Either go with Mosselman for a turbo http://www.mosselmanturbo.com/ or Kleemann for a supercharger http://www.kleemann.dk/ They both carry kits for the 3.2 engine. There must be a Kleemann distributor in Athens. Mosselman you would probably have to get shipped to you.

the problem with those two companies is that they are exreamly expensive for the hp gains. I still think a custom turbo could be built cheaper for better gains.

A custom supercharger or turbo will be at the end the solution i think. the Kleeman and mooselman kits have a maximum output of 320HP on this engine so it would be again cheaper and better for me if i get my car to AMG in germany and install a 32amg engine with 354HP and i have a guaranty of AMG for the engine transmission and rear axle transmission.

To be onest i would like to have 400-450 HP in this car to be a little bit faster than some M3s and turbocharged like Saxo VTS and 106 Rally which are driven in masses around here and some of theme can reach about 350 hp on 1.6 engines!! (there is also a M3 with 800+HP around here but please lets change subject...! :( )

I feel your pain we have some 800+hp supras here and alot of crazy 1k hp muscle cars (detroit). The supercharger kit would be a great start.
