HP Diesel - Nissan Navara D40 ST-X V6



The Navara and Pathfinder STX 550 is a powerhouse in its own right with a 3.0ltr V6 Renault-built V9X motor putting out 170kw at the flywheel from the factory.

Shortly after the release of this vehicle, a very apparent problem arose. The factory intercoolers would split away from where the end tanks would be pressed together with an o-ring between or crack the core within the first 100000kms causing boost leaking issues. On further inspection, we found the factory intercooler to also be majorly restrictive and under-engineered.
We set to deliver a solution to this problem and the HPD V6 Navara intercooler kit was born.

We designed a huge 600x300x76mm front-mounted bar and plate core and wrapped it with 2 cast aluminum end tanks. Not only is this core going to have amazing thermal efficiency but the free-flowing nature of an HPD core removed the restriction issue of the factory intercooler.

Laser-cut brackets and gussets were then TIG welded to the end tanks along with a billet CNC machined MAP sensor mount so that this cooler can be installed directly back on to the factory mounting points. Large aluminum mandrel bent piping was then added to compliment the quality and design of the rest of the intercooler kit.
Last we designed a Billet aluminum turbocharger adaptor to connect the whole kit to the factory turbo compressor housing.

This kit's stunning looks are perfectly complemented by its superior performance and quality of build and we are confident you will agree.
Although Intercoolers will support cold charge air allowing a vehicle to be tuned to a higher power spec, rarely do they instantly produce detectable power with no other performance modifications or tuning. Well, this kit will unleash up to a massive 11kw+ of power and even more with supporting modifications like exhaust and remap tuning.

Kit features:

  • Bar & Plate Core 600x300x76mm
  • Alloy mandrel bent piping
  • Quality silicone hoses
  • German-made load rated hose clamps
  • Billet alloy turbo adapter
  • Hot side piping 57mm
  • Cold side piping 63mm
  • 1/8 BSP boost reference point
  • Integrated laser cut TIG welded mounting brackets
  • Direct fitment to stock mounting points
