In my search for mating an Allison w/ the 6.2L L92 in the H2 (2008/2009) (I'm learning here, so if there's an obvious answer, don't flame, lol), I came across a thread on another forum discussing this swap for the H3 Alpha.

These guys here will do the swap. It sounds like it's a turn key solution, but it's not specifically stated, albeit, they claim all features are intact:

I'm in no way affiliated with this group (just found out about them today). I'm curious what you guys think. I don't know the cost, but is it something you guys with Alphas would consider? To all the I5 guys, sorry, it doesn't seem doable.


Edit:

Maybe a better question to ask is, "has anyone actually done this yet?"

I see that it's been discussed here, directly w/ tbm, but I have yet to see anyone posting that it's been done & worth it or not worth it.

 

Looks interesting, I wish the site had more info, but its worth checking out.
