About Us

Automotive Diesel Engines

Choate Engineering Performance (Automotive) specializes in fixing problems. Specifically problems with your diesel engine. Whether you drive a 5.9/6.7 Cummins a Ford Powerstroke Diesel or a Isuzu/GM Duramax 6.6 pickup truck. We know the problems and have the solutions! Not only do we reman diesel engines for the Ford, Dodge Ram, and Chevy/GM owners. But we also design, engineer, and machine these fixes in house. Be sure to check out our Choate Products page for these items.

Reman Vs. Rebuilt 

Our reman diesel engines are completely redesigned and machined to provide durability and longevity. It’s very important to understand the difference between a reman diesel engine and a rebuilt diesel engine. A diesel reman engine is built back  better than new. Meeting or exceeding factory specifications. The rebuilt engine means that it has been torn down, inspected, and repaired as seen necessary. Machining is not always mandated in a “rebuilt” engine. So it is important to compare, and educate yourself as the consumer. An educated consumer will make the right choice. Our engines exceed the specifications of the factory.

 “Only gas engines need balancing, diesels spin slower.”

 Balanced rotational assemblies have proven to drastically increase the bearing lifespan of any engine. Notwithstanding the heavy reciprocating mass of the diesel engine. Whether its issues Ford had from the headgasket failure of the Ford Powerstroke 6.0. The cracked pistons of the Ford Powerstroke 6.4. The valve wear of the Ford Powerstroke 7.3. The spun bearings and oiling system issues of the Ford Powerstroke 6.7. The cracked 53 Cummins block, or valve seat failures of the Cummins 6.7. Or the…..expensive disaster of Cummins. And broken crankshafts of the GM/Chevrolet duramax……..we have a solution. Because at Choate Engineering Performance, “Stock is not an Option!” 

Heavy Duty and High Horsepower Diesel Engines

Choate Engineering Performance (Industrial) no matter the application, has the solution! Diesel is the core of our existence. There isn’t many options for a remanufactured diesel engine in the industrial world other than the OE. We understand the need for the people that depend on the performance of these engines. And that is why we are a “performance” engine remanufacturer. Most in this sector think of “performance” as a nitro top fuel engine. But if an engine continues to perform, when the original has failed, we call that a performance engine.  Whether it be a small Yanmar, Kubota, Mitsubishi, or Shibaura. To a QSK Cummins or 3500 Caterpillar and everything in between, you need reliability! Our versatility of the aftermarket allows us to do things that the OEM can’t. It allows us the flexibility to go outside of the corporate mindset. 

Quality over Quantity

We aren’t building hundreds of thousands of prodution engines. So savings to the customer means the additional time it takes to do it right. And higher quality components to make sure you stay up and going. So if you are in forestry, construction, marine, oil and gas, stationary power, work handling, transportation, OTR, rail, fleet, agricultural, or anything else, let Choate repower your business!

If you have listened to any of our podcasts  (and if you haven’t, check our podcasts here), you may have heard us reference machine shop frustrations.
 

Let me put it this way, imagine going down into the Grand Canyon while trusting someone to hold the rope for you hundreds of feet suspended over the ledge. 

It may sound like an over-exaggeration, but  it’s a very applicable example of what it’s like trusting a machine shop to make sure that all tolerances, clearances, and specifications are correct.

You spend a tremendous amount of time, especially on a diesel engine, to reassemble it. Many times calling for cab removal to install it. The last thing you want to do is get it all back together just to find that the machine shop, the one you trusted in, let go of the proverbial rope. 

Having found ourselves in that exact situation, and with no help from the machine shops we dealt with we made a decision.

We would hold our own rope!

We either would completely get out of this business or we would invest thousands and thousands of dollars into what is one of the top machine shops in the country.

And so we threw our efforts and finances into what is now known as “Choate Engineering Performance”.

Today, we offer you the amazing capabilities we always wanted
the machine shops we dealt with to have, but they
would never make the required investment.

With 4 and 5 axis capabilities as well as flow bench and testing equipment we can handle anything that comes through our doors! Assuring that quality control stays in our hands and in-house we are happy and secure in the knowledge that each engine that ships out all over the country has met or exceeded the high standards we have for it.
