2003-2004 Cummins Phatshaft 64 Turbo (364240651A)

Fits

The original PhatShaft is the perfect turbo for quick spool and low-end performance. The Phat Shaft turbo also has the overall volume for overall torque for efficient full-throttle power. The PhatShaft can be purchased with a 12 or 14 turbine housing matched with a 65mm turbine. Industrial Injection suggests a 12 cm turbine housing if the engine is a 12 Valve and has moderate fueling upgrades such as 300hp injectors and a cam plate.  The benefit of the 14cm exhaust housing is lower Exhaust Gas Temperatures. The original PhatShaft is available in three different compressor sizes, 62mm, 64mm and 66mm. . The wastegate is set at 40psi to prevent head gasket failure on the PhatShaft 62 and 45psi on the PhatShaft 64 and 66.
