Pre NATS 1.3 engine into 1.0 NATS car

I've picked up a low miles complete1.3 distributor engined car.. I want to fit the 1.3 into my 1.0 NATS equipped car.. Besides the engine, what electronics do I need to change? Will the pre NATS 1.3 ECU plug straight into my NATS 1.0 loom?

Should have added that my 1.0 NATS car has distributor engine also
