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. 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

  3. 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@

  4. 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!!!!

  5. Best Price! 5 Star Review

    I searched all over and this was by far the best pricing! You guys are awesome

  6. Shipping 4 Star Review

    Posted by on Jan 27th 2017

    The product was as expected the one complaint I do have however is when a person spends well over $1200 you just assume there would be free shipping that's in my mind is bad customer service

  7. Great Product, SUPER PRICE 5 Star Review

    Posted by on Jan 21st 2017

  8. 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!

  9. 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.

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

    Posted by on Oct 9th 2016

    Shipping was fast got the 38r installed and working fine you can tell a difference. Now got to do stage 1 injectors
