Instruction: Pink injector install on 02-03 WRX

txl146 · 03-19-2006, 09:24 PM

Click here for TURBO install

I spent 3 hours today installing pink injectors and removing stock turbo in near freezing weather. It took me 1 1/2 hours trying to unbolt one of 3 10mm bolt holding a breather cover on driver's side, which I later find out is not necessary to remove (optional)!!!

- Pull the ignition fuse (#11) from the fuse box under the steering wheel column. Crank the engine for a few times to relieve fuel pressure in the line.

Hope you find instruction and photos useful.

Tools you need:

wrench, 10, 12, 14mm sockets
plier
zip ties
PB blaster

Remove two 12mm bolts that hold IC

Remove BPV by removing two 12mm bolts (be careful not to lose a gasket)

Remove TB hose

Remove turbo to y-pipe hose

Remove two hoses (driver's side has one hose)

txl146 · 03-19-2006, 09:26 PM

IC removed!

Remove this plastic cover on driver's side

Remove the intake box (there are two bolts - you need a long extension to reach there)

Intake box removed!

txl146 · 03-19-2006, 09:27 PM

Remove the battery

Move a windshield washer reservior (two bolts)

Bracket is visible now!

You will have to take this breather cover off in order to reach a 12mm bolt that hold driver's side GBOD.

Removed!

You can reach from the top to unbolt this hard to reach 10mm bolt on breather cover.

Picture of driver's side GBOD! Took me about 30 min to remove IC and GBOD.
You will have to bend a AC line slightly to create enough room to wriggle out the bracket.

You will have to put this piece back on as hose off of breather cover is connected to a hose on GBOD. You have an option to cut this section off of GBOD and install it back on. I decided to put the bracket back on.

You will have to bend a fuel line slightly in order to remove stock injectors. Be sure to use a gas to lubricate o-rings before installing pink injectors.

Here are two stock injectors:

There are two 12mm bolts holding a fuel rail

Remove this 12mm bolt that's holding a fuel line on left side of injector closest to the front bumper.

Gently lift the fuel rail up with your left hand and use your right hand to pull down the injector to separate it from the fuel rail. Make sure to disconnect the harness from the injector first.

txl146 · 03-19-2006, 09:40 PM

Picture of Pink injectors with o-rings correctly installed:

Make sure to pull up injectors hard toward the fuel rail until you feel 'click'. Please note you may not always feel the click. Don't forget to reconnect the harness to each injector

txl146 · 03-19-2006, 09:45 PM

Now, it's time to tackle driver's side GBOD!!!

txl146 · 03-19-2006, 09:53 PM

Here are pictures of GBOD (CREDIT TO RayfieldsWRX from clubwrx.net).

Remove 5 12mm bolts on bracket as well as a few other bolts.

There are two hard to reach bolts (2 12mm bolts that hold bottom section of GBOD) hidden behind here. There are two options to tackle these two bolts. First option is to remove a breather cover by unbolting 3 10mm bolts or by using a small 12mm wrench to fit behind a breather cover. I went with later option with a good success.

Two bolts that are holding a fuel rail. Remove these (one on left is hard to remove, so wait until you remove bracket first)

This bolt is hard to reach (use a wrench since there isn't enough space to use a socket in there). Picture not shown is another bolt that's located right below this 12mm bolt. Once again, you will have to use a wrench to reach down there. It's one of the most difficult bolt to reach during the install.

Remove a coolant reservior tank:

txl146 · 03-19-2006, 09:57 PM

GBOD REMOVED!!!
You can see blue stock injectors here:

Follow these steps in order to remove and replace injectors.
1. Remove this bolt that holds a fuel line (bolt shown below is facing towards front bumper). Once you remove this bolt, you will be able to lift the fuel rail slightly to be able to remove stock injectors.

Optional: two 12mm bolts that are holding the fuel rail might be difficult to start the thread; one option is to remove FPR which will give you more space to work around it.

2. Once again gently lift the fuel rail with your hand and use your right hand to slowly pull out the injector. Sometimes o-ring may fall out while pulling the injector out. Once injectors are out, install pink injectors.

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?

Goos job man & thanks for the how to.

Hope you enjoy these photos. If you have any question, please let me know.

Dude! I've been looking around for a good thread that actually had pics of the friggin GBODS before I do this myself. This is the best thing I've seen on any board. Props.

Thanks for the kind words. I looked everywhere for the instruction, but I couldn't find any good instruction that are easy to follow. So far, I have two instructions written (STi TMIC and Pink injectors).

Next is turbo install.

Sweet, I could use one of those too. Please make sure and get good pics of banjo pieces. If you're going with a VF turbo, (good bet since you're using pinks) I'm interested to see what is what. I've got a VF39 sitting in my garage waiting to go in but the guy actually left one of the banjo fittings on the top on it and I don't know if I'll have to remove it in favor of the stock piece or if I can just swap hoses.

I should have turbo install instruction ready by tomorrow... problem is that I did not take as many photos as I had wished.

veightkiller · 03-20-2006, 12:24 AM

nice job men thank's for sharing!

wrxtreme2 · 03-20-2006, 02:20 AM

Great write up on the injectors !

specialev · 03-21-2006, 12:42 AM

Nice work man! That's by far one of the nicer sets of instructions I have seen. All thanks to the ton of pics.

neko · 03-21-2006, 01:46 AM

wow.. what a pain. tho i knew it was gonna be.
heck, i loved cleaning the injectors on my new toyota motor i installed a year ago or so. right on top of the throttle bodies, just remove one little plate that holds each pair on, then pull them out.. simple. 20sec max. my sr20det is simple like that too.
wish my wrx was that simple. i guess it would be once the GBOD are gone.

well i've been sitting on my pinks and vf34 all winter, and just got off my butt and ordered the walbro pump yesterday. maybe i'll get around to my install soon. so thanks much for all the pics, i'll put them to good use. since i take it you did a vf34 and pinks, did you do the pump yet? thats the part i'm kinda lost on the method for...

txl146 · 03-21-2006, 01:49 AM

No, I did not do a fuel pump yet because I can run without it on Cobb stage 2.5 map. That's next thing I am going to get since I have ordered a custom PDX map...

neko · 03-21-2006, 01:50 AM

huh?
i thought the cobb stage 2.5 map required it?
am i just wrong? i always thought a vf34 and pinks required more fuel than the stocker could put out?

course, since i have the pump, might as well stick it in, it should be a shortinstall compared to the turbo or inject.
