Product Description

The 88mm GT compressor wheel provides 33% more flow than the stock 80mm wheel. 
Ported shroud housing improves compressor flow range for surge control 
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. Really enjoy this turbo!! 5 Star Review

    Posted by on Aug 26th 2015

    It was a straight forward installation and the addition of this turbo really took advantage of the 160/30% over sized injectors and the T500. These trucks should have come with this turbo from the factory. The quality is oustanding, and with my set-up, it's not laggy. The whistle and performance is intoxicating.

  2. Awesome upgrade and awesome service from Clay as usual! 5 Star Review

    Posted by on Aug 13th 2015

    Stock turbo quite literally blew apart, so my hand was forced. Already have 238/80 injectors in the truck, and with the tunes from Gearhead the 38R is a phenomenal upgrade. Quick to spool, smooth even power delivery, and of course that whistle! 6.0's have nothing on the sound it makes.

    Love love LOVE this turbo, absolute must if you're looking to upgrade your 7.3.

    As usual, huge shout out to Clay for his amazing service and always returning phone calls the same day!

  3. Makes a great truck AWESOME! 5 Star Review

    Posted by on Jun 1st 2015

    My turbo bit the dust and I had to replace it. This was a no brainer to me...the truck is 15 years old and I plan to keep for at least another 15! This is the way to go. Roller bearings are what should be on the stock turbo and 4 inch in only makes sense(there rest is 4 inch...why are you cutting it to 3 inch on the stock turbo?) This thing is a great upgrade. Spool up is almost instantaneous!

  4. A must have for all 7.3 owners 5 Star Review

    Posted by on May 8th 2015

    Let me just say that this turbo was more than what i expected. Amazing performance and sound ! Lower egt ,more power and quicker spool up.
    Clay has been nothing but helpful with my questions A 1 Customer service

  5. 38r w billet wheel 5 Star Review

    Posted by on Apr 27th 2015

    This is what a 7.3 should have been from factory, I had a great custom ( stock) turbo that worked very well for towing and daily driving, when I put this turbo on, it completely changed the I felt about keeping it stock. It spools like lightening and tows like it is on steroids. If you own a 7.3 and don't have one then you are missing out on what your truck can actually do. Just wish I got one sooner

  6. Best upgrade so far 4 Star Review

    Posted by on Apr 22nd 2015

    Compliments my stage I sticks well. Best price I could find.

  7. great turbo grade 5 Star Review

    Posted by on Apr 1st 2015

    Great up grade from stock did complete boots clamps intake inserts pedestal delete turbo with tune I have builds up to 35lbs boost works great great sound quick response

  8. Best drop in upgrade by far 5 Star Review

    Posted by on Mar 29th 2015

    I am absolutely impressed. Spool up time is great, sounds very very nice. RiffRaff had the turbo at my door in around 3 days. EGT's are down by ~100-150 degrees. Definately a nice upgrade from the stock turbo.

    Pushin about 7-10lb boost cruising with no load at 55-60mph. Seeing around 20-25 lb boost WOT in combination with the tunes I have.

    One of the best purchases I have made for my truck for sure.

  9. sounds great 5 Star Review

    Posted by on Mar 20th 2015

    Great upgrade not as loud as I thought it would be but you can still hear the spool up :) you can definitely tell there is more air flow seeing it out performs my stock turbo with a ww. And not needing as much boost. I also installed a billet wheel before I installed much lighter then the stock wheel that comes with the turbo

  10. didn't want to just rebuild the Turbo 5 Star Review

    Posted by on Jan 19th 2015
