PDI Front Mount intercooler Kit suit Nissan Patrol Series 4 GU ZD30 CRD/DI/TD42

Patrol Series 4+ Wagon (not ute) from October 2004 to 2016 – PDI kit suitable for all Nissan diesel engines.

Patrol Series 4 ute (not wagon)up to 2006 will need to order the series 1-3 kit due to running that series bonnet and radiator support panel

PDI developed their new generation intercooler kit for the GU Patrol with an updated core design which gave better clearance around the bullbar mounts and sat back further. It was also much bigger – around 40% larger frontal cross-sectional area than a “standard” 600x300mm core. The extra large core is 675 x 370 x 76 and is ideal for those needing the best intercooling for maximum efficiency gains.

A smaller intercooler is ample for many customers who need a step above a top mount intercooler, so raised the bottom of the core 110mm (core dimensions 675 x 260 x 76). This design gives additional clearance to all bullbar and winch installs.

Both of the above designs use the same intercooler outlet locations, but different piping for the TD42 or ZD30 CRD.

NOTE: For all single cab ute need to order the series 1-3 kit, since even the series 4 utes kept the series 1-3 front end

The ZD30 has always been highly strung from the factory with rich air fuel ratios and relatively low boost they exhibit very high EGT. This is the only turbo I’ve seen with a glowing turbine housing on the dyno. Once pushed a little harder the top mount design isn’t effective.

The ZD30 kit features 2 1/2″ stainless pipework to and from the intercooler with the stainless necking down to 2” to roll over 180deg and line up with the turbo outlet. This means no elbows coming off the turbo getting blasted with a constant flow of hot air. Our silicon joiner here now has an oil resistant coating. Piping on turbo side briefly goes through the wheel arch but is in stainless so is very unlikely to get damaged. The inlet side piping is also 2.5” stainless and has a joiner in the middle. Two ports are located on the pipe, before intake for connection to the MAP sensor.

The TD42 has long been a favourite and with the appropriate mods, can be a solid performer. Our front mounted intercooler will maintain cold day driving performance. We also run through the very front of the passenger side wheel arch area and into the engine bay. Connection to the turbo can be fun as there are many different turbo setups and orientations people run. We can supply an adapter to bold to the factory turbo outlet. The intake side has three parts with the top one being an intake adapter that bolts to the manifold. This adapter has a 1/8”NPT port with brass barb for a boost source.

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 GU. 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 GU 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 GU owners. This can be purchased by clicking 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

Auto Transmission Cooler Options

If you have an auto then by selection the auto option we will supply the standard kit with one for he best transmission coolers on the market (rated at 45,000BTU) and brackets that bolt to the intercooler with a series of holes that allow it to be located at three different heights. The lowest height places it down so only partially covering the bottom of the intercooler.

If you choose to use the original (factory) transmission cooler then you will need to fabricate some brackets and we recommend placing it on the passenger side in front of the hot side of the intercooler. This means the intercooler still has a really good chance to cool the intake air from air heat extracted from the transmission.

Thermo fan mounting

Following from above for auto with factory transmission cooler or if running a manual gearbox, this gives room to place the thermo fan on the drivers side which means any air pushed through may add to intercooler efficiency, but it means that the cooler side of the intercooler will allow cooler air to pass through and help with air conditioner consdenser function. Our intercooler has 2 lugs on the top and 2 lugs on the bottom to make Thermo fan mounting easier. If running aftermarket thermofans we highly recommend SPAL fans from Italy.
