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!!

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.

I ran across a problem on the Facebook side of the USMB.
Short story the ecu in their 94 legacy was bad and causing a no start. I sent them a 1990 legacy ecu and the car would start, but would not run right. In short we found that the redtop injectors are slightly bigger and require slightly different flow rates than the gray, black tops.
So to run redtops and get the best out of them you should swap to a plastic MAF sensor and ecu out of a 92-94 legacy that originally had redtop injectors.

My 86 ej22 swapped hatch has a 90 legacy harness with the 90 maf, 91 non blink code ecm, 99 ej25 red top injectors, runs great. I started out with a 90 ecm and grey tops but i had one go out so i swapped over to red tops off a 91(plastic injector nozzels). Ran great for quite awhile then the ecm said it needed a iac and ran on 3 cylinders at idle. I ended up replacing the ecm with the 91 after fooling around with the iac. Again ran great for quite awhile then a red top failed which i replaced with one ej25 red top(long stainless injector nozzel). Kept driving it like that until i put in a rebuilt ej22 and just used the ej25 red tops which are still going strong.
