A Cummins ISX EGR exchange engine with a lower advertised price can cost more once component transfers, fit-up, installation and exchange-core charges are included.
Before choosing a package, confirm:
- What the package includes
- Which components will be transferred from your old engine
- Whether engine fit-up is included
- Whether the condition of your exchange core could create extra charges
- What work and components the warranty covers
AJK Engines currently offers three Cummins ISX EGR package levels:
- Baseline: $39,990 ex GST
- Baseline PLUS: $49,990 ex GST
- Premium: $69,990 ex GST
Each package provides a different level of component replacement. The right option depends on the condition of your truck, the components that can be safely reused and the operational impact of future workshop downtime.
Prices and package details are subject to change. Confirm the current scope, price and inclusions when requesting a written quote.
Compare the Total Cummins ISX Engine Replacement Cost
The cheapest exchange engine is not always the cheapest completed replacement.
A lower-cost package may be suitable when the turbocharger, air compressor, EGR components and other ancillaries remain serviceable. However, reusing worn or unsuitable components can lead to additional parts costs, labour and workshop delays after the replacement has started.
Before comparing package prices, check:
- The long motor rebuild scope
- New and reconditioned components supplied
- Components transferred from the existing engine
- Fit-up and installation charges
- Potential exchange-core charges
- Warranty coverage
- Expected downtime
The commercial effect of downtime should be considered alongside the workshop invoice. The Australian Government reports that freight and logistics account for approximately 8.6% of Australia’s GDP, with more than 75% of non-bulk domestic freight carried by road. For an individual truck operator, this broader reliance on road transport reinforces the need to consider how package scope, component reuse and potential workshop interruptions could affect the vehicle’s return to service.
This provides a more accurate picture of the completed job cost than the advertised engine price alone.

Baseline
The Baseline package provides the lowest entry price in the Cummins ISX EGR range.
Its long motor rebuild scope includes key work and components such as:
- Block preparation, crack testing and machining as required
- Crankshaft work
- New bearings
- New pistons and rings
- New liners
- Reconditioned or new cylinder head as required
- New head gasket and bolts
- Camshaft work
- Rocker servicing
- Timing and assembly to Cummins specifications
Specified components from the old engine can be transferred to the replacement long motor. These may include:
- Injectors
- Engine harness
- ECM
- Fuel system
- Air compressor
- Intake and exhaust manifolds
- Turbocharger
- EGR system
- Engine accessories
Engine fit-up is available for $2,000 plus GST when the old engine is supplied first.
A reconditioned VGT turbocharger and air compressor are not included in the headline package price. They are available at an additional cost on an exchange basis.
Who Should Consider Baseline?
Baseline may suit you when:
- Your existing supporting components have been assessed as serviceable
- You understand which components will be reused
- Controlling upfront spend is your main priority
- You are prepared to assess additional components separately
Do not choose Baseline solely because it has the lowest advertised price. The condition of the transferred components will influence the completed cost and the overall value of the package.
Baseline PLUS
Baseline PLUS increases the supplied component scope while remaining below the Premium price point.
In addition to the core long motor work, it includes:
- New coolant thermostat
- New coolant pump
- Six new diesel injectors and O-rings
- New Jacobs brake harness
- Engine fit-up within the package price
The turbocharger, EGR system, air compressor and some accessories may still be transferred from the old engine.
Who Should Consider Baseline PLUS?
Baseline PLUS may suit you when:
- You want new injectors and key cooling components
- You want engine fit-up included
- You want to reduce the number of older components reused
- Some existing ancillaries remain suitable for transfer
- You do not require the full Premium component scope
This tier provides a middle ground between the lowest upfront price and the broader component replacement included with Premium.
Premium
Premium provides the broadest supplied component scope in the Cummins ISX EGR range.
Alongside the long motor rebuild, it includes:
- Remanufactured or new VGT turbocharger
- Remanufactured or new air compressor
- Refurbished EGR valve
- Refurbished EGR cooler
- New coolant thermostat
- New coolant pump
- Six new diesel injectors and O-rings
- New oil, coolant and fuel filters
- Oil-system priming
- Semi-synthetic engine oil
Who Should Consider Premium?
Premium may suit operators who:
- Want fewer major components transferred from the old engine
- Have concerns about the condition of the turbocharger, air compressor or EGR components
- Want more major component decisions addressed within the package
- Want to reduce the number of older ancillaries carried into the replacement
- Place greater importance on package scope than the lowest initial price
The higher price reflects the broader component scope. It is not simply a more expensive version of the same package.
Five Checks Before Buying a Cummins ISX EGR Exchange Engine
1. Confirm Which Components Will Be Transferred
The condition of your existing components can materially affect the completed job cost.
Ask for a clear list of every item that will be:
- Supplied new
- Reconditioned or remanufactured
- Transferred from the old engine
- Inspected before reuse
- Charged separately if replacement is required
This is particularly important for:
- The turbocharger
- Air compressor
- EGR components
- ECM
- Engine harness
- Fuel-system components
- Engine accessories
A transferred component may still have useful service life. However, it should be reused as an informed decision rather than simply because it falls outside the package scope.
2. Check the Exchange-Core Conditions
The Cummins ISX EGR engines are sold on an exchange basis.
Additional core charges may apply when:
- No exchange engine is supplied
- Parts of the exchange core are missing
- Core components are damaged or unserviceable
Ask what condition the core must be in and which missing or damaged items could create extra charges.
This allows you to compare quotes on a like-for-like basis. A lower advertised price can lose its advantage if the condition of the exchange engine is not considered.
3. Confirm Fit-Up and Installation Costs
Engine fit-up and drive-in, drive-out installation are not the same service.
Engine fit-up generally involves preparing the replacement long motor and transferring the agreed components from the old engine when it is supplied first.
Drive-in, drive-out installation involves bringing the truck to the workshop for a broader engine replacement service. Pricing depends on the truck make, model and job requirements.
For the current packages:
- Baseline fit-up is available for $2,000 plus GST
- Baseline PLUS includes fit-up
- Drive-in, drive-out pricing is available on application
Confirm whether your quote covers:
- Engine removal
- Component transfer
- Replacement of unsuitable transferred components
- Installation
- Fluids and filters
- Testing
- Final commissioning
This prevents confusion between the cost of the exchange engine and the cost of returning the truck to service.
4. Read the Warranty Against the Accepted Quote
The packages are advertised with a 12-month, unlimited-kilometre warranty, subject to conditions.
The warranty scope is tied to the work and components listed on the accepted quote. Important conditions include:
- Parts coverage applies to exchange-engine components listed in the agreed scope of works
- External accessories and items not listed on the quote may be excluded
- Labour coverage applies only when AJK Engines carried out the relevant installation
- The warranty begins from the date of purchase or installation, whichever occurs first
- Defects must be reported in writing within the required claim period
- Proof of purchase and supporting claim information may be required
- Inspection access and return of the engine, truck or component may be required
- The warranty is non-transferable
Read the complete warranty terms before approving the work. Do not rely on the headline warranty period alone.
5. Provide the Correct Engine and Truck Details
Have the correct information ready before requesting a package recommendation or quote:
- Truck make and model
- Engine model
- Engine identification details
- Current engine condition
- Known failure or damage
- Components recently replaced
- Intended truck use
- Preferred fitting option
- Required job outcome
Accurate information helps determine whether the engine and package scope are suitable for the truck.
Which Cummins ISX EGR Package Should You Choose?
Choose Baseline when your existing turbocharger, air compressor, EGR components and supporting parts have been assessed as suitable for reuse. It offers the lowest initial package price, but additional component and fit-up costs may apply.
Choose Baseline PLUS when you want new injectors, key cooling components and engine fit-up included without moving to the full Premium component scope.
Choose Premium when you want the turbocharger, air compressor, injectors and major EGR components addressed within the package. It has the highest initial price but reduces the number of major older ancillaries transferred from the existing engine.
The most suitable option depends on:
- The condition of the existing engine and supporting components
- Which components can be safely reused
- Your installation requirements
- Your available budget
- The operational cost of further workshop interruptions
Request an itemised quote that clearly separates the engine package, transferred components, core conditions, optional parts and installation work.
