Well several things factor in when deciding to go with injectors. Most importantly though, what's your power goals? If you achieve those goals, do you think you'd want more power? Not sure about good mileage bud, you're a** out on that lol. Personally, I'm going with Injector Dynamics though. I've heard great things about other injectors as well though. FIC, PTE, and etc. Pick your poison.

well what size injectors come stock in the Evo?

Your power goals would be helpful. You can still get decent gas mileage if not better than stock with a proper tune. Stock evo injectors are 560cc IIRC but in Evoscan it reads 513cc.

I'd like to hit anywhere from 300 to 350

I'm shooting for the same power goals as you and I settled on 880cc injectors. There is a calculation for injector duty cycle and horsepower. You want to be lower than 90% duty cycle to be safe. Give me a sec and i'll send you a link.

if I get 880cc injectors will I still be able to DD my car and drive it in the winter efficiently???

Yes, but you'll need a tune to scale them correctly. You can't just slap them on and expect the car to run correctly. I know guys with 1000cc injectors and bigger and the driveability is unchanged. Tune Tune Tune!!!

Of course!!!! haha thanks for the help…. I think ill go with 880cc injectors

If you are planning on 300-350, I suggest you keep the stock injectors but change the fuel pump. If you decide to run e85 or larger turbo, that is when you need to get bigger injectors.

agreed with evo8426, I am making 325 with a turbo back, ETS intercooler and fuel pump. The tune is everything.
