Help Needed Upgrading Blown R33s2 Turbo

[kounj002]

Hi I recently blew the standard turbo in my r33 s2 and am in need of some help/advice. I would like to know what is involved in installing putting a larger sized turbo that will bolt strait on with minimal changes. I realise Ill have to change my fuel pump which needs to be done anyway but this aside what if any other issues are there?.... im thinking along the lines of a 450 550hp Garrett .No experience with turbo upgrades so any help or turbo recommendations would be awsome !
