Compressor wheel bore to small for shaft
Jkole4 14 Jan 2018
Hi I bought a new comp wheel for my turbo and the shaftbore is to small so it doesn't fit on the turbo. The turbo is a gt3071r could I just drill it out to fit or do I need to get it professionally done?

No you can't just drill it through. it needs to be bored out with a special cutter with tolerances of almost 0 thou. If the comp wheel is out your whole shaft will bend once comp nut is torqued.
