Toyota CT26 Turbo for 3S-GTE Celica ST185 | OEM 17201-74030

Searching for a Celica GT-Four turbo replacement that restores the legendary WRC homologation performance? The Toyota CT26 turbocharger (OEM 17201-74030) is the definitive induction component for the Gen 2 3S-GTE turbocharger platform. Unlike diesel CT26 variants used in heavy machinery, this 2.0L petrol turbocharger features a specific compressor map optimized for high-RPM gasoline combustion. It is a mandatory requirement for maintaining the mechanical integrity of the Celica ST185 and SW20 MR2, ensuring the twin-entry pulses deliver the instantaneous torque response that defined the 1990s JDM era.

Technical failure in aging 3S-GTE Gen 2 turbo units often manifests as significant shaft play, leading to catastrophic turbine-to-housing contact. Our CT26 units are manufactured with a turbine wheel cast from Inconel 713C alloy, providing superior resistance to thermal deformation compared to standard aftermarket iron. The twin scroll CT26 turbo housing is precision-machined to prevent internal bypass divider cracking, a common issue in high-mileage ST185 setups. Every rotating assembly undergoes VSR balancing at speeds exceeding 150,000 RPM, eliminating harmonic vibrations that cause premature oil seal failure.
