Perfect rebuild for stock turbo. Couldn't ask for a better product. And as always riff raff got it here quick with no issues.

Well made, easy install. More boost.

Very easy to install. Can’t tell a huge difference but it’s worth the price I feel.

Seem to be made at a high standards. It spools faster and got rid of the surge I had towing. The video is straight forward and easy to follow.

HIGHLY recommend. Excellent quality. This kit and the EBPV delete took me from less than 24lbs of boost to over 31lbs boost AND reduced peak EGT by over 100deg. BUY NOW!

I had compounding leaks ie. Up pipe exhaust leak, turbo pedistal leak, severe hpop oil leak. Replaces all of the above and on removal and inspection of the turbo my compressor wheel was severely chewed up so I replaced it with the KC ballenced assembly from Riff Raff along with the 6637 air filter and couldn't be happier. Installation was straight forward with a precision fit. The power band is night and day and doesn't stop pulling through high rpm's . Would recommend to anyone Looking for a mild build yet remaing reliable. I would also recommend exhaust and intake for full turbo potential, this thing need a lot of air.

Ordered Friday and arrived Monday. Installed along with the deleted pedestal, big head actuator and High Flow outlet. Very pleased! Truck has PHP Hydra with canned 1023 tunes that I’ve ran for over a year on a stock turbo. This blows it away. More boost sooner plus lower egts. Noticeably more power on every setting of the Hydra. Sounds awesome and only gets better the faster it spools.when you shut down you can hear it coast way longer than the stock assembly, perhaps mine was on its last leg. Truck never threw boost code before but can easily now. Time for a Riffraff boost fooler!

Great response, builds boost at1200 rpm & have seen 28 lbs @ 2500 with no load on 8% grade. Boost fluctuates with conditions in traffic, no lag or hesitation. Impeller seems more aggressive than stock and compressor wheel has larger mail vanes with the addition of smaller secondary vanes. Very tight fit into housing, (1.00A/R).

Did this on 1996 that I already installed a banks intercooler on.
Installed the riffraff up-pipes, changed the exhaust housing to a 1.0, and removed the EVBP and at the same time. Up-pipes, collector, exhaust and outlet housing and down-pipe are all ceramic coated.
With all of that the truck runs much better, more boost sooner, and way more responsive, stays cooler too!
Running the generic PHP tunes on the Hydra.
Been towing with it weighing in around 15-16k combined, much more enjoyable to drive.
Since my compressor housing was cracked, the turbo is basically new at this point. Probably could have just bought a whole drop-in turbo at this point but I have no regrets
