probably at minimum, the transmission, engine compartment harness, interior harness, flywheel, clutch and associated hydraulics, clutch pedal and bracket, ecu from a m/t car (which means you will need to reprogram your immobilizer via HDS), and since HDS programming is needed you'll need access to that or an equivalent for key programming, m/t gauge cluster if you dont want to look at the automatic shifter indicators
youd pretty much be stripping the car down to the frame around the firewall to run all the new harnesses and building it back like it was done in the factory
