Question What is involved in installing STi injectors?

I am looking to add the Cobb VF34 upgrade to my '02 WRX and I think I can figure everything out, but I am curious if there is anything difficult or unusual about installing new injectors since this is one of the few things that I have not had to do in the past.
Thanks

Patience and about 2 to 3 hours. The '02s have green brackets that cover the injectors and fuel rails, you have to remove these and it takes a bit of finesse. They are named the "green brackets of death". Do a search you will come up with several hits with tips.

I understand you are using a different vendor, but the TurboXS Stage 4 instructions might prove helpful.

Disconnect the fuel pump relay located in the passenger footwell. Run the car till it stalls and then crank it for a few seconds to remove as much of the latent fuel pressure as possible. For removing the GBODs, I strongly recommend having a 12mm gear wrench (mine is offset, straight one should work fine too). It is possible to remove the brackets without unplugging the TGV sensors, which is worthwhile since those sensors are spring-loaded and can't simply be plugged back in as-is. Everything else should be fairly self explanatory after looking at it for a bit--i.e., what to unbolt to give yourself more room, getting the rails disconnected from the head, and so on. If you end up leaving the brackets off (they would be a PITA to put back on, if you ask me), either cut off the ventilation system hard line on the rear of the driver side bracket, or go to the hardware store and find a method of connecting the hoses together.

The green brackets of death eh? Maybe this will be one mod that I will finally leave to the pros. Maybe I am getting old.

I did this myself, and calling me a "pro" would require certifiable insanity. It is much, much easier than it sounds and/or looks.

The technical skill required for this mod is not that great... It is the whole patience is a virtue thing that your mom taught you that will be tested. Green brackets of death are the DEVIL... not at much as the uppipe devil but almost as bad, hehe.

Good Luck,
RJ

Well,
I guess it's worth a shot. I will test out my patience as long as there is a wall near by for me to throw things at when I lose my patience.

I suggest you start with the drivers side first since it is very straight forward. Less "death" involved on this side.

Now go have a drink and tell your self how easy that was and that these "internet" guys don't know what they are talking about.

Ok, now plan on it taking 3 times as long on the other side. It is much easier to do this side with the turbocharger and intercooler removed. From memory...you may need a crow foot and a swivel joint.

Don't forget to "clock" the injectors properly and make sure you do not accidentally pull the fuel pressure regulator boost source line.

Good luck!
Phil

Thanks for the advice guys. Very funny, indeed. I will be sure to bring some single malt scotch to work the day I attempt this to make the passenger side go in easier. ha

Hmm, scotch... now you want to be able to get to the other side. Ah well, just make a small drink. Dont wanna fall asleep between the two sides and have half of the injectors done, haha.

Between the gas fumes and the scotch, I would give yourself 10 hours

Thanks,
