injector options....

[Ej22TIM]

I am wondering what my opitons are as far as injectors go, I have a 22t with 20g heads and intake, I know the stock injectors are 440cc would wrx injectors fit? sti?

WRX injectors won't fit...as they are topfeed...

The stock injectors are not 440s, they are 370s. The 440s are stock on EJ20G, and are grey, the 370s are pink. The yellow STi sidefeeds will fit, and are 550cc, but you will need a piggyback to scale the fuel back.

Do some searching, you will find a lot of info.

I believe you can install USDM STI side feeds in phase 1 EJ25 DOHC fuel rails. I'm still researching this combo, so I'm not 100% sure yet.

I've got a '98 2.5 RS intake manifold in the storage shed I can pull out and test fit the fuel rails on the EJ20G manifold. What I don't have yet is STI injectors to test in the rails.

I've also seen adaptors that supposedly let you install Those particular injectors in EJ20G fuel rails directly.

You need 92-94 n/a fuel rails to use the yellow sti injectors.

I don't think those rails will fit on the EJ20G intake manifold, though, will they?

[Legacy777]

Don't know.....?

[vrg3]

Actually, I think the rails you might need are the ones from a Phase 1 EJ25.

[Ej22TIM]

I will check into the phase 1 2.5l stuff.

and 555bcturbo, I already have the stock 440cc grey injectors, they come stock in the ej20g manifold.

The SOHC rails are shorter than DOHC rails so they will not work on a DOHC intake manifold.

The Phase 1 DOHC rails use the same injectors as the N/A 92-94 rails. As far as fitting on the 20g manifold, no clue. You'll have to get some and compare. SR20 injectors FTW! You can get them up to 1000cc.
