Well that's a Turbo car. Besides you mention that you can only get 91
octane, that in itself is going to lower the engines HP

Hunnh??!?!? Retarded timeing makes a engine make less HP not more.

The K&N Will not help your turbo spool up faster.

In a word no. Cooling the IC won't help your low RPM Torque. It might
help you high end HP but I doubt that you'd feel it with normal (1.4 Bar)

It won't fry you engine but PDQSHIP and I have been running the stock
intake system and it works real well for us. (PDQSHIP Has 350+ HP and
I'm not far behind)

You answered your own question.... The highest Octane that you can get is
91. If I put 91 in my car (With Neds 2.0 Bar Box) I would Ping the motor
to death. Unless you can get higher octane don't expect to put any more
boost on the engine.

have fun with that one but If I remember NOS and Turbos don't mix..... I
