PDI GU Front Mount intercooler Kit suitable for Nissan Patrol Series 4 GU ZD30 CRD
PDI developed their new generation intercooler kit for the GU Patrol with an updated core design to give better clearance around the bull bar mounts and sat back further.
🚗 Vehicle suitability,
- Nissan Patrol GU Series 4
- ZD30 Engine ONLY
- Patrol Series 4 from October 2004 to 2016 – PDI kit suitable for all Nissan diesel engines.
For TD42 – See this listing – HERE
It was also much bigger – around 40% larger frontal cross-sectional area than a “standard” 600x300mm core.
🧩 Fitment,
- 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 ZD30 CRD.
💥For the ZD30 Owners,
- The ZD30 has always been highly strung from the factory with rich air fuel ratios and relatively low boost they exhibit very high EGT.
- It’s the only turbo I’ve seen with a glowing turbine housing on the dyno in stock form.
- Once pushed a little harder the top mount design isn’t effective.
- The ZD30 kit will feature 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. A port is located on the pipe, before intake for connection to the MAP sensor.
🔧 Testing, and why you SHOULD NOT use a top mount intercooler for your rig,
- If considering the purchase of a top mount intercooler then you need to consider the results compared to our Landcruiser 80 series Front mount PDI front mount kits.
In back-to-back testing, the PDI front mount kit dropped inlet temps from 260°C to 70°C at 100km/h uphill with 40+ psi. Outperforming top mount setups by a wide margin. Here’s some results compared to the best aftermarket top mounts on the market (when tested on a VDJ79 Toyota Landcruiser V8):
Factory Top Mounted Intercooler: 88°C
Upgraded Top Mount Intercooler: 75°C
PDI Front Mount Intercooler: 47°C under identical condition – even dropped EGTs by 50°C at 110 km/h – proven protection and power.
That makes the PDI Coolers front mount 3 times more effective than the aftermarket upgrade.
🚗 Auto Trans? No problem.
- If you have an auto transmission we offer a heavy duty transmission cooler with brackets to mount in front of the intercooler.
- If you need to run a thermo-fan and have a auto transmission, then we would suggest it is better to run a smaller, square shaped transmission cooler on the passenger side and the thermo-fan on the drivers side.
🧊 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.
- It means that the cooler side of the intercooler will allow cooler air to pass through and help with air conditioner condenser function.
- Our intercooler has 2 lugs on the top and 2 lugs on the bottom to Thermo fan mounting easier.
- If running aftermarket thermo fans we highly recommend SPAL fans from Italy.
🧩 Fitment Notes:
- The Hot-pipe in this kit is suitable for both high and low mounted turbos.
- If you have a high mounted turbo, the Hot-pipe supplied will have some extra length on it to be trimmed. Installers typically trim the stainless section down and change the orientation of the silicon to connect to the intercooler.
- The standard hot side piping has a 90deg silicon rescuer to go onto the turbo in the low mount configuration.
