What this guide covers

Petrol listings include everyday six-cylinders such as the N52, N55, and B58, and M engines such as the S55 and S63 when they are in stock.
A petrol engine is still sold as the photographed unit. Turbo hardware, the intake, and the sump are whatever that listing shows.
Fitment

N55 and B58 are both turbo sixes and they are not a swap. S63 in an X5 M, an X6 M, and an M5 is not one part number across every year.
Manual and automatic petrol cars differ at the flywheel. Confirm that before the engine is crated.
What the workshop checks

The workshop looks at oil pressure evidence, the sump, and visible damage to pulleys, connectors, and the turbo where one is fitted.
