what size are the bolts that attach the 02 housing to the hot side

 

ne one

 

10mm 1.25

I highly suggest you get factory mitsubishi bolts that are specific for the turbo to o2 housing. They are heat treated, and of very high quality. Hardware store crap will rust and sieze within weeks. Then it will snap off and make a giant hassle, if not ruin your turbine housing when you need to get it apart in the future.
