    Is it possible to modify the Holset Center section to utilize ball bearings? I Have an he351cw on my 4g63 and if it could spool faster it would rule. How much would the 67 mm turbine and housing lower spooling rpms on a 4g63?

      The larger turbine and housing help gain spool because of the 76 mm inducer of the turbine vs the 65 mm inducer of turbine.

    So I have the wicked wheel 2. And as you stated I never did do the exhaust turbine and housing … wondering if I just but this kit and throw on the wicked wheel 2 and it’ll all go back together on my 06 5.9 6 speed manual with the he 351. Also wondering if it will sound similar to the holset cheetah. That’s one of my main goals. I love that sound. It just my daily driver. Occasionally pull about 10,000 3x a year or less

    Should I use my stock compressor wheel for this set up or should I use the wicked wheel 2 that I have? 2006 5.9

    I put the wicked wheel 2 on my stock turbo and spores better but it seems to run hotter I don’t like that

      If you upgrade the turbine wheel then you will see a reduction in EGTs, usually 400 degrees less than stock with this turbine upgrade.
