Wondering if anyone knows which transmission is stronger, I figure the red sport is more up to date and I believe I heard they added more clutches to the red sports transmission. Wasn’t sure if the m56 was any beefier. This is all because I want to swap an m56 engine into my g37

 

Supposedly, the red sport tranny could take up to 600 whp from what I've gathered.

 

Has this swap been done before? Would it be easier to try to fit the 5.0 engine since it was made for the FX which is all the same **** as the G37 right
