when you order an adjustable fuel pressure regulator do you order it for the car or for the engine? also what kind of intjectors do i need for a 1993 integra xsi b16a? high resistance or low resistance?

 

You will need to order one for the engine. As far as injectors if you are not running a resistor box you will need high impedance injectors.

 

where is the resistor box? im not to sure if i have one

 

Its on the driver side of the engine compartment, up by the firewall...its grey about 4"x4" and has heat louvers ontop of it...has a green connector with 4 red/black wires coming out of it...also a white connector with multiple wires...not hard to find
