wrx injectors flows as good as sti, or even slightly better. You don't need upgraded them if you are adding vf43...

i don't believe there are any details on the vf48 except that it's larger than the vf39/43. you're going to be paying a lot more for a vf48 since it's a new turbo on a brand new car. go with the 43 and be happy with 300/300

I have been told that Yes the 565cc injectors that come with the stock 07 wrx will do the job but a larger injector will enable you to have alot more head room and the ability to realy push either turbo with safty .the same people have told me they have experienced and have seen that sometimes the 565 injectors have restricted the tune by maxing them out .I know that there isnt that much info on the 48 yet but I figured some one knew something even if its vague
