I tried last night to pull out the injectors but it requires all the injectors to come out together and i don't want to pull too much of it apart, but i did notice a "RAM" and "B 6" on all of them if this helps.
They are the marone/dark red coloured tops and are from the holden vl turbo model commodore. They should be at least 450cc each and there are eight so there's plenty of fuel for any four banger, unless your running a t88.
There's lots you can do with this setup like run one set of four at low boost and the other at high boost, nitrious, etc, etc.
