to do this youll need an 1.4 efi loom, ecu and possibly edis (cant remember if there internal or external edis [electronic distributerles ignition system)

youl also need the inlet manifold, fuel injectors, pump, fuel lines, possibly the swirl pot, also the air filter (unless you have a cone filter) youll also need the fuel pressure regulater and asociated vacum hosing,

to be honest would be far simpler to go to carbs, and even with the efi instaled you would only get around 70 bhp, not worth it
would be far simpler to stick a set of webber 40's on there and a kent cam

or an engine swap to a xr2 engine with carb
