Limited quantity of unsold complete kits ready for immediate shipping.

Welding Note:  It is highly recommended to have this done by a specialty welding shop that understands they are working with a more exotic material.

Note: The bushing can be used in the oem/china RS4 turbine housings as is or with moderate grinding of a the lip.  The bushing will not fit in a china (or likely oem as well) RS6 turbine housing without boring out the turbine housing.  We have omitted using the bushing in both setups with no issues on the stainless version.
