*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. 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!


  2. 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


  3. 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


  4. Best upgrade so far 4 Star Review

    Posted by on Apr 22nd 2015

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


  5. 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


  6. 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.


  7. 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


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

    Posted by on Jan 19th 2015

    I spent countless hours reviewing Turbo upgrade parts and kits, I figured the heck with it,I bought the 38r..Plus Riffraff has 'em on sale…What an awesome upgrade…Thanks Clay!!


  9. Garrett gtp 38r 5 Star Review

    Posted by on Jan 8th 2015

    Love the sound it makes and the quick response it has when needed


  10. For the money, great replacement for my old turbo 5 Star Review

    Posted by on Dec 2nd 2014

    It's an excellent stock turbo replacement. I had some trouble fitting the intake boot to the turbocharger, but it went in after a little finagling. I'm bone stock other than this turbo and a T500 hpop. I didn't notice any increase in fuel economy, nor any power increase, but again I'm bone stock. I replaced my old turbo just because it had 200k on it. I feel so far this turbo works perfectly as a stock replacement. With mods, I'm sure it would outperform the stock turbo, but it works exactly as it should as a plug and play, long lasting stock replacement.
