Injector Size for SP12 with throttle bodies?

So I'm considering purchasing IDA throttle bodies from tweakit.net or similar places, but I was woundering what size (I was thinking the 50mm would do nicely) but mostly what size injectors to run for primary and secondary. Also i will be using this setup to be supercharged later on so what size would i need to get for that.

Lastly they offer Japanese and Bosch type injectors? I've always had good luck with Bosch stuff before but wanted to get your thoughts on this.

i think you'd at least want 4x550 if not larger, 4x720 or 2x550 and 2x850
