Backplate Adapter Ring for T04E FRAME Compressor Housing, for GT/GTX Turbos
T04E Frame Compressor Housing Backplate adapter ring.
Goes between the CHRA and the Compressor Housing
Standard on the GT30 Series Turbos but also can be a "compact" option on other larger turbo models such as GT/GTX35 or can also be used when a GT28 series turbo is running a larger than stock compressor housing. Please always match the compressor housing "frame size" to the appropriate back plate adapter ring.
