After an insane amount of delays and issues these can finally begin shipping. Price target was overshot by 40 USD due to needing to outsource the lever arm in North America as well adding in inconel filler rod in each package.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. Show more
