99 tiburon turbo help

Hey, I was looking at getting this turbo kit for my 1999 tiburon. I know that I will have to purchase a 3 inch catback system and a new clutch. Does anybody recommend any other performance upgrades so that my engine wont get destroyed? I also know that I will need an ecu upgrade. Can any body recommend which ecu?
