Kinugawa TD04HL Turbo Upgrade — 6cm Straight Flange — Volvo 740 & 940 B230FT / B230FK

Choosing the right turbo for your Volvo 740 or 940 means balancing spool response, power ceiling, and fitment. The Kinugawa TD04HL 6cm Straight Flange gives you five compressor wheel options in a single direct-fit package — from a crisp 230HP street setup all the way to a 370HP track-ready build — without cutting or fabricating your exhaust outlet. The straight flange housing bolts straight to standard Volvo downpipe configurations, making this the most versatile TD04HL option in the lineup.
