October 30, 200916 yr Read thru all these build threads, lots of info on injectors. http://forums.nasioc.com/forums/search.php?searchid=9439317
October 30, 200916 yr Hhhhmm - for some reason you link to the NASIOC search doesn't work Rob. Here's what I know from my research. Subaru changed the injector style on their Turbo's to a style similar to that of the non-turbo's durring the time that we didn't get any of their turbo engines for the US market. So that the old EJ22T injectors are different than the newer EJ20T and EJ25T injectors that are on the WRX/STi and other turbo models. That means that in order to interchange the injectors from the newer turbo's to the EJ22T, you have to change the fuel rail. What you need is the NON-Turbo fuel rail from a 93 or 94 EJ22. These will allow you to install newer turbo injectors on the EJ22T and will bolt up to the fuel system of the EJ22T. Just get a used set from the junk yard or ask if anyone has a set over on www.legacycentral.org. If you aren't making any modifications to the engine, try to stick with injectors that are rated at about the same CC's or you will have to change them all, and change the fuel pressure to match which is going to make it more difficult than just a simple parts swap - it would have to be tuned with probably at least a wideband. The other option is to get a used set of 22T injectors and have them rebuilt and flow-tested. A wise investment if you don't plan to otherwise mod the car. GD
October 31, 200916 yr Stock 22T is 370cc IIRC. The stock ecu will run 440's but not very well (pig rich @ idle....) plus if you need the 440's you will eventually need a different MAF as well, my stock MAF (aluminum hitachi) maxed out at 12psi on a tdo4 which means fuel dump (injectors go static... 100% duty cycle). If you are going to slightly modify your car, I would look into a revtronix's chip and get a plastic jecs MAF off an n/a car. With the chip you can get whatever compatible side feed injector's you want and they will program the chip to run them. You can usually get a set of jdm 440's for about $200 on ebay, stock 370's are usually a little less $150 or so. Scott
