from memory
lamps out
bumper off (torx underside and 10mm's to wings then pull)
front panel off with its hoses and wiring
inlet off (fuel pipe is squeeze fit)inc its maf etc (hook it all up if possible if you have trouble with wiring etc)
starter off
battery and tub off
exhaust manifold off head
bolts out of gearbox to engine joint,
engine mount loose
lift engine a bit and remove the mount then wiggle the engine free from the box
and remove it
leave the p/s pump in the bay but off the engine the same with the aircon if possible but you will have to be very carefull if you leave it connected to the aircon rad
cant be much else, then its check new engines parts (if super low miles all is good)
slide it into the box , fit top mount and get the bolts into teh box/engine joint
and its all getting there
