550 injectors or maybe 640's
 

i am after a set of injectors to fit my98 sti 4
i am unsure which ones they are tho! phase 1 or 2 so if anyone knows and would like to tell me i would appreiciate it!
the coilpack is central

Phase 2 is V5/6 where the Coilpack is on the RHS of the inlet manifold :thumb:

so would i be after phase 1 injectors?
or is there such a thing as a 1.5?

is there such a thing as phase 1.5?

Yes mate, a version 4 would be phase 1.5
