I have a MY94 wrx import wagon. I need to know what my standard injectors are. What direction do they spray? The reason i ask is i want to upgrade them to sti ones and not sure what ones i need. I hope someone can enlighted me and help me on my way to bigger bhp.

Cheers
Iain

Cheers pete. So i will need 440/550 side feeds then?

 

depend on what bhp your going for think 440cc are good for 300ish maybe a bit more

 

Aiming for 300. Already have fuel pump upgrade, turo upgrade to VF34, full decat, green fillter so just need injectors and top mount intercoller now.

 

If just aiming for 300bhp , 380cc will do it mine ran fine for 8 years others have been fine too , if running lean you could fit a fpr and up the pressure .If over 300bhp then yes upgrade .
