nyspeed help me decide!

the car will put down over 400 as of now on the juice. the car is ready to go for a new turbo it has everything it possibly needs for the next step. i can run a new turbo on the stock ECU without a problem but it will kinda restrict power that could be brought out. i can get the EMS for $1600. as for me im leaning towards wheels right now and ill save the EMS for over winter, i want to see what the car will do at the track this year with my current setup and if im not satisfied ill go from there.
