Remove The Variable. Makt It Reliable

HARRINGTON DIESEL 6.0L POWER STROKE T4 TURBO KIT.

Historically, the 6.0L Power Stroke has been one of the more problematic diesel power plants due to a few design issues, but with the right parts and consistent maintenance, it’s more than capable of doing the things most truck owners ask of their rigs. Injector failures, leaking head gaskets, broken EGR coolers—these are all common repair items on the 2003-2007 Ford diesel, but those are all things that can be improved thanks to the vast array of aftermarket options for the 6-liter.

Similarly, something that has affected just about every diesel (Power Stroke, Duramax, Cummins) since their introduction in the mid-2000s is the variable geometry turbocharger. While their super-cool technology and overall functionality works extremely well when new, as the mileage racks up it’s not uncommon to see soot buildup and normal parts wear affecting performance within a power band turbo.

The variable geometry turbo can be a great thing and perform well in a daily driver and towing application. By using adjustable vanes on the exhaust side of the turbocharger, the truck’s computer will open or close those vanes based on multiple variables like throttle percentage, boost, and engine rpm to change the overall ratio of the exhaust housing for quick low-end response and strong top end power. You get the best of both worlds by running a small, responsive turbo at light throttle and the airflow you need to make peak power at heavy throttle.
