Adding a new engine is a challenge in itself, whether you’re restoring an old classic vehicle or seeking to upgrade a newer truck or car. But more options are available to you than you might think—regardless of whether you’re adding an engine. For instance, you have the option to buy a brand-new engine or to create one from scratch. But should you buy or build your crate engine? It’s entirely up to you and depends on the project’s circumstances. Here are a few pros and cons for both choices to help you make your decision.

Buying an Engine: Pros

A crate engine is one that a manufacturer ships to you in, yes, a crate. They arrive intact and ready to install. They come with all the necessary parts, though these parts may vary according to the type of crate engine the manufacturer offers. Most engines are available. For example, you may find a 5.9 Cummins motor for sale and ready to ship. They usually come with warranties but you should confirm this with the manufacturer. All in all, buying a crate engine isn’t a bad plan if you know what you’re doing.

Buying an Engine: Cons

Of course, nothing is ever that easy. Be sure you know what you’re doing if you choose to buy and install a crate engine or find someone who does. You’ll need the space, tools, and know-how to drop the engine into your vehicle and hook it up. And the margin for error is slim. Also, make sure your bank account can handle the blow. Some engines can cost tens of thousands of dollars. Add to that any fees for garage space or a mechanic’s time, effort, and knowledge. These crate engines are no LEGO kits!

Building an Engine: Pros

The challenge of building an engine might be preferable to buying one pre-assembled if time, money, and talent are no problem. You get to see your engine from beginning to end, inside and out. While not cheap, building your engine is also relatively cheaper than buying a new one, and you can make decisions along the way to spend on specific parts as you see fit. Finally, you’ll feel a sense of accomplishment that comes with building rather than buying your engine, not to mention bragging rights.

Building an Engine: Cons

You didn’t think it would be that easy, did you? While building can be cheaper than buying, it’s still going to cost you. As with any project, calculate a budget, and then figure on paying twice as much to finish the project. You’ll also lose a lot of time, since building an engine requires months, not days, of work. Moreover, unless you’re a mechanical genius, the engine you build probably won’t match the quality of a product made by fleets of engineers and experts. A single mistake can quickly set your timeline back and send you back to your supplier for a very expensive square.
