Guys w/565cc's w/EVO3's

Hey all, been a while since I have posted over here. Got a question and need as much feedback as possible.

I need to know what your injectors are running at (duty cycle) while tuned with an EVO316G. 06-07 WRX guys if possible. Need to know if I NEED to send my stockers in. Thanks all. I appreciate it.

I believe thats going to depend on alot of different variables, you can have another car sitting next to you with the same mods and it could be different also the altitude would have effect of that as well I.E. where other people live and what not, i would just call your tuner or something and see what they would have to say about it.

Umm I'm pretty sure you could easily max out 565's with an evoiii16g, like, 100%dc would not be uncommon. On a 2.0 my idcs were around 70% with that turbo, and I have 860s (my map was rich, though).

Exactly why I'm trying to get a few #'s together. I will determine what I need after all is said and done. Thanks for the help so far.

Well, look at it this way... If COBB runs their 18G map off the stocker 565's.... that's got to be rich as hell. I'm not going to run an all out balls to the wall tune on this.... just need a ballpark on what is ok and what not.

WRX Fuel injector sizing guide STi Fuel injector sizing guide Lgt fuel injector sizing guide, JSC Speed Check out this chart. I would go with either modded or aftermarket ones so there is room for growth or error.

The map will probably also severely limit power. I bet it runs like 13 psi. At MINIMUM you'd want 650cc's (unless you run meth).

Just a question of money and power. It's very cost effective to get your injectors modded if you're already getting that turbo and already planning a custom tune. Course, maybe you're content with whatever power level you can eek out of the stock injectors too.
