1.00 A/R turbine housing for free flowing exhaust with reduced back pressure and

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. Also, install aftermarket wheels or opening up the turbo will void the manufacturer warranty.

  1. Absolutely amazing! 4 Star Review

    Posted by on Sep 19th 2017

    I made this purchased after the turbine shaft came apart on my stock GTP38. I was immediately impressed by the response time of this turbo. On my stock turbo I could floor it and it would take a few seconds to get to 20-22 psi but this GTP38R scares me ( in a good way). I floored it for the first time the other day (was scared to do since my truck has 237K+ miles and the previous owner hadn't done a good job keeping up with it), before I could even look up at my gauge it had already registered 25+ psi! The only reason it doesn't get 5 stars in my book is it's loud. There's a whine from this turbo when it's spooled and I'll grow used to it but others may not be able to handle it.

  2. Great boost increase! 5 Star Review

  4. Turbo replacement 4 Star Review

    Posted by on Jul 17th 2017

    Easy to replace with no modifications required. I bought it because my stock one needed to be rebuilt and it was a factory replacement

  5. Nothing is ever easy. But worth it 5 Star Review

    Posted by on Jun 25th 2017

    2000 f250 7.3 did the danjo bolts CVDs oil cross over FRX fuel and 38r tubo hardiest thing too do on turbo swap is hooking it up to the up pipes before u can put it on the pedestal. Me and the up pipes had words.
    EGTs are around 500degs at 75 that's around 150 to 200degs cooler then before have not taken any long trips wit too check fuel miles.

  6. engineering at its best 5 Star Review

    Posted by on May 15th 2017

    great product not only looks well engineered but preforms great also. I am very pleased with the purchase of the 38r, the boost increase over the stock turbo is unreal. I don't hear the whistle sound that some 38r owners talk about, I have a lot of other mods like headers, free flowing filter system (not k&n) and lightly ported heads maybe that has a lot to do with the sound. thanks riff raff

  7. I love it 5 Star Review

  8. AWESOME TURBO 5 Star Review

    Posted by on Mar 16th 2017

    Ordered from RIFF RAFF. Very fast shipping. Turbo went on fairly easily with hand tools. Turbo definitely has a different sound, whistles but kinda sounds like a supercharger or star wars laser gona when you let off the throttle. I love it@

  9. Don't hesitate 5 Star Review

    Posted by on Feb 21st 2017

    I spent over a year trying to figure out what kind of turbo set up to go with for my tuned 2001 F250 w/ZF6. Thought about H2e, etc... I just installed the 38r with a billet wheel and up pipes (ceramic coated) and am completely satisfied. Sounds awesome, spool up is lighting quick and she can burn 35" rubber with ease. Price and service excellent from riff raff. Thanks!!!!

  10. Best Price! 5 Star Review

    Posted by on Jan 27th 2017
