Hi , as the title want to find out what injectors i have , i bought them for my 95 wrx , i was told they are 550cc , but not sure , cheers

part no. 0r55 a4655

 

Might be 550's mate but the ones that have seen are all pink in the 550c, cant say i have seen red ones before but one of the lads will soon set you straight am sure lol.

 

Whatever size they turn out to be (and I suspect they are 550s), the one on the far left is scrap as it is missing the nozzle spray cap and would cause a misfire if fitted.

 

Pintle caps can be replaced. Looking at the condition of them i would certainly get them serviced i.e. flowed and checked.

Speak to Mark at http://www.lateralperformance.com/

 

thanks for reply's , so can i get a new nossle spray cap or can't these been replaced ?

 

Posted at the same time, please see above contact.

 

, cheers , will get in contact about getting them flow tested /refurbed ,

 

another question i am only aiming for around 330-350 bhp from my classic and have some yellow 440cc and fuel pressure regualtor aswell , would these make that power, if it turnes out these injectors are not 550cc and not worth fixing , cheers

 

440cc should see you hit that mark with suporting mods but they will be maxed out the 550cc in the picture look like nismos to me but i could be wrong and they do need refurbing

 

thes say JECS on them if it helps , and i was told they were form a legacy, cheers

 

If they're legacy specials then these may just be standard, especially if they Got JECS on them hmmm...

Me personally if thats all the power you want then i would suggest you put the yellow 400's in. But i would definitely spend a little money on an after market regulator. You will see multiple reasons for replacing the fuel reg on these forums.

Good Luck

 

so the 440's should be ok then, i already have a sard fuel pressure regualtor on the car so no problem there , . and going to get them cleaned/flow tested before i use them any way , cheers

 

You will be fine with 440's for those power levels. Stick to the yellows for the time being i would say. As i'm sure those red injectors will be no better.

If you plan on further modifications in the future then obviously the 550's will give you more headroom.

Good Luck

 

just to add to this thread, these injectors may not be 550cc.

they could be the 280cc from the legacy 2.5???
i'm after a set of 550cc injectors, and due to this thread looked for the red ones, if jecs then more than likly they are the 280cc ones

ej25 injectors vs/ej22 injectors [Archive] - NASIOC
off another forum. good info on these red injectors
just throught id add my say

 

^^ i think your right mate , they are the 280cc form the legacy 2.5 as the part number matches up , so smaller then my 380's i have now , ebay seller keeps trying to say they 550's but i only paid £20 for them so not too botherd,
still don't know whefer to run the 440cc's yellow injectors, and be right on the limit or buy some 550's so i know they are not going to hold the car back ,
does any one know where i can get some 550cc's from for a good price , cheers

 

i'm running 440cc one at the mo. im after 330/340 bhp
been told that 440cc injectors will be more maxed so better to fit 550cc one & get it mapped

sard do the red ones with 550cc.
but the jecs are standard for scoobs and seem to be 280cc
i'm yet to find out what colour the 550cc one are
