no not all subaru motors require the same injectors. what motor do you have. if you have a 95 leg with a turbo motor than this is a swap or you bolted on a turbo to an na ej22.

so you have an na ej22 and you have made a turbo kit for it?
I believe those are side feed like the ej22t. or maybe I have misunderstood you and you have a ej22t block.
any ways both motors have to use sidefeed injectors. unless you want to use a different manifold and some other parts.
the ej25 sti motor used side feed. I am pretty sure those will work. but I haven'y tried them myself.
ver. 3 sti ej20's were sidefeed. so you can get those they are 440's. so a bit of an upgrade from the ej22t's 370's. but not much.
what I am getting for my ej22t are nismo injectors for and sr20det. they are around $500 for 550's or 740's. so probabally the answer to your question is no. 550 sti injectors for a version 4-7 sti are topfeed.
if that doesn't answer your question I am sorrie but I would need to understand your motor setup a little better.

i believe that you will have to look into jdm nissan injectors for this engine. i built my 93 2.2l na engine and the only larger injectors i could find were from a nissan. do a search on jdm silvia injectors and this should yeild some good info.

kelley, i believe sr20det injectors are not the same as the turbo legacy injector. the turbo legacy injector is fatter with the same size o ring top and bottom. wheras the n/a injector is smaller at the bottom than the top

edit check these posts out, they should help. pm me if you need more help.
