PDI Front Mount Intercooler Kit suit Landcruiser HDJ100 / 105 Series Mk2

Why Front Mount Beats Top Mount

Top mount intercoolers are popular due to ease of installation and bonnet scoop aesthetics but they simply can’t match the performance of a properly designed front mount.

A front mount intercooler delivers:

• Better cooling at both low and high speeds
• Consistent airflow regardless of driving conditions
• Lower intake temps and improved engine efficiency

Brake Booster Upgrade

PDI have the best brake booster upgrade on the market for the 105 series. Unlike the factory unit, it is dual diaphragm, but we have also increased the diameter of the booster to increase surface area and effectiveness. This has allowed many 105 series owners to be able to lock up their brakes on systems where it was otherwise impossible. Our booster increases 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. They can be purchased HERE

EGT Gauge.

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 an 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. These can be purchased HERE

Optional Transmission Cooling Upgrade

For automatic vehicles, PDI offers a high BTU transmission cooler upgrade, mounted neatly in front of the intercooler using custom brackets. This ensures your transmission stays protected under heavy load without compromising intercooler performance.

Designed for the HDJ100 with no modifications to the air conditioning system or overflow reservoir. If you have a 105 and would like to fit the large core, then the hose and piping from the condenser to the compressor needs to be replaced with the recessed HDJ100 setup, or purchase a one piece replacement from us.

For 105’s running the 1HZ engine we suggest our smaller core (645x240x65) to reduce the heat loading on the radiator. 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 in front of 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.

The early 100 series didn’t have any power steering cooler pipes out front and most owners leave it like that. If you have or want to maintain the power steering pipe cooler, this needs to be routed through the opening for the passenger side headlight.

A crossover delete option is available (extra $150) for the 1HD-FTE.

All 1HZ / 1HD-T / 1HD-FT are crossover delete design as standard and at no extra fee.

CROSSOVER DELETE OPTION

For the 1HDFTE, PDI give the option of leaving the crossover in place (with the EGR valve) or a cast alloy adapter onto the inlet manifold for all of the cruiser models (80/75/79100/105).
The 1HDFTE in our HDJ79 ute has the crossover in place and has 311rwkw and 1000nm (at the wheels). I’m sure there is a point where air flow is better without the crossover but I don’t believe we are there yet.
Leaving the crossover in place is good for:
1. Legally it has to be there since the EGR valve is in the crossover, you can still stop EGR gas flow with the valve in place.
2. No more power is made by removing the crossover (for most people)
3. Smooth shutdown is possible with the crossover and butterfly in place.
4. If the engine ever runs on its own fumes (and I’ve seen two FTEs do that) then turning off the key turns off the engine.
5. If it’s the late model with electronic butterfly then it must remain plugged in to the harness.
6. If you need to pass a pit inspection the crossover must be fitted.
