Hi BjornThe Engine core is the same (hence the CFM56 designation) but the dash numbers for the Airbus and the Boeing are different. The 737 uses a CFM56-22B or similar depending on engine thrust rating while the Airbus A319/A320's I work are CFM56-5a1, 5a3 or 5a5 depending on model and thrust requirements. Major difference I could see (not having worked on the 737 alot) are the gearbox and accessory drives. RegardsPaul:-cool
