Constructed of billet aluminum, our larger impeller wheel is 5-axis CNC machined and flows signifigantly more air.  The light weight impeller design and latest machining technology results in very short spool up times and great overall power.  Tailored for use exclusively with the factory M157 Garrett gt22 frame makes this a 100% bolt-on installation.  No custom oil and water lines to leak, no headaches.  Every factory line connects right to the new turbo, using factory gaskets.  Replacing the oil feed lines with new OEM Oil Feed Lines is recommended, especially on higher mileage vehicles. 
For maximum results, the combination of our Weistec Downpipes, and Weistec High Flow Air Filters is recommended.  An M157 ECU Upgrade is required.
