4WD Modifications - Powertrain
Extracting more power and torque, engine swaps, rebuilds and fuel issues are all covered.
WIDE-TRACK, HEAVY DUTY LANDCRUISER REAR AXLE
Dana has come up with a replacement axle for V8 70 Series Toyotas.
This new Dana 60 axle variant could be the solution to the Toyota 70 Series' narrow-rear-axle-track problem.
DON'T 'SOCK' YOUR SNORKEL
Think about what's happening and you won't want to do it - August 2016
There's a current craze for fitting a plain or oily-foam 'sock' over a snorkel. It may seem like a good way of keeping your air cleaner element dust-free, but it isn't.
iDRIVE PERFORMANCE ENHANCER
A plug 'n' play way to improve accelerator pedal response - December 2016
Among the myriad products that we get to test here at Outback Travel Australia a stand-out product arrives occasionally. Our first impressions are that iDrive is one of those products.
LEAVE YOUR COMMON-RAIL DIESEL ENGINE ALONE
It's tempting to fiddle with turbo-intercooled diesels, but we suggest not - August 2016
Boys love to play around, don’t they? They buy a perfectly good vehicle and can’t help wanting to ‘tweak’ it.
LPG + DIESEL = MORE POWER + IMPROVED ECONOMY?
'Torque-topping' a diesel needs to be done with caution
Introducing Liquid Petroleum Gas (LPG) into the intake air of a diesel engine isn’t a new idea, but electronically-controlled systems for doing this ‘fumigation’ job are relatively new in Australia.
LPG IS THE PRINCIPAL ALTERNATIVE 4WD FUEL
Forget hydrogen, fuel cells and electric 4WDs in the short term.
Constant hikes in the price of fuel have spurred many petrol-fuelled 4WD owners to look for ways to reduce their bills. LPG is the best current option.
NO MAGIC WAND TO IMPROVE FUEL ECONOMY - November 2015
Nearly all 'fuel saving' gadgets don't work - it's as simple as that.
The USA’s Environment Protection Agency (EPA) has concluded a series of scientific tests on a wide variety of devices and additives that are claimed to improve fuel economy. Of the hundreds tested, very few actually reduced fuel consumption.
You’re happy with your 4WD, but you feel that it could be even better - July 2016
There are two approaches to improving 4WD engine performance: ‘hotting up’ the existing engine or repowering the vehicle. Both methods have their advantages and disadvantages
PORTAL AXLE KITS
Locally engineered axle mods for increased clearance.
Portal hubs feature on many high ground clearance military-type machines, including the Mercedes-Benz Unimog. You can have these fitted to your LandCruiser ute, but they're not cheap.
PREVENTING FUEL SYSTEM WATER DAMAGE
Water in fuel is common and can cost you thousands.
We've used various types of water separators in all our 4WD vehicles and the latest we've bought is the best so far.
EXHAUST SYSTEMS FROM REDBACK - September 2015
A replacement system that is made better and breathes better.
In 2012 the Redback Extreme Duty project began, with the goal of making the toughest bolt-on 4WD exhaust systems available anywhere in Australia. After having a 2015 system installed on one of the OTA Team vehicles, we reckon the project has been a success.
RE-ENGINEERED SAFARI SNORKEL RANGE
The best-known snorkel range just got better - May 2016
Safari has re-engineered its product lineup, dividing the existing snorkel range into two separate product lines and adding a new line of high-flow, performance snorkels.
REFURBISHING THE OLDER DIESEL ENGINE
There may be life in the old girl yet
Older diesel powered 4WDs have a great deal of appeal for serious bush travellers. Pre-emissions engines have no electronics, no computers and no exhaust gas recirculation.
THE FUTURE FUEL IS BIODIESEL
Australia's long term plan is for more biodiesel.
The Treasury modelling for Australia's fuel future is heaviliy based on biodiesel, not natural gas or LPG.
TJM AIRTEC SNORKEL RANGE EXPANDS
The custom-designed Airtec range suits more new 4WDs - December 2016
A snorkel is often the first accessory fitted to a four wheel drive. A snorkel is essential for deep water crossings and can reduce the amount of dust that gets to the air cleaner element, extending its life.
TRU TRACKER WIDE-TRACK KIT FOR LANDCRUISER 70s
An engineered fix for the narrrow rear track on V8 LandCruiser 70 Series.
The Multidrive Tru Tracker rear track correction system for the V8-powered LC79 and 78 Series widens the track of the rear axle so that it matches the front.
