Stage 2 Turbo Upgrade – S63TU M5 M6 M8 X5M X6M


Available on backorder


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 4-axis CNC mill, right in our shop.  This retains the bolt on application for easy installation.

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