A True Stage 1 turbo for the 6.0 Powerstroke guys.  We have been in the business a long time and have sold so many turbos.  After a lot of feedback from customers we came up with this design.  Something larger than stock, but "ACTUALLY" smaller than the stage 1.5 pmax/stage 2 turbos on the market.  This turbo shares technology with the new 2015 turbo design. 

This turbo is meant for the guys who tow heavy, want quick spool, more power, but don't want the extra lag associated with other larger stage 1.5/pmax/S2 turbos.  The only downside is that it is only meant for moderate injectors (stock and 155cc injectors).  It will still run great on 175 but you won't be able to clean up the top end on a heavy race tune. 


  • 61x88mm single plane billet wheel with extended tips to 93mm

NOTE:  These turbos are based off of the 2004-2007 turbo mounting style, to run this on a 2003 pedestal we will have to cut off the 3rd mounting bracket on the back of the turbo.
