*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.

This turbo is good if you are running stage 2 injectors or smaller. I had it on my truck with 205/30cc injectors for about 10k miles. Turbo is not having it. I am switching to the 66/73 kc turbo. It's meant for bigger injectors. The bearing are what went out in my 38r. Makes a growling noise where there should be a whistle
Easy to install. Came Packed nice. And sounds and performs good
Intake boot doesn’t fit worth a darn, will have to trim, get frustrated and settle with a half collapsed intake boot. Intake is much larger than stock and won’t work with stock intake parts.
Thanks for the great service and fast shipping!
awesome turbo quick delivery.
Installed along with new manifolds, up-pipes, pedestal, and ebpv delete. Quite a bit louder with the ball bearing design as others have noted but doesn't bother me. I drive with the windows down 90% of the time anyway. Im sure the 6637 filter doesn't help. Still running stock fuel plus the FRX so it takes a bit more to spool in the lower RPM range but fuel mods are next. Can still build 30 psi at wot. EGTs are relatively the same but haven't pulled anything to see loaded temps yet. No more compressor surge thankfully. Surprised it didn't come with new mounting bolts for the turbo to pedestal. Old ones looked fine so reused them. Overall very pleased.
This turbo works fine and was installed easily as a direct replacement for the stock turbo. However, this did not do what many had claimed. The change to power was minimal at best, and I really didn't even notice much of a drop in EGT's. If you have to replace a broken or bad turbo, probably a good choice. As an upgrade- I'd likely look to something else. FYI, this was installed on a 7.3 with full 4" exhaust, DP Tuner 80hp tune, EBP delete, factory injectors, HPOP, and intake..
Very happy and pleased.. shipped fast and works great! Definitely will be ordering more stuff from riffraff
Install was very simple on my 01 F350 since I've taken my turbo out a few times in the past. This is truly a drop in turbo and everything fits nicely. If you dont already have them, definitely get the high flow outlet, ebpv delete pedestal and a few more exhaust/intake clamps if you want your life to be easier. The only reason I'm giving this 4 stars is because they really should have an upgraded compressor wheel already built into this kit. Going from a wicked wheel on a stock GTP38 to this turbo there is a noticeable lag on the spool time and egts are slightly higher with the larger exhaust housing. That being said, the whistle is crazy loud and this thing will pump out crazy boost if tuned right. Would recommend to anyone with injector, exhaust, and fuel upgrades in mind.
