This plan has the feeling of 'avoid' about it. Just hold out a bit longer for the right engine. It's not a rare car so the engine will be available and won't be expensive. Keep looking.

They're exactly the same, as long as the throttle body is the the one you are swapping with - the 1.4 came in SPi and MPi. The Spi has a plastic circular plenum in the TB and the MPi has an aluminium plenum. Other than that, you can swap them over. I think the engine codes are C14NZ for the Single Point Injection, and the C14SE for the Multi Point Injection.

Make sure the crank pickups are in the right place. I think some are on the pulley and some are internal and I can't remember which way round it is in reference to age.
