    Non MHI TD05 16G turbocharger oil feed adapter

    Does anyone know off hand what oil feed adapter thread pitch/size I need for a non-MHI 16G turbocharger? I went to transfer the parts off my MHI TD05 big 16G turbocharger and the oil feed adapter is too big for the non-MHI turbocharger. Had the old set-up with an adapter to fit 4an oil feed line.

    Edit: Finally, found my pitch gauge after an hour of searching. The correct size is a M10 X 1.5, at least for this turbocharger. It was a non-MHI in a box with a DNA company logo if that helps anyone in the future looking for oil feed sizes. The kit that is with the turbo comes with an oil feed fitting that is M10 X 1.25

    I find it odd that any 16G, MHI or not, would deviate from the default M12 x 1.25 thread.

    FWIW, 9B turbos have an M10 x 1.25 thread size and pitch.

    Myself included, but the M10 x 1.25 and M12 x 1.25 fittings don't fit. Even the supplied bolts with the turbo didn't fit. I double checked the pitch and it is 1.5 on the turbocharger. I had a M10 x 1.5 bolt and it threads in perfectly. Has anyone else noticed any deviations like this on the non-MHI turbochargers?

    WRX 13T turbos have an M10 x 1.5 thread.
