The S257SX‑E Supercore (also known as S200SX‑E 57/61) 12769095003 is a high‑performance turbocharger super‑core assembly built for street, drag and track racing applications for both gasoline and diesel engines
This unit comes as supercore only: including bearing cartridge, compressor cover, compressor wheel, turbine wheel and mounting hardware. Turbine housing, speed sensor, V‑band fitting and oil drain accessories are not supplied. You can match your preferred T3 / T4 turbine housing with different A/R ratios to achieve your target spool and horsepower output.
Equipped with forged‑milled (billet) compressor wheel with extended‑tip technology, optimized aerodynamics greatly improve airflow efficiency and boost response. Pre‑machined boost port and integrated speed‑sensor port support professional ECU tuning and turbo shaft‑speed data logging, ideal for serious performance engine builds.
Oil‑cooled journal bearing design ensures stable long‑term operation under high boost conditions, supporting max airflow up to 65 lbs/min, power range from 300HP up to 650HP. Perfect for single‑turbo conversion projects or twin‑turbo setups on modified performance vehicles.
