Finally had a chance to complete my installation this afternoon. Upon starting up the engine, I noticed CEL was blinking... I found out that it was due to blue and green connectors I used to reflash the ECU (Cobb AP stage 2.5 base map).

Car idles beautifully at around 750-800rpm. I checked twice for any leaks in the o-ring area. I did not see any.

Great write up,but when I did my upgrade I didn't remove the breather cover on the driver side and didn't put back the GBOD on the driverside too.I just cut the pipe off the bracket.Still this has to be the best write on this install.I wish it was around when I did my upgrade.

I thought it was a lot easier to remove the breather cover on driver's side to remove GBOD. It only took me ~5 min to remove the cover so it wasn't too bad. I was thinking about cutting the pipe off the bracket, but thought it was easier to put GBOD back on. There must be a reason why Subaru placed a bracket there.

wow they really put those injectors in a pita area to get to didn't they? Thanks for the pics. At least I know where things are at now.

One last piece of advice is that you make sure new injectors are pushed up completely against fuel rail until you feel 'click'. Many people fail to install them correctly and end up taking things apart again. Do not put everything back unless you visually check for any injector leaks. On manifold side, there are no O-rings like fuel rail side, but there are rubber grommets that injectors sit on. You will find that rubber grommet is covered with dust and debris. Using a Q-tip, carefully remove dust and debris.

PS: some people have reported of having successfully installed injectors without feeling "click".

Dumb question....but should you unplug the fuel pump relay before doing this just to be safe or is this not necessary?? I will be doing the install this weekend and wnat to make sure everything is done properly...

IIRC, I don't think it was necessary when I did it on my Prelude, but I just want to double-check..Thanks

You will have to leave passenger's side bracket on unless you cut off a piping that's attached to the bracket. I left driver's side bracket off...

I think it's more of safety issue to have brackets on in case of an accident.

dudical26, thanks for the kind words.

To those who are considering doing thid mod, injector install may sound intimidating, but once you get started, there aren't many things you can screw up on if you have a nice set of tool.

i was honestly suprised with myself, so far i don't have any leaks...just be careful and lube both sides of the injector and the bushing you drop into the injector housing.

same, I just did this install and it went smoothly but very time consuming. I would rather take 2 extra hours than have to tear everything down to fix a leak.

some notes:

I used different o-rings from McMaster Carr, I read about them on NASIOC somewhere. 7mm rather than stock 8mm which allows for less chance of ripping but the same sealing properties. I lubed the 2 thick rubber isolators in motor oil and the 7mm top o-ring in gas.

didn't depressurize the fuel system. shut car off, and spent most of the time removing dp and turbo, by the time we got to the injectors the fp must have bled off because hardly any gas escaped.

car starts very quickly with these new injectors. doesn't hardly need to turn over once before firing up.

Amazing write up.

I'm about to do the reverse install myself (remove pinks/turbo).

Any tips on where to get proper O-rings? I doubt I can safely reuse the ones that are currently in the car...right? I'm in the process of searching but thought I'd ask anyway.

I've got a ton of o-rings left over. If you want, I'll toss 4 of them in an envelope and mail them to you. PM me if you want to go this route.

In semi-related news, I got 290 miles out of 13.4 gallons on my 1st tank with the pinks, which is right in line with my stage II setup.

I've heard of Suby dealers charging $10-15 for one o-ring!

So thanks to this wonderful thread and the confidence it gave me (I'm a pansy) I finished the install yesterday...with no apparent problems, took about 4 hours working slowly and alone.

I did reuse the o-rings that were on the car, I just oiled 'em up and they seemed to seal fine, but I'll keep an eye on them. Also I didn't reinstall the GBOD, mainly to make sure the injectors didn't leak, and now there is no way in hell I'm putting them back in.

Today I did the turbo and exhaust and everything came out excellent...except for wicked WD40 smoke when I was done!

Great thread...one of the classics. Should be reposted at scoobymods because they don't have crap for 02-03 injectors over there.
