I have a few friends with WRX's, and they've upgraded to Stg 4, so they replaced the OEM injectors, which are 440cc. Has anyone used WRX injectors in their cars? How well do they fit?

 

best thing to do is just do an eye measurement. take one and compare it to your stockers

only thing you might have to do is bore out the seals a little like you have to do with the 450s

if you get them to work let us know

 

 

wrx injectors are side feed. you'd need to either make or find a sidefeed rail that will work for your car.

 

hmmm sidefeed? how does that work and how is that better or worse? that term is new to me

 

Me too I hear about it but never knew what it meant. I guess I could google it but I'm lazy. :P

 

lazy asses :P

Interesting...learn something new every day.

 

looks like subura used both side feed and top feed injectors.
us sti 2004+ uses side feed.

classics are side feed
and buggies are top feed

need to do some more research.
