Question 1000cc Injector options

I'm looking for 1000cc injectors for JDM STI v7 heads. So far I've only found the UR ones for $550. These just look like peak & hold low impedance injectors from RC Engineering ($99/each there) but with the resistor pack. My questions are...

Do I need the resistor pack for these particular injectors?
Do I need the UR fuel rails to go with these injectors for my previously mentioned application?
Are there any other high flow (850cc+) injector options for Hydra users?

1000cc Flow-Matched Fuel Injector Kit
(Each injector flowed within 1% to the next)
- 1000cc Low-Impedance Fuel Injectors (Set of 4)
- Resistor Pack Wiring Kit and Connectors

RC Engineering top feed 1000cc 2.5ohm low impedance injectors. Phil said the Hydra can def. run these w/o the resistor box.

Does anyone know if the harnesses are plug and play with stock harnesses?

Also, if anyone's fit these, I read that they are tricky to fit right in top feed fuel rails. I'll be using Perrin WRX top feed rails with my setup.

We have many customers running the low impedance 1000cc injectors with the Element Hydra EMS including myself. We even has good tuned base maps for them.

The Hydra can run low impedance injectors without the resistor box but as stated you need top feed fuel rails. As far as I know only Ultimate makes a direct fit rail. I modified a set of WRX BDL fuel rails to work with the STI TGVs. If you have a WRX or JDM intake manifold for top feed fuel injectors you are good to go.
