Just read threw all this injector stuff as my wifes legwag 90 manual finally had an injector prob, knowing nothing about it, except they are kinda pricey went to the yard pulled the right side fuel rail with both injectors red tops off a 94 auto, installed the whole piece and it fired right up idles smooth as it should runs as it should, to soon for mileage numbers but no ECU swap and it looks as if its good to go, Subaru legos are plug and play............G

I just got through reading this thread and I am not sure but what years of injectors are compatible (there is a lot of info in this thread hard to absorb it all)
It sounds like 90-94 2.2 is compatible auto or Manuel. What other years are compatible for the 2.2
I have a full set of red top auto injectors out of a 95 impreza and would like to know what they will fit in without ecu swap
Btw good thread you guys should make this a sticky

I know this is like beating a dead horse, but in the beginning of this post, it was stated that I could simply swap the injectors and rails (red top) and go. But later, it says that I need the ECU as well. I have only found the red tops in MT cars, and on a Ford, at least, you absolutely cannot swap a MT ECU into an AT car. The idle speed tables and timing tables are completely different between the two.

   Please clarify this for me, as Ive found dozens of red top injectors and rails, but NON of these cars still have an automatic. Thanks!!

Injectors don't care what ECU they're hooked to. They all run on 12V. If they plug in and fit in the rails they'll work.
I've swapped red to grey and back again in two different cars (one auto, one manual) not a bit of difference as far as I could tell.
