Fuel injector color codes?

[Diz]

Is there a list somewhere that identifies which color injector is rated at what flow volume in CCs? I know the blue tops are 450cc for instance. I just got a set of yellow tops that are supposed to be 550cc and I saw some red and orange injectors at the wrecking yard on smaller Mitsubishis...

actually yellows are 510's. its hard to tell.. if you're looking for performance injectors,do yourself a favor,buy aftermarket,they are so cheap these days.
