FMIC vs top mounted
#2
Shorter inlet path, basically the I/C can be right close to the turbo at one end and the other end is straight onto the manifold. Keeps lag to a minimum and is perfectly adequate for a 220-276BHP car.
Once you start going for big power then the capacity of the TMIC becomes inadequate and a FMIC is recommended - but look at the length of the plumbing involved compared to the top-mount!

The top mount on the latest STi's is pretty big, i would expect you could get to 400BHP with that.
Main advantages are as mentioned, it reduces lag and aids packaging. It also improves handling if you can keep the weight inside the wheelbase and is less vulnerable than a Front Mount. You can also run a smaller water radiator with a top mount than a front mount and still have the cooling capacity you require.
It has its disadvantages too, the main one being heat soak in standing trafic.

This is obviously only half of it but I'm sure this now confirms your earlier suspitions
