im doing a b series swap in my EK and i was wondering if the GSR uses a resistor box????

GSR engines/ECU's are not designed around peak/hold injectors with a resistor box. They run saturated injectors without a resistor box as do most OBD1-OBD2 setups. So the answer is no you don't need a resistor box.
