Turbocharging an Audi

hey,
i was really wondering whether you could intall a turbo into any 1997 AUDI A4 Quattro 2.6L (non-turbo). also i was wondering is it possible with any non turbo Audi A4's to install a turbo?

thanks

You can turbo charge anything with enough $$

By the time and money you spent Turbocharging the 2.6 it would have been cheaper to buy a S4 and have money to tune that.
