Genuine Garrett Stage 1 Premium Hybrid Turbocharger built using 7+7 blade Billet Wheel, based on stock Garrett GTD1449VZturbocharger from VAG`s engine 2.0 TDI CUNA, CUPA is the ultimate choice for Seat Leon 5F, Skoda Octavia III, Audi A3 8V and VW GOLF VII for someone looking for a fast daily driver.

The full list of changes applied is as follows:

– Journal bearings – so-called ‘360’,
– Modification of compressor housing,
– Modification of seal plate,
– Enlarged compressor Billet Wheel 7+7,
– Genuine Garrett clipped and lightened turbine wheel to reduce the backpressure,
– Genuine Garrett compressor housing,
– Genuine Garrett exhaust manifold,
– Genuine Garrett bearing housing,
– Genuine Honeywell electronic vacuum actuator,
– Dynamically Balanced.

What’s so special about this one?

1. Quick spool by applying lighter/enlarged 7+7 Billet Wheel.
2. Only oil cooling (there is not water cooling).
3. Efficient generation of Variable Nozzle Turbine.
4. 100% Plug&Play fitment.
5. Precise VNT adjustment.

The turbo is meant to work with ~260HP, boost 29PSI/2,1Bar. In order to reach that level of power, you need to adjust your exhaust and cooling systems as well. Professional ECU remapping is required!

The main advantages of Billet Compressor Wheels:

  • Billet Compressor wheels (or MFS Wheels Manufactured from Solid) are made from a solid piece of alloy (billet). A CNC miller performs the wheel from a CAD program.
  • Billet compressor wheels are far stronger than a cast wheel due to being machined from a solid piece of material. This extra strength allows the wheel blades and hub to be thinner, increasing blade area resulting in increased air flow from a wheel with matching overall dimensions.
  • As the Billet compressor wheel can have thinner blades and hub, this means that generally, the MFS compressor wheel will also be lighter than its cast counterpart.
  • The improvement will add greater air flow.
  • Faster boost response at lower engine speeds.
  • Increased efficiency at higher boost pressures.
