Hi, I change ecu to obd1 on my Honda civic D16A8 ZC engine, if some one suggested what kind of injection need for those upgrading to remove the resistor box?

 

You need high impedance (aka high resistance) injectors to be able to remove the resistor box. If you have access to an ohm meter, you can check the resistance across the two pins on the injector - you want an injector with 10-14 ohm resistance to be able to delete the resistor box. A low impedance injector will read 2-4 ohm.

 

Thanks for your reply, but from which model honda will be for direct fit.

 

Most 92-00 Honda Civic and 94-01 Acura Integra injectors are 240 cc/min high impedance injectors and will work for what you need. Some are only 190 cc/min. Unfortunately I don't think there is a way to tell which ones you have unless you have them flow tested. There are also aftermarket injectors you can buy.
