should i upgrade sensor's to ob2a or just use a obd2 to obd1 harness ?
does anyone know if i can use the crank sensor it the dizzy with an obd2a ecu? or does it have to be in the oil pump ?

what other parts can i use from 95 integra . can i use rear disc's oh ya my car is a 1996 cx hatch

 

All you need is the obd2a to obd1 jumper harness and use the P75 ecu that comes with that motor .

Then you will need to change the alternator plug and distributor plug and swap in the injector connectors from the obd1 engine ( if you have the harness ).
