Why Rebuild a Car Turbocharger?

For performance enthusiasts and everyday drivers, a failing turbocharger means power loss, poor fuel economy, and potential engine damage. Many repair shops will tell you to replace it, but a high-quality rebuild offers OEM performance at a lower cost.

At Turbo Doctor, we restore car turbochargers to factory condition, using our Leonardo cleaning system and Synthesis high-speed balancing machine for precise, reliable results.

Step-by-Step Turbo Rebuild Process for Cars

1. Turbo Disassembly & Damage Assessment

Every turbo is disassembled, and key parts like the compressor wheel, turbine shaft, and housing are inspected for wear.

Common car turbochargers we rebuild:

✅ Volkswagen/Audi 2.0T (BorgWarner K03)

✅ Subaru WRX FA20 (IHI VF52)

✅ BMW 335i N54 (Mitsubishi TD03)

2. Deep Cleaning & Component Replacement

Using our Leonardo system, we remove carbon buildup, oil residue, and contaminants. We replace bearings, seals, and gaskets with OEM-quality parts for long-term durability.

3. Turbo Balancing for Performance & Reliability

A car turbo spins at up to 250,000 RPM, meaning even a slight imbalance can lead to failure or poor performance. Our Turbo Doctor Synthesis machine ensures:

✅ Ultra-precise balancing for zero vibration

✅ Peak boost efficiency for maximum power

✅ Extended turbo lifespan

4. Final Testing & Quality Control

Every rebuilt turbo undergoes:

🔹 Vane flow calibration for optimal airflow

🔹 Performance testing to ensure OEM-level boost delivery

🔹 Leak & pressure tests to confirm perfect sealing
