S500

The BorgWarner S500 is the LARGEST frame size BorgWarner produces.  This turbo is for SERIOUS POWER!  This frame is offered in 2 different variations; SX and SX-E.  The SX uses a cast 8+8 compressor wheel and comes in both 88MM and 91MM.  The SX-E uses a billet 10 blade wheel and comes in both 88MM and 94MM.  The SX will have a wider power band, where the SX-E will shine more at higher RPM.  The drawback of the SX-E and that it will be more laggy then the SX at lower RPM.  Bother turbos use the same race style compressor housing and 110MM/99MM turbine wheel.
