I want to convert my 91 da to obd1 however i have some dsm 450 blue tops i want to use on my turbo set up... can i still use them? as far as i know to convert all i need is a obd0 to obd1 conversion harness like from http://www.boomslang.us a obd1 distributor and a 4 wire o2 sensor, i cant find info about the injectors... i know obd1 cars use saturated injectors so i just wanted to make sure any help would be appreciated

 

You can use them.

All Honda ECUs want to "see" a high impedance injector. In the early days, they did this by using a low impedance injector + resistor box. In the 92+ cars, they simply did it with a high impedance injector.

Yup.. You just need to run a resistor box which if you were obd0 before you will already have one..

 

If you want to run the DSM injectors, you will need to keep the resistor box in your car. If you ever decide to run OBD1/2 injectors, you will remove the resistor box and solder the 5 wires together or run a junction connector to close the circuit.
