Depends on how much money you want to spend really
If you bought RS2000 engine mounts, sump, oil pickup etc etc it will bolt straight in. Parts are becoming more expensive though
The 2 litre SOHC will bolt to the 1.3 gearbox if you use 1.6 flywheel but engine mounts and sump will still need sorting with a mig welder and hammer.
You pays your money and makes your choice.
