Fitment Notes: Industrial Injection 2003-2004 5.9L 3rd Gen. – PhatShaft 64 Turbo. – 350-600 HP – Note: **The 4″ HX40 style downpipe and clamp are required for installation on all 2003 and early 2004 3rd gen trucks.
HPX40 Downpipe is required for installation on 1994-2004 Cummins truck, 2005-2008 AUTOMATIC trucks will also require the HPX40 downpipe. PhatShaft (65mm T-wheel) For mild fuel upgrade – The PhatShaft 64 is mid range replacement turbo for towing. The PhatShaft can be purchased with a 12 or 14 turbine housing matched with a 65mm turbine however we suggest sticking with the 14cm exhaust housing. The benefit of the 14cm exhaust housing is lower Exhaust Gas Temperatures but it will be slower to spool in daily driving situations. The original PhatShaft 64 features 64 mm compressor with extended tip technology. The wategate is set at 45psi. All PhatShaft turbochargers are equipped with dual grooved bearings and an adjustable boost elbow. The original PhatShaft compliments moderate fueling upgrades and can support 300 – 550hp.
