Kinugawa TD04HL Turbo Upgrade for Volvo 740 & 940 (B230FT / B230FK) — 270 to 370HP

The Kinugawa TD04HL is a direct-fit performance turbocharger upgrade for the Volvo 740 and 940 equipped with the B230FT or B230FK engine. It replaces the factory TD04H-13C-6cm unit with a larger TD04HL-16T, 19T, or 20T core in a 7cm conic turbine housing, delivering significantly more airflow and power potential without major fabrication.
