The Industrial Injection Original PhatShaft Series Turbos were designed to handle mild fueling upgrades to help increase overall performance and be perfect for towing and daily driving. The PhatShaft comes equipped with an extended tip 62mm, or 64mm forged milled compressor wheel and 360 degree thrust bearing. The PhatShaft utilizes the 65mm 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. We recommend the 12cm Housing for 12 valve and 24 valve trucks for faster spool up.
