A smaller intake manifold, a smaller exhaust system, and the factory tuning limit the power in the 3.2.

I dont think the 996 intake manifold bolts onto the 3.2 head, I had to drill my 3.4 heads to accept a Boxster intake manifold ( I didnt want to lower my engine 1.5" )

Once my 3.4 swap was complete with a boxster intake manifold and exhaust system, I was very disappointed with the power. Replacing the entire exhaust system with a full NHP exhaust really unlocked some power...I was only expecting a 5-7hp increase, but it felt closer to 20. Im sure the 996 intake manifold will give another solid increase in power...

So I agree, the restrictions of the 3.2 are the complete intake and exhaust systems.
