MuchBoost VNT17/20 Upgraded Turbocharger equipped with an Enlarged Billet Compressor Wheel. It is based on a genuine Garrett turbocharger, which means that the installation is P&P. The turbocharger is meant to work with 1.9/2.0TDI engines.

It fits the majority of transverse and longitudinal engines with the engine codes mentioned at the bottom of this page.

The turbo delivers up to 220-230HP which means it could be perfect for a faster daily driver, to gain some additional power.

Main Features

• The potential 220-230HP,
• Fast spool thanks to enlarged Billet/Cast Compressor Wheel,
• High air-fuel ratio including high peak torque achieved at low engine speeds.

Details on the construction of the turbo:

• Modified genuine GT20 compressor housing,
• Modified genuine GT17 turbine housing,
• Enlarged High Flow turbine wheel from ARL 150 PD turbocharger,
• Genuine bearing housing,
• Upgraded Journal bearing system that allows holding more boost,
• 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.

Mounting tips:

Steps to be performed during assembly:

• The Installation of Inlet&Outlet pipes (we recommend stainless steel).

Other significant modifications

In order to reach that level of power, you need to adjust your fuel, exhaust, and cooling systems as well.

Example project

Please take a look at one of our clients’ dyno graphs after installing the turbo. They did 218HP! Full setup:

Another great project with this turbo. Golf V managed to produce 204HP and 393Nm of torque. Dyno graph below.

The next project we would like to show you. This time, our client managed to produce 201HP and 405Nm with this turbo. The car was also equipped with:

• OEM Injectors with 50% Firad nozzles,
• TA Technix upgraded intercooler,
• 2,5″ Custom downpipe,
• Stock catback exhaust,
• Stock airbox

Please take a look at the dyno graph below:

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