Well youd probably have to chip it... Since im sure the fuel maps on the DOHC VTECs are more 'potent' than the P28s...

But yes, you can get a conversion harness from rywire...

Plus youll also need other things to do an OBD1 conversion... An OBD1 dizzy and a 4 wire O2 sensor... And an optional toggle switch (for the new check engine light of the OBD1 ECUs, u have to complete a circuit between 2 of the wires on the ECU to pull the codes from it, most just use a switch)...
