2005 evo with evo9 turbo.
are the stock injectors good the max turbo limit?
should i just go with one size bigger like 750 to 880?
i believe stock injectors would max out at max boost which would increase duty cycle only if I'm pushing it to the limit, should i just upgrade them for a piece of mind.

by the way same thing apply to fuel pump.

let me know what do you guys think!!!

 

An Evo IX turbo can put out some decent power. In my opinion get a Walbro 255 ($110) with install kit and then some injectors around 1000cc. I personally like my FIC 1050cc injectors ($345), easy to work with. Those two things should hold you over for plenty of power without having to worry, plus its not to much money and very easy to install.

 

what is everyone pushing on eve 9 turbo? PSI?

 

i have fic 750cc for sale. made 394 on stock 9 turbo with walbaro and had room for more. Pm if you want them. they have 5k miles on them

 

That's an extremely broad question with many variables. Go to the dyno tuning section and search evo 9 turbo.

 

I will be pushing 27psi with mine but it all depends on your setup and what kind of power you want to see. I wouldn't push a IX turbo much past 30psi depending on how you drive it daily.

Definitely search this. Plenty of information on here.
