*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. GTP38R Turbo 5 Star Review

    Posted by on Mar 4th 2018

    Great turbo option if not changing over to a T4 style. Less smoke, reduced EGT and perfect fit. The turbo kit does not have the out let O-Ring for the intake manifold and the 12pt housing bolts are included. This is missing from the product description. Stock sticks will light but I recommend running a tuner. With my DP-Tuner on the 60hp setting the truck runs so well higher hp setting are not necessary. With the addition of a Terminator HPOP rebuild, FRX and 38R I can't even imagine what new sticks would be like. At 177K the truck is running extremely well with the top-end tune up.

  2. Impressive Turbo, Great Price, expected a little more from it 4 Star Review

    Posted by on Feb 12th 2018

    I did a lot of research before buying a new turbo for my truck. I do a lot of hauling 14k pound load average. Also use my truck as my daily driver. Riff Raff was definitely the best price for this turbo! How ever you have to adjust the shaft to get the boost they say you can get. Has turbo surge, which i thought was ridiculous for a 1300 dollar brand new turbo. EGTs only drop in specific situations and in specific gears and RPMs and speeds. Over all EGTs have gone up some. Spools crazy fast and can make great boost and added a lot of power to my truck.
    Great turbo with great power but I dont feel like the turbo meets all the hype that others have seen.

  3. Love this turbo! Should have put it on the day i got my 7.3!! 5 Star Review

    Posted by on Jan 2nd 2018

    Direct fit with no modifications required. Thing has no turbo lag compared to stock, i get better mpg and it sounds amazing. Best thing ive done to the 7.3 so far! Makes 27-29lbs unloaded on stock fule with a chip. If you're in the fence about this kit id go for it its bad ass!

  4. 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.

  5. Great boost increase! 5 Star Review

    Posted by on Sep 7th 2017

    What a performance difference! So glad I went with this Garrett.

  6. GTP38R great turbo! 5 Star Review

    Posted by on Aug 31st 2017

    As advertised, really like it on our Excursion. Lots oF whistle and whine! Builds boost quick.

  7. 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

  8. 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.

  9. 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
