2G Recommended size of injector to run with 20G?

[T'd Up Steve]

As far as I know, the newer injector designs are mostly high-Z. And they are better, not necessarily because they are high-Z, but because they are newer designs using the most recent improvements in injector design.
As for how this happened I'm not 100% sure, but I think there was a bit of tail wagging the dog.
Low-Z injectors are suitable for Peak and Hold type injector drivers but not so great on simple basic drivers like we have in our DSM cars. Peak and Hold drivers can put out a lot of energy in the first part of the pulse, which gets the injector moving real quick.
But Peak and Hold drivers are expensive if they are good.
The car OEMs didn't want to have that extra expense in the ecu, or as an add-on either.
A resistor pack is a cheap add-on, and it makes Low-Z injectors usable with ordinary non-fancy injector drivers like what the OEMs wanted to make, like ours. But the injector performance is not very optimized that way.
At some point, the people working on new injector designs said OK screw it, we'll just make the injectors suitable as is for these simple cheap injector drivers that are not Peak and Hold.
And from then on it was so, and we all lived happily ever after.
With High-Z injectors.

If anybody has better facts or a better story, throw it in here!

FIC 1200cc high-z are direct plug in with no adaptors, these are my go to for a street car these days.

That’s what I’m leaning towards. Love your build by the way

Just want to thank you guys for all the replies and insight. Definitely leaning towards some hi z injectors. Most likely FIC 1200cc.

That's the set I have. I can't say anything yet about how they work since my motor is split between two places right now BUT they sure look pretty in their plastic case
