We’ve got the codes, the models, the specs, and the testing to back it up. And yes, we ship anywhere in the USA.
BMW owners don’t do average. Whether you’re driving a 3 Series, X5, or an M car, your machine wasn’t built for point A to point B — it was built for smirking every time you see a speed limit sign. But when that legendary engine starts knocking, smoking, or just flat-out quits, reality sets in fast.
And then comes the question: Do I buy a new BMW engine for the price of a small condo… or get a tested, reliable used BMW engine for thousands less?
At TurboAutoParts, we’re all about making sure you choose the smarter (and way cheaper) option. We’re USA-based, have a commercial address (yes, we actually exist), and we ship tested used BMW engines and transmissions nationwide.

Transmission Codes That Matter Too
If you’re replacing your BMW engine, chances are your transmission could use some love as well. We stock used BMW Transmissions and remanufactured BMW transmissions, including:

All tested, inspected, and ready to ship. Because nothing kills the joy of a fresh engine faster than a gearbox that shifts like it’s in protest.
Why a Used BMW Engine Makes Sense
Let’s talk numbers — because they’re the real reason you’re here.

The Sarcastic Truth About BMW Ownership
Owning a BMW is like dating a supermodel — thrilling, beautiful, but sometimes expensive to maintain. The trick is knowing where to spend your money and where to save it.
A brand-new BMW engine might sound tempting until you realize you could buy a used, tested one from us for half the cost — and still have enough left over to fix all those “minor” things you’ve been ignoring (yes, your parking sensors count).

Your BMW was built to be driven — hard. When its heart gives out, you don’t need to sell it for scraps or remortgage your house. You just need a used BMW engine or transmission from TurboAutoParts.
