vr4 conv with auto tranny

i either wanna just turbocharge my 3000gt or do a vr4 conversion. the whole awd setup is to complicated and i really dont wanna get into it. will my factory auto tranny be able to handle a vr4 conversion. with a vr4 conversion, wud i have to swap my engine for a vr4 engine or are all the vr4 parts just bolt on type of stuff? what would i need to complete the entire project if the auto tranny works. a bunch of people keep saying that others have done it for under $2000.
