Yes...water/meth injection for the knock supression and intake temp fixer-uper. I built a homebrew kit for about $75.

It's an old thread from a few years ago but the information is solid.

Re: Yeah, its gonna fit....and make 22 plus psi
 

Well, it worked...kinda....Tuning it was going to be a bitch, so I decided just to eliminate it.....

So instead I have started yanking the 550 cc injectors and am grinding off the tips to open them up to be 820s or so....

I will still have some huge tuning issues, but it should be enough fuel haha.

The hardest part will probably be the idle.... The stock ecu expects 270 cc injectors!!!!!!

Re: Yeah, its gonna fit....and make 22 plus psi
 

Modded the rest of the STI 550cc injectors this morning....

Lets just say I have more than enough fuel now.....

Runs fine, maybe not dandy...... But I am happy!

They are now equivilent to 800-820 injectors, plus the 3-1 rrfpr, so I am pulling ALOT of MAF signal up top....

Still tuning, but its fast.

wow, your car is awesome. This is some kick ass ----

Re: Yeah, its gonna fit....and make 22 plus psi
 

i want to see it when its done. what did you do to mod the injectors? can other injectors be modded the same way?

Re: Yeah, its gonna fit....and make 22 plus psi
 

i second this

Re: Yeah, its gonna fit....and make 22 plus psi
 

Hmmm modding the injectors that way, there will be differences from one injector flow to the other=very bad.
I guess he's going for the obese pig-rich technique... otherwise, big risk og going kaboom...
Too bad it aint got a Honda ecu

Re: Yeah, its gonna fit....and make 22 plus psi
 

Nope, he's just removing the last restrictor plate from the injector tips. The next one in line is still the same size as in all the other injectors.

FYI, regular WRX injectors can be taken to 720 or 780, I forget. ;)

Re: Yeah, its gonna fit....and make 22 plus psi
 

aaaaaand can these be run in hondas? that would be a very cheap easy solution to buying $250 injectors

Re: Yeah, its gonna fit....and make 22 plus psi
 

subaru uses two types of injectors....

Side feed (which are also often swappable with SRd20 Nissan injectors)

and top feed

BOTH are modifiable......

I don't know how to modify the topfeeds, but its similar to the side feeds. Here is the link to how to do the top feeds.

I will take some pictures of what I did to my side feeds when I remember to bring the camera to work.
