G30-770 Ball Bearing KURO Turbocharger Kit for VW Golf MK7 / 7.5 & Audi A3 / S3 8V (EA888.3)
Unleash extreme airflow and reliable high-boost performance with the KURO G30-770 Ball Bearing Turbocharger by Arashi Dynamics — a stock-location IS38-upgrade turbo engineered for the MQB EA888.3 platform. Designed for MK7/MK7.5 GTI, Golf R, Audi A3/S3 8V, and similar MQB applications, this turbo delivers faster spool, stronger mid-range punch, and significantly higher flow capacity than the factory IS20/IS38 units.
Built with a brand-new ceramic ball-bearing CHRA balanced by Turbo Technics VSR machinery, the G30-770 provides smooth operation, high temperature stability, and increased power potential. With a billet point-mill compressor wheel, high-flow turbine, and SCH22 turbine housing, this turbo is built to support serious performance builds while maintaining bolt-on OEM-style fitment.
