2002 Avensis D4d 2.0

[Sayam]

Hello,

I wondered two things about my dad's car. I've not passed my driving test yet, but I'm going to take the Avensis of my dad when I do as I've driven it and I think its an awesome car with good torque output.

1) Is there anyway to improve the audio system without fitting aftermarket CD player? I dont want to do this because it then means that the satnav/mpg computer etc all go out of action as its all linked.

2) is it possible to fit a bigger turbo or induction kit to get the engine from its current (115bhp, my approx guess) upto around 140 or higher?

thanks.
