Rb20 is a decent motor. The stock turbo is no good however. What all would it come with.

Question for you is what is this car going to be used for? It really comes down to what you want to do with it. Parts for the rb aren't cheap or easily accessible.

I personally would rather rebuild the ka and go turbo. Parts are cheap and readily accessible for the ka and the motors themselves are everywhere.
