MuchBoost 1.7 CDTI A17D Upgraded Turbocharger with a Custom Billet Compressor Wheel and a Clipped Turbine Wheel. It is based on an original Garrett turbocharger, which means that the installation is 100%P&P. The turbocharger is meant to work with Opel Astra J, Meriva B, and Zafira B with the 1.7CDTI 100-125HP engines.

The turbo delivers up to 210% power (110 extra HP) over the factory specs. It is a great choice for someone looking for a bit extra HP from their daily driver. MuchBoost turbo allows you to get more from your engine and enjoy it even more than you’ve been so far.

We have developed 2 modification options that allow you to reach anywhere from 170HP to 210HP.

MuchBoost 1.7CDTI A17D 170

Upgraded turbocharger with an estimated potential of ~170HP at the crank. The list of modifications:

• Precisely machined seal plates and compressor housing,
• Genuine Garrett compressor housing,
• Genuine Garrett bearing housing,
• Genuine Garrett exhaust manifold,
• Upgraded journal bearing system that allows the turbo to hold more boost,
• Original actuator,
• More efficient and larger Billet Compressor,
  
• Clipped Turbine Wheel,
• Dynamically balanced,
• Perfectly calibrated VNT system + dynamically balanced. We use a modern VISCOM flow bench and Schenck balancing machines,
• The compressor and turbine wheels are balanced separately, and then the whole core is high-speed balanced using VSR balancing machines at speeds similar to the level seen in the vehicle.

MuchBoost 1.7CDTI A17D 210

Upgraded turbocharger with an estimated potential of ~210HP at the crank. Modifications compared to the 160 option are the same except:

• Bigger Compressor Wheel,
• Larger Turbine Wheel,
• Machined exhaust housing.

Other significant modifications

The turbo is meant to work with ~170-210HP In order to reach that level of power, you need to adjust your fuel, exhaust, and cooling systems as well.

A set of gaskets is included with every option you choose!
