I was just wondering if anyone's come across a good thread on swapping the VG33ER's Eaton M62 supercharger with an Eaton M90? It appears to have been done as I can find pics of it on the web, but I haven't found any good info on the swap. I would imagine a new adapter plate would need to be fabricate among a few other things...

Advantages? Boost, longevity...?

Boost...but I'm asking more out of curiosity and learning about the swap itself. It's probably not something I'm going to do on my own engine with 200,000 miles on it!

If the compression is still good I would swap head gaskets and do it if it were me

How much boost can the m90 push? What do they come out of?

They use them in GM's and Fords and I think the one they're putting on the VG33ER is a M90 Gen 3 running around 12 psi boost from a GM car. I'm sure it's going to need a few mods like bigger injectors, exhaust and such. That's why I'm looking for a good thread on the swap so I can learn what's involved and the pros and cons as well as cost of the swap.
