Which BMW swap engine fits your car?

The BMW swap engines in stock carry the N57, M54, N55, S55, N54 and M57 codes. The same badge can hide different engines across build years, so compare the code stamped on your block with the one in the listing.

To be sure of fit, send the VIN by WhatsApp or email. The desk confirms the code, the gearbox and the extra parts, then reserves the unit while payment clears.

Looked at in Hamburg, shipped to the UK, Europe and the US

Every engine is photographed on the bench at Andreas Meyer Straße 38 before it is listed, so the pictures show the unit that ships, not a stock image. Turbos, injectors, sensors and the sump are described as fitted, and anything missing is written into the listing.

Delivery costs 249 € on every order, wherever it goes. Within the EU the pallet moves without customs in 1–5 working days; for the UK, the US, the UAE and other destinations outside the EU, the desk supplies the commercial invoice and import duty and VAT are paid on arrival.
