Gt Performance Drop In Style turbo Charger For 5.9L Cummins 2003-2007

These are 100% drop in turbochargers. There are no physical modifications required for installation. Spool time will be similar to your OEM unit. The larger your turbocharger gets the worse you can expect it to tow as well as the less friendly it will become in a daily driver situation. In most all cases this style of turbocharger allows your truck to still be a truck and not just a toy. Turbos like this can be used in stock to wild applications. It is however very important to understand that the more extreme you get with a turbocharger, the shorter its service life can be. Bigger does not always mean better. Our large drop in's can play well over 800hp.

the 12 CM housing is excellent for 3rd gen swaps on mild 6.7's as well as higher RPM 5.9's that are trying to extract all the power they can.
