PDI Front Mount Intercooler Kit suitable Nissan Patrol GQ TD42

PDI Front Mount Intercooler Kit suitable Nissan Patrol GQ TD42

At PDI we recognise the GQ has a great following in the 4WD market due to them being a solid drivetrain and lots of modifications to make them a serious contender in the offroad scene.

The GQ Nissan Patrol TD42 PDI Front Mounted Intercooler kit benefits from extensive development on other models and demonstrates PDIs focus on produce the biggest and most efficient designs for each vehicle they develop.

🚗 Vehicle suitability, 

• Nissan Patrol GQ TD42 Engine with Factory GU style or aftermarket Turbo Kit 1988-1999

Kit Options:

• Aftermarket Turbo: Suits UFI, GTurbo, and all other aftermarket turbochargers in a similar configuration.
• Factory Turbo with 3-bolt flange: An extra Adaptor is included to connect the factory GU style Turbo

🧩 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.

📦 What’s in the Kit,

• Brackets for mounting the intercooler with additional bolts
• Intercooler with 595 x 330 x 76 mm core, capable of supporting as much power as your TD42 can produce.
• Works with the factory air conditioning system in place.
• Fully cast alloy end tanks with recesses to allow it to sit back and maintain the factory look.
• Stainless pipe (polished) 2.5”
• Adapter to bolt onto the intake manifold.
• Black silicon 6mm thick with 5 layers for maximum longevity.
• USA made high torque liner clamps.
• Mild steel brackets – zinc plated and then painted black – no stainless brackets which are prone to fatigue crack and cause rusting of body panels due to anode/cathode reaction.
• Screw in oil drain on bottom of intercooler.

This is a very popular kit, due to its effective and efficient design and you will find lots of positive feedback on many forums from owners.

🗣️ What Customers Say,

• Ben- “Picked one up after noticing a crack in my standard intercooler. Huge improvement in EGT’s, I was worried it was going to cause my TD to run hotter but it’s had the opposite. Runs about 4c cooler. Love it”
• Jesse – “Was good to find a bolt on kit I could fit myself. Instructions were straight forward, still fit with my winch bar, works really well.”

🔧 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.

The end result is an intercooler that will reduce intake temps to a minimum to maintain the performance only normally seen on cold days when driving unloaded. The increase in Mass air density will also allow more fuel to be added safely without risking excessive EGT. We would expect your EGT to drop 50-100deg.

💡Will large spotlights affect the results?

This is a common question, and important question.

• We have many owners who regard these as the best unit they have fitted with their ability to provide cool inlet air. That is after trying top mounts and smaller front mounts.

• When tuning on the dyno we don’t have a large cooling fan in front so this simulates zero speed, high load situations with the only air being pulled through by the main engine fan.

• For most the alternative is an electric thermo fan attached to a top mounted intercooler. They are working to overcome the heat rising from the engine and from the cores close proximity to the hot engine. The insulation in a electric motor is rated to a certain temperature and the best quality units will switch off when they get to 130degC to protect themselves. Instead of assuming them to be at their best when you need them the most, on a hot day under high load, you need to expect to have zero intercooler efficiency.

• Front mount exposure compared to the opening in a bonnet scoop is significantly different. The placement is important as airflow over the bonnet into a scoop can be disrupted by bull bars and lights. Also some engine bays are positively pressured due to air hitting the front diff and other components – this means, just like your radiator, the best place to get cool air is at the front of the car.
