2G Injectors low vs high impedance?

1999 Eclipse GST

Good morning I'm confused over getting my injectors? I'm between FIC 1220cc low z or FIC 1200cc high z. I currently running a Walbro 380 rewired, and a big 16g turbo.

I'm planing to tune the black box but don't know what injectors to get plz help

Are you planning on a bigger turbo in the future? A set of 1200cc injectors is overkill for a 16G - you would be fine with a set of low-Z 850s with the stock resistor pack in place.

Im planing to stay with the 16g but trying to run 20-25 psi
And probably going e85

The 4G63 takes low impedance injectors from the factor but does this by running a large resistor in series with the injector. One can keep the factory setup and install low impedance injectors, or one can get high impedance injectors and either modify the resistor pack or buy a plug. I went with the latter and have 1000cc high impedance injectors fueling my 16g setup. With high impedance injectors, there isn't a downside to having a large injector size like that.

For around the 1000cc mark I have never had any issues tuning low impedance injectors. Normally if going larger then say 1250cc is where the big benefit is. My 2150cc idle and cruise like injectors half there size.

@randman2011 I am about to install fic 1000cc injectors to my 16g, fmic, etc. Though I know each individual build varies dramatically, I am curious what kind of power you were making with those. Thanks

I got the 1220c low z, they were a good easy install and easy to configure using ECMLink

I’d recommend em

What did you do for yours because I've been having issues with the tuning side of mine for getting em to work, shits misfiring like a mf no matter what I do

What do you mean?

Do you got ECMLink?

You just open up and adjust the fuel injector size & a couple other things

then do this too to InjBatteryAdj and save settings, then the car should start
