We built the Silver 64 as a compromise between the Silver 62 and the Silver Bullet 66. The Silver 64 was designed to handle multiple fueling upgrades and is equipped with an extended tip 64mm compressor wheel. The Silver 64 comes with a polished compressor housing and 360 degree thrust bearing. The Silver 64 uses a 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. The Sliver 64 can support 400-700hp.
*03-07 "CRL" Large Flange model will work with 03-07 5.9L trucks and will retain cast elbow allowing use of factory downpipe.
*03-04 "CR" Turbo will require removal of cast elbow from back of turbo. This will require an HX40 downpipe and exhaust modifications for complete install.
*04.5-07 Models will require a wastegate fooler or performance module that has wastegate control capabilities.
