From our family to yours, Happy Father’s Day ❤️

Special mention to all the dads on our RPM Mechanical team. We see and appreciate the countless hours you spend away from your own families, the early starts, late finishes and everything in between. Your hard work, commitment and sacrifice play a huge part in making RPM Mechanical the business it is today. We’re incredibly grateful to have you as part of our team.

Today we celebrate each and every Dad, father figure, Stepdad, Grandad, and the incredible Mums who step up and do the work of both Mum and Dad.

Fatherhood isn’t defined by a title. It’s the early mornings, the late nights, the sacrifices nobody sees, the lessons taught, the problems fixed and simply being there when your family needs you.

It’s teaching little hands how to hold a spanner, passing down knowledge from one generation to the next, working hard to provide and still finding the time to kick a footy, ride the motorbikes, take the boat out or read a story before bed.

To the dads working today, the dads doing it tough, the dads we remember and miss, the stepdads who stepped up, the father figures who chose to be there and the mums carrying both roles, today is for you.

Our business was built around family and behind every vehicle we repair is another family relying on it to get home safely.

So from our RPM Mechanical family to yours, thank you for everything you do.

Happy Father’s Day. ❤️

🚛 2014 Isuzu Giga in for a heavy-vehicle ECU tune.

Improved torque, sharper response and better pulling power where a working truck needs it most.

More torque. Less talk. 🚀

🚛 When a concrete agitator breaks down with the brakes locked on, every minute counts.

This brake booster was identifying as an air dryer/water separator… 😂💦

It’s a timely reminder to regularly drain your air tanks and keep the entire air system serviced. Moisture and contamination can quickly cause seized components, brake faults and costly downtime.

We diagnosed the fault, completed the repairs and got this twin steer agitator back on the road and back to pouring concrete. 👌🏽

🔥 1KD HILUX DYNO TUNING 🔥

The Toyota 1KD-FTV is one of our favourite diesel engines to tune and a platform we know exceptionally well.

A healthy, relatively standard 1KD Hilux will commonly produce approximately:

✅ 115–130hp at the wheels standard
✅ 150–170 hp at the wheels after tuning
✅ Approximately 95–140Nm additional torque

They can achieve much higher results with aftermarket accessories.

Results vary depending on engine condition, transmission, tyres and modifications, which is why every Hilux receives its own baseline runs, testing and custom dyno calibration.

Our aim isn’t an aggressive torque spike or a big number for social media. We concentrate on smooth, usable power that improves:

✅ Mid-range torque
✅ Throttle response
✅ Overtaking performance
✅ Hill climbing
✅ Gear holding while towing
✅ Overall driveability

From servicing and diagnostics to intake cleans, injectors, turbo systems and custom dyno tuning, RPM Mechanical & Fraser Coast Diesel is your local Toyota and LandCruiser specialist.

⚰️ Unfortunately, it’s overhaul time for this 1HZ-powered 100 Series LandCruiser.

Once stripped down, the extent of the internal damage became clear:

❌ Melted pistons
❌ Heavily scored cylinder bores
❌ Pre-combustion chamber inserts dislodged from the cylinder head
❌ Significant damage requiring a complete engine overhaul

The Toyota 1HZ has earned its reputation as a simple, dependable and long-lasting diesel engine but even these legendary engines aren’t indestructible.

In an indirect-injection 1HZ, combustion begins inside the pre-combustion chambers in the cylinder head. If these chamber inserts become damaged or experience excessive heat, they can loosen and fall out.

Melted pistons can also indicate excessive combustion temperatures, injector faults, incorrect injection timing, cooling-system problems or a combination of issues.

This is why we don’t simply replace the damaged components and send the vehicle back out. The underlying cause must be identified, or the rebuilt engine could suffer the same fate.

This engine will now require a complete strip-down, inspection and overhaul. The block, crankshaft, connecting rods, cylinder head, pistons and lubrication system will all be carefully inspected and measured. The injectors, fuel system and cooling system will also be thoroughly assessed before the rebuilt engine returns to service. / crate engine.

Warning signs can include:

⚠️ Excessive smoke
⚠️ Increased oil consumption
⚠️ Abnormal knocking
⚠️ Loss of power
⚠️ Overheating
⚠️ Heavy crankcase breathing
⚠️ Difficult starting
⚠️ Increased fuel consumption

There’s a reason Toyotas are the highest-volume vehicles we see through our workshop. It’s not because they’re unreliable it’s because we understand them, enjoy working on them and know the preventative maintenance required to keep them dependable.

From logbook servicing and diagnostics to injectors, cooling systems, intake cleaning, dyno tuning and complete engine overhauls, RPM Mechanical & Fraser Coast Diesel has your LandCruiser covered.

The ultimate touring rig! 🔥

This 200 Series LandCruiser came in for the complete RPM treatment:

✅ Intake manifold clean
✅ Custom dyno tune
✅ Logbook service
✅ Starter motor replacement
✅ New injectors
✅ Transmission service
✅ Upgraded transmission cooler

There’s a reason Toyotas are the highest-volume vehicles we see through our workshop and it’s not because they break down. We love carrying out preventative maintenance, addressing common issues before they become expensive problems and making these already dependable vehicles even more reliable.

They also make unreal gains on the dyno!

📊 Stock: 175hp and 400Nm
🔥 RPM tuned: 290hp and 822Nm

That’s a whopping 115hp and 422Nm increase a 65.7% gain in horsepower and a massive 105.5% gain in torque!

The result is stronger towing performance, improved throttle response, smoother power delivery and less gear hunting exactly what you want from the ultimate touring setup.

With the engine, fuel system, transmission and cooling system properly maintained, this 200 Series is ready to tow, tour and tackle plenty more kilometres.
