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.

 

im going to guess around 680cc for just 2 injectors would be good

 

really? you think that will suffice with the supercharger too??

 

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