Just curious why the design of the Cup car airbox is as such. Looks smaller than the OEM but I'm sure it's far more efficient. Or is it intentionally restricted?

The MkI airbox which is essentially the same as a 996 Cup car airbox, is part of a "complete system", in that it works only in conjuction with the cup car decklid. So although the airbox itself is smaller there's more of ram-air effect as a result. The air travels in a more direct route.
That said the MkII airbox seems to be allot closer looking to the street car. They look the same as far as I could tell.

I had hoped that perhaps the "RS" intake would be a bolt-on upgrade for the lowly GT3, sadly having looked at an RS close up, the decklid is substaintially different such that you would require the lid and the

Ive been dealing with a company making ^^^^ for me. Its a 100% copy of the OEM RS MK2 wing. Fully adjustable wing, just like the OEM one. My wing will be 100% carbon, and decklid FRP.
Another company, FVD, has a similar one, but the wing is not adjustable, and do not offer the wing in carbon only FRP.

I am digging this post up because I was wondering if you would have to have the entire decklid for this CUP style intake system?
Or is it there just the bottom panel that can be epoxied to the stock deck?

.2 RS and .2 Cup have essentially the same airbox. Only difference is the badging on the box. And Cup doesn't have MAF sensor so there's no screen in the plastic tube. You can install a MAF sensor into the Cup screen-less tube but the engine will idle stumbly and will get a MAF fault code. I've tried it.
.1 GT3/RS and .1 Cup have way different airbox designs. I guess the biggest challenge if one were to put .1 Cup airbox in a street car would be where to put the MAF sensor and will the location produce proper MAF signal to the ecu.

Very nice MJSpeed!!!
I can't see from the photo, did you use mesh screen for the MAF sensor? My car got the fault code without the screen. No more fault code right after adding screen.
