A 6.7 cummins comes factory with a restrictive 12 blade 60mm turbine. Which can easily become a restriction when you start chasing power. All of these units come with 10 blade high flow turbines regardless of the size.

These units are 100% drop in ready to rock and roll, no physical modifications required.

The Hybrid units allow GT to install your choice of larger turbines such as the 72/64, 76/67 and a 76/71

The 60/60 and 63/67 are unchanged from previous models, with 70/60 and 67/70mm turbine wheels.

60/60 is an excellent choice for stock or simple tuned trucks. These are excellent for towing. Stock spool with a little bit more CFM and a better flowing exhaust resulting in lower drive pressures. This turbo should be ran on stock engines up to around the 450HP range.

63/67 is a great choice for daily driven trucks with mild supporting mods that tow occasionally (not daily). This turbo is capable of around the 650HP range.

Hybrid HE300/400VG

63/64 is a great option for mild builds that tow heavy and often where daily driving is the focus. This turbo is a bridge charger for guys that want a little more than the 60mm but don’t want to lose towing capabilities. This charger should be ran on trucks from stock to around the 550HP range.

65/67 is a great option for guys that want to retain their Exhaust brake, mild towing with more focus on performance than working their trucks. This turbo will still be able to tow lightly. With HP potential of around 700.

65/71 will push the usable power a little farther out in the rpms.  This turbine is aggressive! This WILL be laggier than the smaller units. When you let them flow you gotta deal with a little lag to make that power. This combo should be used primarily for street and smiles per miles. Towing is not recommended but possible with a responsible driver and the proper supporting mods. HP potential over 700.

67/71 is the beast! This is for guys chasing numbers on their VGT equipped trucks, towing is not recommended, good tuning as well as the fuel to support this turbo will be crucial! HP potential over 700.

With the addition of these new options GT is now able to tailor in builds more precisely for each and every one of your builds.

Turbos like these can be used for stock to extreme applications such as throwing some more horses on the daily or giving the sled truck some more juice! Understand though that the bigger you go, the shorter it’s service life may be.

NOTE: Pricing includes billet actuator, no relearn process is required. Drop in and go! Also, these turbos are not on hand at our shop and are custom ordered from our supplier. There is an option for powder coat, please contact us for more info if you’d like to do so! 814-421-3395 or cody@tcdiesel.net
