1.4 gearbox swap question

[Chicodelacurva]

I have a 1.4 coilpack k11 and a spare 1.0 gearbox. Turns out the gearbox doesn't have the hole for the flywheel sensor so I guess I can't use it on my car.

The question is if it's possible to put the 1.0 gearbox diff in my current gearbox, as it would have the same effect as a gearbox swap.

Thank you in advance.

Swapping just the diff won't change much assuming it's a standard diff, I assume you want the shorter ratio for more rpm. The crownwheel would swap but it's paired to a gear that's integrated into the gearbox layshaft so would need to be changed as well.
You could see if the bell housing side of your 1.4 box will bolt up to the other side of the 1.0 gearbox.
