Buying a used BMW engine
BMW engine replacement is usually decided by the cost of the alternative. These are engines where a used unit with known provenance frequently beats repairing the one in the car.
N63 4.4L twin-turbo V82008-2013 (early)
Early versions carry the heaviest reliability reporting in the modern BMW range, covering valve stem seals, high-pressure fuel pumps and timing components. BMW revised the engine over its life, so a later unit is materially different from an early one.
N20 2.0L turbo I4
Timing chain and chain guide wear is the widely reported failure, and it is the reason many N20 vehicles need an engine rather than a repair. Ask about chain history on any donor.
Before you order
BMW revised these engines repeatedly within a single model designation. The VIN is the only reliable way to identify which revision your car takes, and we confirm it before anything ships.

FAQ
Used BMW engines & transmissions
How much does a used BMW engine cost?
Price tracks the engine family more than the model year, and on BMW that usually means which of the N63 4.4L twin-turbo V8 and N20 2.0L turbo I4 you need. Displacement alone does not settle it, because the same badge can cover variants that differ in cost and availability. Tell us the year, model and VIN and you get a firm quote on the engine your vehicle actually takes, with availability confirmed before you pay.

We regularly source BMW engines across the lineup, including the 4.4L V8 Twin-Turbo, 3.0L I6 Turbo Diesel, 3.0L I6 Turbo, 3.0L I6 Twin-Turbo, 3.0L I6 Twin-Turbo Diesel, 3.0L I6. If you don't see your exact engine, tell us the year, model, and VIN and a specialist confirms the right one before you pay.

Will the engine fit my exact BMW?
Fitment is confirmed before you pay. BMW revised these engines repeatedly within a single model designation. The VIN is the only reliable way to identify which revision your car takes, and we confirm it before anything ships. Give us the year, model and 17-digit VIN and a specialist matches the correct engine to your exact application.
Are your used engines and transmissions tested?
Yes. Every used engine and transmission is compression- and oil-pressure tested and put through a rigorous inspection process by automotive experts before they ship.
What warranty comes with a part?

Can I get a longer warranty that covers labor?
