Product Description

The Stage 3 billet upgrade combines our 65 mm high capacity compressor wheel with the 56 mm high flow turbine and hybrid ball bearing internals in a standard package.  The resulting power on 2.5 liter applications is 350-370+ WHP with a very wide on boost power band from 3,000 to over 6,500 RPM, high boost (22 psi +) capacity and the response of a much smaller turbo.

  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.  
Our Stage 3 billet wheel upgrade service includes our 7/7 ultra high blade 65 mm compressor wheel with ETT along with new oil lines and gaskets and water pipes to the package. To optimize performance with the billet wheel Full porting and polishing is an additional cost option.

The standard 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.

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

How the service works:

Thatís the easy part, just buy the service from our store, fill out the DOWNLOADABLE ORDER FORM and ship us the turbo. We disassemble, clean and prep the housings and reassemble the turbo with our unique hybrid ball bearing and billet compressor wheel CHRA.

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 or upgrades 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.
