The 38R model will produce more peak hp than the 66. If max power is important and you have larger injectors - the 38R model will be better. This turbo has a standard right hand thread - meaning you turn the compressor wheel to the left to loosen. No need to torque the Wicked Wheel on.
Simply snug the Wicked Wheel until it fully seats. It will self-tighten to full torque. The Wicked Wheel is balanced at the factory. Turbo balancing after installation is not necessary. DO NOT USE AN IMPACT WRENCH TO CHANGE TURBO WHEELS!Impact wrenches cause stress fractures in the shaft that will cause failure either very soon or thousands of miles down the road. It's like a crack in your windshield that grows over time. Take your time and remove the turbo, hold onto the turbine shaft and remove the compressor wheel with an open end wrench. Before pulling off the compressor cover: The compressor cover can rotate 360 degrees. To eliminate you having to find the right index again after re-assembly, using a marker, mark a line across the break in the separation joint in the cover in two different spots.
When you re-assemble the housing, you simply line up your old lines and you will save yourself a lot of time. Below is a dyno graph taken at Power Hungry Performance on Jason's truck. This truck has 250/200 injectors, GTP38R, and PHP tuning. Results are with only a wheel change.No tuning has been done to try to take advantage of the new found air volume.
