hey i have a completely stock 91 legacy turbo i think i have a bad injector and am upgrading everything anyways so i bought some wrx blue 440s can i jus put them in or will i run rich?

They won't fit the stock fuel rails and no you can't just put them in without a tuning solution. The ECU was carefully programmed to use the injectors it currently has. And in any case you don't need more fuel unless you are increasing air (boost).... And for that you will also need a tuning solution.

ok what rails do i need?

WRX rails, preferably the year you got the injectors from.

You best bet for info for the early turbo Legacy's is over at http://bbs.legacycentral.org/

thank you ill check that out but i did find a nice pair from a dohc ej25 that i had in my piles of parts

DOHC fuel rails won't bolt to the EJ22 intake......not directly.

 

the mounting bolt holes are spaced differently, and the tabs are on opposite sides. (2.2 tabs go out, 2.5, tabs go in)
