The RK Autowerks Stage 2 Turbo Upgrade is the perfect solution for those looking for more power while retaining stock drivability and turbo spool.  You are still able to use launch control with this setup.

To fit the larger turbos, we mill out the stock housings on our 5-axis CNC mill, right in our shop.  This retains the bolt on application for easy installation.


Turbo Cores:

Currently, you must send your turbos in to be upgraded.  Turnaround time is usually between 1-3 days, depending on workload.  We do our best to get them back to you as fast as possible to minimize downtime.
