I got mine working great.

Things used:
Cereal Box for gasket material
High temp gasket maker to smear over cereal box material
Dremel
Time and patience

Used a dremel to round or bore out the lower part of the hole on the intake manifold. Even after doing this the hole on the adapter plate for the IACV still did not line up 'enough'. Then I rounded out part of the adapter hole so that air can rush upwards into the new opening on the intake manifold. Lastly, I made my own gasket so that it can act as a seal to block off the remaining opening in the adapter hole (due to the 06 manifold not having material there). If you don't do this you will have a big vacuum leak. Hope this makes sense. I didn't know if this would work so I didn't snap pics.

BTW, before this I had tried disabling the IACV through KPro and it did not help but thanks to all who suggested to try it.

Sorry to bring this back, has anyone found a solution to running 06+ manifolds with rsx-s TB? I'm in the same situation and cant seem to find a solution in which does not involve me making some kind of block off plate from scratch..
Three solutions from least work to most work:

1.) Buy 04-05 TSX Manifold

2.) Disable IACV function in KPro and adjust idle mechanically at the throttle body

Refer to step 4 of this to do so http://www.k20a.org/forum/showthread.php?t=68845&highlight=iacv+karcepts

3.) Create an opening at the 06 TSX manifold inlet for IACV. Which is hard because there is not a lot of material.

From the ded. Did anyone find a more practical solution to this issue? And for those who rigged it, how is it holding up? LMK Thnks Guys. I was on the verge of purchasing the 04-05 manifold, but I figure why not mod? I would save much more by modding, and additionally the 06-08 intake piping increased in diameter from 70 to 80mm so that should make a significant difference. Enough to keep the 06-08 mani. Sucks I just sold my 05 TSX. Should have kept that mani haha
Mine held up great right up to the point I took it off to supercharge the engine.

Tis has been solved! Just to make it official. 6SPD_EK told me about this new adapter from Karcepts. I spoke with them and they said they have yet to advertise that it actually has the provision for the 06+TSX Manifold! Here's the pic that 6SPD_EK posted in a similar thread. It's upside down of course haha
