Are there other versions of the BMW N74B66?

In our yard the N74B66 is the only listed version of the N74 family. It makes 448 kW (610 HP) and 800 Nm, and was built from 2009 to 2022.

Engines in one family share a basic block, but the turbo, the injection, the sensors and the engine computer can differ. A higher power version often has different pistons, a bigger turbo or a different fuel system.

This is why we ask for the exact code. Fitting a different version can work, but the wiring, the software and sometimes the gearbox must be changed to match.

Not sure? Send us your VIN and your gearbox code. We match the engine family, the year window and the parts on the engine before anything is reserved, and the check is free.
