Stock Injector size


Recommended Posts

I was going to but someone advised agaisnt them. He drives a 93 Subaru Wagon with 440WHP. So I am taking his advice on it. He will be helping my assemble the turbo build.

 

So the WRX injectors will fit right in?

Depends on what turbo your using. My stock wrx td04 and 440cc box will max out at 22-23psi. Same injectors would max out on a 18g at 15psi or less.

 

So I have DW 750s if your using anything bigger than a stock td04 you need to use walbro 255 and 565cc or higher injectors ;)

 

This is on an ej205 swap. N/A can do 6-10psi on stock wrx td04 and 440 wrx injectors although I don't know what the stock fuel pump would handle, your gonna need a good tune or don't be pushing your car too hard..

I am going to get the piggyback system and find some place that can tune it.

 

So 440WRX injectors will bolt right in to the stock EJ22?

 

Looking at 6-7PSI on a TD04 turbo yeah.
