BMW Engines We Cover

Real BMW engines from our climate-controlled warehouse, tested and ready to ship. Our inventory spans every major BMW engine family — from the legendary M54 naturally aspirated inline-6 to the current B58 turbo and the M-division S63 and S85 high-performance V8s and V10s.

Why Buy a Used BMW Engine from Auto Power Source

BMW engines reward the right buyer and punish the wrong one. The N20 four-cylinder, N52 naturally aspirated inline-6, N54 and N55 turbocharged inline-6s, N62 V8, N63 hot-vee V8, B58 modular six, and the M-division S55/S63/S65/S85 powerplants each have specific VANOS layouts, eccentric-shaft sensors, valve cover gaskets, oil-feed lines, and timing-chain guides that vary by chassis code and production year. A wrong donor engine — even within the same nominal displacement — can mean wasted weeks, return freight, and an engine bay full of incompatible plumbing.

Our 1,301 verified BMW engines have all been pulled from low-mileage donor vehicles, cataloged by VIN and chassis code (E46, E60, E70, E90, F10, F30, G05, G30, etc.), and held in our climate-controlled warehouse pending sale. Each unit went through our six-step inspection: VIN-matching against your chassis, compression and leak-down testing by ASE-certified technicians, noise and smoke verification on the test stand, visual inspection of VANOS solenoids and oil-feed plumbing, multi-angle photography sent for your approval, and palletized shipping.

You pay a fraction of dealer-new pricing for the same BMW Motorsport engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and have 30 days from delivery to return for any reason — no restocking fees, no return freight charges. Up to a 3-year warranty covers you after install. Across 46,000+ engines and transmissions shipped, our fitment-related return rate sits at 0% because we verify before we send. Our team is available 24 hours Mon-Sat.

Most BMW owners face four real choices when their engine fails — and BMW dealer-new pricing is among the steepest in the industry:

Tested used OEM hits the sweet spot — same BMW engineering as new, fraction of the cost.

BMW Engine Buying Guide

BMW engine procurement is more chassis-code-driven than almost any other brand we ship. Within the same model year, the same displacement, even the same family designation, BMW will use different intake plenums, oil pans, and harnesses depending on whether the donor was an E-, F-, or G-series chassis, RWD or xDrive, and pre- or post-LCI facelift. Six things to verify before buying a used BMW engine:

1. Match the engine code, not just the displacement. BMW uses multiple engines at the same displacement across generations — a 3.0L could be M54, N52, N54, N55, B58, or even S54 depending on the chassis. Your VIN's 8th digit and the chassis code together pinpoint the exact engine family.
2. Confirm chassis code compatibility. Same engine family (e.g. N55) was used across E-series, F-series and G-series chassis with different oil pans, intake manifolds, wiring harnesses, and exhaust manifolds. An F30 N55 will not bolt cleanly into an E92 without bracket and harness changes.
3. Specify RWD vs xDrive (AWD). Oil pan geometry and front sump shape differ. Order the wrong one and the engine will not clear the front diff or driveshaft on an xDrive car.
4. For N54 / N55 / S55 turbo engines, ask about HPFP, wastegates, and timing-chain history. These are the well-known wear points; a good donor engine should disclose any prior replacements or the original mileage on critical components.
5. For V8s (N62 / N63 / S63 / S65 / S85), confirm timing-chain-guide and rod-bearing replacement history. N63 valve-stem-seal recalls and S65 rod-bearing service intervals are make-or-break details for any used V8 donor.
6. Pre- vs post-LCI matters more than you think. BMW often refreshes harnesses, sensor placement, and ECU mappings mid-cycle. A 2014 F30 N20 from before the LCI window will not always plug-and-play into a 2016 post-LCI car. We verify LCI status during VIN matching.

Our ASE-certified technicians verify every one of these points against your VIN and chassis code before any BMW engine ships.
