@notthatjake I just saw your question, for the 2.5 as it is a throttle-cable TB, you would have to find an equivalent 996 cable operated TB, and I'm not sure on the sizing of those. I presume they are larger, but your options are much more limited there, none of the 987 ones will work.

In terms of an adapter, the best option is to use the associated "Intermediate Piece" (I think that's what Porsche calls it)
