The VIPER PhatShaft 63 was designed to handle mild to aggressive fueling upgrades to increase overall performance. The Viper comes equipped with an extended tip 63mm forged milled compressor wheel and 360 degree thrust bearing. The Viper utilizes the 68mm turbine wheel and is available in a 12cm or 14 cm exhaust housing in which we modify the angle of the exhaust nozzle, maximize the wastegate ports, and enlarge the wastegate chamber for full wastegate travel. Like all PhatShaft turbochargers it is equipped with dual grooved high performance bearings and an adjustable boost elbow.
NOTE: Requires HX40 Downpipe
