So do I take off the stock rubber isolators on the spray side from the stock injectors and then put them on the pinks?

Also, I bought some used injectors off ebay and one of them has two little dents on the circumference of the spray side. Should I be worried? They are only on the circumference and do not affect the spray pattern at all.

pop out the injectors from the rail (thin rubber o-rings hold injectors in rails).

the isolators are thick rubber, I used motor oil. new o-rings lubed in gas, pop them into the rail first. second, lower the rail and injectors into the holes in the manifold. secure the lines/rails to the manifold with 3 bolts.

Wow awesome thread. Thank you OP for setting this up for the subbie community. I had asked a while back for a writeup like this but didn't get any results. It does look a bit complex though, maybe If I upgrade at some point I'll try it but there's a lot of steps and little peices. The only problem I run into on these cars is stuck bolts..if it weren't for those things would go smoothly.

the rubber isolators should come with your new injectors, all you need are new o-rings which should come with your injectors too, if they are used, you probably don't want to re-use them. make sure to put a little bit of oil or vaseline on them so you don't break the gasket.

where exactly are the dents? on the nozzles?

I'm talking about the rubber isolators on the spray side. The dents are on the edges of the nozzle, but don't affect the shape of the spray pattern.

the dents are fine. You can re-use the isolators, it's not rocket science. The isolators seal the top and bottom of the injector body. The thin o-ring seals the top-feed to the INNER fuel rail.

On the ej20 STI pink injector install, is there an additional o ring that sits between the insulator and the engine? If there is, where does it sit and how should I install it? When I pulled out the stock WRX injectors, only an insulator came out.

No, there is the insolator on the bottom. On the top you have another insolator and the o ring.
FYI, on my 04 Wagon on the Drivers side I only unbolted the four bolts on the bracket, I disconnected the ground wire on the top of the injection manifold and I wiggled the bracket off.
I did not remove the IC, battery or nothing else. There is a hose connected to the bracket, I just took off the clamps and hoses. It took me 30 minutes to change the drivers side and 45 minutes for the Pax side.
Also I did remove the winshield fluid tank. Thats it.

Ensure you have new O-Rings, mine is an 04 and when I tried to use the old o-rings they leaked.
To check for leaks you do not have to start the car, just turn the key on. You will be able to see it if it is leaking.
I did not intend to replace the big brackets, if you intend to put the big brackets back on you will have to remove everything that the instructions tell you.

I think it's more of safety issue to have brackets on in case of an accident.
Don't you mean leave the Passenger side bracket off and put the Driver's side bracket on?

No, leave passenger side bracket on if you choose not to cut off a pipe attached to the bracket.

I cut the pipe off the drivers side and left both of the brackets off, makes it easier to get to if I ever need to.
Takes only a few minutes to remove the injectors now.

Yes there is, on my 04 Wagon. It connects to the two chamber tubes that runs along the front of the IC.

Dont know about the earlier modles, but the 04's have it on the drivers side, unless you have a JDM car, then it would be on the pax side.

So I can leave the passenger side GBOD off with no modification...and if I want to leave the driver side off, i'll have to cut the tube off?

yep, I left the passenger side off. Retained driver's side, it was super easy to get back in, and I didnt want to cut off the tube.

Its a lot easier to cut off the tube then to fight with the bracket and have to remove everything toget it out and in. Took 5 seconds with the dremel to cut it off.
The passenger side only holds a couple items on and everything just unbolts from it. The drivers side has the tube which is welded to it so you must cut it off only if you do not intend to retain the bracket after the install.
All in all it's your choice. Once you fight with the Pax side to get it off, and get to the drivers side you will understand why I chose to remove it for good.
Good luck.

Well, it took me about 3 min to put driver's side bracket on. I think it looks better with the bracket on. I never put passenger's side bracket back on.

I dunno, maybe the instructions I had were dorked up, but it had me taking so much crap off the driver side, and when I seen the 4 bolts holding it on and took me a few minuteds to wriggle it out, I made the cmd decision to just cut it off. I didnt take everything off that the directions told me too.
Great for the guys who were able to do it. I think the engine compartment lloks cleaner without both of them. IMO

i left the driver's side bracket off, but put hte passengers side on because there's a lot of things that mount to it. i found the brackets really weren't that hard to install/take off anyway.

What did you guys do about the ac lines on the passenger side? They attached to GBODs, but now that I took it off, do I leave it dangling?
