So you got it to work by doing what you said above? You just welded the port on the adaptor shut? Partway shut?

Do you have pics of it finished?


Thanks man
Nah I didn't bother to do it yet. Need to find someone to weld it. For now i'm just running the rbc until i finish this..
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..
4.) block off the rear of the plate and done (like pp's 6th pic). i ghetto fabbed mine and it works fine so far. i simply blocked off the rear opening of the adaptor that overhangs with a small piece of aluminum and then mounted the tb.
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

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

I had 2006 manifold in my ep3 k24a2, I just turned my Iavc off in Kpro. To me it idles the same and I can't even notice the difference. Now I have the RRC manifold , still no iavc and idles smooth.
It depends on the adapter you have. The RSX TB with the 02-04 RSX TB adapter to 02-04 RBB mani works fine but on the 06+ RBB mani the same adapter leaves a gap between the Mani and adapter on the backside, so it's been resolved that this newer adapter blocks that gap. It's impossible to not have a leak when you have a huge gap inbetween the throttle body and manifold. It's like having a hole in your manifold and saying, "Yeah I get no leaks bro." It will affect idle even if you disable FIAC, won't matter if it's on or off because it's positioned after the leak. If you don't have a leak you must have the correct adapter, or very insensitive ears.

Sorry I forgot to mention that I was using Karcepts Iavc block off plate to. Thats probably why I didnt notice any vacuum leakes on my 06+ with the older adapter plate.
Aaah, that makes sense.:like: There would be an opening in the back still but disabling the IACV would essentially render it moot in that case

I have something very interesting to add to this thread!!!

Last weekend i picked up a 2007 K24A2, from one of the members on this board actually. Anyway, the engine had a couple of swapped parts on it, "INCLUDING" the throttle body. I have not had time to do any research on it yet, but my engine came with a cable operated K series throttle body that fits right on the newer tsx manifold...i am so curious to find out what throttle body it is. No adapter even needed :p

It could be an Accord, or maybe eve a CRV but I can't be sure.
