Nissan Patrol TD42 Split-Pulse Exhaust Manifold – LOW MOUNT FACTORY REPLACEMENT

TD42 Split-Pulse Exhaust Manifold. Constructed from SiMo Ductile iron – FACTORY REPLACEMENT STOCK TURBO POSITION.

Our TD42 Split-Pulse Exhaust Manifold fits all GQ/GU TD42 engines (Silvertop or Blacktop). Retaining the low-mounted turbo position exactly the same as a factory Nissan exhaust manifold.

IMPORTANT NOTE: This manifold is a direct factory replacement – OEM/STOCK Location

Although the turbo position is in the factory location, there is significant design differences in the internal structure of the manifold to smooth the flow paths and merge the ports together as smoothly as possible.

A split pulse exhaust manifold will provide more drive energy to the turbine over conventional merge-type manifolds of an equal design. The larger thermal mass with thicker walls and more material around critical areas also provides better heat retention of the exhaust gas while it travels to the turbine.

The more heat that can be retained from the combustion event and well directed by the use of the split pulse design, the more energy that can be delivered to the turbine. For a given amount of fuel, this will equate to better efficiency, a faster-spooling turbocharger, and more power and torque on any given setup.

For those looking to use an external wastegated turbocharger please see our forward position lowmount turbo manifold here –> https://www.tillix.com.au/product/nissan-patrol-td42-split-pulse-exhaust-manifold/

A pressed stainless steel turbine inlet gasket and a choice of steel or Inconel 625 exhaust to turbo studs will be provided as per the order. Both come with 316 Grade stainless steel washers and copper coated German made WURTH prevailing torque lock nuts.

An Inconel 625 stud kit for fixing the manifold to the head can be purchased separately here
https://www.tillix.com.au/product/inconel-exhaust-manifold-stud-kit-td42-patrol/

Or, you can specify the Inconel stud mounting kit with the manifold as you add it to the cart.

Each manifold comes with the choice of a Raw cast finish. Or HPC Extreme Temp black performed right here in Brisbane by Thermal Edge Coating > http://www.thermaledgecoating.com.au/

If you prefer silver or other types of coatings please contact us prior to order for lead times on these.
