i am going to remove my turbo to install the wicked wheel. i ordered all the gaskets needed to put the turbo back on. my question is....once i get the turbo off do i have to split the turbo to hold the shaft that the comp wheel sits on? if so how? does the shaft also spin the exhaust side? i have never had a powerstroke turbo apart. so i guess the main question is how do i get the comp wheel off without an impact? thanks guys
