The Garrett 739619-5004S PowerMax GTP38R Turbocharger is a must have for any 99.5-03 7.3L Powerstroke owner that wants to get more out of their truck. Built with the Garrett exclusive Ball Bearing Cartridge, the GTP38R provides unbeatable response, efficiency and durability especially at elevated boost levels. As a “drop-in” replacement, this turbocharger mounts to the factory pedestal and retains the use of OE intake and exhaust systems.

The GTP38R PowerMax features an 88mm compressor wheel that provides 35% more flow than the 80mm wheel found on your stock turbo. Also included is a ported shroud housing that improves compressor flow range and surge control. The included 1.00 A/R housing allows for free flowing exhaust with reduced back pressure and can even reduce exhaust gas temperatures up to 200 degrees.

While this turbocharger is suitable as a replacement for factory equipment, it is recommended that additional fueling upgrades such as aftermarket tuning or injectors are installed or already in use. Includes turbo, 4” inlet hose, band clamp, oil inlet o-ring, oil outlet o-ring, & installation instructions. Fits F-250/350 & Excursion.

  • “Drop-In” Replacement
  • Max Recommended Boost: 40 PSI
  • 88mm Comp. Wheel
  • 1.00 A/R Turbine Housing

Note from Garrett regarding shaft play:
When the Powermax turbo is new, or has not operated for a long period of time allowing most of the oil to drain out, the rotating assembly will move more in the radial direction because there is no oil in the center housing. This condition is normal. As long as the shaft wheel spins freely and the wheels don't contact their respective housings, the assembly will function properly.

After installing intake and exhaust I was getting turbo surge and waste gate chatter also would run at 1200 degrees on steep climbs, now all I hear is the sweet whine of new turbo and quite a bit more power...also seems to run quite a bit cooler...can't wait to load up the 5th wheel!
Well worth the money!

Instant 19 lbs of boost! Sound is awesome too! I took 1st place at the Jesup pull last year and with this addition all I can say is wow! XDP is awesome to talk to and have great prices! This turbo should have been installed at the factory!!!!

I added this Garrett turbo with a AFE filter and Trans Command. My truck was the slowest on every grade, but now it pulls great! I was skeptical, but on my first test run my truck was at 100MPH and still accelerating.
