WW2 install
got the wicked wheel and was hopping to not pull the turbo. looks like you don't have too, until you get to the last bolt behind the oil drain line. made 2 wrenches, one too get the oil drain bolt off and another to get the compressor housing bolt off. just not enough grab to get the wrench on the last housing bolt out. PULLING the Turbo is the only option. your better off getting a good drop in replacement if you have to pull the turbo out. makes it worth the time and headache.

Does this go in my stock turbo?
View Staff Answer 
yes, after you take the intake housing off of the turbo there's a nut that hold the stock wheel on (it has backwards threads.) you will need a impact wrench to take it off put the new one on and put it back together
