VAG 2.0 TFSI K04-64 Hybrid Turbo Stage 1 | 370-390 HP

Serious Performance Upgrade

For owners of the Audi S3, Leon Cupra, or Golf R, the factory K04-64 is a capable unit, but it quickly reaches its flow limit when pushing for higher stages. Our Stage 1 Hybrid reimagines this platform by integrating internals typically found in the later IS38 units, combined with bespoke machining. This allows for significantly higher boost ceiling and airflow capacity without the lag associated with large frame universal turbos. It is the perfect balance for a fast road or track-day weapon.

Why This Turbo Wins

• Faster spool and improved transient response
• Stronger mid-range torque delivery
• Increased top-end airflow (up to 390 HP)
• OEM-style bolt-on fitment
• Reinforced 360-degree thrust bearings
• Precision balanced for high-RPM stability

Internal Upgrades

• Billet CNC Compressor Wheel: Larger, lighter, and more efficient than the cast original.
• Custom Lightweight Turbine Wheel: Reduced rotational mass for lightning-fast spool.
• Reinforced Bearings: Upgraded to handle higher boost pressures and increased thermal loads.
• Machined Housings: Precision-profiled to accommodate the larger aero components.
• Plug & Play Fitment: Uses standard oil and water lines for a seamless installation.

Performance Characteristics

This Stage 1 Hybrid is tuned for a “punchy” driving style. Thanks to the lightweight turbine wheel, low-RPM response remains nearly identical to stock, while the enlarged CNC compressor wheel allows the turbo to hold boost much further into the redline. Expect a violent mid-range pull and a much wider power band that transforms the 2.0 TFSI into a genuine supercar-killer on the highway.
