I have 91 CRX Si, & I just bought a JDM D15B VTEC to swap into my car... I have been searching the forum here, and reading... I am going to be running the P28 ECU, and convert to OBD1... So I know I need a 4 wire O2, OBD1 dizzy, and the injectors are optional (meaning I can use my a6 injectors or convert them to the z6)... But what else, if anything is OBD1 specific? On my new engine almost all of the sensors are beat to hell and back... So my question is, what all sensors can I reuse? Are they different from my pre-OBD sensors?

The sensors I know that are visually damaged and need to be replaced:
Themoswitch
Intake Air Temp. Sensor
MAP sensor (someone said this would work, but I dont see how if its supposed to mount ontop of the intake mani on the D15B, and its on my firewall on the my D16A6)

Thanks in advance...

 

bump....

 

Yes you can reuse some sensors. As for the ones you are wanting to, you can reuse your stock map sensor, but will need to run a line from the opening in the new TB or cap it off and run a line to a vacuum intake manifold source.

IATs will switch over, but the thermoswitch....if you are referring to the one on the thermostat housing....is not going to work.

 

Sweet thanks man!
