500cc/min fuel injector source???.....

[knightly]

where can I get 500cc/min fuel injectors from?....as a guide - something at about 400cc/min @ 3Bar will do, as that equates to about 500cc/min @ 5Bar ..........a mate needs some for a supercharged cozzy V6, and is struggling to locate them - they need to be traditional end feed, and of the high impedence variety?......new or second hand will do......
