I have the dimensions of both of the blowers if needed. The bolt pattern is not far off but the MP112 manifold cannot be drilled for it as the bolt holes are too close and would break through. I actually was in the process of purchasing an MP112 from Brian @ superchargersonline a few weeks back but pulled back on the decision because of the mounting issues. However, a TVS1900 will bolt right on...

Wonder how much those head units sell for..... I got a decent deal on the 122

I was thinking a 1/2 spacer... Bolt to mp122 and then have it bolt to the manifold. What do you think?

If you can machine, then a 1/2" spacer would be sufficient.

Brian was selling the MP122 for $850 brand new. I believe the pulley alignment would also need to be worked on as well.

You could fill the holes but because it is aluminum, heli-arcing would need to be done.

There ya go , plug weld the holes and re tap for the 122 or have a custom spacer made

check the dimensions but if I remember right the overhang was to the rear so the front mounting holes on the blower HU would be the same and you would maintain pulley alignment, however, I had an early unit and had to flip the blower pulley.

Can these 122 really make that much difference over a 112?

couple of advantages, 1) slightly larger 2) more twist on the rotors. Mine ripped at 10lbs of boost on a 6L. I made 430rwhp with 112 @ 7lbs of boost.

Here is a comparison of the MP112 and MP122's dimensions. This is from an 2010 Magnuson catalog I found online.

As you can see, assuming the snouts being used are the same, the MP122 will stick out about .200" further than if it were being used on the MP112. Also you can see the mounting pattern is just slightly different.
