Heavy-Duty Diesel Engine Conversions

Engine conversion solutions designed to improve performance, compatibility, and service life for demanding heavy-duty applications.

Proven Diesel Re-Power Solutions

There are times when rebuilding an engine is not the best long-term decision. Chronic failures, poor parts availability, excessive maintenance cost, or ongoing downtime can turn a good truck or valuable piece of equipment into a constant liability. When that happens, the answer is not another repair. It is the right powerplant.

TOP GUN HD performs professional diesel engine conversions for heavy-duty trucks and large industrial equipment across Alberta, helping operators upgrade to proven, dependable engine platforms built for real-world work.

Ready To Talk Through Your Options?

Let us help you decide whether a rebuild or conversion is the right move.

When An Engine Conversion Makes Sense

You know its time to consider an engine conversion when:

The truck or equipment is worth keeping, but not with its current engine

There is value in standardizing engines across multiple units

Parts availability and cost have become unsustainable

Downtime has become routine rather than exception

The current engine has known reliability concerns

You are about to mile-out your current engine

A well-planned conversion protects investment, supports uptime, and reduces long-term operating stress.

On-Road Heavy-Duty Engine Conversions

Reliable Power For Working Trucks

Highway tractors, vocational trucks, oilfield units, tankers, vac trucks, hot oilers, dump trucks, and specialized heavy trucks demand stable, dependable power. When the original engine is known for chronic problems or has reached a point where rebuilding no longer makes sense, a conversion can extend the life of the truck and stabilize maintenance planning.

We support conversions involving major heavy-duty engine platforms including:

  • Cummins
  • Detroit Diesel
  • Caterpillar
  • PACCAR/MX
  • Volvo/Mack
  • Navistar
  • and similar

Off-Road Equipment Engine Conversions

Dependable Power For Industrial Equipment
Large industrial equipment cannot afford unreliable engines. When a critical machine spends more time down than producing, projects, safety, and operations are directly affected. TOP GUN HD provides engine conversions for major off-road equipment, helping operators replace problematic powerplants with proven diesel platforms suited to Alberta’s industrial environments.
This applies to:

  • Mining equipment
  • construction machinery
  • Civil and pipeline equipment
  • Forestry machines
  • And other large diesel-powered assets.

Our Approach To ​Engine Conversions

Engine conversions must be completed with planning, accuracy, and professional integration. TOP GUN HD takes a structured approach:

Integration planning including mounting, cooling, electrical, ECU, exhaust, and emissions requirements

Clear discussion of goals, cost considerations, and reliability expectations

Final verification, documentation, and delivery of a truly work-ready unit

Assessment of current engine condition and operational demands

Selection of a suitable replacement engine platform

Professional installation and controlled testing

Conversions can be performed in our facility or at your site.
