    reason I'm asking is i was suppose to have bought a k04 F23l with the following specs
    Inconel 713C alloy steel "Full Back" Turbine rotor
    Anti-Surge 7075-series aluminum Billet compressor wheel
    42CrMo High-strength rotor shaft
    Up-rated K16-series 360 Thrust Bearing and Ring
    26mm wastegate chamber with oversized 34mm cover
    K04-specification High Si-Mo (Silicon Molybdenum) cast iron turbine housing/manifold (1000 c)
    All parts and Product assembly Performed To OEM specs by OEM suppliers

    More horsepower !! Bolt on design !! Billet compressor wheel !!
    Bigger billet wheel than K04 53049880064 !

    However its stamped JH5 IT https://www.ebay.com/itm/176919600951
    I pulled the CHRA to check
    and have a Cast compressor side measuring 52.4mm/40mm 6+6 blade
    and a turbine side of 50mm/44mm 7 blade

    the turbine side looks right from my research but the compressor side looks small for what it should be

    What do you think???
