OBD conversion, I need some help

OK, I need to convert my car to OBD1. Can I use the OBD0 distributor on the motor and run the car on a OBD1 ECU. I know mike's car ran like this for a while and it didn't seem to have any problems. If I have to use an OBD1 distributor, with it fit onto the Y8 head without modification? Here are the specs for my car...

OBD0 MPFI Car-'90 Civic EX

OBD0 Block-D16A6

OBD2 Head-D16Y8

OBD0 Dizzy-D16A6

0BD1 ECU-P06 or P28

Thanks in advance.

The dist will have the same problem mikes car did, remember when he converted and was still runing a obd-0 dist and it was throwing a code and loosing all power at like 100mph.

That wasn't the problem. His car still did that after he swapped dizzys. Its OK though, I figured out what I have to do.

A mod can close this thread please.

you should use a d15b7 dizzy it will bolt right up to the y8 you could also use a z6 dizzy but the mounting holes wouldnt line up so you would have to get creative. the sensors between obd0 and obd1/2 dizzys are different internally so they cant be mixed, but obd1 and obd2 dizzys work just fine with obd1/2 ecus either or, you can use obd1 dizzy with obd2 ecu or obd2 dizzy with an obd1 ecu...

Rob- I have a d15b7 dist if you need it

OBD2 wont work, the CKP sensor is in the crank pickup by the oil pan, not in the dist.
