Different Stuff....
1.3 G/Box has diff shaft size, release bearing and release bearing clips.
1.3 box uses longer bolts to bolt g/box to eng.
1.3 eng had diff alternator wiring. My 1.0 had a large wire and a plug, 1.3 has two large wires.
1.3 has different size drive shafts and CV joint gearbox side.
Rear gearbox/eng mount is diff.
Front gearbox Mount is diff.
To convert you will need....
Engine and G/Box as one complete lump
Front and rear G/Box mounts.
Both driveshafts complete with CVs boots etc.
Gear change linkage bar.
1.3 ECU
Try to keep the intake manifold on with the TB on too - This will save money on gaskets and the engine can be installed with these items in place.
If you have NATS on your ECU you will need to get the key reprogramed or just keep your 1.0 ECU.
