Product Description

  1. Six Star Speed introduces staged rebuilding and upgrades for RHF55 frame Subaru turbochargers. We have four compressor wheel configurations each with their own performance benefits. The Stage Zero includes our high performance rebuild with OEM cast wheel which restores and extends the performance of the stock turbo.  All upgrades from the Stage 1.5 require compressor housing machine work to fit the larger wheels.  The large capacity 56 mm turbine is optional for Stage 1 and 2 builds, standard on Stage 3.

    • The Stage Zero  build is our standard repair service which includes repairing your turbo with our high performance RHF55 hybrid ball bearing/journal bearing CHRA.  The service includes rust coating of the turbine housing and install kit which includes a teflon braided oil line with application specific fittings and GrimmSpeed 7-layer uppipe and downpipe gaskets. 
    • The Stage One  billet wheel upgraded adds a 7/7 blade configuration tall blade billet compressor wheel in place of the stock cast unit, smaller hub and 65 mm extended tips for an over 12% flow increase over stock.  No modifications to the compressor housing are necessary.
    • The Stage 1.5  billet wheel upgraded features a 7/7 blade configuration with a larger trim tall blades, smaller hub and 65 mm extended tips for an over 15% flow increase.
    • The Stage 2 upgrade features a larger 62 mm exducer with 67 mm extended tips, a large 49.6 mm inducer (64 trim) smaller hub and a 7/7 high blade configuration with a capacity of over 44 lb/min.  We call this our "Time Attack" Compressor wheel and is the largest legal inducer for time attack street class.
    • The Stage 3 upgrade features our big volume 65 mm exducer billet compressor wheel with 70 mm extended tips, a large 65 trim innducer and a capacity of over 50 lb/min.  This compressor wheel has a very wide map and combined with the starndard 56 mm turbine offers a 350-370+ WHP capacity with amazing low end response on 2.5 liter motors.

  4. 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. 
  6. 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

  7. 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.

  8. 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

    Ship your turbo to us or drop off if you are local When shipping your turbo you may use the courier of your choice.  UPS or FedEx are the most reliable and USPS has the advantage of delivering on Saturdays.  If you are local to Northern VA you can drop off your turbo at  Fairfax Auto Parts Machine Shop 8701 Lee Highway Fairfax VA 22031 7:30 am - 5:00 pm
  10. 5
    Confirmation of receipt and estimated completion time. When we receive your turbo we will confirm arrival and update the system to show the estimated completion time.  If you dropped or shipped the turbo to us without a pre-order we will contact you by phone or email to confirm details, service request, pricing and lead time.
  11. 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.
  12. 7
    Receipt and installation.  Your turbo will ship to you complete and ready to install with documentation of guidelines and instructions.  Please follow them to the letter.  We always recommend professional installation of turbochargers.
  13. Basic service charge applies to a turbocharger in serviceable condition. Serviceable condition requires that the unit does not have a broken turbine shaft or turbine housing damaged by foreign object debris such as melted aluminum and free from damage to the compressor housing  abradable ring.  Turbochargers received with unserviceable damage will be given the option to purchase the service parts at the listed prices or have the unit returned. Refunds will be issued for returned unserviceable turbochargers minus a $90.00 inspection and shipping fee.
  14. Compressor Housing Damage - If your compressor housing is damaged and not able to be used or cut to a larger size then replacement charges will applied as follows:  VF37, VF39, VF43, VF48, and VF52 $80.  VF34 and VF30 $160
  15. Turbine Housing Damage - If your turbine housing is able to be used (this is likely to be the case in a broken shaft failure)  then replacement charges will applied as follows:  Single Scroll $60.  Twin Scroll $200
