Performance Engine Builds in Midland, TX

Full in-house performance engine builds at Chris’s Diesel Service in Midland. Disassembly, machine work coordination, and an engine built to your power target, with personal sign off from Chris before it goes back in the truck. This is high performance engine building for customers chasing a number, not a repair, and it is built to hold that number rather than hit it once on a dyno sheet.

Inside Every Build

Power Is Planned. Not Bolted On.

A performance engine is a set of decisions made before the first part is ordered. These are the checks and choices behind every build that leaves the bay.

01 Power target agreed in writing before parts

02 Block and crank measured against tolerances

03 Machine work scoped and coordinated

04 Rotating assembly matched to the target

05 Clearances set for the power, not the catalog

06 Head work and valvetrain matched to airflow

07 Fuel and injection sized with headroom

08 Cooling and oiling upgraded to survive the number

09 Torque specs and clearances on the build sheet

10 Break-in procedure done here, not left to you

11 Verified under load before delivery

12 Signed off personally by Chris

How a Build Runs

Spec It. Build It. Prove It.

Three stages, each documented. You know the target, you see what went in, and the engine proves itself before you take the keys.

The Spec

Target and Teardown

The build starts with an honest conversation about the power you want and what your platform can hold. Then the engine comes apart and gets measured. If the teardown shows the engine simply needs restoring to factory spec, we will say so and point you to a stock diesel engine rebuild instead.

Power target and use case agreed upfront
Straight answer if the goal does not fit the budget
Full teardown and measurement
Machine work scoped where needed
Itemized quote before the build begins

The Build

Assembled In-House

One shop, start to finish. Parts selected for the target, clearances set for the power level, and every spec recorded as it goes together.

Chris and his team assemble every engine here
OEM internals where they exist, proven parts where they do not
Clearances verified, never assumed from the box
Supporting systems upgraded to match
Build sheet filled out as it goes together

The Proof

Run Before Delivery

Proper break-in, then the engine runs under load before delivery. If we would not drive it hard ourselves, it does not leave.

Break-in procedure completed in-house
Oil pressure and temps verified against spec
Leaks checked hot and corrected
Test-driven and signed off by Chris
Service guidance for the first miles in writing

Standards and Capability

Built to Hold the Number. Not Just Hit It.

Anyone can sell you horsepower. The build that survives horsepower is the harder job, and it is the only kind we do. If you need it done fast and cheap, we are not your shop. If you need a performance engine builder in Midland, Odessa, or anywhere across the Permian Basin who will tell you the truth about your platform, we are.

Lifetime of Craft Chris has built engines since age 12 in his father’s shop, including race experience with go-karts and bikes. Performance is where this shop started.
Honest Ceilings We tell you what your block, fuel system, and drivetrain can hold before you spend. No selling a number the platform cannot survive.
Parts Standard OEM internals where they exist, proven performance parts where they do not. No no-name rotating assemblies at 3,000 rpm under boost.
Whole-Truck Thinking Drivetrain, cooling, and fuel and tuning upgrades quoted alongside the engine, because power without support is a failure waiting to happen.

Engine Build FAQ

Common Questions

Do you build performance engines in-house?

Yes. Chris and his team build every performance engine in our 140 x 150 ft Midland shop. Machine work is coordinated with trusted machine shops, but measurement, assembly, break-in, and sign off all happen here. Nothing is drop-shipped from a catalog builder with your name on the invoice.

What is the difference between a performance engine build and an engine rebuild?

A rebuild restores a worn or failed engine to factory specification so it runs reliably again. A performance build starts from a power target you want that the engine was never designed to make, which changes the parts, the clearances, and the supporting systems. If your engine is tired rather than underpowered, a rebuild is the cheaper and better answer, and we will tell you that.

What platforms do you build?

Diesel platforms are the specialty, including Power Stroke, Duramax, and Cummins, with built 6.7 Cummins and 5.9 Cummins engines among the most common requests. We build gas performance engines as well. Call (432) 557-6500 with your platform and power goal, and we will tell you honestly whether the combination makes sense.

How much power can my stock engine handle?

Every platform has a ceiling where stock internals, head fasteners, or fuel systems give up. Part of the build conversation is mapping your goal against those limits, so the money goes into the parts that actually need upgrading. We would rather talk you down a number than sell you a failure.

How long does a performance engine build take?

It depends on machine work queues and parts availability for your combination, and performance parts lead times can be long. You get a realistic timeline with the quote, and honest updates if something slips. What we do not do is rush assembly to hit a date.

What does a performance engine build cost in Midland, TX?

The honest answer is that the power target sets the price, which is why the target comes first. After teardown and measurement you get an itemized quote covering machine work, parts, and assembly before the build begins. Bring the goal and we will price the real path to it.

Have a Number in Mind?

Bring the goal. We will tell you what it takes to build it right, what your platform can hold, and what it costs before a single part is ordered. Serving Midland, Odessa, and the Permian Basin.
