VNT17 Turbocharger Upgrade (MK4 ALH) 

This is an ALH version of the European PD 150 turbo (GT1749VB) and includes the turbo gasket install kit. Long proven to be more reliable than the stock VNT-15 turbo, it can reliably produce >150 whp with the necessary supporting mods and tuning. Depending on the plumbing desired this turbo may need to be re-clocked. That procedure can be found HERE

Combine our Genuine Bosio nozzles, our Injector Calibration or Hot Swap program, chip tuning or Q Loader, and on a 5 speed transmission add the stronger South Bend clutch to create a great package. We even have a 150 HP Package that's a great combination.... or you can build the car in steps.

This turbo can ship with our exclusive, plug and play, billet aluminum, compressor outlet adapter; making this virtually a PnP upgrade for the ALH. We offer the adapter in three diameters; 1.25" (OD), 1.75" (OD) or 2" (OD). We normally ship the 1 1/4" adapter, since this is the correct size for the stock hose. If you have our Upgraded FMIC plumbing you will need to go with the 2" version, please indicate above. The new 1.75" adapter is for our upgraded SMIC plumbing kit and can be ordered above.

We Highly Recommend getting our Stainless Steel Oil Braided Supply Line as well. The stock ones are rigid and can break during removal or installation and the flexibility of the braided line makes for an easy installation.

This turbo is brand new from Garrett, not rebuilt and includes our extensive Turbo Installation Kit.  There is no core deposit.

A note to early ALH owners: This turbo requires the same support bracket and oil return line as the latest version of the VNT-15. If your car was produced before mid-2001, the turbo support bracket, oil return line, and oil return line block fitting will have to be replaced with the updated version of these parts. We do sell a retrofit kit that will help in this endeavor (can be ordered above). If your ALH was produced after mid-2001, this is a direct install.
