Get a donor car instead of a lump from the scrappy then you can get the engine running away from the main loom before you remove it from your donor
it will also give you an idea of how the fuel sustem works ie pumps filters

you will also need
wiring loom and ecu
drive shafts
radiator and all hoses to be safe cooling fans
gearbox and a way to connect it to the shifter
engine mounts
exhaust
the engine may bolt straight in then its plain sailing reli
WELL IT CAN BE ARRRH !!!!!!! good luck dave
throttle cable clutch cable if you have a hydralic clutch on your car your away if not a pedal box will be needed
