Product Description

The Stage 2 billet compressor wheel upgrade is the perfect setup for Time Attack Street Class which allows for a maximum inducer diameter of 50 mm.  The 49.6 mm inducer 64 trim  The 7/7 blade configuration compressor wheel gets in just under the limit and pumps out  more than 44 lb/min of boosted air at full chat.  With the stock turbine housing going to the 56 mm turbine is a killer 340+WHP setup with quick response and high boost threshold.


Our Stage 2 hybrid ball bearing and billet wheel upgrade service includes our 7/7 blade configuration 62 mm compressor wheel with ETT along with new oil lines and gaskets and water pipes to the package.

  1. Hybrid Ball Bearing Upgrade


    Just introduced for RHF55 turbos, the Six Star Speed Hybrid Ball/Journal Bearing Upgrade.  This system replaces the compressor side journal bearing with a super precision angular contact ceramic hybrid ball bearing.  The same bearing used in our XR turbos.  The single angular contact bearing also takes up thrust in one direction so the OEM thrust bearing is retained as well as the turbine side journal bearing.  The result is the virtual elimination of radial shaft movement, increased response and dramatically increased durability.  The long wearing hybrid ceramic ball bearing requires almost no lubrication thus reducing critical oil requirements for the turbo.  Axial shaft play is also reduced extending the life of turbine seals.  
Now available: 56 mm turbine wheels. The 56 mm turbine wheel increases exhaust flow capacity with a negligible decrease in response. Mid range and top end power increase suitable for 2.2 liter motors and larger.  The 56 mm turbine upgrade adds 2 weeks lead time.

This exclusive products features and service are only available at Six Star Speed.

  2. 1
    Purchase the service with your desired options. You can add options such as PnP, actuator upgrades, and coaitngs  to your order and purchase in advance.  
    • Advance purchase reserves your position in the work queue and saves time as we have to confirm requested work and option pricing before work begins.  
    • Make sure to fill out the service form regardless if you pre-order or ship/drop the turbo with us. 
    • If purchasing the turbo outright select the appropriate turbocharger type and applicable core charge.  Outright purchase may add 1-2 weeks to build time depending on availability

  3. 2
    Package your turbo securely. If you are shipping a turbo to us please package it such to avoid damage.  Wastegate actuators are the most vulnerable to damage and are a component of the turbo that will be re-used if in operable condition.  Make sure you have enough cushioning material to guard against the conditions of normal handling.

  4. 3
              Make sure to include the service form or a copy of your purchase receipt. Including the documentation saves time and allows us to get started right away.  We get a lot of turbos in each day.  Turbos received without service requests will unfortunately go to the back of the daily work queue.  Confirming the service request with without the docmentation may add 1-3 working days to the turn around time.  The service form is located here SERVICE FORM DOWNLOAD

  7. 6
    Completion and return shipping. When your turbo order is complete the system will be updated with tracking details and a message sent to you.  Tracking numbers are usually live by 8 pm on the shipping day.  For turbos without a pre-order invoices and payment will be processed before the turbo ships and tracking numbers sent by email.
