Audi A5 2.0TDI Turbo Upgrade CGLC Audi A4, A6 GTC1549VZ


Categories: , , , Tag:


GotTuned`s Hybrid Turbocharger built using custom CNC compressor wheel + clipped&lightened Turbine Wheel. This based on genuine stock GTC1549VZ turbocharger is the ultimate Plug&Play solution for Audi A4 B8, Audi A5, Audi A6 C7 working with CGLC with stock power 177HP.

The full list of changes applied is as follows:

– Journal bearings – so-called ‘360’,
– Modification of the compressor housing,
– Modification of the seal plate,
– Enlarged compressor Billet Wheel 6+6 GEN I,
– Custom turbine wheel clipped and lightened to help reduce backpressure,
– Genuine Garrett compressor housing,
– Genuine Garrett exhaust manifold,
– Genuine Garrett bearing housing,
– Genuine Hella electronic actuator,
– Dynamically Balanced.

What’s so special about this one?

1. Quick spool by applying lighter/enlarged 6+6 Billet Wheel GEN I.
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 ~230HP, boost 28PSI/1,95Bar. 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.
