what are the possible fuel injectors that can be used on the rb25det engine?

Is this a serious question?

With a different fuel rail or the stock one, either top or side feeds above 370cc, whether they're low impedance or high impedance, that can be made to support either with resistors.

They are just a Nissan purple top injector.

ok, not sure if u want to modify ur stock ones or not but heres the skinny...

the rb25det comes with stock 370cc (pretty sure) side fed high impedence injectors.

u can run top fed low impedence injectors by getting a top fed fuel rail and getting resistors to change the impedence to high. u can get 10 ohm resistors at radio shack. one resistor per injector is what i ran.

Or you could order from Deatschwerks. I believe they are a sponsor of NICO. Good prices with a great reputation for reliability.

I'm looking at ordering some top feed injectors to support 500 hp. FYI I'm assuming 700cc will do the trick. Does low resistence correspond to low impedence? And if the injectors are listed as low impedence, do they all have the same amount of resistance so that a 10 ohm resistor to each will keep the ECU happy? Sorry for the newb questions but I'm just getting to this point in my project and haven't really looked into it too far.
