Hi there! I was wondering if you could mod the stock legacy turbo injectors to flow MORE! I have read many wrx owners have done this and pushed there stock injectors over 600cc!!!

All they did was dremel the tips off them to do this!

Is this true? Can i do this to a 93 legy turbo.

Actually, you can.

But not the turbo pinks....

Take the 270cc RED injectors and grind/cut/whatever the flat tip with the tiny holes in them and presto, 500-550 injectors.

Just get them flowtested.

Doug....you need to chill on the post button.

Yeah you can't mod the stock turbo legacy injectors, which I said no.

Really? That's great,I have two sets of those red injectors sitting around.

You're going pay at least $35 per injector to have them flow bench tested. For $140 you are damn close to just purchasing stock '04-'06 STi Yellow 550cc injectors. I only paid $150 for mine from a local college student with high hp dreams.

No cheap ways to get hp huh?

I just posted in the Parts Shed a link to STi Yellow injectors on eBay that currently sit at $75 w/ no bids from a full car part-out.

these 270cc RED injectors come from what car?? Because if i can score some of them i could run a vf39! But..

would these 270cc moded injectors run on a stock leggy turbo computer???

If so COOL!

EJ25D and EJ251 motors have the red body injectors.

Post by **Legacy777** » Thu Sep 18, 2008 2:55 am

The red injectors come from the 92-94 n/a legacies.

The ej25 injectors are top feed and won't work.

EJ25D injectors are the same as the '92-94 NA injectors. My SR20 injectors are a direct swap over to the rails on my EJ25D heads. Otherwise I'd bee looking at some Outfront rails.

Ok, good to know.

Coool! now they dont run in the stock leggy turbo fuel rail, but will the computer beable to run them??

dropdfocus · Post by **dropdfocus** » Thu Sep 18, 2008 4:31 am

Correct, ALL the Subaru "Red" injectors are side feed, not top feed.

Anybody have a pic of modded red injectors? I've done plenty of the WRX top feeds but the caps on these are different.

Tommio RS · Post by **Tommio RS** » Fri Sep 19, 2008 11:19 pm

Yes i second these picture of the moded red injectors!

Does anyone know if these injectors run on the stock leggy turbo ecu???

dropdfocus · Post by **dropdfocus** » Fri Sep 19, 2008 11:56 pm

They'll run on the stock ECU, but having some sort of piggy-back FMU is heavily suggested.

Cool. Thanks very very much!!!

Depending on the actual modded flow rate, I can't imagine the factory ECU controlling all that extra fuel with any authority. That's got to be 35-40% additional fueling from what the ECU expects. Even if the fuel trims could compensate in CL, which they most likely can't, the OL fueling would be horrific. I wouldn't waste your time trying this.

Now if you were to through on a piggyback, then you would be just fine. The eManage would be able to do it as well as others.

The TurboXS Dtec fuel controller is rather inexpensive as far as options go.

Tommio RS · Post by **Tommio RS** » Wed Sep 24, 2008 11:08 pm

Ok then. I need a seperate fuel management system. So then really this mod is all most useless... And seeing that i could get some sti injectors and run the same fuel management system and probably mod those injectors whats the point really!!

Thanks for all your help people!!
