IS38 ball bearing turbo with electronic actuator upgraded from journal bearing to ceramic ball bearing. The ceramic ball bearings are from Germany. This ball bearing IS38 turbo version is with larger exducer billet compressor wheel than stock IS38 06K145722H turbo.
To develop ball bearing IS38, we designed the ball bearing bearing housing and opened a new mold for it. Unlike GT ball bearing turbo chra, the external design of this ball bearing IS38 chra is same as OEM, so there is no need to use any oil restrictor.
