then I moved on to the intake side which I had to be careful with because I made the adapter AFTER I put the damn engine and intake in. If I did it all over again I would have made the adapter first and made sure it fit 100% and THEN dropped in the engine and intake.
You have to be careful that you position the aluminum piece in a way that it doesn't conflict with the intake.
Despite the pic, I used 1/4-20 thread bolts instead of the studs. The nuts proved too hard to get on so I used allen socket bolts and lock washers.
We also bypassed the coolant lines that go to the TB and the fuel vapor thing.

No, four to one equal length with a merge collector.
granted this is not a tc header, but the design would be optimal for NA build
like so
