as far as i can make out ill need the chip from the ignition key of the donor along with the ecu to enable the immobiliser to work so thats no problem,ive managed to find the g/box ratios for the 1.6 just to make sure theyre the same but i cant find a thing on the 1.4 ones to compare

i plan to find a written off donor and take the engine/ecu/clocks/ign key chip all from the same car,just need to confirm if i need the box as well??
