hey guys i gotta question does anyone know the size of the factory turbo on a 6.7 and would it be an upgrade from my hx35 my dad is thinking of upgrading his and i figured if it was an upgrade for me why not take the free turbo


thanks guys

 

They decent sized. I'm really not sure what it takes to get the Variable geometry turbine system to work on a different truck either.

That may be a tall order. Like stated above, they are a variable geometry turbo, as well as being electronically controlled and water-cooled.

 

That BOMB is pretty tough to build...

even though the compressor & turbine are very similiar to the HE351W we're so familiar with from the 5.9L CR, and the relatively large (~20cm) exhaust housing closes down to less than 10cm for good spool-up and lower high-RPM drive pressure - the VGT actuator would need a stand-alone computer with a driver circuit capable of controlling the 3-phase brushless DC motor.

The water cooling plumbing is easy enough to install.

I'd advise your Dad to use the existing turbo as the secondary in a twinset - that way he keeps all of it's electronic advantages (such as exhaust braking & WG control) while adding CFM capacity for plenty of extra fuel... besides, primary air is cheaper!
