*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. 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

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

  3. Garrett gtp 38r 5 Star Review

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

  4. 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.

    Needed another turbo since mine crapped out, decided to purchase this. Inlet is larger, makes a huge difference in performance, also upgraded to a WWII.

  7. Damn good turbo! 5 Star Review

    Posted by on Aug 13th 2014

    10-15psi of boost on normal acceleration, spoils up really fast and I love the loud whistle it gives.

  8. almost 5star good 4 Star Review

    Posted by on Jul 14th 2014

    This turbo spools fast. Huge difference from stock turbo.

  9. Pleasent upgrade ! 4 Star Review

    Posted by on Jun 18th 2014

    Nice to have a new style turbo easier for other upgrades and of course nicer turbo sounds can't wait to see the milage difference I went from the smaller early 99 7.3 turbo

  10. Too cool!!! 5 Star Review

    Posted by on May 3rd 2014

    Didn't need it but had to blow the tax refund on something fun this year. Great sound! A lot of intake whistle compared to the stock turbo. Didn't notice much extra spool time even though it's bigger. What I did notice was lower EGTs around town by around 100 degrees and lower up to around 60 (I have a manual with the 3.83 rear end). After 70 it runs around 100 degrees hotter with significantly less boost on flat ground but it has no problems spooling up when you need it to. Install instructions were great with pictures included. Took me around five hours and a six pack on a nice afternoon. If you have the money this is a great upgrade especially with supporting mods. One thing I forgot to do until after it was in was adjust the linkage on the waste gate (Mine came set at 15psi). It's a royal pain to do after it's in especially when you lose the little clip.
