The 1VD V8 4.5L common rail turbo diesel engine in the current 70 Series Landcruiser has forged itself a reputation as a tough off-roader, with truck-like power and a fantastic amount of torque right from the word go. Off the factory floor, the Landcruiser is shackled by the very restrictive standard Toyota exhaust.
With the standard exhaust going as small as 1 & 7/8″, and running through a diesel particulate filter (DPF) and baffled muffler, the sound of the V8 motor is nowhere to be heard. The fitment of a Manta 3″ exhaust system changes all that! Running full 3″ piping, right from the either the turbo face or the DPF, to the tail, it’s available in a number of configurations, so you can have an exhaust note close to the factory level, go all out with a wild, unmuffled V8 bark, or find a happy medium somewhere in between.
For the ultimate in looks and sound, we now also have our twin 3″ tailpipe version available. If you’ve already got a Manta exhaust, this is available as a simple bolt-on to your existing exhaust system!
Finally, our long-awaited 4″ system is also now available! This is our Extreme version, offering the loudest possible note, and maximum flow.
Replacing the standard exhaust with a 3″ version has a number of benefits, including reduced turbo lag, improved peak power and torque, greater responsiveness, and reduced fuel consumption. On average, we see a 15% gain in power, and around 1 – 2L per 100km reduction in fuel consumption (with a full exhaust and tune).
The full 3″ exhaust is consistently rated as the best performance modification to carry out on the V8 Landcruiser, not only due to the glorious sound it releases but also for the massive improvement in driveability. Many dealers are fitting them on brand new vehicles – don’t spend another day without one!
DPF BACK OR TURBO BACK?
The latest model Landcruiser comes from the factory with a Diesel Particulate Filter. These are an emissions device designed to control the amount of soot emitted from the exhaust system. We have two options in our exhaust range – DPF back (similar to a “cat back” system on a petrol vehicle), or turbo back (replacing the entire factory exhaust system, including the DPF).
The turbo back system does require a recalibration of the vehicle’s Engine Control Unit (ECU) to remove certain functions associated with the DPF system. This is intended for off-road or race use only.
Based in Canberra, Garage76 are your complete 4WD and Diesel Performance Tuners. From basic upgrades, to complete pre-registration vehicle builds, we have the knowledge and products to build, maintain & repair your ultimate diesel 4wd.
WE OFFER THREE STAGES OF DIESEL PERFORMANCE PACKAGES
From a safe and reliable tune of your OEM ECU through to wild diesel performance upgrades, we've got 20+ years of diesel tuning under our belts and can tailor a package to suit your performance or touring needs.
Our Stage One kits (vehicle depending) will always include an ECU remap and a tune on our in-house dyno.
No two vehicles are the same and every diesel performance package we book spends time on our dyno.
G76 Custom ECU Remap
Once you are looking to go beyond the performance of our basic Stage 1 Package, you will reach the limitations of your factory turbocharger. At this point a turbocharger upgrade will be required, along with appropriate upgrades to the exhaust, air intake system and intercooler. With these upgraded items we are able to squeeze more performance than a stock setup will ever provide.
G76 Custom ECU Remap
Upgraded Snorkel & Airbox
Intercooler Upgrades Or Intercooler Fans
Looking for maximum GRUNT without compromising factory reliability? Our Stage Three Package is for you! This package will give you the ultimate in diesel performance, with massive gains available in power and torque.
The main difference between our Stage Two and our Stage Three Package is the addition of high flow fuel injectors. In a diesel engine, more fuel = more power, provided you have the air to burn it! We also only have a small window of crankshaft rotation available to inject the fuel. High flow injectors allow us to increase the amount of fuel delivered to the engine during this window, resulting in huge gains in power and torque.
*power and torque numbers will differ between vehicle models and final diesel performance packages and tunes. Our increase numbers should be used as a guide only. Different vehicle makes will have variations in the packages we offer, not all packages come with intake cleans.
