they are "pintle" style injectors

now, from what i hear in the DSM world, they are interchangeable.....

but i really dont know. i mean, its just a needle valve versus a ball

civic2scooby · 03-10-2007, 12:22 AM

just found out they dont interchange....but that link I posted on ebay will I talked to the seller...gonna do 660 injectors as per my tuner.

Jaxx · 03-10-2007, 09:38 AM

its the shape of the rail thats the proublem

the only reservation i have is that the "venom" injectors don't have an espically good reputation

The STI side feeds fit into the JDM/EUDM 1999-2000 fuel rails, and also the EUDM/USDM Legacy 2.2 and 2.5 up to 1998.

snowman4us · 03-10-2007, 12:49 PM

Im running USDM STi inj. w/ ej25(NA, dohc) fuel rails. it was a good upgread and cost less then $200. If you looking at 300WHP this settup w/ be perfect. if your looking for more, contact RC and see what they can do for you.

oldhat · 03-10-2007, 09:59 PM

BTW, does anyone have a write up on how to swap injectors in an EJ20G?

GripGC8 · 03-10-2007, 10:14 PM

snowman4us is saying:

you can use dohc 2.5 fuel rails and usdm sti injectors on your ej20g.

Marnix · 03-12-2007, 03:32 AM

Also what I meant but maybe I wrote it down even more confusingly...

yeah, I was just confused on the wording.

turboL · 03-12-2007, 03:37 AM

sent you a pm on how to do this, probably work the same way for the dohc 2.5 rails.

Guys, I know this has probably been beaten to death, but I haven't been able to find a definite answer to the following question...

Are the ANY USDM injectors that will be a direct replacement for a '97 WRX GF8 EJ20G motor (Phase I, grey tops), WITHOUT changing the fuel rails?

Thanks.

Jaxx · 08-25-2008, 02:03 PM

no 12345

Zora · 08-25-2008, 03:54 PM

Thanks for a quick reply. So could I use these fuel rails with STi injectors: http://cgi.ebay.com/ebaymotors/_Car-...4506.m20.l1116

They list a lot of engines, but I read in other threads that it is only the 2.5 DOHC rails that will work without mods. It would be nice if someone could confirm whether these will work for me.

Thanks.

Jaxx · 08-25-2008, 04:46 PM

there are a few thread on this
i used 1.8 rails and had the tabs welded on

the other option is to use collers and the phase 2 injectors
