This is why I had to cut the heater box out of my engine bay, otherwise on the 16v you can only fit 30mm trumpets with gauze filters.
Now I have 90mm trumpets on with a full size air box

I know the torque thing is a thing. Or at least I know people say it is. But the scream of ITBs is worth at least 30bhp and despite what Americans may tell you power is where the fun lurks.
The top of a 911 engine bay is a fairly cool, drafty place at speed, intake temp isn't usually too much of a worry. At least in an air cooled car.

Concern about losing torque at lower revs due to the shorter induction path, the complexity of moving to Alpha-N, that the current induction system has a snorkel to draw in cool air.
But other than that, with the low-loss exhaust and the lightweight flywheel yes - ITB's should be awesome.
