64mm Stage One Turbo 03-07 5.9 Cummins


SKU: N/A Category:


The 3rd Gen Stealth 64 by Calibrated Power is an upgraded, drop-in, replacement turbo for 2004.5-2007, 5.9L Cummins.  It is designed to bolt in and requires nothing other than removing the factory turbo and dropping this one in its place.  The turbo features a custom profile, 64mm (actual measurement 63.5mm) billet wheel perfectly mapped to a modified compressor cover and 14% larger, 10-blade turbine inside the HE351’s 9cm housing.

The 3rd Gen Stealth 64 is one of the quickest spooling turbos we have tested for the 5.9L Cummins.  Even the most experienced enthusiast has a hard time telling the difference between a stock HE341/HE351 and a Stealth 64 during light throttle, daily driving.  This is directly tied to the tight exhaust housing and lightweight turbine wheel.  If you are going to daily drive your Cummins, consider a quick spool-up a “must-have”.
