Default 1997 A4 1.8T Turbo replacement

I want to replace my stock 1997 A4 1.8T turbo and had some questions...

Is the stock replacement a "K03", or is that an upgrade?

What other items do you recommend replacing\servicing during the turbo replacement? I was thinking I would install a new diverter valve (Bosch 710N) and N75 wastegate valve.

Can you upgrade stock 1.8T turbo to a K04 without anything other than a performance chip? Would the K04 upgrade require a specific chip?
