The Garrett® Gen II GTX3582R Evo X Turbo Upgrade which allows you to push your AWD, rally-bred monster up to an estimated 850 HP+. It features a specially designed twin-scroll turbine housing that bolts-on to the EVO X stock exhaust manifold; and stock exhaust down pipe, which enables worry free fitment of aftermarket exhaust systems. The turbine housing allows for the retention of the stock exhaust heat shield for better temperature control as well as a stealth look. The compressor housing includes a ported shroud 4-inch diameter inlet and 2 inch diameter outlet. The compressor housing REQUIRES (i) custom hose connection 4-inch intake pipe; and (ii) hose connection compressor outlet adapter. The Garrett® patented dual ball bearing center housing is standard on both turbocharger options for unmatched power handling and unbeatable response. The EVO X Turbo Upgrade is a powerful, yet highly streetable enhancement to an already potent car.
