Just got a look at mine, they're color-coded yellow. What are the possible makes/capacities, really trying to figure out what's on my engine!!

I Think they are 550cc mate

Yellow are Unisia JECS 444cc standard injectors. Great pattern and atomisation, will just about support 450hp if you have a really good set.

Aren't the standard ones that size?

Umm yes... Thats why I said "Yellow are Unisia JECS 444cc standard injectors".

 

[kismetcapitan]

unless they're Nismos, in which case they would be 550cc. Are they marked somewhere with who made them?

Side of the injector - tiny symbol recessed - it will say UJ. Unisia JECS. Failing that if they are an early set they may just say JECS on the side.

you wouldn't happen to know how Nismo injectors are marked, would you?

No idea to be honest - bear in mind that Nismo dont actually make them, they will be either JECS or Denso branded I would think.
