Introducing a fully-rebuildable drop-in performance turbocharger for 1999.5-2003 Ford 7.3L trucks

Assembled with a custom Wicked Wheel® 2 performance billet compressor wheel and a Turbo-Master™ mechanical wastegate controller, this is an upgraded, brand-new turbocharger to replace the GTP38 used on stock 1999.5-2003 Ford 7.3Ls.  

The center section is a journal bearing support with a 360° thrust washer capable of handling higher boost levels. This turbocharger is fully rebuildable.

feature exclusive to all DieselSite turbochargers: a fully CNC-machined wastegate. ALL OEM cast or stamped-style wastegates leak - even when fully closed. In our testing we found that even at very low drive pressures of 5-10 psi the wastegates leaked off valuable pressure. Our machined wastegate holds 100% of drive pressure when closed.

Features include:

  • 1.0 A/R turbine housing
  • 360° thrust washer
  • Turbo-Master mechanical wastegate controller
  • Larger high-performance Wicked Wheel® 2 compressor wheel (66mm inducer/94mm exducer)
  • Drop-in replacement - all o-rings needed for installation are included
  • Full 1-year Warranty!

Benefits include:

•    Reduced EGT’s
•    More Horsepower
•    Increased performance
•    Faster spooling and throttle response
•    Fully adjustable drive pressure relief system
•    Superior surge control & air flow over stock and modified turbochargers

Benefits of journal bearings are longer life and more durable and less susceptible to debris from oil.

For those that live at high elevations or for whatever reasons feel they need to - YES, YOUR STOCK .84 AR EXHAUST HOUSING WILL FIT AND WORK WELL. There is a downside to expect of slightly higher exhaust temps, but spool is better at high elevations.
