You can purchase GTP38 turbochargers online for your 1998 through 2003 Ford 7.3L Power Stroke diesel here at USDieselParts. We carry quality factory replacement remanufactured GTP38 Garrett turbos for your Ford Powerstroke, as well as aftermarket high performance replacement GTP38 turbos from BD Power, Garrett, Industrial Injection and ATS Diesel Performance. An aftermarket high performance Ford Powerstroke GTP38 turbo is a great match if you plan to install a set of high performance injectors or an aftermarket high pressure oil pump such as the Adrenaline HPOP. A performance turbo will deliver more boost, get better throttle response, lower your EGT's and increase fuel economy. For those on a budget, we also carry high performance turbine housing upgrades for your stock GTP38 turbocharger to help decrease turbo lag and compressor wheel upgrades that increase airflow. If your turbo pedestal is leaking oil, then we also have new Garrett replacement turbo pedestals for sale. If you have any questions about upgrading your Powerstroke turbocharger, then please give us a call at (800) 823-4444.
