Hello everyone

Long story short I bought a D16Y8 out of a 2000 Civic DX, after research I found out that I cannot use the ECU or wiring harness that came with the D16Y8. Am i correct in the assumption that in order to get the engine running I will need to use the OBD1 harness with the OBD2b engine and change the dizzy by rewiring it into a 2 pin configuration (I do have the OBD 1 dizzy), add wires for VTEC, knock sensor and O2 sensor. I may also need to add the obd1 injectors.

Cliff notes -
93 del sol OBD1 harness onto 2000 Civic DX D16y8
Need to change distributor possibly
Need to add VTEC and sensor wires, IACV wires need changed as well
Unsure if fuel injectors also need to be swapped out
p2p ECU from 2000 civic
p28 ECU from Del sol

 

As you will run the Y8 engine on an OBD1 P28 ECU, you do not need to use any OBD2B wire harnesses and you don't need to connect the knock or CKF sensors. I believe the Y8 injectors would be okay.

 

If you move the D16Z6 fuel injectors over to the D16Y8 engine, you will not have to change fuel injector clips on your original Del Sol engine harness. They will fit without modification. The two engines are rated within 2 HP of each other... the P28 ECU should be close enough to run it fairly well.
