The weight of the HR12DDR engine according to the catalog is 91 kg. The engine number is located at the junction with the gearbox. This is a reliable motor and the main complaints on the forum are related to noise and vibrations. The compressor runs for a long time if its lubrication is changed, but sometimes its hose bursts. Like all direct injection engines, the intake valves quickly accumulate carbon deposits. Weak points of the unit also include the ignition block relay, catalytic converter, and EGR valve. Don't forget about adjusting the thermal clearance of the valves, there are no hydraulic compensators here.
