The Peugeot RCZ 1.6 C, a sleek and sporty coupe, relies heavily on its turbocharged engine to deliver a dynamic driving experience. 

At the heart of its performance lies a precision-engineered turbocharger system, designed to optimize power output and fuel efficiency. 

This article explores the technical specifications, compatibility, and functionality of turbocharger part numbers 53039700243, 53039880217, 

53039700179, 0375N7, and 9807682180, which are critical components for maintaining or upgrading the RCZ 1.6 C’s powertrain.

1. Overview of Turbocharging in the Peugeot RCZ 1.6 C

The 1.6-liter THP (Turbocharger High Pressure) engine, co-developed by PSA Peugeot Citroën and BMW, 

is a 4-cylinder powerplant renowned for its balance of performance and efficiency. 

Turbocharger  play a pivotal role in this engine by compressing intake air, allowing more oxygen into the combustion chamber. 

This process boosts horsepower (up to 156–200 HP, depending on tuning) and torque (240–275 Nm) while adhering to modern emission standards. 

The OEM-designed turbocharger ensure seamless integration with the engine’s direct injection system and variable valve timing.

2. Key Turbocharger Part Numbers and Their Roles

a. 53039700243 & 53039700179

These part numbers represent turbocharger assemblies specifically engineered for the 1.6 THP engine family. 

They feature:

• Dual-Scroll Turbine Design: Reduces turbo lag by separating exhaust pulses, improving low-RPM responsiveness.

• Integrated Wastegate: Regulates boost pressure (up to 1.2 bar) to prevent overcharging.

• Water-Cooled Center Housing: Enhances durability by mitigating heat stress during high-load conditions.

These units are direct replacements for factory-fitted turbos, ensuring compliance with Peugeot’s performance and emissions standards. 

Compatibility extends to RCZ models produced between 2010–2015.

b. 53039880217

This part number denotes a revised turbocharger variant addressing common wear issues in earlier models. 

Key upgrades include:

• Reinforced Turbine Blades: Manufactured from Mar-M247 superalloy to resist thermal fatigue.

• Revised Oil Feed System: Improves lubrication to extend bearing life, a known failure point in high-mileage engines.

• Enhanced Sealing Gaskets: Reduces the risk of boost leaks at elevated pressures.

c. 0375N7

Identified as an aftermarket reference, 

this turbocharger is compatible with the RCZ 1.6 C and offers:

• Ball Bearing Core: Reduces friction for faster spool-up compared to traditional journal bearings.

• Billet Compressor Wheel: CNC-machined for precise airflow characteristics, improving mid-range torque.

• Universal Fitment: May require adapter plates for non-OEM installations.

d. 9807682180

This part corresponds to a turbocharger repair kit, including:

• Replacement gaskets and seals (Viton-coated for heat resistance)

• Locking nuts and bolts (torque-to-yield specifications)

• Thrust collar and piston ring assemblies for rebuilding worn units

3. Technical Specifications

• Compressor Wheel Diameter: 42mm (inducer) / 56mm (exducer)

• Turbine Housing A/R Ratio: 0.48 (optimized for rapid spooling)

• Maximum RPM: 220,000

• Operating Temperature Range: -40°C to 1,050°C

• Oil Viscosity Requirement: 5W-40 synthetic meeting PSA B71 2290 standards

4. Performance Advantages

• Power Delivery: Turbocharger spool initiates at 1,400 RPM, delivering 90% of peak torque by 1,600 RPM.

• Fuel Efficiency: Maintains 6.2–7.1 L/100km under mixed driving conditions.

• Emissions Compliance: Meets Euro 5 and Euro 6 norms via precise boost control.

5. Installation and Maintenance

Installation Notes:

• Always replace the oil feed line and coolant hoses during turbocharger replacement.

• Prime the turbocharger with oil before initial startup to prevent dry bearing wear.

• Use a calibrated torque wrench (tightening specs: 25 Nm for housing bolts, 45 Nm for manifold nuts).

Maintenance Schedule:

• Oil changes every 10,000 km with PSA-approved lubricants.

• Boost pressure checks every 30,000 km using OBD-II diagnostics (target: 0.8–1.0 bar at idle, 1.2 bar under load).

• Inspect intercooler piping for cracks biannually.

6. Common Failure Modes and Solutions

• Oil Coking: Caused by infrequent oil changes. Solution: Install turbo timer for proper cooldown.

• Wastegate Actuator Sticking: Diagnosed via erratic boost readings. Clean linkage with carburetor cleaner.

• Compressor Surge: Often due to aftermarket air filters. Revert to OEM airbox or install blow-off valve.

7. Upgrading Considerations

For enthusiasts seeking beyond factory performance:

• Hybrid Turbos: Combine 53039880217’s housing with a larger compressor wheel (requires ECU remapping).

• Ported Exhaust Manifold: Reduces backpressure for 5–8% power gains.

• Thermal Wrapping: Lowers underhood temperatures by 40°C, preserving turbo longevity.

8. Compatibility Verification

Confirm fitment using Peugeot’s VIN decoder or cross-reference tables. Critical parameters:

• Engine Codes: EP6CDT (156 HP), EP6CDTX (200 HP)

• Transmission: Both 6-speed manual and 6-speed automatic variants

• Model Years: 2010–2015 (pre-facelift), 2015–2018 (post-facelift with revised ECU)

9. Environmental and Regulatory Impact

These turbochargers incorporate:

• Recyclable aluminum housings (85% post-industrial content)

• Low-friction seals meeting REACH SVHC compliance

• Reduced particulate emissions via optimized combustion phasing

10. Market Alternatives and OEM Validation

While aftermarket options exist, Peugeot-approved turbos (530397xxxxx series) undergo:

• 500-hour dyno endurance testing

• Leakage checks at 2.5x operating pressure

• X-ray inspection of castings for micro-fissures
