Porche brake swap???

Since I know we have pretty much the same car and you all golf owners don't look much in the rabbit section but here is a question about my rabbit...

Any one have any quick info on putting a 4 disk porche brake system on my 84 rabbit conv? I want to do it so bad, but am tired of researching. Any help is welcome. As well I take it i should switch out the brake master as well?
