Hey Nick welcome to the states, hope y'all have a great time!
If you looking at things you can pack in your suit case, here is some I would think will work.
Fuel filters, inline and fuel pump sock.
Fuel pump
Fuel injectors as well the throttle body rebuild kit, throttle position sensor, Idle air control
ECM
Distributor cap, rotor, pickup coil, wires and plugs
Transmission filter
LED lights?
Just a few things that come to mind!
