Nissan 200SX Catalytic Converter S13 (1988-1993)

The Nissan 200SX S13 (1988-1994) catalytic converters fit mainly rear-wheel drive coupe models equipped with the following petrol engines:

• 1.8 Turbo CA18DT (166-171 hp, 1809 cc, 4-cylinder, 4 valves per cylinder, years 1992-1994)
• 1.8 CA18DE naturally aspirated (135 hp)
• 2.0 i 16V (140 hp, 1998 cc, years 1988-1993)
• Some variants including CA18DET/CA18DT (Euro 2 without OBD) and CG10DE/CGA3DE engines

These vehicles use petrol fuel, manual transmission, and hydraulic braking systems.

Catalytic converters for the Nissan 200SX S13 come in various OEM and aftermarket models, certified to meet Euro 2, Euro 3, and Euro 6 emission standards. They are available for both vehicles equipped with or without OBD systems. Typical dimensions range approximately from 165 mm to 760 mm in length, with weights from about 2.4 to 3.2 kg. Most are made with stainless steel construction and include vehicle-specific mounts.

These converters undergo stringent quality tests and meet emission compliance standards ensuring effective emissions reduction.

Yes, there are performance options such as sports catalytic converters designed for drift and tuning applications. For example, the DriftShop Sports Cat offers:

• 3" (76 mm) diameter metallic substrate
• 200 cells per square inch (CPSI) for improved exhaust flow
• Compatibility with S13 CA18DET engines
• Maintains minimal catalytic function whilst enhancing performance

These sports catalytic converters help to balance emissions compliance with increased exhaust flow for performance gains.

The factory-fitted CA18DET 200SX S13 models usually came equipped with catalytic converters, especially to meet emission standards such as Euro 2. However, some owners report that certain versions or markets might not have had them installed, which can affect MOT or emissions testing requirements.

To verify if your vehicle is equipped with a catalytic converter, inspect the exhaust system for a catalytic converter unit located downstream of the downpipe and upstream of the muffler.

When replacing a catalytic converter on your Nissan 200SX S13, consider the following:

• Ensure the replacement catalytic converter matches your engine specifications and emissions standard (e.g., Euro 2, Euro 3, Euro 6)
• Choose converters made from high-quality stainless steel with proper fitment mounts
• For vehicles equipped with OBD, pick an OBD-compliant catalytic converter
• Replace related components such as the Lambda sensor after 80,000 to 100,000 km for accurate emissions control
• Use only approved replacement parts to maintain legal compliance and vehicle performance

If you require technical support or compatibility verification, provide your vehicle VIN or original part number to ensure a perfect match.

Catalytic converters are crucial for reducing harmful exhaust emissions such as carbon monoxide (CO), nitrogen oxides (NOx), and hydrocarbons, helping vehicles meet regulatory standards like Euro norms. Properly functioning converters ensure your vehicle passes emissions tests and legal inspections.

• They do not significantly reduce engine power when OEM or quality aftermarket converters are used.
• Performance cats with optimized flow can slightly increase efficiency, particularly in turbocharged engines like the CA18DT.
• Using non-compliant or missing catalytic converters can cause your vehicle to fail emissions inspections and may be illegal in some regions, including California and the EU.

Maintaining a healthy catalytic converter also contributes to the longevity and efficiency of your exhaust system.

Common signs of a faulty or clogged catalytic converter include:

• Reduced engine power or acceleration
• Increased exhaust emissions or failed emissions test
• Unusual rattling noises from underneath the vehicle
• Illumination of the check engine light related to emissions
• Failed inspection or inability to pass an MOT

If you suspect an issue, have a qualified mechanic inspect the catalytic converter and exhaust system, including checking Lambda sensors and exhaust leaks. Replacing a faulty catalytic converter with a quality OEM or approved aftermarket unit is essential for emissions compliance and optimal engine function.
