Fatz TD42 Airbox Plumbing Kit suitable for Nissan Patrol GU

Fatz TD42 Airbox Plumbing Kit suitable for Nissan Patrol GU

This kit plumbs a Fatz Built 4″ GU airbox to the turbo on a TD42. Pick the kit that matches your turbo: the factory HT18, an upgraded turbo with a 3″, 3.5″ or 4″ inlet, or a high mount turbo with a 3″ or 4″ inlet. Fatz Fabrication builds every kit in Queensland and supplies the bends, pipe, hose and clamps to fit it.

The factory TD42 turbo sits in the low mount position. If your Patrol still runs its standard turbo, the factory turbo kit is the one you want. The high mount kits only suit engines where the turbo has been moved up onto a high mount manifold.

🚗 Suitable for:

• Nissan Patrol GU wagon and ute with a TD42, TD42T or TD42Ti engine
• Fitted with a Fatz Built 4″ GU airbox

📦 What’s Included:

• Factory turbo (HT18): 4″ to 3″ reducing 90 degree silicone bend, 3″ alloy pipe with a -8 fitting welded on, 3″ to 2.5″ reducing 90 degree silicone bend, -8 90 degree push lock fitting and 1/2″ hose for the PCV, -8 cap, and all hose clamps.
• Low mount 4″ inlet: two 4″ 90 degree silicone bends, long radius alloy 90 degree bend with the PCV fitting and an offset welded in, -8 90 degree push lock fitting, 1/2″ hose for the tappet cover vent, -8 cap, and all hose clamps.
• Low mount 3″ inlet: 4″ 90 degree silicone bend, long radius alloy 90 degree bend with the PCV fitting and an offset welded in, 4″ to 3″ reducing 90 degree silicone bend, -8 90 degree push lock fitting, 1/2″ hose for the tappet cover vent, -8 cap, and all hose clamps.
• High mount 4″ inlet: plumbing from the airbox to a 4″ high mount turbo inlet, with a JIC fitting welded into the pipe for the PCV, a 90 degree fitting, and hose to run to the tappet cover or a catch can.
• 3.5″ inlet and high mount 3″ inlet: plumbing from the airbox to the turbo inlet. Call us if you’d like the full parts list before you order.

🛠️ Fitment Details:

• Plumbs from the 4″ outlet of the Fatz Built GU airbox. It won’t fit the factory airbox.
• Check your turbo’s inlet size and whether it sits low mount or high mount before you order.
• On the low mount 3″ and 4″ kits, the alloy pipe has a kick welded into the turbo end to move it away from the exhaust manifold. Some trimming of the silicone bends may be needed.
• The low mount 3″ and 4″ pipes are finished in textured black powder coat to match the airbox.

⚙️ Why Choose This:

• Each kit is sized for one turbo inlet, so you aren’t buying reducers and couplings separately.
• The low mount 3″ and 4″ kits run a long radius alloy bend rather than a tight elbow.
• You can plumb the PCV hose back in or cap the fitting off.

📦 Dispatch Information:

❓ FAQs:

Q: Which kit suits a standard GU TD42?
A: The factory turbo (HT18) kit. The standard TD42 turbo is a low mount with a vertical inlet.

Q: Will this fit my factory airbox?
A: No. These kits are made for the outlet on the Fatz Built 4″ GU airbox.

Q: My turbo has been upgraded. Which kit do I pick?
A: Measure the turbo inlet (3″, 3.5″ or 4″) and check whether the turbo sits on a low mount or high mount manifold, then choose the matching kit. If you’re not sure, send us a photo and we’ll confirm.

Q: Do I have to plumb in the PCV hose?
A: No. The factory, low mount 3″ and low mount 4″ kits come with a cap to blank off the fitting.
