This specific BMW E36 gearbox mount makes it easy to fit a BMW 325TDS (M51) gearbox to a BMW M50, M52, S50 or S54 petrol engine.

---

When a diesel gearbox is fitted to a petrol engine, the mechanical assembly (housing, clutch, engine mount) fits perfectly.

However, the angle of inclination of the engine/gearbox differs, which normally requires the gearbox mount to be modified or completely rebuilt.

This bracket has been specially designed to correct this angle, making assembly simple, reliable and durable.

Why use a 325TDS gearbox on a petrol E36?

On BMW E36 :

• 325TDS engines (M51D25) are fitted at an angle of 24° to the passenger side.
• M50 / M3 E36 petrol engines are fitted at an angle of 30°.

This difference in orientation makes the original gearbox mount incompatible.

This support allows the diesel gearbox to be perfectly adapted to the orientation of the petrol engine, while maintaining a clean and solid assembly.
