1st/2nd gen 1991.5-2002 Cummins Turbo

These units are built to be 100% drop in’s, with no physical modifications required. All of these units are built with exclusive race covers by GT Performance Chargers. Spool time, in any size built will be similar to your OEM unit as these are still small frame turbochargers. The larger the size you go the less desirable it’ll be for towing, along with being less friendly for in town commuting. 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: 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

Additional information for picking the right size:

“The OEM compressor can be from a 50mm to a 60mm in the holset platform. We offer 4 compressor sizes.

60mm This is a great compressor for basic builds. This unit will far outflow any stock wheel as well as out spool it. This is paired with a 60mm turbine. Consider something like this for a work truck or something that will fall in the 400ish HP range. A 60mm turbine is the OEM size on most units, our turbines are higher flowing 10 blade versions. Expect stock spool with a notable power gain in the midrange due to the flow increase.

62mm We pair this with the 64mm turbine. This is a great combo for guys that still work their truck and have basic fueling mods that just need a little more oomph and cooling when on the throttle.

63mm This compressor is almost always paired with a 67mm turbine. This size is also our most common drop in compressor across the board. They are just a really nice blend of performance and drivability for the everyday truck. You can make some impressive power numbers with a turbo like this but still hook to the hay wagon and get on down the road. Something like this is happy in the 500hp range, but is capable of much more if pushed.

67mm This size is built only on request and only on the 67mm turbine. This turbo can have a shorter service life. You the driver are responsible for its health. it will surge more while shifting at lower boost. It will however make way more power than a little turbo should be able too. This turbo can make well over 700hp in a competition setting, yet have pretty good driving characteristics unloaded. You can still tow with this turbocharger.” - GT
