If I bypass the injectors resistors can I still use the stock injectors I bought an 88 rx7 NA and it didn't have the injector box

 

88 year rx7’s are either early or late models. Early models have low impedance injectors with the resistor box. Late models have high impedance injectors without the resistor box.

if it is an early model and you do not have the resistor box installed, you’ll have to add in-line resistors for each injector.
