When will all the newbs learn that it is cheaper to just buy a 4g63 powered car than to try to swap one in. Argh use the search function and learn a few things before trying to take on an endeviour that you can't handle with your obviously limited knowledge and skills. Do you know what fabrication is New guy? It is what is required to install a 4G63T into a car that originally came with a 420a.. You have not done your research if you are even asking about trying this swap!!! Now sell your RS to someone who knows it's abilities and buy a GST if you want a factory turbo.... If you want to turbo your RS Buy a kit from Hahn or Star and boost the 420a.
