PDI Landcruiser HZJ105 105 Series Front Mount Intercooler Mk2 1HZ series core
From $1,700 Incl GST
All intercooler kits are designed, made and shipped by PDI in WA.
PDI have the largest and most efficient intercooler for the Landcruiser 100 / 105 Series. For the 1HZ powered 105 we suggest our smaller core, which is more efficient than our competitors. The core size is 645x240x65 and is better placed for increased cooling without limiting flow to the condenser and radiator. With this core we have designed the end tanks to work around the air conditioning line on the drivers side.
It is hugely important to keep your EGT (Exhaust Gas Temperatures) low in a 1HZ as high combustion temperatures will cause cracks in the piston and head. This is achieved with reduced intake air temperatures, which results in improved performance.
The PDI Landcruiser 100 / 105 Series Front Mount Mk2 intercooler significantly raises the bar for what can be achieved. Now with factory turbo engines pumping out +300rwkw, we have the intercooler that is the clear choice for such a setup.
Our intercoolers fit with all bull-bar and winch designs as the core is set back to get more draw through from the main engine fan. The fitting of thermo fans may be required for other brands where the intercooler is located too far forward and there is no draw through or ramming of air from the front since the bullbar and other items are in the way.
Please note: Intercooler kit for auto trans comes with brackets for OEM transcooler.

More Info:
Intercooler pipes: 2.5” stainless steel with heavy duty silicon joiners. Silicon selection now simplified with no silicon in front of the front panel.
High torque stainless steel clamps.
The moulded end tanks with rear facing outlets have enabled a bigger core, then we pushed it back as far as possible to increase the draw through from the engine cooling fan. With the outlets being rear facing, the stainless steel pipes are connected to the intercooler with straight silicon.
While it is not as effective as our larger core, most 1HZ aren’t pushed too hard and this core will easily cater for almost all turbo 1HZ builds. This core is designed to fit around the condenser pipe.
Air can be felt strongly pulling through the intercooler 50-80mm from the core, while idling on startup. To continue to have the air being pulled through while engine temps are low (and the fan hub normally free wheels) some extra fluid can be added to the viscous coupling.
All 1HZ/1HDT/1HD-FT are crossover delete design as standard and has no extra fee.
EGT Gauges
If you plan to install an EGT probe, we recommend doing this into the dump pipe after the turbo. Recently we have decided to stock a budget EGT probe system that uses a Class A probe with 2m long lead and digital display making it easy to read and mount. We have another option in green that has a smaller thread for mounting into intake air temps if you wish to see how you system is performing.
Brake Booster Upgrade
PDI have the only brake booster upgrade on the market for the base spec 105 series that have the non-ABS systems. The factory booster is a small single diaphragm unit which is insufficient in when towing or when wheel size is increased. The PDI upgrade for the 105 is a dual diaphragm unit with larger than standard diameter giving an increase in the mechanical advantage able to be applied to the master cylinder by 50% and has transformed the vehicle for many 105 series owners.
Upgraded Airbox
Typically we suggest this mod is cost-effective if you have a 12mm pump and are running higher flow injectors with more than 160kw at wheels. PDI have their own design airbox that is cast aluminium, uses a 200 series panel filter and has stainless steel latches to hold the lid down.
