Description

The Borg Warner S300SX3 (S366/73/.91) is a universal turbocharger engineered to address common weaknesses found in standard S300 turbos, offering higher-quality castings and upgraded bearing materials. This unit is built for high-performance applications and supports a broad horsepower range from 320 to 800 HP, with a maximum flow rate of 90 lb/min. Key features include a 66mm inducer compressor wheel with extended tip technology for improved efficiency and a 73mm exducer turbine wheel. The turbo utilizes twin hydrodynamic journal bearings for reliable operation and longevity. It also offers adjustable compressor and turbine housing orientation and compressor cover recirculation grooves. The turbine housing features a 0.91 A/R ratio, with other options like 0.88 and 1.00 also available. It is important to note that this is a universal turbocharger and is not vehicle-specific. Installation may require extensive modifications, fabrication, and the purchase of additional components.
