We have already had the IS38 turbo upgrade CHRA with a larger billet compressor wheel to bring more boost. Recently, we cut an IS38 turbo bearing housing into sections to upgrade to ball bearing turbo 06K145722H 06K145722A for Golf R and Audi S3.
Since the OE IS38 turbo is journal bearing type, to convert it to ball bearing type, we need to design the central housing to fit our ceramic ball bearing system. Then a mold of the new designed bearing housing will be open for casting.
