you will need a whole ea81 or ea71 fat case engine to go with a 5spd, a driveshaft, and clutch/flywheel.

The top mount starter is the issue. The 5 spd trans will bolt in, but not the top starter engine. A ea81 or later model ea71(86 hatch) has the side mount starter.
I am trying to remember bellhousing swap. The bell comes off the engine, but i believe it swaps between ea81 and ea71 fat case. I am not familiar with teh earliest gen of ea71/ea81, someone will chime in
Otherwise, if you swap in a 5spd, it will share the same 23 spline axle if it is from a n/a model. There may be clearance issie in the trans tunnel for the rear (BFH).
Otherwise, ea82 hardware swaps into an ea81 body.

To use your current driveshaft you would have to get it lengthened as the five speed gearbox is shorter than the four.
I believe the five speed may cause some clearance issues with the steering shaft in a 1980 Brat.The dual range four speed and EA81 just barely fit and the five speed box is s fair bit wider near the bell housing.
There is a write-up in the Historic forum that had pics from a member who did this swap.

Simplest would be a four speed but you will have to muck around with the shift levers or find the shifters from a 1981 EA81/dual range Gen 1 Brat.

If you can find the housing from a fat case EA71 you can.
Easier to swap to EA81 engine with 5spd dual range. Easier because easier to find. fat case EA71 not very many in hatches only mostly 2wd
