For those seeking up to 750 RWHP, the S475/Stock IHI Turbo combination is recommended, providing optimal spool characteristics with a stock fuel setup. For over 800 RWHP, the S480/Stock IHI Turbo is a better choice, offering enhanced top-end performance. For over 900 RWHP, the S480/64mm Drop-In Turbo setup is ideal, with improved top-end power and moderate spool attributes.
