electronics?

I plan to buy a GSR intega next spring, and im going to put a Drag Generation 3 turbo kit into it. I need to know what kind of electronics (ecu, boost/fuel controler, ect) and what are the best? i was looking at the apex controler and a hondata ecu but dont know which type, I have around 1000 - 1500 to spend on it. Any thing you have to add would be very helpful, Thanks. :)
