How long does an engine conversion take?

Short answer: Probably somewhere between 40 to 60 hours.

Longer answer: It's going to depend on a variety of things: the make/model of the engine, the transmission being used, and the vehicle that’s being repowered.

If you're looking to convert something pre-computer, a set of engine mounts and a few adapters can get you there pretty fast. Then it's just a matter of the fabrication, wiring, and welding necessary to get fuel delivery, cooling, and exhaust systems sorted out.

What's JE-CO Truck & Trailer's process for engine conversions?

Performing a diesel-engine swap isn’t easy. It takes time, knowledge, and patience. That's why we start every project with a conversation. Before we dive into the specifics, we want to find out your goals for the conversion so that we can point you in the right direction as the inevitable onslaught of choices come up along the conversion road.

What's the hardest part of converting?

The biggest component of a swap involves all of the new electrical work. It is the most time consuming, the most challenging and often requires the most skill. We'll keep you informed throughout the process and ensure that you're aware of the work we're doing, adjustments to timelines, budget, and more.

Where should I start?

Swing by the shop and we'd be more than happy to start the conversion conversation.

Or, give us a call and we'll go over your options on the phone.

Great job! I was desperate removing 65 mph speed limit from my Sprinter 2500. I checked major dealerships and mechanic shops all over the country, non of them couldn’t do it. I was already losing hope. This guys rocks. Well done! Thank you!

These guys were great! They are open 7 days/week, which is why I found them. They diagnosed and rebuilt the power divider on my 2000 Pete. G and the staff were excellent with their communication. They will be my first call if I ever need work done in the Denver area. Thanks Jeco!
