How big of fuel injectors should I get for my 7afe. I'm going to boost it around 10 psi trying to make around 200hp. Thanks guys

315cc are near their peak for ~220hp i believe...

Any suggested injectors?

If you're getting 315cc, 7m-ge supra injectors are high impedance and are 315cc.

They are the ones with the lime green top if I'm not mistaken.

Thanks!

Stock ST205 has 245HP and is running on 540cc injectors. I know they handle safety 300HP without raising fuel pressure (so there is some space for upgrades). So engine with 22% HP more than you want has 540cc... If you lower 540cc for 22% you get 420cc. But that is just mathematic.
On my old ST-T I had installed 330cc injectors (from Ford Probe I believe) and was running 206HP. I had no issues and running it like two years. Anyway... What I know is it was not safe at all because those 330cc were running on 100% of duty cycle (to give enough fuel to those 200HP) when pushing it. Now If I had to run 200HP car and would want to be safe for 100% they are running max at 80% of duty cycle. And again using mathematics I'm somewhere around 400cc.

So from two different points of view I got into range 400-420cc. How much you believe in my mathematics is up to you .

^^^ those are also low impedance injectors, you will need a resistor pack. just get the NA 7M-GE injectors. they are a drop in and work.
