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

No

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)
boost.

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.

At this point I would talk with Scott (PDQSHIP@aol.com)  He is THE
turbo-miester

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