Fitment Notes

SR20DE Engine: WILD109 is designed for the 2.0L SR20DE DOHC 16-valve naturally aspirated engine used in the Australian N14 Pulsar SSS.

Australian N14 SSS: The N14 SSS was introduced in Australia in late 1991 and continued through 1995. It was sold as a five-door hatch and was available with both manual and automatic transmissions.

Not SR20DET: This listing is for the naturally aspirated SR20DE application and should not be confused with turbocharged SR20DET installations.

Because these vehicles are now over 30 years old, engines and exhaust systems may have been modified or replaced. Confirm the engine code and existing exhaust configuration before ordering.

What's Included

• 1 x Wildcat WILD109 header/extractor assembly

Gaskets, bolts and other installation hardware should not be assumed to be included unless specifically confirmed before ordering.

Recommended With

RBG109 – replacement header/manifold gasket.

Before installation, inspect the existing exhaust system, manifold studs, engine mounts and associated mounting hardware.

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the 2.0L SR20DE four-cylinder engine theoretically draws approximately 4,000 litres of intake air per minute at 100% volumetric efficiency and expels around 12,000 litres of hot exhaust gas per minute at approximately 600°C.

A well-designed header and exhaust system helps manage this high gas flow efficiently, reducing restriction and improving exhaust scavenging, torque, throttle response and engine performance.

Installation Tips

Before installation, confirm that the vehicle is an N14 Pulsar fitted with the naturally aspirated 2.0L SR20DE engine.

Lubricate threaded fasteners with WD-40 or a similar penetrating lubricant before removal to assist with easier removal and installation.

Professional installation is recommended. Check the condition and configuration of the existing downstream exhaust before installation.

After installation and several heat cycles, inspect the exhaust system for leaks and recheck accessible fasteners where appropriate.

Warranty & Compliance

Any catalytic converter, oxygen sensor and other emissions-control equipment required for the particular vehicle must remain correctly installed and operational.

Installation must comply with applicable Australian state or territory requirements relating to emissions, exhaust noise and vehicle modifications.
