jakeoster Posted July 23, 2010 Share Posted July 23, 2010 (edited) Now I don't know if this is just a rumor or something, but I have heard that EJ257 injectors for a 2005? Subaru Impreza Sti (usdm only I believe) are a direct drop in replacement for the RB25. Apparently they are 444cc sidefed injectors and they can be had cheaply. All this seems too good to be true, are these facts? Edited July 23, 2010 by jakeoster Quote Link to comment Share on other sites More sharing options...
RS Speed Posted July 24, 2010 Share Posted July 24, 2010 The sidefeed yellowtop injectors from a USDM subaru STI are a direct plug in other than the injector clip which needs to be modified to fit. They were flow tested at 525cc and they fit the sr20, ka and RB side feed rails perfectly. I've personally ran them on every one of those motors lol.

mtnickel Posted August 18, 2010 Share Posted August 18, 2010 Side note: I bought 3 sets of these (3 sets of 4 = 12), so I have 2 6 cyl sets for us RB guys. I figured better to buy an extra set than have 2 spare injectors. Anyways, if you haven't bought them yet and want them, let me know. I found injector clips off some subaru at the Junk yard. Think I only got enough for me. But they were easy enough to find. Let me know. Mark Quote Link to comment Share on other sites More sharing options...
