CT26 60-1 Turbo Upgrade for Toyota 3S-GTE Engines
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.
Vehicle Compatibility
Toyota Celica GT4:
- 1989.9 – 1993.10 Celica ST185 (3S-GTE)
- 1991.10 – 1992.4 Celica ST185RC (3S-GTE)
- 1994.2 – 1999.8 Celica ST205 (3S-GTE)
Toyota MR2 Turbo (SW20):
- 1989.12 – 1993.11 SW20 Series 1 & 2
- 1993.12 – 1999.8 SW20 Series 3
- 1990–1993 MR2 Turbo (North America 1991–1995)
- 1993+ MR2 Turbo (Japan)
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).
⚠ 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.
