Best thing to do is fit a set of 3.0 cams :y

If you fit the 3.0ltr cams while your doing it fit a 4 bar fuel pressure regulator  to help cure the flat spot . I did and wow it makes a diff and you get an extra 20bhp. :y

The 3.0 was produced briefly with a low pressure turbo.
I say briefly because it had a few problems.... ;)

As others have said, fit a set of 3.0 cams, and then you can "chip" it for a bit more power.

But first give it a full serive and clean all the breathers and change the fuel filter. You will be suprised what a difference this can make. :)

Contact www.jam-sport.co.uk (01604 755529). They have a supercharger kit for the 2.6 V6 that's supposed to be good for 246bhp and 233lbft of torque.

I wish we had resources like this over here.

Interesting. I wonder why they didn't start with a 3.2 in the first place though? :-/

Yes. Either that or they had to ditch the dbw and put a manual throttle body on it?
