hello ! i whant to know what is the best to go on my ralliart 2006 turbo ! i need 550 cc injector what did fit bold on PLZ !

STI ?
EVO 8 ?
WRX ?


Thanks a lots

 

Search... this has been discussed.
I think the WRX injectors fit, not 100% sure though..

 

i shearch but i dont find it :S ! but you don't talk if the injector of the evo8 fit on it :S i need 550c the wrx it not that big !

 

evo injectors fit i have a set of 4 if u need them shootme a pm

 

Erm, I don't know where you heard that. I'm pretty sure Evo injectors are the wrong impedence.

 

^yeah something like that

you need side inectors with high impedance,
WRX light blue 440cc injctors will work fine,
i dont know why u need 550cc unless ur doing like 15psi +
rpw had christines(chowetime) running 7-10psi on ~400cc with stock fuel rail

ps, there are a million threads about this already, i know coz i started like 3 of them

 

yeah, search some more. also, the information you are asking is very basic, have you not done the proper research on injectors?

 

ive heard the wrx injectors work.

 

found this, but pics are dead... maybe it will help a little:

Injectors 101
ALRIGHT@@!!! now I am happy IM is DONE here are the pics before I pack it and send it to PR. This is also a how to install the WRX blue injectors.

Here to the left Ra injectors 305 cc ?(green) right WRX 440cc (light blue)



If your powers of observation are still working you wil notice WRX injectors are taller.. and you can see also my kitchen
If you want to change them you must use the oring from the RA injector (the top orange oring in this next pic)



if you fail to do this the injectors will probably leak..

Next a pic of the connectors exactly the same!!!..




Now the hard part.. The WRX injectors are taller and that means you fuel rail will need some modification..You first need two longer bolts the same thread patter of the stock but larger. Then what I did was purchase a nut and washer kit and installed those between the manifold bolt surface and the fuel rail surface in order to level it.. IF YOU DONT DO THIS YOU WILL CONTINUE TO TIGHTEN UP THE BOLTS AND EVENTUALLY YOU WILL DAMAGE THE TOP RUBBER SEALS THE WRX COME WITH
Just put enought washers or nuts and leave like 1/8" free to tighten .....

HERE IS THE END RESULT



more angles



the EGR installed with the bottom EGR blockoff plate







I need to thank DREW for providing me with the stock fuel rail and injectors and a EGR valve.... hes been a great friend and support for this project....
