New open box turbo compressor and turbine upgrade for Garrett/Honeywell MGT-1446 turbos found on the VR30DETT in the 2016+ INFINITI Q50/Q60 and 2023+ Nissan Z. Similar to the PURE Stage 2 upgrade, these require the stock compressor and turbine housings to be ported and opened up a few millimeters to ensure fitment. Professional machining and VSR balancing is highly recommended, otherwise catastrophic turbo failure will occur. CNC drawings for compressor and turbine housing machining can be found in the last few pictures. Please ensure you have adequate fueling and tuning required for upgraded turbos for these to work properly. For some reason these were delisted from MAMBATEK’s US website, but more information can be found on their Japanese website here: https://www.mambatek.jp/ja/products/日産-vr30-z-q60-mgt14p-4256-580hp-アップグレード-ターボコンプレッサータービンホイール
