VNT-17/22 upgrade turbo (MK4 BEW)

Not Available
Pricing: $1,369.00



The 17/22turbos has proven quite popular, because it has all the goodness of the fast-spooling factory turbos with a compressor supporting higher airflow, with few tradeoffs for street use. Plus, it will generally bolt right up to a stock ALH or BEW engine in place of the original vnt15 or kp-39, with minimal adaptation on the compressor inlet and outlet. The stock Mark IV TDI exhausts bolt right in place for easy installation, and all of our upgraded exhaust products like our 3 inch turbo back system integrate seamlessly.

The 17/22 hybrid adds a larger 52mm compressor wheel and housing to the venerable VNT17 (1749VB) hot side. The compressor supports higher flow rates at high RPM compared with the original turbo and vnt-17, which allows somewhat extended high-rpm performance. Also, since the compressor maps max efficiency, island is positioned right where a 1.9 liter TDI experiences typical highway cruising conditions, andless exhaust pressure is needed to power this turbo at highway speeds. This leads to improved highway fuel economy in many cases.

The BEW version has the smart actuator that includes an electrical connection for a position sensor. The BEW engine was found in 2004-2006 Golf TDI, 2004-2006 New Beetle TDI, and the 2004 thru 2005 Jetta TDI with PD injection

Although they are satisfactory in an otherwise stock car with no other performance modifications, these turbos will perform best if your TDI has upgraded injectors and ECU tuning from KERMA. We can also adjust the ecu to allow using the ALH version in a BEW without the check engine light thats usually triggered by the missing G500 actuator position sensor if needed. An upgraded exhaust helps the turbine spool faster, and freeing up the intake tract with our OMI intake pipe and an AFE intake system makes things a lot easier for the compressor, especially at lower engine speeds and higher boost (higher pressure ratios.) Besides that, an upgraded intake and exhaust really sound cool!

One of the best combinations weve tested includes this turbo, a Colt Cam (Stage 2 BEW cam),the 3-inch turbo-back exhaust, and an OMI intake. This really hits the hardware sweet spot, with the cam and exhaust helping the low-end response of the bigger turbo while reducing the compressor noise at higher boost levels. While these turbos also work well in cars that are otherwise completely stock, the airflow add-ons really compliment the larger compressor!

As with the 1749VB, a 3-bar map sensor will enable full use of the turbos available range with the proper ecu tuning, for long service life.

On an otherwise stock car; fitment requires either stretching the compressor outlet hose over the compressor outlet, or replacing the compressor outlet hose with the equivalent BEW (PD100) compressor outlet hose and trimming it to fit. On the turbo inlet side, a BEW turbo inlet pipe boot is necessary to connect the turbo inlet pipe to the turbo inlet or our OMI for the BEW makes for a seamless fit.

This turbo is composed entirely of new Garrett components, and is assembled by a leading Garrett Distributor
