Installer in Sydney for Landcruiser 79 4WD upgrades

We love working on Toyota Landcruiser 79’s in our 4WD workshop in Sydney. It is such a durable, tough 4WD vehicle to use for work or camping in Australia. Some will say it is a ‘real 4WD’ that is perfectly suited to Australia’s tough driving conditions. 

Jamie’s uses his 2021 Toyota Landcruiser 79 for heavy load hauling, carrying things with the rear tray as well as taking it off road to go 4WD’ing when he is not working. Even though this 79 has a diesel powered 4.5 litre V8 he wanted to improve the Landscruiser’s engine power.

We organised for it to be taken to Berrima Diesel to get an engine tune to improve driveability as well as total power output. Getting your 4WD diesel engine tuned in Sydney helps to modify the standard factory settings to better optimise your engine’s dynamic outputs. Most tunes for 4WD engines coming from a manufacturer are relatively conservative as they need to cater to a really wide array of uses as well as by suitable to be covered under warranty. Berrima Diesel will spend some time to understand your needs before their tuning is done on your 4WD engine to unlock improved performance to suit your application/s. Most of the time owners want more torque because they are transporting a boatcaravan or even trail bikes not just on road, but along trails or even water crossings.

We also made sure Jamie thought about managing all that extra power & torque with;

  • A new heavy duty clutch and flywheel to replace the standard factory fitted item. This is needed to manage the increased torque loads from the engine.
  • Improving the Landcruiser 4WD’s braking capacity with an upgraded brake package from Bendix that included new calipers, discs & rotors.

The team in our 4WD shop in Sydney will always remind owners that there is not much point improving engine performance but leaving the other factory fitted items on the vehicle in their standard specification. Sure, most manufacturer fitted parts will be good tolerances, but most likely they will fail sooner rather than later as they attempt to manage the extra performance demands from the vehicle. Just think about any motor racing application, there is literally nothing other than the badge of the manufacturer that is left ‘standard’ as performance improvements are made to the vehicle. 

A road going 4WD is no different. Engine & drivetrain improvements require the supporting items to be able to handle the extra outputs.

To round out the upgrades we installed on this Landcruiser 4WD in our workshop, Jamie also chose to get a billet sealed alternator installed. This waterproof alternator is perfect for water crossings and will continue to function as water enters the engine bay. The other item that was installed on this 4WD was a new Cel Fi Go signal booster to improve his capabilities in remote locations to keep in touch using telephone or internet connectivity.

Rapid Power alternator installed on a Toyota Landscruiser 79 in Sydney



Rapid Power makes a range of full sealed, water-cooled, alternators that are designed specifically for different 4WD vehicles. We installed a brand new Rapid Power PR1TWC-14/200 onto this Landcruiser 79. This type of alternator is designed to be used in really dusty, wet and corrosive driving conditions with its sealed design. It mounts onto the oem engine brackets and also uses the factory fitted drive belt. This means you can upgrade your alternator without having to modify other parts of the engine.

Using a sealed alternator can help improve reliability especially if you plan on going 4WD’ing in sand dunes, beaches, through river crossings, the outback or even on local tracks that can get quite dusty in dryer months. 

Rapid Power alternators produce significantly more output than existing standard alternators. Their design features are engineered beyond those of conventional alternators like the rectifiers that are manufactured with high temp genuine Bosch Zener diodes mounted into highly efficient heat-sinks.

The vehicle already has a snorkel so a water tight alternator makes a perfect combination to ensure the engine will keep working in harsh driving conditions or while submerged in a river crossing.

Front and rear brake upgrade installer for a Landcruiser 79


If you have been around for a while you will know Bendix quite well. They make OEM as well as aftermarket brake products including rotors, calipers and pads like their Bendix Ultimate 4WD Brake upgrade kit

This is one of the best kits to buy and have fitted to your 4WD. There are different specification kits to suite different vehicle models and they include brake pads, rotors, braided lines and a host of ancillary items to replace the factory fitted items on a 4WD vehicles like a Landcruiser.
This kit included
  • 2 x Ultimate Brake Rotors
  • 1 x Set of Ultimate 4WD Brake Pads
  • 1 x Vehicle Set Ultimate Brake Hose
  • 1L Heavy Duty Brake Fluid
  • 1 x Can Bendix Cleanup
  • 1 x Tube Ceramasil Brake Parts Lubricant
  • Bendix rotor wipes

This type of upgrade will give you a firmer brake pedal that won’t over expand under pressure, a reduction in brake dust and braking noise along with thermal stability in high temperatures and a much greater resistance to brake fade.

That is just the fronts!

Jamie also also chose to upgrade the rear brakes too plus improve braking strenght with an upgraded brake booster. Doing this type of brake upgrade front and rear takes your 4WD to a whole new level of stopping performance. Great for carrying heavy loads, towing or even controlling your vehicle on steep declines.


Heavy duty clutch upgrade installer for a Landcruiser 79


With the extra power from the engine tune we suggested the clutch get upgraded to deal with the extra power, torque & help cope with the heavy payloads he was planning to haul.

The NPC Super Heavy Duty Organic Clutch Kit in a 1300nm size was chosen for this application. It is coupled with a dedicated billet steel flywheel and installed as a set in our workshop in Sydney. It is designed to give you smooth engagement & drivability for all kinds of 4 x 4 driving applications.

It suits the VDJ76 series wagon 4.5L 1VDFTV V8 turbo diesel, VDJ78 series troopy 4.5L 1VDFTV V8 turbo diesel, VDJ79 series ute 4.5L 1VDFTV V8 turbo diesel

Our 4WD workshop can remove the old clutch as well as the flywheel to replace it with a new one. We can also do differential servicing as well to ensure your drivetrain is working efficiently.


Cel Fi Go signal booster installer in Sydney for 4WD vehicles


The Cel Fi Go signal booster was the last item that we had to install on this Landcruiser. Our workshop can install communication products from any brand to give your vehicle extra capabilities beyond using your mobile phone.

While there are different models of Cel Fi Go to choose from, the most popular is the Telstra Cel-Fi GO – 4WD Extreme Kit because it can maximise coverage when travelling or living in remote locations in Australia.

It can boost and distribute a 3G/4G mobile signal within your 4WD as well as support voice and mobile internet for more than one device. It means you have peace of mind knowing you will have a reliable signal. 

The packs normally include;

  • Telstra Cel-Fi GO Mobile Model
  • A 5G LTE Cellular Mobile Antenna – (698-960 MHz, 1710-2170 MHz, and 2300-2700 MHz)
  • 4G LTE Adhesive Panel Antenna with 3m cable
  • 12v DC Cigarette Lighter Power Plug with 5m Lead
this can then give you up to 100dB of system gain via Telstra’s Mobile Network that has the broadest coverage in remote areas. It will also work with Aldi Mobile, Boost Mobile as well as Woolworths Connect. The Telstra Cel-Fi GO will boost a single band at a time (either 3G 850 or 4G 700 or 4G 1800). 

Get 4WD accessories installed
on a Toyota Landcrusier 79 in Sydney


Here is another example of a Toyota 4WD getting upgrades and modifications to improve the performance outputs over the factory standard levels. Fitting aftermarket products or accessories to your 4WD can make it more suitable to your applications, especially if you are going to carry heavy loads, tow a boat or caravan. 

In this example the vehicle will be used for a combination of work as well as 4WD off road driving so it has to be reliable, powerful and bulletproof in all types of driving conditions. By upgrading key components like phone signal, engine, brakes, clutch, alternator and breathing capabilities you go a long way towards ensuring you never get stuck anywhere.

It doesn’t matter what you need our team can install any type of 4WD accessory on a Toyota Landcruiser or other brand of vehicle in our workshop in Sydney. 

We’d be happy to answer any questions about getting accessories fitted to your Landcruiser, we are available via eMail, phone or in our store in Narellan to provide advice, a quotation or bookings for an installation.
