1.00 A/R turbine housing for free flowing exhaust with reduced back pressure and 
up to 200° F reduction in exhaust gas temperature 
Maximum recommended boost level is 40psi

The PowerMax Ford Powerstroke Turbo Kit includes: 

• 4-inch inlet hose 
• Band clamp 
• Oil seal rings 
• GTP38R Turbocharger 
• Installation instructions

*Ceramic Coating Details -

The Turbo Black ceramic was formulated for exhaust temps up to 2000*F and will hold in at least 60% of the heat from radiating out under your hood. Not all black coatings will achieve that function. These coatings have been specifically formulated for use on military aircraft.

By retaining the heat energy your turbo will spool up faster and more efficiently. We double coat the outside of the housing to protect it from rusting and it results in a much longer attractive finish while retaining heat. The two main functions of the coating is appearance and function longevity of your engine parts and gaining a more efficient running engine.

Please Note: We have head rumors of "knock-off" Garrett turbos being sold at very low prices.  We may be more than other companies but you can rest assured we get them directly from Garrett unlike many other resellers.

  1. Best mod yet 5 Star Review

    Posted by on Nov 1st 2016

    This is the best mod i have done to my truck yet. The sound is awesome an the pulling power is great for a mild build. Would definitely recommend to anyone with a 7.3!


  2. Not happy with the GTP38R! 3 Star Review

    Posted by on Oct 20th 2016

    02' F-350 ZF-6
    All these 5 stars and great reviews convinced me to purchase the 38r, but I gotta say I'm not happy.
    My truck lost it's low-end kick, that used to pull you back in the seat! I was running the stock turbo with the ATS compressor housing. Stock turbo was running 3-5 psi boost @ 50 mph with the cruise on flat ground. Now it's not even boosting @ 65 going up an overpass...falling flat on it's face! Was hitting 30-35 psi max with wide-open-throttle too, but now not even half that. Top end speed is a lot higher, but top-end doesn't kick a Camaro's azz at a traffic light, or pull a dump-trailer full of stone! I gave it 3 stars cause the reliability of the ball-bearings.


  3. I don't know why Ford didn't run these turbos in first place 5 Star Review

  4. GTP38R 5 Star Review

    Posted by on Sep 23rd 2016

    I received the turbo and did the install. I did a lot of research in a turbo replacement for my stock F550 flatbed wrecker and needed a reliable update with better performance. The GTP38R I feel fit the needs and are pleased with the performance of my truck. The product was a direct replacement and had all of what I needed to complete the job and a nice addition to my truck...


  5. Nice addition 5 Star Review

    Posted by on Sep 17th 2016

    Turbo was well packaged, shipping is very fast(i live in the middle of nowhere Wyo), very pleased so far. Going to install this weekend


  6. Ecellent Service 5 Star Review

    Posted by on Aug 2nd 2016

    Shipping was fast. Product arrived quickly. Installation instructions were the best I have ever seen. The turbo also works GREAT!


  7. Great turbo 4 Star Review

    Posted by on Jul 30th 2016

    I am very pleased with this new turbo I have stock injectors and it still works great quick spool up fits well only issues I had

    1 adjust the waste gate BEFORE installing turbo you will thank yourself...

    2 silicone boot was to long didn't fit the greatest but it does seal up well

    3 the kit should come with a extra 4 inch clamp for the silicone boot I didn't feel stock hose clamp was best choice lucky I had a extra boost clamp like the one in the kit

    But over all I am very pleased with the kit and id recommend it to anyone wanting a better turbo


  8. Best money spent 5 Star Review

    Posted by on Apr 12th 2016

    The GTP38R turbo is great truck a lot quicker and only have to feather and had lots of power also got RiffRaffs boot kit intake heater delete plug and they have the best prices nobody else could beat the price on turbo my Truck is 2001 250 other mods on it is diamond 4 inch diamond eye exhaust ,TYMAR cold air intake,&TS 6 position chip with the informant


  9. One of the best aftermarket upgrade to date 5 Star Review

    Posted by on Mar 23rd 2016

    I have a dp tuner, regulated fuel return, 4" exhaust turbo back, cold air intake, and factory injectors.

    Before I had the stock turbo with a WW and now with the 38r I have a lot more torque espically at and above the 1800 RPM mark. I read about how loud they were but it is very close to the factory turbo with a wicked wheel.

    As far as boost levels go I seeing a max of 32psi and big drop in EGTs. I wil only hit 1000 degrees (unloaded) if I am on a long hill and lugging in OD. I did get the ceramic coated up pipes and had the turbo ceramic coated as well. I don't know if that is why I am seeing higher than average boost numbers but I love it.

    I would recommend a cold air intake first. It will let your new turbo breath and give you something to hook the new 4" boot to.


  10. Great! 5 Star Review
