How much power and torque does the BMW M20B25 have?
From the factory the BMW M20B25 makes 126 kW (171 HP) and 226 Nm of torque. It is a 2.5 liter (2,494 cc) inline 6, SOHC, 12 valve petrol engine with no turbo (naturally aspirated).
Without a turbo, the power builds smoothly with the revs. A clean air intake, healthy ignition and the correct fuel are key to getting the full figure.
A used engine reaches its factory numbers when it is fitted with the matching engine computer and software, and serviced with the right oil and filters. If the engine computer from your car is a different version, a specialist may need to code it.
Every M20B25 on our site lists its year and mileage. Ask the desk for more pictures of any listing. We are happy to show the stamp, the ports and the ancillaries before you decide.
