STI version 4 motor/ what turbo?

hey all
what turbo is on the version 4 STI engine

you know, the 270 HP 2.0 litre from japan

a buddy of mine just ran into one and he is willing to give me the turbo on it. does it work with stock ej20 injectors? would all i need is a good tuning session?

thanks for the info
