BorgWarner S400SX 71mm Turbo

This is an affordable option for a turbo to compete in the SFWD class.  The 71mm S400SX3 is borgwarner's answer to offering exceptionally high value and ultra high performance turbos for the drag race community. Using a 7-blade Extended Tip compressor wheel w/ 71.08mm inducer and 100.2mm exducer, this turbocharger is often called "S372" because it is ideal for drag racing classes with a 72mm inducer limit, it works equally well for low boost large displacement V8 engines as it does high-RPM small displacemnt 4cyl 750-1050+ whp applications. The S400SX turbos share identical fitment as GT42R (5" inlet compressor hsg inlet and 4" vband turbine outlet) and is ideal for applications looking for T6 levels of power but with T4 spool and fitment. Available with a 1.10 A/R turbine housing OR upgradeable to a 1.25 A/R for extremely high boost operations and if extra exhaust flow is required. Full-Race strongly recommends using an upgraded transmission! Journal Bearing and Oil Cooled only
