Thumbnail Filmstrip of 1994-2003 7.3L Powerstroke Wicked Wheel 2 DieselSite WW38 Images
The DieselSite WW38 is the Wicked Wheel 2 compressor wheel for a stock 7.3 turbo. It fits a TP38 and a GTP38 from 1994 to 2003. It is not the wheel for a GTP38R. That turbo uses the WW38R.
The stock cast wheel is what surges on these trucks, the bark on lift-throttle. This billet wheel is DieselSite’s fix for that, and it spools harder than the cast wheel it replaces. It is factory balanced, so the turbo does not need a rebalance. The thread is standard right-hand. Turn it left to loosen, snug it until it seats, and it tightens itself. Do not use an impact. Mark the compressor cover before it comes off.
DieselSite says keep the wastegate on a 1999–2003 truck and stay under about 32 psi if you want the stock turbo to live. The turbine wheel and the housings stay.
Replace the compressor-housing O-ring while the cover is off. A new wheel on a flat ring will still leak boost.

The wheel is ok, makes a good sound and all that but without doing the back wheel too it doesn�t balance out well so truck didn�t have much of a difference. Didn�t notice any difference in boost really. I plan to buy a new turbo soon though. FFD definitely has quality products this just didn�t what I was thinking it would.
