Precision-engineered bolt-on turbocharger upgrade for Toyota 3S-GTE powered Celica GT4 (ST185, ST205) and MR2 Turbo (SW20) platforms. Features a Garrett 60-1 style cast 7+7 compressor wheel (60/76mm) for proven high-flow performance, direct replacement for CT20B and CT26 twin-scroll turbos, and complete generation-specific installation hardware for Gen 2 and Gen 3 engine variants.

Engine Code: Toyota 3S-GTE / 3SGTE (all generations compatible with CT20B or CT26 twin-scroll turbo)
Fitment Note: Custom housing bolts to stock manifold and downpipe — compatible with aftermarket downpipes and intercoolers designed for CT2x turbos (CT26/CT20B/CT21/CT27).

CT20B 7-bolt to CT26 6-bolt turbine housing outlet swap: cut or omit the extra stud for compatibility.

⚠ Important: Does NOT fit Generation 4 (ST215) or Generation 5 (ST246) — these use an exhaust housing cast into the cylinder manifold, incompatible with this turbo's separate turbine housing design.
