The parts are the same.
They use the same head.

what about afm and ecu, i'm guessin the ecu will def be different but what bout the afm, also is the loom etc all remain the same.

as i will be hopefully getting the 1.8 engine but will need to put most of the parts off my 1.6 engine onto it,

is the cooling system all the same as well

cheers

Spend some time getting to grips with http://www.realoem.com/bmw/select.do and you'll be able to check individual parts usage on other models etc.
